Abstract

Entomophthora culicis (Braun) Fresenius was found parasitizing adults of Simulium venustum Say and Simulium vittatum Zett. in central Alberta. The first parasitized black fly adults were collected on 17 August 1973 from a moist log on the margin of Flat Creek (113°52′ W. long., 54°41′ N. lat.). In subsequent summers, parasitized black flies were found on various substrates at sites on three other creeks in the area. Parasitized black flies first appeared in late June and were present to mid-September with peak numbers occurring during August. The fungus kills young black fly adults. This is the first record of E. culicis on black flies in Canada.
