  • characterization of Frankliniella occidentalis and Frankliniella bispinosa thysanoptera thripidae injury to strawberry
    Journal of Economic Entomology, 2021
    Co-Authors: Iris Strzyzewski, Joe Funderburk, Justin M Renkema, Hugh A Smith
    Abstract:

    Frankliniella flower thrips are pests of numerous fruit and vegetable crops as they feed and reproduce in the flowers and fruits. The invasive Frankliniella occidentalis (Pergande) from the Southwestern United States, an economic pest in Florida since 2005, and the native Frankliniella bispinosa Morgan are both found in Florida strawberries. The objective of this research was to characterize injury to strawberry fruit from these species. Densities of 0, 2, 4, 8, 16, or 32 adult females of each species were caged on a strawberry plant with one flower. The cages were removed after 2, 5, or 10 d, and the number of surviving adults and the number of larvae determined. Injury was quantified on the mature fruit 21 d after thrips were introduced onto the experimental plant. Initial densities as low as two adult F. occidentalis females per flower decreased fruit set and increased cat-facing on the fruits that developed. There were no significant effects on fruit set and cat-facing by any initial density of F. bispinosa. Feeding by thrips on the small, green fruit affected the size and shape of the mature fruit: the diameters were decreased as a linear function of increased feeding by F. bispinosa, and the weights were decreased as a linear function of increased feeding by F. occidentalis. Overall, results showed that F. occidentalis was more damaging to strawberry than F. bispinosa. The differences in pest status between these common flower thrips species in Florida presents challenges to management programs.

  • sampling for estimating Frankliniella species flower thrips and orius species predators in field experiments
    Journal of Visualized Experiments, 2019
    Co-Authors: Joe Funderburk, Thomas Skarlinsky, Iris Strzyzewski, Xavier Martini, Josh Freeman, Edward Traczyk, Scott Adkins
    Abstract:

    The western flower thrips, Frankliniella occidentalis (Pergande), is a polyphagous pest that has been spread worldwide. The extensive use of insecticides in attempts to control its populations eliminates natural enemies and competitor flower thrips species, thereby increasing its populations. An unsustainable situation develops with concomitant resistant pest populations, secondary pest outbreaks, and environmental degradation. Integrated pest management utilizes knowledge of pest and natural enemy relationships to implement tactics that are environmentally friendly and sustainable. Minute pirate bugs are the most important worldwide predators of thrips. They can suppress and ultimately control Frankliniella species flower thrips. Flower samples taken at least weekly are needed to understand predator-prey dynamics. Shown here is the sampling of the flowers of fruiting vegetables and companion plants to estimate the densities of individual thrips and minute pirate bug species. Representative data illustrates how the protocol is used to determine the efficacy of management tactics over time and how to evaluate the benefits of predation by minute pirate bugs. The sampling protocol is similarly adaptable to sampling thrips and minute pirate bugs in other plant species hosts.

  • a key to some Frankliniella thysanoptera thripidae larvae found in florida with descriptions of the first instar of select species
    Florida Entomologist, 2016
    Co-Authors: Thomas Skarlinsky, Joe Funderburk
    Abstract:

    Few publications exist toward the identification of larval thrips. As a result, researchers and practitioners often are unable to report larval species data or may misinterpret what is a host plant when adults of multiple species are collected. Therefore, we conducted repetitive plant sampling and detailed examination of larvae with adults, which revealed morphological differences of some undescribed Frankliniella (Thysanoptera: Thripidae) larvae. The morphological differences were confirmed by non-destructive DNA extraction, PCR, and sequencing of the COI mitochondrial gene. A larva II morphological key to 7 Frankliniella species found in Florida is presented with new larval descriptions of 4 species.

  • thrips thysanoptera collected from solanum dulcamara solanales solanaceae in washington and idaho
    Florida Entomologist, 2016
    Co-Authors: Carmen Castillo I Carrillo, Joe Funderburk, William E Snyder
    Abstract:

    Summary Bittersweet nightshade, Solanum dulcamara L. (Solanales: Solanaceae), was sampled at numerous locations in Washington and Idaho. Adults of 8 species of thrips (Thysanoptera) from 3 families were collected, including the worldwide plant pests Frankliniella occidentalis (Pergande) and Thrips tabaci Lindeman (Thripidae), which are vectors of the serious plant viruses in the genus Tospovirus. Aeolothrips fasciatus Hinds (Aeolothripidae), a predator of small insects, also was collected.

