Abstract

A survey of first generation European corn borer (Ostrinia nubilalis) larvae was conducted during 1997 in six cornfields located in northwestern Ohio in order to determine the larval parasitoid complex utilizing this host. Collected larvae were held under constant conditions until the larvae completed development or parasitoids emerged. The following species were recorded: Eriborus terebrans (Hymenoptera: Ichneumonidae), Macrocentrus grandii (Hymenoptera: Braconidae), Sympiesis viridula (Hymenoptera: Eulophidae), and Lixophaga sp. (Diptera: Tachinidae), Levels of parasitism in the different fields ranged from 14.3 to 83.3%. Future research will include surveys of additional fields and sampling of O. nubilalis over the entire season in the northwest Ohio region.
