Previous results from laboratory and prefield assays obtained by CIPEIN indicated that the fumigant canister CIPEIN PF-7, a smoke generating formulation containing 5% beta-cypermethrin, has an excellent adulticide performance for Aedes aegypti (L.) control.       A field trial was performed to evaluate the effectivity of CIPEIN PF-7 to control adult mosquitoes of Aedes Aegypti inside the houses.       The trial was done in Colonia Delicia, a locality of 4750 inhabitants, located in Misiones, a subtropical area in the NE of Argentina, an area highly infected with the vector and in risk of Dengue.       One fumigant canister was applied in each house, which remained closed during 1 hr and then the fumes aired at least during 15 min. Taking into account the time spent in the fumigation activities, the rate of the treatment was around 20 houses per worker per day. Cages with adult mosquitoes and plastic vessels with water containing mosquitoes larvae were put in different places of the house, obtaining 100% mortality in each case after treatment with the fumigant canister. The residual effect showed 100% mortality of adults exposed 2 hr at least 3 days after treatment and 100% mortality of larvae 1 day after treatment.
