Impacts of insecticide treated bed nets on Anopheles gambiae s.l. populations in Mbita district and Suba district, Western Kenya.

A widespread insecticidal bed net coverage may replace endophagic species with exophagic species. However, unique local environments also influence a vector population.

Effects of Bacillus thuringiensis israelensis on Anopheles arabiensis.
