Abstract:
The occurrence of Trichogramma bruni Nagaraja (Hymenoptera: Trichogrammatidae) is described for the first time parasitizing eggs of the velvetbean caterpillar Anticarsia gemmatalis Hübner (Lepidoptera: Erebidae) in Lapa, Paraná, Brazil. This parasitoid was successfully kept in the laboratory on eggs of the velvetbean caterpillar; previously, this species was mainly associated with forest and fruit trees environments, although snap beans and other annual crops were also recorded as hosting lepidopteran eggs parasitized by T. bruni. This is the sixth Trichogramma species recorded parasitizing eggs of A. gemmatalis on soybeans in Brazil.
