Inter and intra-guild interactions in egg parasitoid species of the soybean stink bug complex

Abstract: -The objective of this research was to evaluate the parasitism behavior of Telenomus podisi Ashmead, Trissolcus basalis (Wollaston) e Trissolcus urichi Crawford (Hymenoptera: Scelionidae) on eggs of Nezara viridula L., Euschistus heros F., Piezodorus guildinii Westwood and Acrosternum aseadum Rolston (Heteroptera: Pentatomidae), in no choice and multiple choice experiments. For all parasitoid species, the results demonstrated the existence of a main host species that maximizes the reproductive success. The com… Show more

“…The parasitoids showed a differential ability to identify and use D. melacanthus eggs as a suitable host, and the proportion of parasitism reported here, for some of the species, showed differences with the parasitism previously reported in other hosts (Pacheco & Corrêa-Ferreira, 1998;Sujii et al, 2002;Laumann et al, 2008). Nevertheless, the present work corroborates previous observations for different species of Scelionidae (Kivan & Kilic, 2002, indicating that, despite being oligophagous or polyphagous (Austin et al, 2005) (Figure 1).…”

“…Outro fator importante ao parasitismo refere-se ao hospedeiro de origem (Sujii et al, 2002). A criação massal de T. pretiosum geralmente é conduzida em ovos de Ephestia kuehniella (Zeller, 1879) (Parra, 1997).…”

“…Euschistus heros (Fabricius, 1791) é o hospedeiro preferencial de Telenomus podisi (Ashmead, 1881), enquanto Nezara viridula (L. 1758) é o de Trissolcus basalis (Wollaston, 1858) (Sujii et al, 2002).…”

“…A preferência de T. podisi por voláteis de soja após a injúria por E. heros pode estar relacionada à preferência de oviposição em ovos de E. heros, em comparação a outras espécies de percevejos (Sujii et al, 2002), e coincide com relatos prévios da resposta deste parasitoide a defesas induzidas em soja após a injúria por E. heros (Moraes et al, 2005(Moraes et al, , 2008. A resposta de T. podisi deu indícios de ser altamente seletiva, já que o parasitoide não respondeu a plantas danificadas por N. viridula ou por E. heros + N. viridula.…”
