Extract

Until very recently, knowledge of the feasibility of employing biocontrol against blackflies (Simuliidae) lagged far behind that concerning the prospects for mosquitoes (Culicidae). As recently an the overall review of biological control of vectors by Legner et al. (1974), the only field trial mentioned was an attempt in 1931 to use certain dragon-flies and a predacious chironomid against New Zealand blackflies. Apparently the results of this effort were not followed up. Jenkins's 1964 compilation included two reports of parasitoids (Braconidae, Scelionidae) from European and North American blackflies, yet other species of such entomophaga are known to be important biocontrol agents of certain economically significant arthropods. While neither predators nor parasitoids seem likely to be of practical significance as massproduced and field-liberated blackfly control agents, understanding of the role of such enemies in natural population limitation of Simuliidae (Service & Lyle, 1975) is clearly fundamental to the devising of selective integrated control methodologies that will minimize adverse effects to such already-operating agents.
