Comparison of Volatiles and Mosquito Capture Efficacy For Three Carbohydrate Sources In A Yeast-Fermentation CO 2 Generator.
Journal of the American Mosquito Control Association(2016)
摘要
Mosquito surveillance in remote areas with limited access to canisters of CO or dry ice will benefit from an effective alternative CO source, such as the natural production of CO from 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 CO to 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 CO sources. However, mosquito community structure, i.e., the species and relative capture rate of each species, was represented comparably across collections regardless of CO source. Volatiles produced by yeast fermentation were analyzed by carbohydrate source, revealing a suite of compounds, possibly synergistic, enhancing effects with CO on mosquito collection capability compared with the amount of CO used to attract mosquitoes.
