Abstract

Abstract: Aedes aegypti were exposed to water treated with mosquitocidal chips containing the insecticide pyriproxyfen in a polymer formulation. Chips were tested under different conditions; different water volumes, in containers made of different material, and in water with different levels of organic matter. Treated chips caused 100% mortality of Ae. aegypti during their pupal stage independent of conditions chips were exposed to in water. When tested for longevity, the chips containing 840 µg of pyriproxyfen killed 100% of Ae. aegypti for 4 sequential months of the chips being reused in water. Chips containing 8.4 µg of pyriproxyfen ceased to work after the first week of treatment. When mosquitocidal chips were used in > 25% of the oviposition containers within their cages, there was a significant control of the mosquito populations. Mosquitocidal chips worked in different environments, lasted for extended periods of time, caused significant mosquito population decreases, and were effective in controlling Ae. Aegypti.