  • effect of insecticide rotations on density and species composition of thrips thysanoptera in florida strawberry rosales rosaceae
    Florida Entomologist, 2016
    Co-Authors: Jeffrey D Cluever, Joe Funderburk, Hugh A Smith, Curtis A Nagle, Galen Frantz
    Abstract:

    Abstract Feeding by Frankliniella (Thysanoptera: Thripidae) thrips causes economic damage to strawberry (Fragaria ananassa Duchesne; Rosales: Rosaceae) crops in Florida and in other production regions worldwide. Resistance to spinosyn insecticides, particularly in Frankliniella occidentalis (Pergande), is a major concern for strawberry and other crops. Experiments were carried out in 2014 and 2015 to evaluate the effect of 6 insecticide programs on the numbers and species composition of thrips attacking strawberry on a season-long basis in Florida. Five insecticide programs included spinetoram applied once, twice, or 3 times in the rotation, alternated with acetamiprid, cyantraniliprole (Cyazypyr®), novaluron, sulfoxaflor, and/or tolfenpyrad. Also included in the treatments were bifenthrin and a non-treated check. Thrips densities were sampled weekly in flowers, and in both flowers and fruits in 2015, 2 d after treatment applications. The primary thrips species recovered from strawberry flowers and fruit ...

  • Vegetación espontánea en el cinturón hortícola platense hospedante de Thripidae (Thysanoptera) vectores de Tospovirus: riesgo relativo como componente epidemiológico
    Ediciones INTA, 2019
    Co-Authors: Carrizo Paola, Amela García, María Teresa
    Abstract:

    La peste negra es una virosis causada por el Tomato Spotted Wilt Virus (TSWV), transmitida por trips y representa un problema complejo ya que las malezas hospedantes para los trips vectores y el virus acentuado como reservorio del virus y sustento de los vectores. El objetivo fue generar, a partir de una lista de malezas que actúan como hospedantes de las cuatro especies de trips vectores en el cinturón hortícola platense, una categorización de riesgo relativo como componente epidemiológico. Entre 2000 y 2003 se seleccionaron tres sitios dentro del cinturón hortícola platense (Buenos Aires, Argentina) donde se realizaron muestreos mensuales (60 en total) en flores de 21 malezas hospedantes de Frankliniella occidentalis, Frankliniella schultzei, Frankliniella gemina y Thrips tabaci. Para su análisis, los resultados de los muestreos fueron agrupados en tres estaciones anuales, en correspondencia con la fenología de los cultivos en invernadero en la región. Para los cuatro trips vectores, se consideró la abundancia de trips adultos y la presencia de sus larvas, mediante un análisis cluster, jerárquico y no supervisado, y la prueba DGC de comparación de medias multivariada para obtener el número de grupos significativos. A partir de este agrupamiento de base, fueron definidos tres grupos de riesgo (GR) como fuente de inóculo de estos vectores: alto (A), medio (M) y bajo (B) según el estatus de hospedantes reproductivas (HR). Los grupos que surgieron fueron: (A): HR de F. occidentalis, (M): HR de F. schultzei y T. tabaci, y (B): HR de F. gemina o de trips no vectores. Se propone el relevamiento periódico y la supresión temprana de la floración de nueve especies de malezas categorizadas como de riesgo alto. Ello implica el monitoreo continuo de tres especies de malezas, a las cuales se les suman otras acompañantes según la estación de crecimiento.The Tomato Spotted Wilt Virus (TSWV) is a thrips transmitted virus and a complex problem since weeds are hosts of the vectors and also of the virus, then those plant species may act as reservoir and vector support. The objective was to obtain, from a list of weeds previously known as hosts of the four vector thrips species in the La Plata horticultural belt, a categorization of relative risk as epidemiological component. Between 2000 and 2003, three sites were selected within the horticultural belt of La Plata (Buenos Aires, Argentina), where samples (total = 60) were collected from flowers of 21 weeds, known as hosts of Frankliniella occidentalis, Frankliniella schultzei, Frankliniella gemina and Thrips tabaci. For their analysis, the results of the samplings were grouped in three annual seasons, in correspondence with the phenology of the greenhouse crops in the region. For the four species of thrips known as vectors, were considered the adult abundance and the presence of their larvae. It was cluster analysis, hierarchical and unsupervised, and then the DGC multivariate means test, were used to obtain the number of significant groups. From this early grouping, three risk groups (RG) were defined as a source of inoculum of these vectors: high (H), medium (M) and low (L), according to their previously known status as reproductive hosts (RH). The groups that emerged were: (H): RH of F. occidentalis, (M): RH of F. schultzei and T. tabaci, and (L): RH of F. gemina or RH of non-vector thrips. The proposal focuses on the periodic survey and early suppression of flowering of nine weed species categorized as RG (H). This involves the continuous survey of three species of weeds, to which are added other companions according to the growing season.Gerencia de Comunicación Institucional, DG SICyP, INTAFil: Carrizo, Paola.

