Abstract: Resistance to insecticides is a limiting factor in the use of insecticides in controlling mosquitoes. This cross-sectional study aimed to monitor insecticide susceptibility of Anopheles arabiensis Patton (Diptera: Culicidae) adults to four commonly used insecticides for indoor residual spraying (deltamethrin 0.05%, bendiocarb 0.1%, DDT 4% and fenitrothion 1%), following WHO protocols. This is one of a series of studies aiming at mapping the resistance of this vector in the Sudan. Two areas (urban and rural) in Ghebeish locality were selected to represent West Kordofan State during the period, July – October 2014. A total of 1,200 females were tested as non-blood-fed using the diagnostic concentrations of the insecticides. The results revealed that the adults were susceptible to bendiocarb 0.1% and fenitrothion 1% in both areas, with mortality rate 100% for bendiocarb, and 100% in rural Ghebeish and 98% in urban Ghebeish for fenitrothion. The adults were also found to be resistant to deltamethrin 0.05% in urban Ghebeish and rural Ghebeish, with 77 and 84% mortalities, respectively. With regard to DDT 4% in the rural Ghebeish 68%mortality was registered, i.e. resistant, and 96% (tolerant) in urban Ghebeish. DDT was not used in the Sudan since 1996.
