几种人体气味物质对淡色库蚊雌成虫的引诱和驱避作用

该文采用“Y”型嗅觉仪测定了丙酮、氨水、癸二酸、正庚酸、环己烷羧酸和肉豆蔻酸等 6种人体气味物质对淡色库蚊雌成虫的引诱和驱避作用。试验结果表明 ,与对照相比 ,6种人体气味物质中 ,仅0 1mg L正庚酸和 1 0mg L丙酮 +1 0mg L氨水对淡色库蚊雌成虫具明显的引诱作用。而 1 0mg L丙酮+1 0 0 0 0mg L氨水和 1 0mg L丙酮 +1 0 0 0mg L氨水则对淡色库蚊雌成虫有明显的驱避作用。其它化合物或处理浓度则对淡色库蚊雌成虫无明显的引诱或驱避作用。

Attractive and repellent activities of several human skin volatiles on the female adults of Culex pipiens pallens

The attractive and repellent activities of acetone, ammonia solution, sebacic acid, n-heptanoic acid, cyclohexane carboxylic acid, and myristic acid against the female adults of Culex pipiens pallens were determined by Y-type olfactometer in the laboratory. The results indicated that among the six compounds tested, compared with control, the 0.1 mg/L n-heptanoic acid solution and the mixture of 10 mg/L acetone solution and 10 mg/L ammonia solution attracted significantly the female adults, and the 10 mg/L acetone solution mixed with 10?000 mg/L or 1?000 mg/L ammonia solution had significant repellent action to the female adults. The other compounds or treatment concentrations had no clear attractive or repellent action to the female adults.