    Abstract:

    El virus de la peste negra (TSWV) es un Bunyaviridae que causa diferentes síntomas a las plantas, incluso la muerte. En Argentina existen 4 especies de tisanópteros transmisoras: Frankliniella occidentalis, Frankliniella schultzei, Frankliniella gemina y Thrips tabaci. El objetivo del estudio fue conocer las plantas de la vegetación espontánea circundante a los invernaderos de pimiento que actúan como hospedantes verdaderas (de reproducción) de los trips vectores mediante identificación de adultos y de larvas. El estudio se llevó a cabo en tres sitios ubicados en el cinturón hortícola platense (Buenos Aires, Argentina). Durante los años 2000 a 2003 se realizaron relevamientos mensuales en las áreas de los establecimientos en donde no se lleva a cabo el control de las malezas, extrayendo flores de la vegetación espontánea. A través de 60 fechas de muestreo se recolectaron y procesaron 14.636 flores de la vegetación espontánea de las cuales se obtuvieron 54.050 individuos de Thysanoptera, 40.356 adultos (96,96% Thripidae y 3,04% Phlaeothripidae) y 13.694 larvas de primer y segundo estadio (94,1% Thripidae vs. 5,9% Aeolothripidae y Phlaeothripidae). Se registró la presencia de las cuatro especies de trips vectores en el área. La familia botánica no mostró relación con la presencia de trips vectores, ya sea como adulto o larva. De las 40 especies de la vegetación espontánea relevadas resultaron: 19 no hospedantes (NoH), 21 hospedantes de alimentación (HA), 18 hospedantes reproductivos (HR) tanto en sentido amplio (18 sp.) como en sentido estricto (11 sp.) para una, dos, tres o las cuatro especies.The tomato spotted wilt virus (TSWV) is a Bunyaviridae that causes different symptoms to plants, even death.

The four species seem to have very similar requirements, due the overlap respect to their feeding and breeding hosts. The botanical family was not related to the presence of thrips vectors, neither in adult or larval stage. Out of 40 surveyed weed species, 19 resulted non-host (NoH), 21 feeding host (HA), and the remnant 19, reproductive hosts (HR), (18 in wide sense and 11 in strict sense) for one, two, three or four species of thrips.Gerencia de Comunicación e Imagen InstitucionalFil: Carrizo, Paola.

  • REGISTRO DE Frankliniella brevicaulis HOOD (THYSANOPTERA: THRIPIDAE) EM BANANA COMPRIDA (CV. D’ANGOLA) NO ESTADO DO ACRE
    'Revista Biota Amazonia', 2021
    Co-Authors: Santos, Rodrigo Souza, Sutil, Weidson Plauter, Lima, Élison Fabrício Bezerra
    Abstract:

    Thrips are among the insects harmful to banana cultivation in Brazil, usually depreciating the external aspect of the fruits by the formation of spots or eruptions on their skin, as a result of their food. This work makes the first report of Frankliniella brevicaulis Hood (Thysanoptera: Thripidae) in a commercial plantation of ‘banana comprida’ plantain (cv. D’Angola) in the state of Acre, Brazil. Due to the lack of information about the economic impacts and geographical distribution of this thrips species, research on this subject is strongly recommended in the State.Keywords: Amazon; Phytophagous insect; Terebrantia; Eruption thrips.Tripes estão entre os insetos prejudiciais ao cultivo da banana no Brasil, normalmente depreciando o aspecto externo dos frutos pela formação de manchas ou erupções em sua casca, em consequência da sua alimentação.

