Ocorrência de Ginandromorfismo em Trichogramma pretiosum Riley (Hymenoptera: Trichogrammatidae)
[Occurrence of gynandromorphism in Trichogramma pretiosum Riley (Hymenoptera: Trichogrannnatidae)]
Neotropical Entomology 32 (3), 507-509
Abstract: Egg parasitoids of genus Trichogramma can reproduce by arrhenotokous or thelytokous parthenogenesis. Thelytoky is genetically determined or induced by endosymbionts such as bacteria of the genus Wolbachia. In thelytokous Trichogramma populations, gynandromorphism - an individual having both male and female structures - can occur. Gynandromorphism was observed in one specimen of Trichogramma pretiosum Riley in which the individual presented female genitalia and male antennae, a fact never reported before in Trichogramma in Latin America.
