Experimental aerial spraying to control mosquitoes was carried out in 1949 and 1950 at several stations of the Royal Canadian Air Force in northern Canada. An account of the work in 1949 has been presented (Twinn, Brown, and Hurtig, 1950). The experiments in 1949 involved the use of a larvicide, followed by a spray against the adults. Further data were required on the degree of effective control that could be obtained by applying one or two sprays against the adult mosquitoes only, in plots of reasonable size. Consequently, in 1950, arrangements were made with the R.C.A.F. to carry out airspray operations against adult mosquitoes at four stations in the Northwest as follows: Fort Nelson, B.C., 24 sq. mi. in two operations, June 6-8 and 19-20; Whitehorse, Y.T., 22 sq. mi. in two operations, June 13-15 and June 30-July 1; Watson Lake, Y.T., 12 sq. mi. June 21-22; and Norman Wells, N.W.T., 8 sq. mi. June 28-29.
