ABSTRACT

Accessory gland materials from Spodoptera frugiperda (J. E. Smith) and Heliothis zea (Boddie) (Lepidoptera: Noctuidae) contained kairomones that influenced the host recognition or acceptance behavior of Telenomus remus Nixon (Hymenoptera: Scelonidae) and Trichogramma pretiosurn Riley (Hymeoptera: Trichogrammatidae), respectively. Material from S. frugiperda accessory glands stimulated ovipositor probing and drilling by female T remus but not T pretiosurn. Accessory gland material from H. zea stimulated ovipositor probing and drilling by female T pretiosum but not T remus. An active material for T remus is found in the 700 K protein fraction of accessory gland material from S. frugiperda. The oviposition behavior of the parasitoids is also discussed.
