Abstract

The efficacy of a new water-based formulation containing 30% permethrin and 30% piperonyl butoxide against laboratory and field populations of Aedes albopictus was evaluated in the laboratory, in semifield experiments, and in residential communities in St. Augustine, FL. In laboratory bottle bioassay, 3 doses (3.18 g/ml, 2.26 g/ml, and 1.59 g/ml) of the permethrin product resulted in 100% mortality of adult mosquitoes in 1 h. In semifield experiments, the insecticide sprayed by the water-based thermal fogger at 381.5 ml/min application rate caused 99% mortality of caged mosquitoes. At 24 h posttreatment in the residential communities, there was 79% and 83% reduction of the natural population (numbers) of adult Ae. albopictus and all adult mosquito species collected in BioGent (BG) sentinel traps baited with a BG lure in the 3 test sites, respectively. There was also a 79% reduction in the number of Ae. albopictus eggs collected in ovitrap used in the treated sites. The reductions were significant for adult Ae. albopictus and all mosquito species at 1 wk posttreatment, but no significant reduction was observed at 2-3 wk posttreatment. These findings demonstrate the effectiveness of the new water-based permethrin product against Ae. albopictus populations in residential communities.
