Movements Of Migration And Dispersion Of Adult Spittlebugs [movimentos De Migração E Dispersão De Adultos Da Cigarrinha-das-pastagens]
2015Co-Authors: Sujii E.r., Fontes E.m.g.Abstract:The effect of adults of the spittlebug (Deois flavopicta Stal) movement in their population dynamics was evaluated in pastures of Brachiaria ruziziensis in Brasília, DF, Brazil. Plastic panels containing adesive trap were used to monitorate the movement rates. The data suggest a lack of pattern related to the geographical position of the traps. Vegetation landscapes similar to pastures fields around the study area seemed to favour the dispersion, whilst Cerrados or wood vegetation in the neighborhood inhibted insect dispersion toward this direction and increased return rate of spittlebugs to the pasture. Spittlebugs moved mainly by short, low jumping flights (bellow 1 m). A proportion of 4:1 male:female was captured in the traps, indicating that males move more than females. The movement of marked and recaptured populations was monitored with non-toxic fluorescent powder. Speed rates lower than 5 m/day was observed. Adult dispersion movement, apparently, does not contribute significantly to the loss or recruitment of individuals to populations of D. flavopicta. Consequently, there is no need to consider this movement in modeling this insect population dynamics. Migration may have a role in this dynamics except in some cases, such as outbreaks and local extinction.353471480Begon, M., Harper, J.L., Townsend, C.R., (1996) Ecology: Individuals, Population and Communities. 3.ed., 1068p. , Oxford : BlackwellCarneiro, M.F., Da Cunha, H.F., (1984) Avaliação de Danos e Controle Da Cigarrinha-das- Pastagens (Deois Flavopicta) Na Cultura Do Milho, 14p. , Goiânia : EMGOPA, (EMGOPA.

Predation As A Mortality Factor In Populations Of The Spittlebug, Deois Flavopicta Stål (Homoptera: Cercopidae)
2015Co-Authors: Sujii E.r., Fontes E.m.g., O'neil R.j.Abstract:The spittlebug, Deois flavopicta Stål, is the main pest in cultivated pastures of the "Cerrados" (savanna) in the central region of Brazil. The insect has three discrete generations during the rainy season (September-April) and a synchronized population of diapausing eggs during the dry season (May-August). Experiments in cultivated pastures showed that nonspecific predators were able to affect significantly the mortality rates of diapausing eggs and nymphs of D. flavopicta. Predation was a density independent mortality factor that reduced diapausing eggs by approximately 60% and nymphs by 20% to 47%. The nymph mortality rate due to predation did not differ during the first and the second generations of the year. For the third generation however, the mortality rate was lower, related to a greater degree of nymphal aggregation in spatial refuges. Our direct observations indicate that among the types of predators in pastures, ants potentially make the greatest contribution to mortality, although their impact needs experimental verification. High rates of mortality of eggs and nymphs of D. flavopicta exposed to predators indicate that predation can be an important factor determining the size of adult populations. Therefore, management practices that disturb the predator community may increase the population densities of the spittlebug.314581588Barbosa, F.R., Moreira, W.M., Czepack, C., (1984) Beauveria Bassiana (Bals.)

Effect Of Host Plant On The Fecundity Of Spittlebug Deois Flavopicta Stal (Homoptera: Cercopidae): Implications On Population Dynamics
2015Co-Authors: Sujii E.r., Pires C.s.s., Fontes E.m.g.Abstract:The spittlebug Deois flavopicta Stal (Hom.: Cercopidae) occurs naturally on native grasses in Central Brazil in low population densities. After the introduction of African grasses, mainly of the genus Brachiaria, for cattle raising, D. flavopicta began to produce population outbreaks and became a pest. Two studies were conducted, aiming to estimate the effects of a native and an exotic host plant on the fecundity of this insect. Females of D. flavopicta maintained during the adult stage on Brachiaria ruziziensis produced more eggs and lived longer than those maintained on Axonopus marginatus (a native grass widely distributed in Brazil), independently of the host plant on which the nymphs were reared. Due to the severe damage produced by adult D. flavopicta on the host plant, the effect of insect density on its own reproductive capacity was evaluated in oviposition cages containing plants of B. ruziziensis, standardized in height and stem number. Densities of one, two, three, four and six couples with virgin females were evaluated. Population densities of three couples, equivalent to 150 adults/m2, or higher decreased insect's fecundity. These results contributed to the understanding of the mechanisms that determine low levels of spittlebug populations in the native grasses and promote population outbreaks in introduced ones.304547552Begon, M., Mortimer, M., (1986) Population Ecology: A Unified Study of Animals and Plants. 2nd Ed., , Oxford, Blackwell, 220pBerryman, A.A., The theory and classification of outbreaks (1987) Insect Outbreaks, pp. 3-28. , P.

