Screenhouse mosquito catches in dual-choice test with different odour baits. Estimated mean proportion (GLM) of mosquitoes caught in a screenhouse using MM-X traps with CO2 tested versus an empty trap (A). Cow (B) chicken C) and human (D) emanations were tested in combination with CO2
versus a trap with CO2 alone. Error bars represent the standard error of the mean; ***: χ2-test P < 0.001, NS: χ2-test P > 0.05. Numbers in the bars indicate number of mosquitoes caught.
