  • uncovering cryptic parasitoid diversity in horismenus chalcidoidea Eulophidae
    PLOS ONE, 2015
    Co-Authors: Sarah G Kenyon, Christer Hansson, Sven Buerki, Nadir Alvarez, Betty Benrey
    Abstract:

    Horismenus parasitoids are an abundant and understudied group of eulophid wasps found mainly in the New World. Recent surveys based on morphological analyses in Costa Rica have quadrupled the number of named taxa, with more than 400 species described so far. This recent revision suggests that there is still a vast number of unknown species to be identified. As Horismenus wasps have been widely described as parasitoids of insect pests associated with crop plants, it is of high importance to properly establish the extant diversity of the genus, in order to provide biological control practitioners with an exhaustive catalog of putative control agents. In this study, we first collected Horismenus wasps from wild Phaseolus bean seeds in Central Mexico and Arizona to assess the genetic relatedness of three morphologically distinct species with overlapping host and geographical ranges. Sequence data from two nuclear and two mitochondrial gene regions uncovered three cryptic species within each of the three focal species (i.e., H. missouriensis, H. depressus and H. butcheri). The monophyly of each cryptic group is statistically supported (except in two of them represented by one single tip in which monophyly cannot be tested). The phylogenetic reconstruction is discussed with respect to differences between gene regions as well as likely reasons for the differences in variability between species.

  • emergence of palmistichus elaeisis hymenoptera Eulophidae from pupae of thagona tibialis lepidoptera lymantriidae collected in the medicinal plant terminalia catappa combretaceae
    Entomological News, 2012
    Co-Authors: Wagner De Souza Tavares, Teresinha Vinha Zanuncio, Christer Hansson, Jose Eduardo Serrao, José Cola Zanuncio
    Abstract:

    ABSTRACT: The biological control of pests is an alternative to chemical control in plant crops used in folk medicine. The bark and the roots of tropical almond Terminalia catappa L. (Combretaceae) are indicated for dysentery, bile and gastric fevers and intestinal parasites; the leaves are used to treat colic and hemorrhoids; the unripe fruit is an astringent, the ripe fruit is a laxative, and its oil is used as an emulsifier for soothing the chest. Palmistichus spp. (Hymenoptera: Eulophidae), gregarious endoparasitoids, were little known until the publication of the first revision of this group in 1993. Fifty-four individuals of Palmistichus elaeisis Delvare and LaSalle, 1993 (Hymenoptera: Eulophidae) were collected after emerging from a pupa of Thagona tibialis Walker, 1855 (Lepidoptera: Lymantriidae) when their caterpillars defoliated a tree of T. catappa at the campus of the Federal University of Vicosa (UFV) in Vicosa, Minas Gerais State, Brazil. The parasitoid individuals were identified by the Depa...

  • combined molecular and morphological phylogeny of Eulophidae hymenoptera chalcidoidea with focus on the subfamily entedoninae
    Cladistics, 2011
    Co-Authors: Roger A Burks, John M Heraty, Marco Gebiola, Christer Hansson
    Abstract:

    A new combined molecular and morphological phylogeny of the Eulophidae is presented with special reference to the subfamily Entedoninae. We examined 28S D2–D5 and CO1 gene regions with parsimony and partitioned Bayesian analyses, and examined the impact of a small set of historically recognized morphological characters on combined analyses. Eulophidae was strongly supported as monophyletic only after exclusion of the enigmatic genus Trisecodes. The subfamilies Eulophinae, Entiinae (=Euderinae) and Tetrastichinae were consistently supported as monophyletic, but Entedoninae was monophyletic only in combined analyses. Six contiguous bases in the 3e′ subregion of the 28S D2 rDNA contributed to placement of nominal subgenus of Closterocerus outside Entedoninae. In all cases, Euderomphalini was excluded from Entiinae, and we suggest that it be retained in Entedoninae. Opheliminae n. stat. is raised from tribe to subfamily status. Trisecodes is removed from Entedoninae but retained as incertae sedis in Eulophidae until its family placement can be determined new placement. The genera Neochrysocharisstat. rev. and Asecodesstat. rev. are removed from synonymy with Closterocerus because strong molecular differences corroborate their morphological differences. Closterocerus (Achrysocharis) germanicus is transferred to the genus Chrysonotomyian. comb. based on molecular and morphological characters.

