摘　　要：【目的】研究油桃大棚性诱剂悬挂高度及田间风向对诱集的效果。【方法】不同悬挂高度50、100和150cm处以及田间风向对东、中、西等3个方位诱集效果。【结果】梨小食心虫性诱剂在油桃大棚上的最佳悬挂高度为100 cm;和全天最多风向与逐日考察诱集量最大的诱捕器方位相吻合,其吻合率为72.0%,若将诱集量为次多值的诱捕器计算在内,则其吻合率高达92.0%。【结论】在测报和防治中使用诱捕器法为好。【Objective】The research aimed to study the trap efficiency of different suspension heights and wind directions.【Method】The trap efficiency in the greenhouse with different suspension heights of 50 cm,100 cm,150 cm and wind directions from the middle,east and west was compared in this study.【Result】The best suspension height of sex attractant lure on oriental fruit moths in a greenhouse was 100 cm,consistent with maximum wind direction in the whole day and trapper position of largest trap number.The coincidence degree was 72.0%.If trappers with the second greatest number of trapped insects were counted,the coincidence degree reached as high as 92.0%.【Conclusion】It is better to apply the trapper method to forecast and prevent the insect.
