Abstract

The insect fauna in the mont Saint-Hilaire and mont Saint-Bruno areas of Québec was investigated with Malaise and other traps in 1978, 1979, and 1980 to survey the incidence of potential parasites of the gypsy moth. Fourteen species of known gypsy moth parasites occurring in North America, both indigenous and introduced, were collected. In addition to the species already reported by Madrid and Stewart (1980) the following species that might have host associations with gypsy moth recorded: Exorista mella (Wlk.), Phryxe precosensis Tns., Tachinomyia nigricans Webber, T. variata Curran, Itoplectis conquisitor (Say), and Theronia hilaris (Say), all of which are native to North America. Of hyperparasites of Cotesia melanoscelus (Ratz.) the following additional species were found: Cirrospilus sp., Eupelmella vesicularis (Ratz.), Eurytoma appendigaster (Swed.) and Mesopolobus sp.
