摘要：

为了探索番茄茎叶提取物对菜粉蝶生物活性的影响。采用水蒸气蒸馏法从茴香(Foeniculum vulgare)茎叶中提取获得其挥发性物质，测定了茴香提取物在室内对菜青虫的拒食作用及对菜粉蝶的产卵忌避作用。结果表明：茴香粗提取物对菜青虫3龄幼虫具有较强的拒食活性，且非选择性的拒食作用均大于选择性的拒食作用；茴香提取物对菜粉蝶的产卵具有较强的忌避作用。

Abstract:

This paper objective was to explore biological activity of extracts from Foeniculum vulgare to Pieris rapae. Extract volatile matter was extracted from stem and leaves of Foeniculum vulgare Mill by steam distillation. Biologial activity of antifeedant effect and oviposition repellent on Pieris rapae L was tested with extraction of Foeniculum vulgare. The results showed that extracts of Foeniculum vulgare have strong antifeedant effect on Pieris rapae 3-instar larvae, which the antifeeding activities of Pieris rapae L. of non-choice was higher than that of choice tests. Moreover, that extracts of Foeniculum vulgare had strong effect of repellent effect on Pieris rapae.
