SUSCEPTIBILITY OF ANOPHELES FLUVIATILIS JAMES TO DIFFERENT INSECTICIDES IN BANDAR ABBAS TOWNSHIP, 2003

: Introduction: An estimated population of 40% of Hormozgan province, southern Iran, live mainly in mountainous areas in close contact with Anopheles Fluviatilis. This specie has highly exophilic and anthropophilic behaviors and is one of major malaria vectors in the mountainous areas of Hormozgan province. This study was conducted to assess the irritability and susceptibility level of An. Fluviatilis to different insecticides. Methods: This cross-sectional study measured susceptibility level of this Anopheles specie to DDT, Dieldrin, Malathion, Fenitrothion, Propoxur, Bendiocarb, Permethrin, Deltamethrin and Cyfluthrin insecticides using recommended diagnostic dose of WHO. Irritability test was carried out by conical chamber exposure method using WHO standard kits to survey the irritability effect of four pyrethroids including, Lambdacyhalothrin, Permethrin, Cyfluthrin and Deltamethrin. The findings were analyzed by analysis of variance and P Results:. The obtained results showed that this specie is susceptible to all tested insecticides and larvicides. The irritability test showed that Permethrin and Deltamethrin were the most and least irritant insecticides, respectively. Conclusion: It seems that all evaluated larvicides and insecticides should undergo laboratory studies before their applications in Anopheles control programs in the area.
