Abstract
ABSTRACT. The ability of Telenomus heliothidis Ashmead (Hymenoptera; Scelionidae) to recognize its host, the eggs of Heliothis virescens (F.) (Lepidoptera; Noctuidae), was determined in laboratory studies. The material present in the accessory gland of female H. virescens adults acted as an egg recognition kairomone for T. heliothidis. Host eggs which lacked the kairomone were not attacked, while glass beads the size of H. virescens eggs and coated with the accessory gland material were. The parasitoid failed to respond to the kairomone unless it was associated with a target the size and shape of normal hosts. The kairomone is heat stable, but was deactivated by proteolytic enzymes. The accessory gland contained 200 mg/ml protein which suggests that the kairomone is proteinaceous.
