A trial test of 5AIGRNG micro-encapsulated inesfly paint on Aedes mosquitoes in selected communities of Nasarawa State, Nigeria was determined. Aedes, capable of transmitting deadly infection and afflicted population, posing one of the greatest threats in the history of humanity, and a serious public health concern. Major outbreaks of dengue, yellow fever is rising at alarming rate in Nigeria. WHO cone bio-assay as a testing protocol for bio-efficacy assay with mosquitoes was used for a time-mortality on Aedes mosquitoes. The wall cone bio-assay were mounted at variance, the painted plaster wall was measured at 0.5m, 1.0m, 1.5m height and from the rain water puddles at 30 minutes, Ae aegypti showed resistance in cone 1 and 2 mean percentage variance (70%resistance and 80%resistance), but 98%susceptible susceptibility was observed in cone 3 and at 24hrs post exposure, 100%susceptible susceptibility was met. From West lands, tree holes, water storage containers, and tires, were equally resistance in cone 1, 2, and 3. And at 30m, septic tanks, gutters and drains were 100%susceptible susceptible at 1hr and 24hrs respectively. For Ae albopictus at 30m, 70%resistance knockdown was recorded and 80%resistance at 1hr interval, and a knockdown-make up to 100% susceptible at 24hrs post-exposure of the emulsified inesfly micro-encapsulated product across all sites of larval collection. Rainwater puddles, and west lands at 0.5m height were resistance while from the tree holes 98%susceptible was susceptible at 1hr, water storage containers, tires, septic tanks, gutters and drains were in any case resistance in all the three trial test of the cone bio-assay at 30m, and 1hr respectively. This new product should fast be adopted enough to delay the emergence of insecticide resistance, and should prompt if possible more decision from WHO recommendation of 5AIGRNG micro-encapsulated inesfly insecticide paint for a widespread use against Aedes species in Nigeria.
