Abstract

This study evaluated the efficacy of Mosquilarv containing 0.4% S-methoprene in reducing population densities of Aedes spp.Oviposition traps treated with 1.5 mg Mosquilarv granules containing 0.4% Smethoprene and untreated controls were placed in houses where natural breeding sites of Aedes spp.are often found traps were collected 7 days later, eggs were counted and kept under rearing conditions until complete emergence of larvae in control traps and death or emergence of larvae in traps treated with 0.4% Mosquilarv.Our results show a predominance of the Aedes vector species collected in Porto-Novo and Ifangni.Ae. aegypti and Ae.albopictus share the same ovitraps.The results revealed a considerable reduction in emergence in treated ovitraps, ranging from 64.42% to 93.53%.Mosquilarv with 0.4% Smethoprene showed interesting results in reducing the density of Aedes spp vectors and could be considered as a response and prevention tool for possible dengue epidemics in Benin.
