摘要：

为了探讨板栗(Castanea mollissima)栗苞挥发物化学成分及其含量，找出对栗园桃蛀螟(Conogethes punctiferalis)具有引诱作用的行为活性物质，采用顶空捕集法和气相色谱质谱联用分析技术，对北京地区桃蛀螟寄主植物板栗的4个主要栽培品种（怀黄、怀九、燕红和实生）幼果期（对应桃蛀螟成虫盛发期）和成熟期的栗苞挥发物进行了检测。结果表明：4个板栗品种的栗苞在幼果期共捕集到10种化合物，其中，4个品种均释放的化合物共有5种，分别为α蒎烯、莰烯、β-侧柏烯、β-蒎烯和(反)-2丁烯酸-2-亚甲基环丙基-2-基酯；柏木脑和3-蒈烯为燕红板栗品种所特有，D-苎烯为怀九、燕红和实生板栗所特有，罗勒烯和法尼醇为怀黄和怀九板栗所特有。另外，成熟期所释放的挥发物种类和数量均较幼果期明显减少。研究结果说明：1）不同生长发育期的板栗栗苞释放的挥发物不同；2）不同板栗品种间既有共同释放的共性化合物，也有品种特异性化合物。

Abstract: In order to identify plantoriginated attractants for forecasting and controlling of the yellow peach moth, Conogethes punctiferalis
in chestnut orchards, volatiles emitted from involucres of four chestnut cultivars (Huaihuang, Huaijiu, Yanhong and Shisheng) widely planted in Beijing area, were collected and analyzed using headspace trapping and GC-MS techniques, during the young fruit period and mature fruit period respectively. The results showed that 10 volatile compounds were emitted from the four chestnut cultivars during the young fruit period, and 5 out of the 10 volatiles were shared in the four cultivars, including α-pinene, camphene, β-thujene, β-pinene, and (E)-2-butenoic acid,2-(methylenecyclopropyl) prop-2-yl ester. Cedrol and 3-carene were only detected in Yanhong cultivar, and D-limonene was only emitted by Huaijiu, Yanhong, and Shisheng cultivars. β-ocimene and farnesol were specifically released by Huaihuang and Huaijiu cultivars. In addition, the kinds and quantity of volatiles during the mature fruit period were both significantly lower than during the young fruit period. The results indicated that the volatiles from involucres of chestnut differed in different growth periods, and that some volatiles were shared by different chestnut cultivars while the others were cultivarspecific.
