31种热带植物乙醇提取物对朱砂叶螨的生物活性研究
Study on the Bioactivity of the Alcohol Extracts of 31 Tropical Plants Against Tetranychus cinnabarinus
摘要
Abstract
The contact activity and repellent effect of the alcohol extracts of 31 tropical plants against Tetranychus cinnabarinus was studied.The results showed that the extract of Helicteres lanceolata DC., Leucas aspera Link, Hunteria zeylanica Gard. Ex Thw. And Clerodendrum inerme Gaertn. Had obvious contact activity to adult T. Cinnabarinus. The average corrected mortalities rates were all above 80% after 24 hours, and the extract of Helicteres lanceolata DC.had the highest contact activity among the extracts tested, with the average corrected mortality being 96.35%. The extracts of other 23 plants had significant repellent effect on the ovipoisition of T. Cinnabarinus and the average repellent rates were above 90%. The extracts of Harrisonia perforate Merr., Mallotus yunnanensis Pax et Hoffm., Fissistigma polyanthum Merr., Litsea variabilis Hemsl, Atalantia buxifolia Oliv. And Milleltia lasiopetala Merr. Had obvious repellent effect to adult T. Cinnabarinus., and the average repellent rates were above 91% after 48 hours.关键词
