Peristenus howardi Shaw (Hymenoptera: Braconidae) is a parasitoid of Lygus sp. in the Pacific Northwest. Pupation and/or overwintering occurs in the soil adjacent to the host plant. Collections in 2000 conducted in various fields of alfalfa under different tillage regimes indicated there may be some impact on adult emergence due to tillage practices. Emergence cages were erected over plots tilled to different depths arranged in a randomized block design with three treatments replicated four times. The frequency of emergence will indicate weather or not tillage practices impact pupal survival and subsequent adult emergence.
