title: Selection of oviposition sites by female Aedes aegypti exposed to two larvicides.
abstract: The selection of oviposition sites by female mosquitoes involves the ability to choose less dangerous larval habitats. The aim of the present study was to evaluate the ovipositional behavior of female Aedes aegypti in selecting sites treated with 2 different larvicides. The study was conducted in metal cages with plastic cups containing paper strips and either spinosad or temephos, or dechlorinated water (control). After exposing all treated and control cups to ovipositing female mosquitoes for 3 days, the paper strips were removed and examined for egg laying. Based on the number of eggs laid per treatment, the oviposition index was found positive for spinosad (0.66) but negative for temephos (-0.49), indicating that the natural product spinosad acted as an attractant and temephos as a repellent.
