Abstract
The program of biological studies and experiments in chemical control of mosquitoes at Churchill, Manitoba, in 1947 and 1948 (Twinn et al., 1948; Twinn, 1950) was extended in 1949 to include Goose Bay, Lahrador. The program at Goose Bay was primarily designed to develop control measures for the northern species of biting flies. since the control experiments were scheduled for definite periods during the summer in 1949 (Twinn et al., 1950), limited biological studies were carried on as circumstances permitted. These field studies produced information on the species of mosquitoes present and their development and ecology. Data obtained in 1949 from field observations, collections, identifications of adult and immature forms. and limited laboratory rearings are summarized in this paper. Additional data obtained by officers of the Division of Entomology in 1950 under similar circumstances have been included, in some cases as confirmation of observations in 1949.
