ABSTRACT
Entomological surveillance is used to determine changes in the geographical distribution and density of vectors, evaluate control programmes, obtain relative measurements of the vectors population over time and facilitate appropriate and timely decisions regarding interventions. This study aimed to present the results of entomological survey conducted in Khartoum State [2002-2005] as part of Khartoum Malaria Free Initiative. It also provides the recent results of the insecticides resistance in the State. Khartoum State has 24 entomological locations which are sited in the different parts of the state. The Data was taken from 3 successive years, from January 2002 to December 2005. All the 24 locations sampled lay within the malaria area in Khartoum State, mosquitoes were collected and processed following WHO guidelines. An.araabiensis was found susceptible to Fenitrothion 1% [100%] and Bendiocarb 0.1% [100%], and possibly resistance to DDT 4% [92.3%], Malathion 5% [83.2%] and permethrin 0 75% [95.1%]. The correlation between the abundances of adult density and larval density were found sign4ficantly in each year [2002 -2005]. Routine surveys for mosquito should be an ongoing function of every mosquito control programme. Entomological surveys aimed to monitor vector density, vector susceptibility to insecticides and to evaluate malaria control programme