  • cornugon hymenoptera Eulophidae entedoninae a new genus from tropical america including ten new species
    Zootaxa, 2011
    Co-Authors: Christer Hansson
    Abstract:

    Cornugon gen. nov. (Hymenoptera: Eulophidae: Entedoninae) is described from the Neotropical region, including ten new species from Costa Rica, Ecuador, Honduras and Mexico: C. albicoxa, C. anais, C. bicornis, C. diabolos, C. diceros, C. gibberum, C. leios, C. petiolatum, C. reticulatum, and C. unicornis spp. nov. The monophyly of the genus is demonstrated through two putative morphological autapomorphies. One of the autapomorphies is in a recently discovered character system, wing interference colour patterns (WIPs). WIPs are used here for the first time at the generic level for the classification of insects. Cornugon is compared to Pediobius Walker with which it shares the most apomorphies.

    Abstract:

    The blue gum chalcid, Leptocybe invasa Fisher & La Salle (Hymenoptera: Eulophidae), native from Australia, can severely damage eucalyptus (Myrtaceae) plants. This insect was found on Eucalyptus grandis seedlings in May 2015, in Treze de Maio municipality in Santa Catarina state, Brazil

  • Longevity and survival of Leptocybe invasa (Hymenoptera: Eulophidae), an invasive gall inducer on Eucalyptus, with different diets and temperatures
    PeerJ Inc., 2018
    Co-Authors: Amanda Rodrigues De Souza, Leonardo Rodrigues Barbosa, José Cola Zanuncio, José Raimundo De Souza Passos, Bárbara Monteiro De Castro E Castro, Carlos Frederico Wilcken
    Abstract:

    The blue gum chalcid, Leptocybe invasa Fisher & LaSalle (Hymenoptera: Eulophidae), causes galls on Eucalyptus spp. leaf midribs, petioles and stems. Biological aspects need to be studied to assist in developing management strategies and to maintain this insect in the laboratory to rear the parasitoid Selitrichodes neseri Kelly & La Salle (Hymenoptera: Eulophidae) that depends on having a supply of Eucalyptus seedlings infested by L. invasa. We evaluated the longevity and survival of L. invasa individual non reproductive females fed with six different diets (pure honey, 50% honey solution, pure honey plus eucalyptus leaves, eucalyptus leaves, distilled water, or no food) and seven different temperatures (10, 14, 18, 22, 26, 30 and 34 °C). Leptocybe invasa fed with 50% honey solution and reared at 14 or 18 °C showed the greatest longevity and survival

  • antennal sensilla and sexual dimorphism of the parasitoid trichospilus pupivorus hymenoptera Eulophidae
    Microscopy and Microanalysis, 2016
    Co-Authors: Isabel Silva, José Cola Zanuncio, Kleber De Sousa Pereira, Thomas Spranghers, Jose Eduardo Serrao
    Abstract:

    Sensory structures (sensilla) of insects are present in high number in the antennae are important for perceiving environmental cues. Thus, sensilla play an important role in the localization, discrimination, and acceptance of a possible host by parasitoid insects. The sensilla, classified according to their shape, size, and distribution, may also show sexual dimorphism in insects. The types and distribution of antennal sensilla in female and male parasitoid Trichospilus pupivorus (Ferriere, 1930) (Hymenoptera: Eulophidae) were evaluated. T. pupivorus females had longer antennae than males. Both males and females have ten sensilla types with higher abundance of placoid sensilla in females, which suggest a possible functional dimorphism.

