摘要：室内测定了31种植物的乙醇提取物对柑橘全爪螨的杀螨活性。结果表明:小茴香等4种植物的活性较高,24 h校正死亡率大于90%;藁本等7种植物的活性中等,校正死亡率为60%~90%;其余植物提取物的校正死亡率在60%以下。进一步测定了4种植物提取物对柑橘全爪螨的雌成螨和卵的触杀毒力,表明:小茴香对柑橘全爪螨的毒力最高,LC50值分别为0.065 8 g/L和144.180 5 g/L,可以作为下一步的研究对象。

Abstract: The acaricidic activities of ethanol extracts of 31 plants against Panonychus citri were measured in the laboratory.The results showed that the extracts of 4 plants(Foeniculum vulgare,etc.) had high activity(corrected mortality rate>90%) 24 hours after treatment;the extracts of other 7 plants(Mahonia fortunei(Lindl.) Fedde,etc.) had moderate activity(corrected mortality rate 60%-90%);the rest were low in activity,with their corrected mortality rate below 60%.Contact toxicity curve of the extracts of the 4 plants were further tested.The extract from the seeds of Foeniculum vulgare had the highest activity level against the female adults and eggs of P.citri,with a LC50 value of 0.065 8 g/L and 144.180 5 g/L.F.vulgare should be studied in the future.
