【摘要】 以采自广西十万大山的51种植物为筛选对象,采用叶碟浸渍法和玻片法分别测定了其甲醇提取物(质量浓度为10 mg/mL)对柑橘全爪螨Panonychus citriMe Gregor和酢浆草如叶螨Tetranychina harti(E-wing)雌成螨雌成螨的毒杀活性。结果表明:苦李根(Rhamnella crenata)、九节(Psychotria ruba)、毛桐(Mallo-tus barbatus)、粉叶鱼藤(根)(Derris glauca)、山漆树(Rhus silvestris)、苦参(Sophora flavescens)毛八角枫(Alangium kurzii)、小叶买麻藤(Gnetum panvifolium)、络石(Trachelospermum jasminoides)、厚叶铁线莲(Clemalis crassifolia)、黑面叶(Breynia fruticosa)等11种植物对酢浆草如叶螨具有显著毒杀活性;络石、山漆树、无根藤对柑橘全爪螨雌成螨具有显著毒杀活性。更多还原

【Abstract】 Fifty-one different plant samples from Shiwandashan Mountain were involved in screening new compounds against mites through methods such as the immersion of leaf disks,the glass piece method and so on.In this process,the toxic activities of the 51 samples′ methanol extracts on female adult mite of and Panonychus citri Me Gregor were determined.The research results are listed as follows: 11 kinds of plants showed good toxic activities on Tetranychina harti(Ewing) female adults.They are Rhamnella crenata,Psychotria ruba,Mallotus barbatus,Derris glauca,Rhus silvestris,Sophora flavescens,Alangium kurzii,Gnetum panvifolium,Trachelospermum jasminoides,Clemalis crassifolia and Breynia fruticosa.Meanwhile,Trachelospermum jasminoides,Rhus silvestris and Cassytha filiformis L.exhibited good toxic activity on Panonychus citri Me Gregor female adults.更多还原
