Abstract

Seasonal abundance of a pupal parasitoid Diapetimorpha introita (Cresson) (Hymenoptera: Ichneumonidae) and the beet armyworm Spodoptera exigua (Hübner) (Lepidoptera: Noctuidae) was monitored with pheromone-traps. D. introita males were caught in wing traps baited with live females, and beet armyworm males were caught in bucket traps baited with synthetic pheromone. The greatest number of D. introita adult males was caught during early autumn, approximately one month after the greatest number of beet armyworm males was caught, and represents the most convenient time during which to conduct trapping experiments.
