Abstract: An experimental study was carried out in El geneina town, west Darfur state, Sudan, during the period of October - December 2018. This study aimed to determine the susceptibility status of <em>Ae. aegypti, An. gambiae complex</em> and <em>Culex</em> sp against four insecticide groups (Carbamates, pyrethroids, organophosphate and organochlorine). The immature stages were reared to the adult stage at the insectary unit of integrated vector management and the first-generation progeny (F1) were exposed to WHO insecticide-impregnated papers. The treatments used for the mosquitoes consist of carbamates (0.1% bendiocarb), organophosphates (0.25% pirimiphos-methyl), pyrethroids (0.05% deltamethrin, permethrin 0.75 %) and organochlorines (4% DDT). Ae. aegypti is susceptible to deltamethrin, permethrin and pirimiphos methyl (100%) mortality, whereas highly resistant to DDT 29 % and low resistant to bendiocarb 82%. Moreover, <em>An. gambiae complex</em> is susceptible to organophosphate group 100% mortality and resistant to pyrethroids (deltamethrin 42%, permethrin 83 %) and DDT 79%) table 1. <em>Culex</em> sp resists all insecticide classes except pirimiphos methyl 98%.
