Resumo
aegypti to the action of deltamethrin, (1% concentration), applied in
ultra-low volume, in different schedules in the dose of 0.8 g/Ha were
performed. A LECO equipment attached to the back of a truck was utilized to
apply the deltamethrin. Fifteen biological assays were carried out, with 24
cages, each containing 230 mosquitoes, placed at the house and at
peridomiciliary environment. The mosquitoes were exposed in the "testareas"
for about one hour. Another 36-hour períod of observation followed
the transference of the mosquitoes from their exposition cages to the rest
cages. For each assay, 200 mosquitoes were used as controls, and placed as
far as 2 km from the test área. The dose of 0.8 g/Ha proved to be effícient on
the killing of the Aedes aegypti. Females fed on blood were more resistant to
deltamethrin than fasting ones. Males fed on sugar water were more resistant
than the fasting ones, and these were more susceptible than females. The
statement that only fed females should be used for pesticide susceptibility
testing was confirmed, só these data may be used as guidelines for obtaining
biological assays. The Aedes aegypti was killed more efficiently with
deltamethrin between 12 p.m. and 6 p.m. There was a 0.9% mortality in the control group. The bioassays were carried out with a mean temperature of
27,5 ± 0,4°C, and 66,1 ± 2,5% relatíve air humidíty.
