中文摘要：
【目的】 糖醋酒液能有效诱集梨小食心虫Grapholita molesta (Busck)，而性诱剂辅助正好使糖醋酒液诱捕效果得以补充。【方法】 本文对6种配方的糖醋酒液、3种窗口形状诱瓶、有无性诱剂辅助、4种高度、5种间距在梨园对梨小食心虫的诱捕效果进行了研究，总结出糖醋酒液对梨小食心虫最佳诱捕效果的设计方案。【结果】 结果表明，在梨园利用糖醋酒液防治梨小食心虫时，选择红糖∶食用醋∶白酒∶清水＝3∶1∶3∶80的糖醋酒液配方，窗口形状为长方形的诱瓶，辅以性信息素诱芯，挂瓶高度为1.5 m，间距为4 m时诱捕效果最佳。【结论】 合理利用糖醋酒液防治梨小食心虫是一种简便有效的方法。
英文摘要：
[Objectives] Sugar-vinegar-spirit liquid can effectively control Grapholita molesta, especially gravid females, whereas sex pheremone lures could work on males. [Methods] This paper studied the effects of using sugar-vinegar-spirit liquid to trap G. molesta in pear orchards under a range of different conditions; 3 shapes of trap opening, the presence or absence of a pheromone lure, 4 trap heights, and 5 different trap spacings. [Results] Optimal trapping was achieved when the ratio of brown sugar∶vinegar∶white spirits∶water was 3∶1∶3∶80, the trap bottle had a rectangular opening, contained a sex pheromone lure, was placed at a height of 1.5 m, and were spaced 4 m apart. [Conclusion] Effective control of G. molesta can be easily achieved with sugar-vinegar-spirit liquid.
