摘　　要：【目的】为研究红橘(citrus reticulate)精油对橘小实蝇(Bactrocera dorsalis)产卵行为的影响。【方法】用浸泡法测试不同浓度红橘精油处理后杧果上的橘小实蝇产卵量,并对红橘精油进行GC-MS分析。【结果】结果表明,经不同浓度红橘精油处理的杧果上的橘小实蝇着卵量均显著高于对照,且随着红橘精油浓度的提高其产卵量升高。红橘精油主要成分为柠檬烯,松油烯,月桂烯,α-蒎烯,4-异丙基甲苯,芳樟醇等。【结论】初步确定,红橘精油对橘小实蝇产卵具有显著的引诱活性;这些主要成分可能是红橘精油引诱橘小实蝇产卵的主要物质。[Objective] To study the effects of the essential oils from citrus reticulate on oviposition of Bactrocera dorsalis, [Method] The number of eggs of B. dorsalis laid on Mangiferaindica was investigated after the treatment of oil from C. reticulate, and the constituents of oil were analyzed with GC-MS. [Result] The results showed that the numbers of eggs on fruits were significantly higher after the fruits were dipped in the different concentrations of oil and the number of eggs increased gradually with the increase of essential oil concentrations. The main constituents of oil were Limonene, gamma-Terpinen, betaMyrcene, alpha-Pinene, 1-Isopropy--4-Methylbenzene and b-Linalool. [Conclusion] The study suggested that the essential oil from C. reticulate has significant attraction effect on oviposition of B. dorsalis and those volatiles detected possibly are main active components contributed to oviposition attraction.
