Description: Abstracts: Percent parasitism by Glypta fumiferanae Viereck decreased significantly in the sprayed areas following application, while Phytodietus fumiferanae Rohwer parasitism increased in the same areas. Apanteles fumiferanae Viereck increased significantly in two of the sprayed areas the first year after spraying, but percent parasitism generally followed similar patterns in treated and untreated areas. Ceromasia auricaudata Townsend decreased significantly in the sprayed areas the first year after spraying, but 2 years after spraying percent parasitism by this species was about equal in both sprayed and unsprayed areas. Other insect parasite exhibited similar trends in sprayed and unsprayed areas during the 2 years following spraying, or their numbers were too meagre to determine a trend.
