Abstract

Mosquito-borne diseases are becoming a serious global burden. The objective of the study purposed to determine anopheline mosquito fauna in Elgenaina locality, West Darfur State. Across-sectional entomological surveys were run during April 2016 to March 2017 to determine some aspect on ecology of anopheline mosquitoes in Elgenaina locality, West Darfur State. Randomly selection of the stations was conducted, larval habitats were surveyed, fully described, and hence density of anopheline larval in each habitat was recorded using standard dipping method (WHO, 1992). Larvae from these habitats were also being sampled, preserved in 70% ethanol in appendorff tubes for species identification. In addition, larvae were taken to the insectary and reared to adult for species identification. The results showed that, from 667 larvae collected; a number of 260 larvae were identified (39%). From 260 identified a number of 244 were identified as An. arabiensis (93.8%), 17 (6.5%) were An. rufipse and 1 (0.4%) were An. phareoensis. The mean total of water pipe leakage was significantly greater in rainy season (25.9) compared to dry season (10.4). The high mean total of swamp was significantly increased in rainy season (55.3) compared to 17.8 in dry season. The mean total of early instar mosquito larvae was significantly greater in rainy season compared to dry season. In addition, late instar mosquito larvae was significantly greater in rainy season versus dry season. It was clear that, An. arabiensis was the common Anopheles species found in the different sentinel sites of Elgenaina City, West Darfur State followed by An. rufipse and An. phareoensis. This study recommends applying of larval source management during dry season to reduced habitats of anopheline larvae. In addition to maintenance of leakage water pipes or modernization of water net lines.
