摘 要 【目的】 迷向技术是当前防控梨小食心虫（Grapholitha molesta (Busck)的主要绿色技术之一，其防控效果取决于迷向丝产品质量及施用方法。为了探究该技术在防治梨小食心虫的田间控害效果，对几种广泛使用的主流迷向丝产品进行了田间定量测定。【方法】 选取有代表性的诱尔、宁录生态、神绿植保和澳福姆4种迷向丝产品，于2020年7月在烟台市莱阳市梨园按40根/667 m2的密度悬挂，选择2种诱捕器监测梨小食心虫种群动态，计算不同迷向丝的迷向率、蛀果/蛀梢率，同时比较2种诱捕器的诱捕效果。【结果】 4种迷向丝的迷向率均高于80%，各处理区迷向丝产品的迷向效果（P>0.05）和蛀果/梢率（P>0.05）差异不显著，蛀梢率均低于3%，蛀果率均低于2%。2种监测诱捕器的诱捕结果存在显著性差异（P<0.05）。【结论】 4种主流迷向丝防控效果差异不大，均能达到理想的防治效果，因此在梨园利用迷向法控制梨小食心虫是高效的绿色防控技术。
英文摘要：
Abstract [Aim] To determine the relative effectiveness of different sex pheromone products for disrupting the mating of Grapholitha molesta (Busck) in a pear orchard. [Methods] Four brands of mating disruption products; You’er, Ninglu Shengtai, Shenglv Zhibao and Aofumu, were tested in a pear orchard in Laiyang City in July, 2020. Pheromone dispensers were hung in pear trees at a density of 40 per 667 m2 and 2 kinds of traps were operated during the same period. In addition, the ratio of damaged fruit and shoots were calculated as an indicator of effectiveness of control. [Results] There were no significant differences among the 4 brands of mating disruption products tested; all were more than 80% effective and achieved fruit and shoot damage ratios of< 2% and 3%, respectively. [Conclusion] There are no significant difference between the 4 brands of mating disruption products tested. All four products should therefore be effective for disrupting the mating of G. molesta damage in pear orchards.
