Daily and seasonal activities of some sandflies from Surrugia village, Khartoum, Sudan.
The present study is concerned with four species of phlebotomine sandflies prevailing in Khartoum area between the years 1984 and 1987. Flies studied were Phlebotomus papatasi, Sergentomyia antennata, S. clydei and S. schewtzi. The indoor and outdoor daily rhythmic and biting activities were determined during the transmission season for both males and females P. papatasi. Peaks of daily activities and the time at which man is at greatest risk were determined. For each year the monthly relative population densities, populations structure and seasonal changes of sandflies were studied, in comparison with the pooled data of the four years. Seasonal density changes were correlated with temperature, relative humidity and rainfall prevailing in the area.
