Interpretive Summary:

Technical Abstract: Mosquito surveillance in remote areas with limited access to canisters of CO2 or dry ice will benefit from an effective alternative CO2 source, such as the natural production of CO2 from yeast fermentation of several carbohydrate sources. In this study, we document the differences in mosquito and non-mosquito capture rates from CO2 baited (dry ice or yeast fermentation of carbohydrates) CDC traps over 23 trap nights. Results demonstrated the ability of yeast generated CO2 to effectively attract mosquitoes to a CDC trap, regardless of the carbohydrate source. Total collections of mosquitoes using dry ice were significantly different from and had higher capture rates than yeast generated CO2 sources. There was no significant difference between capture rates of mosquitoes using CO2 generated through yeast fermentation between all three carbohydrate sources. Species comparison and composition will be discussed between carbohydrate sources and dry ice. Volatiles produced by yeast fermentation were also documented by carbohydrate source, and will be discussed regarding synergistic effects with CO2 on mosquito collections.