Devido à falta de informações acerca dos impactos econômicos e distribuição geográfica dessa espécie de tripes, pesquisas nesse com esse enfoque são fortemente recomendas no Estado.Palavras-chave: Amazônia, Inseto fitófago, Terebrantia, Tripes-da-erupção

  • Thrips (Insecta: Thysanoptera) associated to Fabaceae species in the Brazilian Mid-North
    'Universidade de Sao Paulo Agencia USP de Gestao da Informacao Academica (AGUIA)', 2012
    Co-Authors: Lima, Élison Fabrício Bezerra
    Abstract:

    Foram coletados tripes em 25 das 40 espécies de fabáceas amostradas em quatro municípios do estado do Maranhão e em dois municípios do estado do Piauí. Foram examinados 818 exemplares de tripes pertencentes a 22 espécies. Doze foram identificadas: Bradinothrips musae (Hood, 1956); Caliothrips phaseoli (Hood, 1912); Dolichothrips indicus (Hood, 1919); Frankliniella brevicaulis Hood, 1937; F. gardeniae Moulton, 1948; F. insularis (Franklin, 1908); F. schultzei (Trybom, 1910); F. tritici (Fitch, 1855); Haplothrips gowdeyi (Franklin, 1908); Heliothrips haemorrhoidalis (Bouché, 1833); Salpingothrips minimus Hood, 1935 e Selenothrips rubrocinctus (Giard, 1901). Cinco são provavelmente novas espécies: Aulacothrips sp.; Frankliniella sp. 3; Hydatothrips sp.; Neohydatothrips sp. e Scolothrips sp. Não foi possível identificar cinco outras espécies, porque o conhecimento taxonômico de um gênero não ainda não está esclarecido (Xylaplothrips Priesner, 1928), porque as espécies pertencem a grupos próximos (Frankliniella sp. 1 e Frankliniella sp. 2) ou devido a diferenças, possivelmente intraespecíficas, com espécies descritas (Plesiothrips sp. e Scirtothrips sp.). Para 17 espécies de fabáceas foram estabelecidos os primeiros registros de associações com tripes. Dolichothrips indicus e Xylaplothrips sp. são novos registros de gêneros no Brasil. Além dessas, B. musae, F. gardeniae, F. tritici, Sa. minimus e Se. rubrocinctus são novos registros para o Meio-Norte do Brasil. Nessa sub-região, indivíduos amarelos e marrons de F. schultzei ocorrem simultaneamente. Foram estabelecidas as primeiras associações de Sa. minimus com espécies vegetais no Brasil. Algumas espécies de tripes conhecidas como pragas de fabáceas, principalmente no sul e sudeste do Brasil, não foram coletadas no Meio-Norte. Uma chave de identificação ilustrada foi elaborada. Os exemplares-testemunhas estão depositados na coleção do Departamento de Entomologia e Acarologia da Escola Superior de Agricultura Luiz de Queiroz, Universidade de São Paulo (ESALQ/USP).Thrips were collected on 25 out of 40 species of Fabaceae sampled in four municipalities in the state of Maranhão and two municipalities in the state of Piaui. A total of 818 thrips specimens, belonging to 22 species, were examined. From those species, twelve were identified: Bradinothrips musae (Hood, 1956); Caliothrips phaseoli (Hood, 1912); Dolichothrips indicus (Hood, 1919); Frankliniella brevicaulis Hood, 1937; F. gardeniae Moulton, 1948; F. insularis (Franklin, 1908); F. tritici (Fitch, 1855); F. schultzei (Trybom, 1910); Haplothrips gowdeyi (Franklin, 1908); Heliothrips haemorrhoidalis (Bouche, 1833); Salpingothrips minimus Hood, 1935 and Selenothrips rubrocinctus (Giard, 1901). Five probably belong to new species: Aulacothrips sp.; Frankliniella sp. 3; Hydatothrips sp.; Neohydatothrips sp. and Scolothrips sp. It was not possible to identify five other species, because the current taxonomic knowledge of one genus is not clear (Xylaplothrips Priesner, 1928) or the species belong to closely related groups (Frankliniella sp. 1 and Frankliniella sp. 2) or due to slight differences, possibly intraspecific, with described species (Plesiothrips sp. And Scirtothrips sp.). For 17 species of Fabaceae, the first records of association with thrips were established. Dolichothrips indicus and Xylaplothrips sp. are new records of genera in Brazil. In addition, B. musae, F. gardeniae, F. tritici, Sa. minimus and Se. rubrocinctus are new species records for the Mid-North. In this area, yellow and brown individuals of F. schultzei occur simultaneously. It was established the first association of Sa. minimus with plant species in Brazil. Some thrips species known as pests in Fabaceae in Brazil, mainly in southern and southeastern, were not found in Mid-North. An illustrated key was elaborated. Voucher-specimens are deposited in the collection of the Department of Entomology and Acarology, Escola Superior de Agricultura \"Luiz de Queiroz\", Universidade de São Paulo (ESALQ/USP)

