Effects of ivermectin (MK-933) on the reproductive rate of Aedes aegypti (Diptera: Culicidae).
Aedes aegypti (L.) females were blood fed a single time on rabbits previously injected subcutaneously with ivermectin at 10 or 50 times the labeled dose recommended for cattle (0.2 mg [AI]/kg body weight). Although adult mosquito survival was unchanged by the low dose, fecundity and hatch were depressed slightly. Females fed on rabbits at the high dose exhibited reduced survival and egg production compared with females fed on control rabbits. Eggs from these females also were less likely to hatch, and subsequent larval survival was lower than controls. The effect of ivermectin on these reproductive parameters diminished as the time between drug administration and blood meal increased.
