Abstract
In 1977, more than 11 000 mosquitoes were collected at Boivin Lake, Granby, and examined for ectoparasitic water mites. Mosquitoes of the genera Aedes, Anopheles, Culex, and Mansonia were parasitized by water mites of the families Hydryphantidae and (or) Arrenuridae. There are 11 new host records presented in this paper. Mosquitoes were found parasitized by two different species of mites on six occasions.