host specificity of laricobius nigrinus fender coleoptera derodontidae a potential biological control agent of the hemlock woolly adelgid adelges tsugae annand Homoptera adelgidae
Biological Control, 2002Co-Authors: G M G Zilahibalogh, L. T. Kok, S M SalomAbstract:Abstract Host specificity tests of Laricobius nigrinus Fender (Coleoptera: Derodontidae) were conducted under quarantine in Blacksburg, Virginia, to determine the suitability of this beetle as a biological control agent of the hemlock woolly adelgid, Adelges tsugae Annand (Homoptera: Adelgidae), in the eastern United States. Members of the genus Laricobius are known to feed on adelgids. L. nigrinus, native to western North America, was tested on three other adelgids and three non-adelgid species of Homoptera in three families. A. tsugae is an exotic insect pest of eastern (Tsuga canadensis (L.) Carriere) and Carolina (T. caroliniana Engelmann) hemlocks. In paired-choice and no-choice oviposition tests, L. nigrinus females preferred to oviposit in A. tsugae ovisacs over the other test species. Feeding tests showed that L. nigrinus consumed more eggs of A. tsugae than eggs of Adelges piceae (Ratzeburg) and Pineus strobi (Hartig), but not of Adelges abietis (L.). In larval development tests, L. nigrinus only completed development on A. tsugae. These results suggest that L. nigrinus has a narrow host range and that it has potential for biological control of A. tsugae. Based on these results, L. nigrinus has been cleared for field release by USDA APHIS.

hypocrella spp anamorfo aschersonia spp sobre plantas no acre um recurso da biodiversidade para o controle biologico de doencas de plantas
2010Co-Authors: R C Goncalves, M N. De ,lima, M J ThomaziniAbstract:Aschersonia spp., sao patogenos de moscas-brancas (Homoptera e Hemiptera: Aleyrodidae), e de insetos-escama (Homoptera: Coccideae), os quais causam prejuizos economicos diretos e indiretos na agricultura. Ao succionar a seiva das plantas, estes insetos reduzem o vigor das mesmas, induzem clorose, queda de folhas e morte da planta. Alem de introduzir toxinas nas plantas causando a toxicemia, alguns insetos destas ordens apresentam estreita relacao com fitovirus. Ao atuar como reservatorio e vetor de importantes virus de plantas, estes insetos se tornaram pragas de grande importância mundial. Como exemplo, a mosca-branca, Bemisia tabaci biotipo B transmite o virus do mosaico dourado do feijoeiro (BGMV). Dentre as possibilidades de controle de populacoes destes insetos, o controle biologico com microrganismos antagonistas e tema de estudos e pratica em varios paises. No Acre, um projeto realizado pela Embrapa Acre em 2005-2006 objetivou conhecer a diversidade de fungos com potencial antagonista a moscas-brancas que ocorrem em plantios de olericolas, frutiferas, ornamentais e arvores nao frutiferas. Amostras de folhas e ramos de plantas com estromas fungicos foram colhidas e trazidas ao laboratorio para analise em microscopio.

Hypocrella SPP (Anamorfo Aschersonia SPP) sobre plantas no Acre: um recurso da biodiversidade para o controle biológico de doenças de plantas.
In: SEMINÁRIO ANUAL DE COOPERAÇÃO UFAC UF 8. 2010 Rio Branco. Parcerias em pesquisa e ação para a conservação e desenvolvimento sustentável: anais. Ri, 2011Co-Authors: Goncalves R. C., M N. De ,lima, Thomazini M. J.Abstract:Aschersonia spp., são patógenos de moscas-brancas (Homoptera e Hemiptera: Aleyrodidae), e de insetos-escama (Homoptera: Coccideae), os quais causam prejuízos econômicos diretos e indiretos na agricultura. Ao succionar a seiva das plantas, estes insetos reduzem o vigor das mesmas, induzem clorose, queda de folhas e morte da planta. Além de introduzir toxinas nas plantas causando a toxicemia, alguns insetos destas ordens apresentam estreita relação com fitovirus. Ao atuar como reservatório e vetor de importantes vírus de plantas, estes insetos se tornaram pragas de grande importância mundial. Como exemplo, a mosca-branca, Bemisia tabaci biótipo B transmite o vírus do mosaico dourado do feijoeiro (BGMV). Dentre as possibilidades de controle de populações destes insetos, o controle biológico com microrganismos antagonistas é tema de estudos e prática em vários países. No Acre, um projeto realizado pela Embrapa Acre em 2005-2006 objetivou conhecer a diversidade de fungos com potencial antagonista a moscas-brancas que ocorrem em plantios de olericolas, frutíferas, ornamentais e árvores não frutíferas. Amostras de folhas e ramos de plantas com estromas fúngicos foram colhidas e trazidas ao laboratório para análise em microscópio.201
