Abstract
Studies on the infection and infectivity rates of Wuchereria bancrofti in mosquito populations in Makurdi, Nigeria were carried out over a 12 month period in four localities. Adult female mosquitoes (4,320) were morphologically identified and dissected following standard keys and procedures. 1,040 (24.1%) were Anopheles gambiae s.l.; 641 (14.8%) were Anopheles funestus Giles and 2,418 (56.0%) were Culex quinquefasciatus Say while 221 (5.1%) were tagged ‘unidentified’ Anopheles species. The overall microfilarial infection and infectivity rates were 10.1% and 4.8% respectively. The microfilarial infection and infectivity rates differed significantly (ANOVA; χ2 test p
