| Popis: | Malaria is one of water bone-disease and endemic disease in Sudan especially in Gezira state. Insect’s resistance to insecticides becomes one of threats factors in using of insecticides for controlling mosquitoes. This research work aimed to determine the relationship between malaria cases and susceptibility of anopheles arabiensis to six insecticides in Gezira State Central Sudan. About (1250) of anopheles larvae were collected from different sites in the study area, rearing up to adults stages. Susceptibility test conducted using WHO method and bottle bioassay were applied using CDC criteria. Arabiensis were recorded after 10, 15, 20, 30, 50 and 60 min of exposure and percentage mortality after 24 hr for each insecticide were determined. In addition, KDT50 KDT95 were calculated with 95% CL. for DDT 4% (38.0 and 68.5), Deltamethrin 0.5% (27.27 and 53.07), Malathion 5% (12.96 and 36.58), Bendiocarb 0.1% (18.44 and 33.71), Permethrin 0.75% (26.12 and 67.50) and Fenitrothion 1% (44.13 and 122.41). CDC bottle bioassay to insecticide formulation Bendiocarb 80%, Temephos 50%, lambda-cyhalothrin10% and Deltamethrin 25%, percentage mortality were recorded after 10, 15, 20 and 30 min of exposure, also the LT50 and LT95 were calculated with 95% CL. The results revealed that, Anophles arabiensis is tolerant to DDT 4% (93% ± 6.0), although it is susceptible to Deltamethrin 0.05% (100 ±7.6), Malathion 5% (100%±7.6), Bendiocarb 0.1% (100 ±7.6) and Fenitrothion 1% (100 ±7.6), and is only found resistant to Permethrin 0.75% (85%±6.0) according to WHO criteria. The results of CDC Bottle Bioassays concluded that, An Arabiensis found to be susceptible (100% mortality) Bendiocarb 80%, Temphos 50%, lambda-Cyhalothrin 10% and Deltamethrin 25% respectively.
