Abstract
Twenty-two species of insect parasites of Fenusa pusilla (Lepeletier) are listed. Fifteen of these species were reared in the present study from F. pusilla in Quebec, 1 on eggs and 14 on larvae; 4 of them act as both primary and secondary parasites. Of the 15, only 1 has previously been reported as a parasite of F. pusilla. Host–parasite relationship and the degree of parasitism are given for the 15 species reared in Quebec.Thirteen species of predators are listed. Of these, 9, three birds and six insects, were observed feeding on F. pusilla larvae during this study.Keywords
