Abstract: Anopheles mosquito’s resistance to insecticides has been one of the major challenges in eradicating malaria. This study was carried out to determine the susceptibility status of Anopheles mosquitoes to Deltamethrin and Bendiocarb in some communities of Nasarawa Local Government Area of Nasarawa State for four months. The research was carried out at the insectary laboratory of Nasarawa State University Keffi. Center for Disease Control (CDC) bioassay bottle and WHO impregnated papers were used to test the susceptibility of Anopheles mosquitoes. The result shows that Anopheles mosquitoes exposed to Bendiocarb and Deltamethrin using CDC bioassay bottles were susceptible at 15mins, there was no mortality recorded from the control at 30 minutes of exposure. Anopheles mosquitoes exposed to WHO impregnated paper of Bendiocarb and Deltamethrin were susceptible at 60 minutes, mortality was recorded at 24h post exposure time from the control. χ2analysis of Bendiocarb and Deltamethrin insecticides exposed to CDC bioassay bottles was statistically insignificant p>0.05, while χ2 analysis of Bendiocarb and Deltamethrin exposed to WHO impregnated papers was also insignificant p>0.05. These results indicated susceptibility of Anopheles mosquitoes to Bendiocarb and Deltamethrin for the two methods of susceptibility test. The use of these synthetic insecticides in the control of malaria should be encouraged and made available.
