From: Development of a chimeric odour blend for attracting gravid malaria vectors
Assessment of the chimeric odour blend under field conditions. In Meki, Anopheles arabiensis (A) and An. pharoensis (B) were caught using CDC traps hung either low (CDC-L) or high (CDC-H) and BG-Sentinel traps, with (BG-W) and without water (BG). Traps were baited with a solvent control (C) or different doses of the chimeric blend. Control traps set indoors and outdoors at a nearby site demonstrated a low population density of both An. arabiensis (C) and An. pharoensis (D) in the area, with CDC traps catching more Anopheles mosquitoes outdoors near the houses. In Sile, Suna traps, set next to houses, baited with the chimeric blend (3 ng µl−1) caught a significantly higher number of An. arabiensis than unbaited traps (E)
