Ethyl-methanesulfonate-induced changes in filarial susceptibility in Aedes aegypti (Diptera: Culicidae)
Autor(es): Rodriguez P H
Resumo: The susceptibility to Brugia pahangi infections of F1 progeny derived from female Aedes aegypti treated with ethyl methanesulfonate (EMS) was tested. Three-day-old females were treated with 0.025, 0.050, and 0.075% EMS by allowing them to feed freely for 5 days on sugar cubes containing the chemical. Control and treated females were then mated with normal, untreated males to recover F1 progeny. Percent susceptibility and mean number of infective larvae (Ls) in F1 females were analyzed to test for changes in the fm gene for filarial susceptibility. Sterility was induced in populations exposed to 0.075% EMS. Susceptibility in both the 0.025 and 0.050% EMS F1 populations was reduced by 9 and 20%, respectively. The 0.025% EMS F1 females showed a 35% decrease in mean Ls numbers. At 0.050% EMS, mean Ls numbers decreased by 64%
