Desempenho de Trichogramma pratissolii Querino & Zucchi (Hymenoptera, Trichogrammatidae) em ovos de Anagasta kuehniella (Zeller) (Lepidoptera, Pyralidae) sob efeito de Bacillus thuringiensis Berliner

Abstract: Visando estudar o efeito da bactéria entomopatogênica Bacillus thuringiensis (Bt) sobre fêmeas adultas de Trichogramma pratissolii e sua progênie, este trabalho foi realizado com diferentes isolados de Bt e Bt kurstaki misturados ao alimento fornecido para o parasitóide antes de parasitar ovos de Anagasta kuehniella. Para tanto, suspensões de seis isolados de Bt E-3, E-10, E-15, E-16, E-19, E-20 e o Bt kurstaki foram misturados em gotícula de mel (1:1), como fonte de alimento e mel puro como testemunha, e, em … Show more

“…Direct effects may occur by ingestion of plant tissues by non-target organisms, whereas indirect effects may occur through multi-trophic interactions (various interrelationships that occur between organisms that are present in the environment) (Craig et al 2008). However, similar to our findings, Pratissoli et al (2006) reported that providing Bt suspensions as a food source to adult Trichogramma pratissoli Querino & Zucchi (Hymenoptera: Trichogrammatidae) had no effect on parasitism, although an indirect effect on offspring emergence was observed with some treatments of different isolates of Bt.…”

Wang et al (2007) also did not observe any difference in offspring longevity, number of parasitized eggs, viability, or sex ratio of Trichogramma ostriniae Pang & Chen (Hymenoptera: Trichogrammatidae) adult females fed with pollen from transgenic and non-transgenic maize.…”

“…Exposure of T. pretiosum to B. thuringiensis-treated eggs did not affect survival. Similar results have been obtained for Trichogramma dendrolimi Matsumura (Takada, Kawamura, & Tanaka, 2001) and Trichogramma pratissolii (Querino & Zucchi) (Pratissoli, Polanczyk, Vianna, Andrade, & Oliveira, 2006).…”
