dc.description.abstractStudies of Anopheles mosquitoes transmitting malaria in some villages of Jigawa State were conducted to establish morpho-species and highliting the members transmitting malaria. A total of 1,863 adult Anopheles were collected, 591 (31.72%) by indoor residual spray collection while 1,272 (68.28%) were reared Anopheles larvae/pupae. Morphological characters and Polymerase Chain Reaction (PCR) were employed in the identification of Anopheles species while Enzyme-linked Immunosorbent Assay (ELISA) was employed to determine their infection by Plasmodium. Morphologically, two species, An. gambiae s.l. and An. funestus were identified, these comprised of 1,362 (73.11%) and 501 (26.89%) respectively. Molecular studies by Polymerase Chain Reaction (PCR) separated An. gambiae s.l. into 1149 (84.36%) An. gambiae s.s and 213 (15.64%) An. arabiensis. Molecular study of An. gambiae s.s. yielded 222 (19.32%) M-form and 927 (80.68%) S-form. The amplification of the 16s rDNA has revealed occurrence of a M/S hybrid in Auyo indoor anopheline population collected. There were 1,373 (73.70%) Anopheles during the rainy season and 490(26.30%) in dry season. The highest population of mosquitoes caught was in September 311 (16.70%). The distribution of Anopheles according to study locations showed that Kirikasamma had the highest 162 (8.70%) mosquito population while Jahun had the lowest 16 (0.85%). Of 591 Anopheles examined by ELISA, 43 (7.28%) were infected with Plasmodium. Of the 43 infected mosquitoes, 10 (23.25%) were An. arabiensis, 5 (11.63%) M-form and 28 (65.12%) S-form. Plasmodium falciparum 32 (74.42%) was more prevalent than P. malariae 11 (25.58%). In conclusion, Anopheles funestus, An. Arabiensis, M-and Sform of Anopheles gambae s.s were the abundant species in the study area. Anopheles mosquitoes were more abundant in rainy season than in dry season. Transmission was more in rainy season than in dry season. Anopheles species M-and S-forms and An. arabiensis were transmitting Plasmodium malariae and P. falciparum.en_US
