Parasitism in field populations of the Hessian fly, Mayetiola destructor (Say), from four different north central Texas locations was observed during 1986-1988. Three species of parasitoids attacked the spring generation of the Hessian fly, whereas the fall generations were rarely parasitized. Parasitic activity occurred primarily during the month of May. Parasitism levels ranged from 0 to 87.5% and were affected by time of year, host density, geographic location, and the number of years Hessian flies had been present in an area. HomopoTus destructor (Say) (Hymenoptera: Pteromalidae) was the most abundant parasitoid in Texas, followed by Eupelmus allynii (French) (Hymenoptera: Eupelmidae) and Trichomalopsis subapterus (Forbes) (Hymenoptera: Pteromalidae).
