【 摘 要 】

Ecology of man-biting mosquitoes in Ikeghe Okpatu, Udi L.G.A, Enugu State was studied between August and September 2014. The eggs of mosquitoes were collected using ovitraps. Mosquito larvae were sampled from diverse habitats. Pyrethroid knock-down and human bait techniques were used for collection of indoor and outdoor biting and resting adult mosquitoes respectively. One hundred and sixteen (116) mosquitoes comprising five species were collected as larvae. Culex tigripes 52 (44.8%) and Aedes albopictus 22 (18.9%) formed the bulk of the larval collection. A total of fifty-seven (57) adult mosquitoes comprising four species were collected as outdoor biting mosquitoes. Aedes albopictus 39 (68.4%) constituted the highest percentage of outdoor biting mosquitoes. Twenty-two (22) adult mosquitoes comprising two species: Anopheles gambiae 20 (91.0%) and Culex quinquefasciatus 2 (9.1%) were collected indoors. A total of sixty-five (65) mosquitoes comprising six species were collected using ovitraps: Aedes albopictus 39 (60.0%), Aedes circumluteolus 7 (10.7%), Aedes bromeliad 1 (1.5%), Aedes aegypti 5 (7.6%), Culex quinquefasciatus 12 (18.4%) and Eretmapodite chrysogaster 1 (1.5%) with Aedes albopictus being the highest. The population of mosquitoes encountered in this study is of public health concern. Therefore, extensive vector control is very important in reducing the vector population and is therefore recommended.
