    Abstract
    Aim<\/strong>
    The rise in rice production in the district of Malanville, Northen Benin, is a present concern, as it has resulted in the widespread usage of pesticides for crop protection. This could impact human health but also life cycle of Anopheles gambiae<\/em>, the main vector of malaria.
    Methods<\/strong>
    Therefore, insecticide susceptibility bioassays were carried out on populations of An. gambiae s<\/em>.l aged to 3-5 days old (two from areas where insecticide is highly used and other two areas of low insecticide use) and subjected to insecticide-impregnated papers (Permethrin 0.75%; deltamethrin 0.05%; DDT 4% and bendiocarb 0.1%) following WHO protocol. Polymerase Chain Reactions (PCRs) were used for the detection of Acethlylcholinestrase (Ace-1) and the knock down resistance (kdr) L1014F mutations in An. gambiae<\/em> populations. Finally, indirect bioassays were conducted for the investigating on the factors affecting the life cycle of An. gambiae due to the use of pesticides.
    Results<\/strong>
    An. gambiae<\/em> from the four sites were resistant to DDT (6 to 8% and 10 to 14% respectively from areas of high and low dose), pyrethroids (22 to 26% and 30 to 36% for permethrin, from areas of high and low dose respectively and 66 to 70% and 72 to 80% for deltamethrin, from high and low dose) but susceptible to carbamate. The kdr L1014F mutation was detected in An. gambiae<\/em> populations (0.88 to 0.90 and 0.84 to 0.88 from high and low dose, respectively). The ace-1 was detected at low frequencies (<0.002). Bioassays on the impacts of the use of pesticides in the life cycle of An. gambiae<\/em> showed that soil substrates with pesticides residues have a negative impact on the life cycle eggs of An. gambiae.<\/em>
    Conclusion<\/strong>
    These findings confirmed the negative impacts of pesticides use in rice farming and its impacts on the life cycle of An. gambiae.<\/em><\/p>\n\n\n\n