  • variation within and between Frankliniella thrips species in host plant utilization
    Journal of Insect Science, 2011
    Co-Authors: Joe Funderburk, Stuart R Reitz, Ignacio Baez, Steve Olson
    Abstract:

    Anthophilous flower thrips in the genus Frankliniella (Thysanoptera: Thripidae) exploit ephemeral plant resources and therefore must be capable of successfully locating appropriate hosts on a repeated basis, yet little is known of interspecific and intraspecific variation in responses to host plant type and nutritional quality. Field trials were conducted over two seasons to determine if the abundance of males and females of three common Frankliniella species, F. occidentalis (Pergande), F. tritici (Fitch) and F. bispinosa (Morgan), their larvae, and a key predator, Orius insidiosus (Say) (Hemiptera: Anthocoridae) were affected by host plant type and plant nutritional quality. Two host plants, pepper, Capsicum annuum L. (Solanales: Solanaceae) and tomato, Solanum lycopersicum L. that vary in suitability for these species were examined, and their nutritional quality was manipulated by applying three levels of nitrogen fertilization (101 kg/ha, 202 kg/ha, 404 kg/ha). F. occidentalis females were more abundant in pepper than in tomato, but males did not show a differential response. Both sexes of F. tritici and F. bispinosa were more abundant in tomato than in pepper. Larval thrips were more abundant in pepper than in tomato. Likewise, O. insidiosus females and nymphs were more abundant in pepper than in tomato. Only F. occidentalis females showed a distinct response to nitrogen fertilization, with abundance increasing with fertilization. These results show that host plant utilization patterns vary among Frankliniella spp. and should not be generalized from results of the intensively studied F. occidentalis. Given the different pest status of these species and their differential abundance in pepper and tomato, it is critical that scouting programs include species identifications for proper management.

  • comparative bionomics of Frankliniella occidentalis and Frankliniella tritici
    Florida Entomologist, 2008
    Co-Authors: Stuart R Reitz
    Abstract:

