Abstract

The distribution and abundance of malaria vectors depend on biotic and abiotic factors. A monthly longitudinal study was undertaken in the study area from October to December 2016 and from March to April 2017 to determine the distribution and abundance of larval malaria vectors. Malaria vectors were collected from three villages by standard dippers and reared into adult stages under laboratory within favorite environmental conditions. Anopheles species were identified based on morphological features using standard keys. The data were analyzed using SPSS software. A total of 481 malaria vectors were collected. The malaria vectors in the study area comprise three species – An. gambiae s.l, An. funestus s.l, and An. pharoensis. Out of those malaria vectors species, An. gambiae s.l was the most abundant which accounts 45.11 % followed by An. phronesis and An. funestus s.l with abundances of 33.68 % and 21.21 % respectively. The highest abundance of An. gambiae s.l and An. pharoensis were recorded in October and November 2016, but An. funestus s.l was more abundant in March and April 2017. The result indicated that the study villages are at risk of mosquito-borne diseases including malaria. So mosquito control measures targeting both the mosquito immature and adults to reduce the problem of mosquito-borne diseases in the study area.
