摘　　要：目的测定桐子叶水提物和醇提物对樟树小爪螨的杀伤活性。方法采用温浸法和索氏提取法提取油桐叶的水提物和醇提物,分别配置不同的浓度,用浸叶法检测不同粗提物对香樟小爪螨的触杀活性。结果在生药浓度为100mg/ml的水提物和50mg/ml醇提物中小爪螨的校正死亡率分别为91.43%和62.5%。结论桐子叶水提物及醇提物对香樟小爪螨都具有杀伤活力,水提物的杀螨活性较强。Objective The activity of crude extracts from Vernicia fordii leaves against Oligonychus Berlese were determined. Methods Using the dynamic warm extraction and ethanol reflux extraction to extract, leaf - dipping method to determine the anti -mite activity. Results Under the contact treatments of 100mg/ml water extract and 50mg/ml ethanol extract, the corrected mortalities of O. Berlese were 91.43% and 62.5%. Conclusion All of the crude extracts have acaricidal activity to some extent, and the activity of water extract is high.