    Two of the most abundant thrips in the south eastern USA are Frankliniella occidentalis (Per gande) and Frankliniella tritici (Fitch) (Thysan optera: Thripidae). Frankliniella occidentalis is a key pest because of damage caused by its feeding and oviposition in many crops and because it is a vector oiTomato spotted wilt virus (Childers 1997; Ullman et al. 1997). Although F. tritici is not a vector oiTomato spotted wilt virus (Assis Filho et al. 2005), its abundance and morphological simi larity to F. occidentalis makes it a management concern for growers and crop consultants (Reitz 2002). Despite superficial similarities in their habits and host plants, the seasonal population dynamics of these species differ dramatically (Eckel et al. 1996; Funderburk et al. 2000; Reitz et al. 2002), yet efforts to better understand their population dynamics are hindered by a lack of comparative biological data and because observ ing individual thrips in the field is almost impos sible. Therefore, laboratory studies can provide critical information to better understand their population dynamics. The objectives of this study were to compare development and reproductive success oiF. occidentalis and F tritici. To determine immature development time, in dividual adult females were allowed to oviposit for 8 h in 2.5-cm sections of green bean pods con tained in 30-ml clear plastic cups. Then females were removed, and the bean sections were held in an environmental chamber (28.0 ? 1.0?C, 65.0 ? 10.0% r.h., 14:10 L: D photoperiod). Bean sections were observed every 12 h under a stereomicro scope to determine when larvae began to emerge. Then a single newly emerged larva from each fe male was transferred to fresh bean pod section. These individuals were checked every 12 h to de termine when molting occurred. There are 2 ac tive larval stages followed by 2 relatively quies cent non-feeding stages, the propupa and pupa (Moritz 1997). Because data were recorded on an interval scale and composed of different events (molts), survival analyses based on the Wei, Lin and Weissfeld model were used to compare devel opment of the life stages (Li & Lagakos 1997; Wei et al. 1989). In this model, molts were stratified according to their order of occurrence with adult eclosi?n as the terminating event. Because of the stratification, separate hazard ratios can be esti mated for each life stage as well as a comparison of the overall development of the species. Subjects that did not complete development were censored. To determine female adult longevity and fecun dity, newly emerged adult females were placed in dividually in small Petri dishes containing a 2.5 cm piece of green bean, with the ends sealed with Parafilm. Beans were replaced every 24 h, and this process continued for each thrips until death. Beans were subsequently examined over 7 d for l rval emergence. The total number of offspring produced per adult female was recorded. Fecundity was analyzed by repeated measures analysis of co variance, with species as a treatment and longev ity as a covariate. This analysis allowed a compar ison of total fecundity and daily fecundity of thrips. Adult longevity was compared based on survival analysis in which mortality was examined by com paring the Cox proportional hazard for each spe cies (Cox 1972) with ties handled by Breslow's method (Breslow 1974). Insects that were acciden tally lost during the experiment were considered censored observations and not included in fecun dity analyses. Experiments were replicated 3 times with colonies that had been established for 4-8 months from specimens collected in Gadsden County, FL. Voucher specimens are deposited in the collections of the author. All statistical analy s s were performed in SAS ver. 9.1 (SAS 2004). Time to egg hatch was approximately 3 d for both F occidentalis (range 2.5-3.5 d) and F. tritici (range 2.5-3 d). Overall immature development from oviposition to adult eclosi?n was signifi cantly faster for F tritici (median = 11.0 d, range = 9.5-14.0 d, n = 26) than for F. occidentalis (me dian = 12.0 d, range = 9.5-14.5 d, n = 20; %2 = 14.10, df=5,P = 0.015). There were no significant differences between the species in development times of the 2 larval stages (median = 2.0 d, range = 1.0-4.0 d, and 3.0 d, 2-4 d, for first and second stadia, respectively), and the propupal stage (me dian = 1.0 d, range = 0.5-3 d; P > 0.25 for each stage comparison). The difference in total devel opment resulted from the shorter pupal stage of F tritici (median = 2.0 d, range = 1-3 d) compared with/*! occidentalis (median = 3.0 d, range = 2-5 d; X2 = 5.14,df=l,P = 0.02). Adult longevity of females differed between the species, with F occidentalis having a signifi cantly greater longevity than F. tritici (log rank test x2 = 8.2, df=l,P = 0.004). The quartile esti mates of times at which 25%, 50%, and 75% of the individuals had died were all significantly greater for F occidentalis (Fig. 1A) indicating that the greater survivorship of F occidentalis was consis tent throughout the adulthood. Initial survivor ship was high for both species, with less than 10% mortality in the first week after eclosi?n. The maximum longevity was similar for both species,

  • annual cycles of Frankliniella spp thysanoptera thripidae thrips abundance on north florida uncultivated reproductive hosts predicting possible sources of pest outbreaks
    Annals of The Entomological Society of America, 2008

    Abstract:

    Frankliniella spp. (Thysanoptera: Thripidae) thrips damage a variety of crops, feed on a broad range of hosts, and often migrate into cropping systems from adjacent vegetation. To determine potential sources of Frankliniella spp. thrips on crops, annual cycles of abundance of Frankliniella occidentalis (Pergande), Frankliniella fusca (Hinds), Frankliniella bispinosa (Morgan), and Frankliniella tritici (Fitch) were evaluated on seven common, uncultivated reproductive hosts. These hosts included Raphanus raphanistrum L., Rubus trivialis Michx., Rubus cuneifolius Pursh., Vicia sativa L., Trifolium repens L., Solidago canadensis L. and Chenopodium ambrosioides L. Thrips were collected from R. cuneifolius, and T. repens in the spring, R. raphanistrum in the summer, and C. ambrosioides and S. canadensis in the fall. The most common Frankliniella species on every plant species was F. tritici, and a fifth species, Pseudothrips inequalis (Beach), was collected in the fall on C. ambrosioides and S. canadensis. All thrips species were highly aggregated in the flowers or flower racemes, rather than leaves or fruit, and they were generally only collected from flowering plants. R. raphanistrum supported large populations, and they may be an important link for thrips between spring and fall. In addition, it may be an essentially enemy free host, as only one O. insidiosus, an important thrips predator, was collected from this host. S. canadensis also supported large thrips populations in the fall, and it may be a source of thrips migrating into crops the following spring. Controlling thrips on these hosts in their respective seasons may limit the number migrating into cropping systems.

