title: Comparison of Volatiles and Mosquito Capture Efficacy For Three Carbohydrate Sources In A Yeast-Fermentation CO2Generator.
abstract: Mosquito surveillance in remote areas with limited access to canisters of CO2or dry ice will benefit from an effective alternative CO2source, such as the natural production of CO2from yeast fermentation. In this study, we investigate differences in mosquito capture rates from the Centers for Disease Control and Prevention (CDC) light traps baited with dry ice compared with traps baited with yeast fermentation of several carbohydrate sources over 23 trap-nights. Results demonstrated the ability of yeast-generated CO2to effectively attract mosquitoes to a CDC trap, regardless of carbohydrate source. Total collections of mosquitoes using dry ice were significantly higher than collections from yeast-generated CO2sources. However, mosquito community structure, i.e., the species and relative capture rate of each species, was represented comparably across collections regardless of CO2source. Volatiles produced by yeast fermentation were analyzed by carbohydrate source, revealing a suite of compounds, possibly synergistic, enhancing effects with CO2on mosquito collection capability compared with the amount of CO2used to attract mosquitoes.
