| 摘 要： | 【目的】寻找新的小菜蛾生物防治方法，为植物源农药的研究和开发提供科学依据。【方法】以10种产于广西的楝科、番荔枝科、无患子科和报春花科植物提取物对小菜蛾成虫进行室内产卵忌避作用试验。【结果】以地黄连（Melia sinica）、香椿（叶）（Toona sinensls）、番荔枝（Annona squamosa）、四瓣米仔兰（A．terapetala）、灵香草（Lysimachia foenurn-graeeurn）等植物提取物处理后48h对小菜蛾成虫的产卵忌避率分别为86．21％、94．69％、97．92％、98．91％和100．00％。【结论】地黄连、香椿（叶）、番荔枝、四瓣米仔兰、灵香草等5种植物对小菜蛾成虫有强烈的产卵忌避作用，在蔬菜害虫生态控制中均具有广阔的应用前景和开发潜力。

| Abstract: | Objective] The objective of the current study was to explore some biological control methods against Plutella xylostella （L.）. Method] The efficiency of extracts taken from 10 different plants （belonging to families meliaceae, annonaceae, sapindaceae and primulaceae） in preventing the oviposition in Plutella xylostella （L.） adults have been observed under laboratory conditions. Result] The average oviposition deterrent rates of Plutella xylostella （L.）. adults treated for 48 hour with extracts of Melia sinica, Toona sinensls （leaf） ,Annona squamosa, A. terapetala and Lysimachia foenum-graecure were 86.21, 94.69, 97.92, 98.91 and 100.00%, respectively. Conclusion] Five plants, viz., Melia sinica, Toona sinensis （leaf） ,Annona squamosa, A. terapetala and Lysimachia foenum-graecum were found to have the best control effects on oviposition of Plutella xylostella （ L ） adults, and they have broad application prospects and exploration potential as biological control agents against vegetable pests. |
