中文摘要： 本文研究了红心蜜柚园和新余蜜橘园中诱捕器悬挂高度、设置距离对性诱剂诱集柑桔潜叶蛾Phyllocnistis citrella Stainton雄虫效果的影响。结果表明，诱捕器悬挂的垂直高度明显影响性诱剂对柑桔潜叶蛾雄虫诱集量，同时这个影响随着高度相对树干的水平位置变化而变化。诱捕器最佳悬挂位置是三分之二树高的树冠底部边缘。
英文摘要：The influence of height on the effectiveness of sex pheromone traps to attract male citrus leafminers,Phyllocnistis citrella Stainton,in an orchard of underage red heart pomello and mature Xinyu tangerine trees,was studied.The results revealed that trap height had an obvious effect on capture success which was also dependent on the horizontal distance of traps from the tree trunk.The results also revealed that the bottom edge of the canopy,two thirds of the way up the tree,was the best location for traps.
