The efficiency of this bait was then compared to octenol baited traps.Results: The yeast/sugar(5g: 280g) in 300 m L water generated the highest volume of CO_2. The CO_2 baited traps caught significantly more mosquitoes than octenol baited traps.Conclusions: Yeast-produced CO_2 can effectively replace octenol baits in BG traps.This will significantly reduce costs and allow sustainable mass-application of the CO_2 baited traps in large scale surveillance programs.展开更多
