摘　　要：Objectives: To evaluates carbon dioxide(CO_2) production from yeast/sugar mixtures and its efficiency as an attractant in BG-Sentinel traps.Methods: The rate of CO_2 production was optimized for different yeast/sugar mixtures.The optimized mixture was then used as bait in BG-Sentinel traps. 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.Objectives: To evaluates carbon dioxide (CO2) production from yeast/sugar mixtures and its efficiency as an attractant in BG-Sentinel traps.

Conclusions: Yeast-produced CO2can effectively replace octenol baits in BG traps. This will significantly reduce costs and allow sustainable mass-application of the CO2 baited traps in large scale surveillance programs.