  • differential predation by the generalist predator orius insidiosus on congeneric species of thrips that vary in size and behavior
    Entomologia Experimentalis Et Applicata, 2006
    Co-Authors: Stuart R Reitz, Joe Funderburk, Scot Waring
    Abstract:

    We investigated interactions between the generalist predator Orius insidiosus (Say) (Heteroptera: Anthocoridae) and two species of thrips prey, Frankliniella bispinosa (Morgan) and Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae), and interspecific differences in morphology and behavior between these prey species that could contribute to differences in predation by O. insidiosus . Frankliniella occidentalis is significantly larger than F. bispinosa . Frankliniella bispinosa has greater mobility compared with F. occidentalis . When O. insidiosus was offered either F. bispinosa or F. occidentalis as prey in single species trials, there were no significant differences in the number of prey captured. However, O. insidiosus had significantly more encounters with F. bispinosa than with F. occidentalis . In arenas with equal numbers of both species, O. insidiosus encountered and captured F. occidentalis more than F. bispinosa . In large arenas with two pepper plants ( Capsicum annuum L.), O. insidiosus preyed on more F. occidentalis than on F. bispinosa . These results indicate that O. insidiosus can prey on both thrips species, but that it preferentially captures F. occidentalis . The greater locomotion and movement of F. bispinosa , perhaps combined with its smaller size, allow it to evade predation by O. insidiosus better than F. occidentalis . Consequently, the observed preference of O. insidiosus for F. occidentalis is not exclusively a function of active selection by the predator but also could arise from inherent differences among prey. We propose this differential predation as a mechanism contributing to observed differences in the temporal dynamics of these species in pepper fields.

  • within plant distribution of Frankliniella species thysanoptera thripidae and orius insidiosus heteroptera anthocoridae in field pepper
    Environmental Entomology, 2003

    Abstract:

    Abstract We evaluated the within-plant distribution of Frankliniella spp. and the predator Orius insidiosus (Say) in pepper (Capsicum anuum L.), over a range of field conditions, and we conducted behavioral experiments to examine the time budgets of F. occidentalis (Pergande) and F. tritici (Fitch) females on pepper plant parts. In the field experiments Frankliniella species composition varied by season and location. Still, all populations of thrips and O. insidiosus in untreated and insecticide-treated pepper were highly concentrated in the flowers, with 82–99% of individuals of each taxa found in flowers. This preference for flowers was corroborated by laboratory-choice experiments. Adult females of F. occidentalis and F. tritici showed a strong preference for pepper flowers over leaves and buds. In laboratory observations, females of F. occidentalis spent 3.6× as much time on flowers as on all other plant parts, and females of F. tritici spent over 6.3× as much time on flowers as on all other plant par...

  • Caught efectivenes on sticky trapson Frankliniella occidentalis (Pergande), in greenhouse pepper and weedy areas in La Plata
    2018
    Co-Authors: Carrizo, Paola Irene
    Abstract:

    Se llevaron a cabo estudios sobre eficiencia de captura en trampas adhesivas, sobre Frankliniella occidentalis (Pergande) - tanto en color azul como blanco - en cultivo de pimiento en invernadero y en áreas enmalezadas de los alrededores. La abundancia estacional del trips en el pimiento se estudió mediante el recuento en la planta, y la captura en trampas adhesivas. La distribución espacial en el cultivo fue agregada; y, tanto las formas inmaduras como los adultos, se hallaron predominantemente en las flores. Las trampas de color azul resultaron las más eficientes para la captura total. En las áreas enmalezadas, la hospedera tuvo una influencia mayor que el color de trampa utilizado, y pudo demostrarse que la eficiencia de captura total y por especie no es igual entre el pimiento y las malezas. Si bien las otras especies de trips potencialmente vectores del virus de la peste negra del tomate (TSWV) presentes en la zona: Thrips tabaci Lindemann y Frankliniella schulzei (Trybom) fueron también capturadas, su abundancia relativa fue baja, sobre todo en el cultivo de pimiento, y tuvieron una mayor importancia relativa en las áreas enmalezadas. La correlación entre las capturas en trampas y la abundancia en cultivo para ambos colores fue significativa tanto para las capturas totales de trips como para aquellas considerando a F.occidentalis exclusivamente.Studies about caught efectiveness on western flower thrips Frankliniella occidentalis (Pergande) either on blue and white sticky traps were carried out in greenhouse pepper and weedy areas. Seasonal abundance of these thrips was studied by counting thrips specimens in the flowers - and in the leaves - as well as those collected on sticky blue traps. Into the pepper crop, the spatial distribution was aggregated. The most of specimens collected were accounted in flowers. Total thrips collected on blue traps were higher than on white ones. But the caught efectiveness can be not generalized for different crops: the host species were more important than the color used. Although two other thrips species, Frankliniella schultzei Trybom. and Trips tabaci Lindeman, were present, its abundance in pepper crops was low compared to that of F.occidentalis. Into the weedy areas, they had a larger relative importance than in pepper. These three thrips species were the only vector associated to the tomato spotted wilt virus (TSWV) present at the sampled area. Significant positive correlations were obtained between the number of F.occidentalis collected in pepper flowers and either the number of total trips collected and the number of F.occidentalis collected on blue and white sticky traps.Universidad Nacional de La Plata (UNLP) - Facultad de Ciencias Agrarias y Forestales (FCAF

