摘要: 为了科学评估多年迷向防治对桃园梨小食心虫的实际防控效果,并完善优化桃园害虫性信息素科学应用技术,在江苏省无锡市惠山区5个乡镇大面积连片桃园内连续4年使用迷向丝防治梨小食心虫,并实时监测调查,分析各年度桃园内梨小食心虫种群消长动态,抽样法调查统计桃树折梢率。结果显示,多年迷向防治可以有效降低桃园梨小食心虫种群发生数量,各乡镇桃园内虫口基数逐年减少;洛社和钱桥2个乡镇2021年迷向防治处理区梨小食心虫平均迷向率在94.37%以上;2021年阳山镇迷向防治区平均折梢率为1.24%。结果表明大面积且连续使用迷向防治法对桃园梨小食心虫具有很好的防控效果。

Abstract: Control of Grapholita molesta by using sex pheromone mating disruption was practiced in peach orchards for four consecutive years in five towns of Huishan, Wuxi, Jiangsu Province. For improvement and optimization of the technology, the results were evaluated using real-time monitoring of the population dynamics of G. molesta in peach orchards and sampling of the shoot damage. The results showed that the multi-year sex pheromone mating disruption method effectively reduced the occurrence of G. molesta in growing seasons, and that the population base of G. molesta in offseason decreased year by year. In 2021, the average mating disruption rate of G. molesta in the treated areas in Luoshe and Qianqiao were more than 94.37%. In 2021, the average shoot tip damage rate in treated area in Yangshan town was as low as 1.24%. The results show that the large-area and longtime continuous application of mating disruption method in peach orchards has achieved a good control of G. molesta.
