| 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. |
