Abstract
Studies on species composition and significance of Insecticide Treated mosquito Nets (ITNs) for malaria vector control were conducted in four randomly selected localities in Jolie Peasant Association, Meskan Woreda, Guragie Zone, Southern Ethiopia. Larval and adult collections were carried out, from different sites throughout the study period to identify species composition, thus three Anopheline species: Anopheles gambiae s.l., Anopheles pharoensis and Anopheles christyi were identified. An. gambiae s.l. was the principal vector responsible for the transmission of malaria in the study area. The main identified breeding sites in the study area includes rain pools, river pockets, ponds, marshes and pools of water from spillage of canals which are the result of human activities rather than environmental causes. To investigate the effect of Insecticide (Permethrin) Treated Mosquito Nets (ITNs), 20 houses with and without ITNs were paired. Malaria incidence, resting density and parity rate were assessed. The result of malaria incidence showed that the difference was not significant at (2 = 0.6247, P > 0.05). However, a clear reduction in the density of indoor resting population of An. gambiae s.l. were found in houses with ITNs (t = 10.0278, df = 38, p < 0.05). Similarly, the parous rates were significant at (2 = 4.657, p < 0.05). Further entomological studies are required to determine the vectorial status of the Anophelines in this area. Besides, in providing an enabling environment for scaling-up actions, governmental sectors need to focus on creating awareness on utilization and demand for ITNs through health information channels and mass media.
