EVALUATION ON THE ACTIVITY AND EFFICACY OF OMNIPRENE 20CS AGAINST AEDES, ANOPHELES AND CULEX MOSQUITOES IN OUTDOOR MICROCOSMS

Mosquito control by pesticides remains the main intervention to reduce burden of mosquito nuisance and mosquito-borne diseases. In control, larviciding application environmentally friendly larvicides has been one routine operations. Larvicides based on microbial agents insect growth regulators (IGRs) account for most available products. Ones that are formulated using S-methoprene ranged from microencapsulated concentrate (or capsule suspension - CS), various granules, pellets briquets different habitats. The CS formulation among traditional products due its advantages easy application, fast action, even area coverage. current paper evaluated a newly developed OmniPrene 20CSTM containing 20% against mosquitoes public health importance. High inhibition emergence activity was indicated test species, Aedes Anopheles showed higher susceptibility than Culex in laboratory bioassays. performance under field conditions exceeded label specification currently with same pattern. Over 21-day evaluation period, levels 86.4-100%, 89.8-100% 79.8-100% aegypti, hermsi quinquefasciatus respectively when it applied at intended dose 54.8-73.1 mL/ha. This product is expected be used as viable tools along other combat concerns.
