Abstract: The abundance of Anopheles arabiensis and its susceptibility to insecticides was studied in New Halfa, eastern Sudan, from March 1999 to June 2000. Of 4854 females anophelines collected, 4847 [99.9%] were An. arabiensis and 7 [0.1%] An. pharoensis. Female An. arabiensis were breeding throughout the year, with 2 peak densities, during the rainy [158.4 females/room/day and 84.7 larvae/10 dips] and irrigated seasons [136.8 females/room/day and 44.8 larvae/10 dips]. The mean biting activity was 28.8 bites/person/ night, found throughout the night, mainly outdoors. Susceptibility of An. arabiensis to insecticides dichloro-diphenyl-trichloroethane [DDT], malathion and fenitrothion was 97.8%, 96.3% and 100% respectively. An. arabiensis is the sole malaria vector in the area and is perennial rather than seasonal
