ABSTRACT A delivery system was developed for releasing Sitotroga cerealella (Olivier) eggs containing the pupae of Qgg parasite wasps, Trichogramma spp., from aircraft for control of tobacco budworm and bollworm, Heliothis spp., in field crops. Two small release units, each con-taining 175-mL egg hoppers, were constructed and posi-tioned at the trailing edge of each wing of a Piper PA-25 aircraft. Application rates of up to 125 X 103 adult parasites/ha are possible when the area coverage rate does not exceed 2.4 ha/min. The delivery system was us-ed to successfully apply parasites to cotton test plots dur-ing two successive growing seasons (1978 and 1979).