  • reproductive and toxicological impacts of herbicides used in eucalyptus culture in brazil on the parasitoid palmistichus elaeisis hymenoptera Eulophidae
    Weed Research, 2012
    Co-Authors: Claubert Wagner Guimaraes De Menezes, Marcus Alvarenga Soares, Jose Barbosa Dos Santos, S L Assis, Arley Jose Fonseca, José Cola Zanuncio
    Abstract:

    Menezes CWG, Soares MA, Santos JB, Assis Junior SL, Fonseca AJ & Zanuncio JC (2012). Reproductive and toxicological impacts of herbicides used in Eucalyptus culture in Brazil on the parasitoid Palmistichus elaeisis (Hymenoptera: Eulophidae). Weed Research52, 520–525. Summary The expansion of eucalyptus tree plantations in Brazil has raised concerns that the use of herbicides may reach non-target organisms and compromise the environment where parasitoids are used to control Lepidoptera defoliators. So, the effect of herbicides used in eucalyptus crops on the parasitoid Palmistichus elaeisis Delvare and LaSalle, 1993 (Hymenoptera: Eulophidae) was evaluated in terms of the impact on reproduction and survival. Treatments consisted of commercial doses of the herbicides sulfentrazone, oxyfluorfen, glyphosate and isoxaflutole with a water-only control. The herbicides were sprayed on the pupae of the alternative host Tenebrio molitor Linnaeus (Coleoptera: Tenebrionidae), which were exposed to parasitism by six females of P. elaeisis per pupa. Glufosinate and oxyfluorfen reduced parasitism and emergence of this parasitoid and were considered more harmful to the P. elaeisis females. Glyphosate and isoxaflutole resulted in higher numbers of individuals and females produced per female; thus these herbicides were less harmful to P. elaeisis and maybe used in IPM programmes in eucalyptus plantations.

  • phylogeny of Eulophidae hymenoptera chalcidoidea with a reclassification of eulophinae and the recognition that elasmidae are derived eulophids
    Systematic Entomology, 2000
    Co-Authors: N Gauthier, J Lasalle, Donald L J Quicke, H C J Godfray
    Abstract:

    Summary Eulophidae is a large and biologically varied family of parasitoid wasps, traditionally split into four subfamilies; Elasmidae is a uniform (single genus) and morphologically distinct family of wasps that are thought to be related to Eulophidae. The D2 region of the 28S rDNA gene (≈ 560 bp) of eighty-seven species of eulophid, three species of elasmid and sixteen outgroup species in five families was sequenced. Cladograms were constructed, and the results compared with conclusions drawn from morphological studies. The gene was most informative at the level of subfamily and tribe. The monophyly of both Eulophinae and Tetrastichinae is supported; that of Entedoninae and Euderinae is less clear. Results indicate that Eulophinae is a derived group within Eulophidae, rather than an ancestral group as previously thought, and that Elasmus, the sole genus of Elasmidae, belongs within this subfamily. The tribes of Eulophinae are reassessed and only three accepted: Eulophini (including Euplectrini and Elachertini), Elasmini and Cirrospilini LaSalle trib.n. for Boucek's Ophelimini with Ophelimus and Australsecodes excluded. Three small Australian tribes, Anselmellini, Ophelimini and Platytetracampini, are removed from Eulophinae and Entedoninae, respectively, but their exact relationships and subfamily status cannot as yet be decided. Another tribe, Keryini, known from a single Australian genus, is excluded from both Eulophinae and Eulophidae.

  • first report of the eucalyptus gall wasp ophelimus maskelli hymenoptera Eulophidae an invasive pest on eucalyptus from the western hemisphere
    Zootaxa, 2015
    Co-Authors: Roger A Burks, Jason L Mottern, Rebeccah A Waterworth, Timothy D Paine
    Abstract:

    Ophelimus maskelli (Ashmead) (Hymenoptera: Eulophidae) was found in southern California, USA, on March 17, 2014, in Riverside County, University of California Riverside Campus (UCR), and has been common there since then. It has also been found in other locations in southern California, including San Diego County (San Diego Safari Park on November 1, 2014), and Orange County (Laguna Niguel Regional Park). Specimens collected from UCR were compared with voucher specimens of O. maskelli collected from Lazio, Italy, and were found to be conspecific. This represents the first report of O. maskelli from the Western Hemisphere.
