摘要
[目的]研究蒌蒿杀虫成分对菜粉蝶的生物学活性。[方法]在微波辅助加热条件下,以乙醇、乙醚、水、甲苯为溶剂对蒌蒿进行浸提,测定各溶剂提取物对菜粉蝶幼虫的拒食、胃毒、触杀和熏蒸活性。[结果]各溶剂提取物对菜粉蝶幼虫均表现出一定的拒食、胃毒、触杀和熏蒸活性,其中,以乙醇提取物的生物活性最强。[结论]该研究结果可为开发利用蒌蒿植物源杀虫剂提供参考。
[Objective]The biological activity of insecticidal components of Seleng Wormwood on cabbage butterfly(Pieris rapae) was studied.[Method]With the assisted condition of microwave heating,ethanol,ethyl ether,water and methylbenzene were selected as solvent to extract Seleng Wormwood,the antifeeding,stomach poisoning,contact toxicity and fumigation activities of various solvent extracts against cabbage butterfly were determined.[Result]Various solvent extracts all showed certain antifeeding,stomach poisoning,co...
