Information is provided on 15 hymenopterous and 5 dipterous parasitoids of Pseudaletia unipuncta [Mythimna unipuncta] reared from larvae and pupae collected at various localities in Quebec during 3 outbreaks in 1977-84. Ichneumon deliratorius cinctitarsis, Itoplectis conquisitor and Therion circumflexum (from pupae) and Trichogramma minutum (from eggs) are new host records. Estimates of the incidence of parasitism and the structure of the parasitoid guild were influenced by the presence of pathogens in host populations.
