摘　　要：为推广梨小食心虫性信息素迷向剂(澳福姆)在桃园防治中的应用,选择江苏省太湖阳山镇地区的桃园进行梨小食心虫迷向丝推广试验,以附近的永强合作社桃园为对照,并在迷向区和对照区利用梨小食心虫性诱芯监测调查桃园梨小食心虫的发生动态,评价性信息素迷向丝对梨小食心虫的田间防治效果。结果表明,迷向丝处理区梨小食心虫的种群数量显著低于对照区。太湖阳山桃园迷向丝处理区梨小食心虫的迷向率为97.33%;虫害出现初期折梢防效为66.67%;果实成熟期蛀果防效为80.00%。梨小食心虫性信息素迷向丝可有效降低桃园梨小食心虫引起的蛀梢和蛀果数量,在桃园中对梨小食心虫具有很好的防控效果。In order to popularize the application of a sex pheromone-baited product(Isomate-OFM)topest control in peach orchards,we conducted an experiment on the popularization of sex pheromone-baited disruption trap for Grapholita molestas(Busck)in peach orchards in Yangshan town in Taihu lake,Jiangsu Province,and the orchard of Yongqiang cooperative nearby was used as a reference.The occurrence dynamics of Grapholita molestas in peach orchards were investigated by the sex pheromone monitoring on Grapholita molestas in the disruption area and the contrast area,so as to evaluate the control effect of the sex pheromone-baited product on Grapholita molestasin orchards.The results show that the population of Grapholita molestasin the treatment area was significantly lower than that in the contrast area.In Yangshan peach orchard around Taihu Lake,the disruption rate of Grapholita molestas in Yangshan area was 97.33%,the control effect of broken treetops at the initial stage of insect pest control was 66.67%,and the control effect of fruit boring during fruit ripening was 80.00%.The sex pheromone-baited disruption trap for Grapholita molestas can effectively reduce the number of branch and fruit boring caused by Grapholita molestas,and has a good control effect on Grapholita molestas in peach orchards.
