摘    要:
目的研究不同物理、化学因子对致倦库蚊的引诱效果,以更好地设计改进新一代灭蚊器。方法使用Y形嗅觉测试仪测定化学因子(尿素、乳酸、丙三醇、十二烷酸、十四烷酸、十六烷酸、壬醛)以及物理因子(声波和可见光)对致倦库蚊成虫的引诱作用;将致倦库蚊成虫逐只放入Y形嗅觉测试仪,统计飞入处理端的个体数,通过比较得出对致倦库蚊具有较好引诱效果的物理、化学因子。结果对致倦库蚊具有较高引诱率的化学因子有尿素(10 mg/L)、乳酸(1000 mg/L)、十六烷酸(10 mg/L)和壬醛(0.1 mg/L);物理因子中150 Hz的正弦波和380 nm的可见光分别对致倦库蚊具有较高引诱率。结论可将上述引诱效果较佳的物理、化学因子引入到灭蚊器的设计生产中,以提高灭蚊效率。

关 键 词:致倦库蚊  化学引诱  物理引诱

Abstract:
Objective To observe the trap effects of several different physical and chemical attractants on adult Culex pipiens quinquefasciatus,providing better designs of new mosquito trap devices.Methods The "Y"-tube olfactometer was used to measure the trap effects of seven chemicals(urea,lactic acid,glycerol,dodecanoic acid,tetradecanoic acid,hexadecanoic acid and nonyl aldehyde) and two physical attractants(sound and visible light) on adult Cx.pipiens quinquefasciatus.The number of individuals attracted by the tested attractants was calculated and compared among the groups.Results Chemical attractants including urea(10 mg/L),lactic acid(1000 mg/L),hexadecanoic acid(10 mg/L),nonyl aldehyde(0.1 mg/L) and physical attractants including 150 Hz sinus tone and 380 nm visible light had better mosquito trap effects.Conclusion The chemical and physical attractants mentioned above can be introduced to the design of mosquito trap devices to improve the efficiency of mosquito control.
Keywords:Culex pipiens quinquefasciatus  Chemical attractants  Physical attractants
