Abstract
The predators of first- and second-instar larvae of Aedes stimulans and A. trichurus in temporary woodland pools near Belleville, Ontario, were determined mainly by use of mosquito larvae tagged with radioactive phosphorus, but in part from the presence of aedine remains found in the digestive tracts of dissected beetles. Of 428 pond animals collected from the test pools 122 were found to be radioactive above background. Among the 17 species of aquatic insects and other animals that fed on mosquito larvae, 8 species of Dytiscidae, 1 of Hydrophilidae, 1 of Limnephilidae, and 1 pond snail are regarded as important predators. Three additional species of water beetles were identified as predators from aedine remains in their digestive tracts. The abundance of the predators, and the times of occurrence of six species in relation to mosquito development, are discussed.This publication has 1 reference indexed in Scilit:
