none Weekly samples of the cutworm, Agrotis ipsilon Rott. larvae were collected for 3 successive seasons 1983/84-1985/86 from 3 Governorates in middle Egypt to survey and evaluate the role of parasitoids in suppressing the pest population. Two gregarious internal larval parasitoids were recorded, Apanteles ruficrus Hal. and Meteorus rubens Nees. (Hymenoptera, Braconidae). Percentages of parasitism were estimated. They reached 20.2, 22.2 and 24.7% in seasons 1983/84, 1984/85 and 1985/86, respectively, with an average of 22.5% (10.3% A. ruficrus and 12.2% M. rubens). The highest rates of parasitism were recorded in March and April.
