A synthetic blend of chemicals comprising volatiles released by the human body has been shown to be an effective attractant for female Aedes aegypti in olfactometer bioassays with laboratory-reared mosquitoes. We report the laboratory evaluation of Ae. aegypti response to a synthetic blend tested with 4 types of mosquito traps (CDC model 512, CDC model 1012, CFG, and Fay-Prince traps). Aedes aegypti females were attracted significantly by the blend. The higher release rate of attractant (320.2 +/- 10.71 mg/h) more efficiently attracted mosquitoes than the lower release rate (42.0 +/- 2.3 mg/h). Although both the Fay-Prince and CFG traps caught higher number of mosquitoes than the other traps, only the CFG trap caught a statistically significant greater number of mosquitoes. The results suggest that the synthetic blend is effective in attracting Ae. aegypti females under controlled laboratory conditions (i.e., a closed system). Further studies are needed to evaluate the efficacy of this blend in baited traps under field conditions.
在对实验室饲养的蚊子进行的嗅觉仪生物测定中，一种由人体释放的挥发性化学物质组成的合成混合物已被证明是埃及伊蚊雌蚊的有效引诱剂。我们报告了埃及伊蚊对用4种类型的诱蚊器（疾控中心512型、疾控中心1012型、CFG和费伊 - 普林斯诱蚊器）测试的合成混合物的实验室评估。埃及伊蚊雌蚊被该混合物显著吸引。引诱剂释放速率较高（320.2±10.71毫克/小时）比释放速率较低（42.0±2.3毫克/小时）更有效地吸引蚊子。虽然费伊 - 普林斯诱蚊器和CFG诱蚊器捕获的蚊子数量都比其他诱蚊器多，但只有CFG诱蚊器捕获的蚊子数量在统计学上显著更多。结果表明，该合成混合物在受控实验室条件下（即封闭系统）对吸引埃及伊蚊雌蚊有效。需要进一步研究以评估该混合物在野外条件下诱饵诱蚊器中的功效。
