Table 2 Total and mean (±SE) number of Anopheles gambiae caught in a screen house using a MM-X traps without odour, baited with the Mbita odour blend (MB) augmented with carbon dioxide produced by fermentation of either 250 g refined sugar, 250 g or 500 g molasses by using dry yeast

From: Molasses as a source of carbon dioxide for attracting the malaria mosquitoes Anopheles gambiae and Anopheles funestus

Treatment N Mosquitoes caught
   n Mean (±SE)
No odour 16 25 1.7 ± 0.3a
250 g refined sugar - 17.5 g yeast - 2 L water and Mbita blend 16 465 28.8 ± 1.3b
250 g molasses - 17.5 g yeast - 2 L water and Mbita blend 16 611 37.8 ± 1.5c
500 g molasses - 17.5 g yeast - 2 L water and Mbita blend 16 700 43.4 ± 1.6d
  1. N is the number of experimental nights, n is total number of mosquitoes caught whereas SE is the standard error of the mean catch per night. A total of 200 female An. gambiae were released per night. Mean catches in the same column with different superscript letters differ significantly at P <0.05 (Generalized Linear Models).
