Abstract

The lack of information on identification and distribution of molecular forms of Anopheles gambiae senso stricto (mopti form) and (savanah form) Are one of the major hindrance facing malaria vector control implementation in west Africa. This work focused on identification and distribution of molecular forms of Anopheles gambiae senso stricto (mopti form) and (savanah form). in Ture and Bambam communities of Gombe state. Morphological identified mosquitoes were subjected to PCR analysis to further comfirm the species complex and the molecular form present in the tested sample. The result of this study showed that 25(25%) were Anophele gambiae s.l while 75(75%) did not amplify. From those that amplified, result shows that 25(25%) belongs to Anopheles gambiae s.l. with 11 (22%) and 14 (28%) recorded in Bambam and Ture communities respectively. No other sibling species of An. gambiae complex was recorded. A total of 4(16%) An. Coluzzi [M form], 15(60%) M/S Hybrid molecular forms of An. gambiae s.s. was recorded in both study communities with 6(24%) non-amplified (Fig. 5). No An. gambiae (S form) was recorded in both locations, whereas, 2 An. coluzzi(M form) was recorded in each locations. Fifteen 15 M/S Hybrid form was recorded from both locations with Ture community having 6(40%) while 9(60%) was recorded for Bambam community.
