Abstract

Presently, there are over 927 known species or subspecies of sand flies, of which approximately 500 species occur in the New World. This study aimed to collect data and gain knowledge on species structure and distribution of sand fly vectors in Soba and Totti Areas, Khartoum State. This study was conducted in Soba and Tutti Island during (October 2016 - September 2017). Sand flies were collected from the study area mainly using the collection method; sticky paper traps (The STs was used to collect sand flies from indoor, outdoor, domestic and forest sites in the area). The STs made of A4 white papers coated by castor oil on both sites to collect sand flies between 6 pm - 6 am. At outdoor sites, the STs were fixed using wood stick at 5 - 10 cm above the ground level. The collected sand fly samples were labeled and identified according to the standard keys. From a total of 223 sand flies collected, a number of 41 (18.4%) were identified as Phlebotomus papatasi, 64 (28.7%) as Sergentomyia claudia, 96 (43%) as Sergentomyia antanata and 22 (9.9%) were identified as Sergentomyia chowzai in Soba area. Also, from 59 sand flies collected a number of 16 (27.1%) were identified as Phlebotomus papatasi, 4 (6.8%) as Sergentomyia claudia, 19 (32.2%) as S antanata and 20 (33.9%) were identified as Sergentomyia chowzai in Tutti island area. The mean total of sandflies collected in Soba area outdoor was 3.1, indoor (4.4), forest (1.2) and domestic (3.8). While in Tutti island the mean total of sand flies collected at forest were 1.5 and at domestic were 2.7. Soba and Tutti island areas were infested with sand fly species include: Phlebotomus papatasi, Sergentomyia claudia, Sergentomyia antanata and Sergentomyia chowzai. Understanding the requirement of sand flies is very crucial for their breeding habitats in order to control sand flies by treating specific areas, rather than using area-wide applications of pesticides. Knowledge on sandflies habitats and ecological distribution is prerequisite as to specific locations, logic control methods should be implemented, and treatment has to be applied.
