摘要
在室内条件下通过Y型嗅觉仪测试了淡色库蚊Culexpipiens pallens雌成虫对乳酸、丙酮、氨水、辛醇、正庚酸、对甲酚、间甲酚等7种化学物质的嗅觉反应。结果表明:与对照相比,1和10mg/L氨水,1,10和100mg/L正庚酸,1mg/L辛醇,0.1和1mg/L对甲酚对淡色库蚊雌成虫具有显著的引诱作用。比较各处理的相对引诱率,最高的为10mg/L正庚酸,达50%以上;其他处理相对引诱率均低于40%,最低的为0.1mg/L对甲酚。
Olfactory responses of Culex pipiens pallens female adults to 7 chemicals were investigated in the laboratory using a Y-tube olfactometer. These chemiscals tested were lactic acid, acetone, ammonia solution, octyl alcohol, n- heptanoic acid, p-cresol, and m-cresol. The results indicated that, among the 7 chemicals tested, 1 mg/L and 10 mg/L ammonia solution, 1, 10 and 100 mg/L n-heptanoic acid solution, 1 mg/L octyl alcohol solution, 0.1 mg/L and 1 mg/L p-cresol solution were more attractive significantly than the control to the female adults of C. pipiens pallens, while remaining chemicals showed no significantly attractive effect on the female adults. For the relative attraction rate among all the treatments, 10 mg/L n-heptanoic acid was the highest by above 50 % and the other treatments were lower than 40% with the lowest attraction rate in 0.1 mg/L p-cresol solution .
