The mosquito feeding and ovipositional repellency of the major monoterpenoid present in the volatile oil ofHemizonia fitchii (Asteraceae), i.e., 1,8-cineole, was investigated. Although 1,8-cineole did not exhibit any significant mosquito larvicidal activity, it was moderately effective as a feeding repellent and highly effective as an ovipositional repellent against adultAedes aegypti (yellow fever mosquito). The ovipositional repellency of 1,8-cineole, coupled with the presence of severalHemizonia chromenes previously shown to possess mosquito larvicidal activity, may therefore account in large part for the observed suppression of local mosquito populations which was associated withH. fitchii plants in northern California.
我们研究了存在于糙苏属植物（菊科）挥发油中的主要单萜 1,8-桉叶油醇对蚊子的摄食和产卵驱避作用。虽然 1,8-桉叶油醇对蚊子幼虫没有显著的杀灭活性，但它对成体埃及伊蚊（致黄热病蚊子）有一定的摄食驱避作用，而且对产卵也有高度的驱避作用。1,8-桉叶油醇的产卵驱避作用，再加上先前已证明具有杀蚊幼虫活性的几种糙苏色烯的存在，可能在很大程度上解释了在加利福尼亚北部与糙苏属植物有关的当地蚊子种群的观察性抑制现象。
