Table 3 MM-X trap catches (n = 200 released per night) of An. gambiae s.s. (Mbita strain) for 4 trap nights when baited with (A) NH3(0.1, 1, 10 or 100%), (B) CO2(500 ml/min), (C) 1-octen-3-ol, (D) foot odour (FO; from BNN) + NH3(10%), (E) foot odour (FO; from BNN) + CO2(500 ml/min) + NH3. Controls were unbaited traps.
