Arthropod-borne viruses pose a significant health challenge. Increased prevalence necessitates immediate attention to vector control and resistance management. WHO-approved insecticides to control these mosquitoes include Carbamate, organophosphate and pyrethroid. Adonkolo Campus, Federal University Lokoja metropolis have a disturbing presence of these vectors and therefore the research was aimed to detect the presence of resistance in genus aedes aegypti to those insecticides, DDT (organochloride, dichlorodiphenyltrichloroethane 4%), Bendiocarp (carbamate, 0.1%) and a type ii pyrethroid (Alpha cyhalothrin). The LC99 value was used on larval samples to with the help of probit and compared with the diagnostic value from approved WHO values. Increasing resistance to all three insecticides was obtained with Bendiocarb recording the highest rate at an average of 16 (64%) in all three insecticides while that of DDT stands at an average of 18 (72%) The mortality of less than 90% was declared as resistant. The insecticide susceptibility test for genus aedes. aegypti against these insecticides in Adonkolo showing resistance with a mortality rate at an average of 84% with Bendiocarb recorded the highest of 94%. The results showed that genus aedes aegypti were resistant to all three insecticides used for the WHO Bioassay and the larval test with tempho. Conclusions: The study reveals that the genus aedes aegypti population in the Adonkolo Campus tends to resist exposure to insecticide chemicals approved for vector control by WHO.
