摘　　要：【目的】探讨苹果蠹蛾性信息素田间应用中的技术问题,为苹果蠹蛾性信息素的科学应用提供理论依据。【方法】采用三角式、飞翼式、水盆式和圆筒式4种诱捕器,较系统地研究了诱捕器类型和悬挂高度、苹果蠹蛾性信息素剂量和纯度等因素对诱捕效果的影响。【结果】三角式和飞翼式诱捕器的诱捕效果较佳;诱捕器设置在树冠中上部的诱捕量极显著高于下部及顶部;每诱芯中苹果蠹蛾性信息素含量为0.75 mg时诱捕效果最佳,剂量低于每诱芯0.25 mg或高于1.5 mg时,诱捕量显著下降;性信息素纯度对诱捕效果影响较大,在每诱芯1.00 mg剂量下,纯度为75%的性信息素诱捕效果较佳。【结论】田间宜采用三角式粘胶诱捕器;每诱芯中含0.75 mg苹果蠹蛾性信息素处理的诱捕效果最佳;性信息素纯度不低于75%即可达到制备诱芯的要求;诱捕器设置在树冠中上部诱蛾效果更好。【Objective】 The research was done to study the applied technology of codling moth＇s sex pheromone in order to provide technical basis for using sex pheromone in field.【Method】 A comparative study was conducted on the efficiency of different dose,pure sex pheromone and hanging height of traps on capture of codling moth.【Result】 The result indicated that there is obvious difference between different dosages.The most effective dose is 0.75 mg.The catches will reduce obviously when the dose is more than 1.5 mg or less than 0.25 mg.The result also indicated that in dosage of 1.00 mg,when the purity is 75%,the traps catch most codling moth which is more effective than others.In this study,we also found the most suitable hanging height of traps on the top-part of orchard;the trapping effects are more significant than the under-part.【Conclusion】 When sex pheromone is used to control codling moth,the best dosage is 0.75 mg,the traps should be hung in the top of trees.The request purity to prepare dispenser rubber stopper is more than 75%.
