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 kdr 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 kdr alleles in An. arabiensis in Sudan emphasizes the need to develop appropriate resistance monitoring and management strategies for An. arabiensis. specialized 052 77 6 1066-1068 2007 0002-9637 https://www.documentation.ird.fr/hor/fdi:010043751 0002-9637 [F B010043751] https://www.documentation.ird.fr/hor/fdi:010043751 https://horizon.documentation.ird.fr/exl-doc/pleins_textes/divers19-11/010043751.pdf IRD - Base Horizon / Pleins textes 2008-05-30 2019-12-16 fdi:010043751 fre
