| 摘 要： | 为了引进推广果园害虫绿色防控技术,2014年4月至7月在上海市浦东新区桃园对240mg/根梨小食心虫性信息迷向素防治梨小食心虫效果进行试验。结果表明,从花期到采收期,迷向处理园梨小食心虫成虫数量明显低于对照园。在495根/hm2和720根/hm2密度处理区,越冬代、第1代、第2代梨小食心虫雄虫迷向率均可达90%以上,种群数量减退率达78.23%~85.15%;迷向丝处理区蛀梢防效达72.73%~95.32%,蛀果防效达78.26%~95.65%,果实品质和产值高于常规对照区,经济效益显著。

| Abstract: | In order to promote the green crop pest control techniques in the orchard,experiment of mating disruption was conducted by using 240mg/bar sex pheromones in peach orchard of Pudong,Shanghai from April to July 2014.The results showed that the mumber of G.molesta in treated peach orchards was much lower than that in untreated orchards from flowering to harvest. Percentage of mating disruption reached 90% in overwintering,first and second generation G.molesta. With 495 bars per hm2 and 720 bars per hm2,reduction rates of G molesta ranged from 78.23% to 85.15%.The control effect of feeding shoots was 72.73%-95.32%,while for the infested fruits it was 78.26%- 95.65%.Meanwhile,quality and output also increased significantly by using this control technique. |
