Assessment of resistance to DDT and permethrin insecticides and molecular detection of knockdown resistance () alleles were conducted in three populations of from eastern Sudan. Bioassay mortalities ranged from 96.9% to 99.6% for 4% DDT and from 98.4% to 100% for 1% permethrin. The L1014F and L1014S alleles were detected in 25 of 498 mosquitoes. The overall frequencies ranged from 7.0% in the area where insecticide-treated nets were used to 3.0% in the area with agricultural insecticide use. The presence of the alleles in in Sudan emphasizes the need to develop appropriate resistance monitoring and management strategies for .
