Hymenopteran Parasitoids and Dipteran Predators Found Using Soybean Aphid After Its Midwestern United States Invasion

Abstract

Parasitoids and predatory ies that can attack soybean aphid, Aphis glycines Matsumura (Hemiptera: Aphididae), in soybean, Glycine max (L.) Merr., elds were identied 3 to 4 yr after the aphid was rst sighted in the north central United States. We detected 15 species by exposing soybean aphid to ovipositing parasitoids and predatory ies at two locations in southern Michigan. The species detected were (in order of the number of specimens recovered from high to low) Aphidoletes aphidimyza Rondani (Diptera: Cecidomyiidae), Lysiphlebus testaceipes Cresson (Hymenoptera:
