| 摘 要： | 采用索氏提取法制取艾蒿（Artemisia argyi）乙醇粗提物并设定5个不同的浓度，观察其对茶尺蠖3龄幼虫的生物活性。结果表明，各处理对茶尺蠖3龄幼虫具有较强的触杀、胃毒活性和一定的拒食及抑制生长发育的作用，提取物浓度越高，效果越明显。当提取物在100 mg/mL浓度下，处理72 h后，触杀和胃毒活性中的校正死亡率分别高达66.14%、78.16%；此浓度下，12 h和24 h的拒食率分别达到了56.77%和46.01%；24 h和48 h的生长抑制率分别为54.83%和68.32%。数据显示：艾蒿乙醇粗提物对茶尺蠖具有较好的毒杀作用，有开发成植物源杀虫剂的潜力，符合当前无公害茶叶生产之急需。

| Abstract: | Preparation of the Artemisia argyi by Soxhlet extraction and set the alcohol extracts of 5 different concentrations,observation of the Artemisia argyi extracts were bio-assayed against Ectropis obliqua larva.Results indicated that the extracts had many functional patterns against the larvae of Ectropis obliqua as anti-feeding,contacting toxicity,stomach poisoning and inhibiting growth activities.The higher concentration,the more obviously the effect on the pest was.In the test of contacting toxicity and sto... |
