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.
本研究关注1984年至1987年间在喀土穆地区常见的四种白蛉。所研究的白蛉为巴氏白蛉、触角司蛉、克莱德司蛉和施氏司蛉。在传播季节期间，确定了巴氏白蛉雌雄成虫的室内外昼夜节律和叮咬活动。确定了每日活动高峰以及人类面临最大风险的时间。对每年白蛉的月相对种群密度、种群结构和季节变化进行了研究，并与四年的汇总数据进行了比较。季节性密度变化与该地区当时的温度、相对湿度和降雨量相关。
