Abstract

In 1976 and 1977, adults of Aedes sticticus (Meigen) and Aedes vexans (Meigen), marked with fluorescent dust, were captured in light traps up to 33 days after release and at distances up to 11 km from the release site. Adults flew primarily northwest from the release sites, and with the prevailing winds. Porcine and bovine hosts present at some of the trapping sites, appeared to be highly attractive to female mosquitoes. Within an 8 km trapping radius of the release site, the mean number of marked/trapped female mosquitoes decreased with distance. In 1977, 50% of the marked captures (weighted according to km2 of trapping area) were taken within the first 2 km, 82% within 4 km, 92% within 6 km, and the remainder out to 8 km from the release site. For all trap sites, the mean recovery of marked/unmarked adults over a 33 day trapping period in 1977 was 1:1113.
