Small plot test of sustained-release Altosid (methoprene) pellets against Aedes taeniorhynchus in brackish water.

Four percent methoprene pellets applied at a rate of 2.2 kg/ha effectively controlled adult Aedes taeniorhynchus emergence (93%) for over 3 weeks. Efficacy declined to 38% 4 weeks posttreatment. At a rate of 4.5 kg/ha, 95% control was maintained for 34 days with the exception of the 5th week when only 72% control was observed.