    Abstract:

    El virus de la peste negra (TSWV) es un Bunyaviridae que causa diferentes síntomas a las plantas, incluso la muerte. En Argentina existen 4 especies de tisanópteros transmisoras: Frankliniella occidentalis, Frankliniella schultzei, Frankliniella gemina y Thrips tabaci. El objetivo del estudio fue conocer las plantas de la vegetación espontánea circundante a los invernaderos de pimiento que actúan como hospedantes verdaderas (de reproducción) de los trips vectores mediante identificación de adultos y de larvas. El estudio se llevó a cabo en tres sitios ubicados en el cinturón hortícola platense (Buenos Aires, Argentina). Durante los años 2000 a 2003 se realizaron relevamientos mensuales en las áreas de los establecimientos en donde no se lleva a cabo el control de las malezas, extrayendo flores de la vegetación espontánea. A través de 60 fechas de muestreo se recolectaron y procesaron 14.636 flores de la vegetación espontánea de las cuales se obtuvieron 54.050 individuos de Thysanoptera, 40.356 adultos (96,96% Thripidae y 3,04% Phlaeothripidae) y 13.694 larvas de primer y segundo estadio (94,1% Thripidae vs. 5,9% Aeolothripidae y Phlaeothripidae). Se registró la presencia de las cuatro especies de trips vectores en el área. La familia botánica no mostró relación con la presencia de trips vectores, ya sea como adulto o larva. De las 40 especies de la vegetación espontánea relevadas resultaron: 19 no hospedantes (NoH), 21 hospedantes de alimentación (HA), 18 hospedantes reproductivos (HR) tanto en sentido amplio (18 sp.) como en sentido estricto (11 sp.) para una, dos, tres o las cuatro especies.The tomato spotted wilt virus (TSWV) is a Bunyaviridae that causes different symptoms to plants, even death. In Argentina, there are 4 thrips species reported as vectors of Tospovirus: Frankliniella occidentalis, Frankliniella schultzei, Frankliniella gemina and Thrips tabaci. The spontaneous vegetation growing within uncontrolled weedy areas near greenhouse peppers were identified as true reproductive hosts of thrips vectors,by means of adult and larval identification. Three sites were studied within the horticultural belt, a strip of 40 km around La Plata City (34°54’ lat. S, 57°55’ long. O), Argentina. During 2000-2003, monthly surveys were performed in the areas of the greenhouses were weed control does not take place, extracting flowers from the spontaneous vegetation. Through 60 sampling dates, 14,636 flowers of spontaneous vegetation were collected, and 54,050 Thysanoptera individuals were obtained, 40,356 were adults (96.96% Thripidae vs. 3.04% Phlaeothripidae) and 13,694 were larvae of 1st and 2nd stage (94.1% Thripidae and 5.9% Aeolothripidae and Phlaeothripidae). The four species seem to have very similar requirements, due the overlap respect to their feeding and breeding hosts. The botanical family was not related to the presence of thrips vectors, neither in adult or larval stage. Out of 40 surveyed weed species, 19 resulted non-host (NoH), 21 feeding host (HA), and the remnant 19, reproductive hosts (HR), (18 in wide sense and 11 in strict sense) for one, two, three or four species of thrips.Fil: Carrizo, Paola Irene.
