【目的】为性诱剂在杏园防治梨小食心虫提供依据。【方法】利用梨小食心虫性诱剂对新疆库车杏园梨小食心虫进行了使用方法、最佳自制诱捕器种类、1hm2最适诱捕器数量及防治方法的研究。【结果】杏园梨小食心虫3个成虫羽化高峰期分别出现在4月下旬、6月中旬和8月下旬;在板式、管式、瓶式3种自制的诱捕器中,板式胶粘诱捕器的诱虫效果最好,其次是管式诱捕器,瓶式的较差;在发生量较小时诱捕器的数量以90枚/hm2为宜,但在实际推广应用中应随发生量的增大适当增加诱捕器数量;在防治试验中,迷向区的迷向率和防效分别为76.2%和77.78%,诱捕区的迷向率和防效分别为66.11%和90.75%,诱捕区的防治效果较好。【结论】在实际防治中使用诱捕器法为好。
【Objective】 The aim of this study is to provide the basis for sex lure in the prevention and control of pest insects in Apricot orchard. 【Method】 The method was used to study the method of using the insecticidal insecticide of pear to feed the heartworm Apricot pear in Kuqa, the best home-made traps, the optimal number of traps in 1hm2 and its control measures. 【Result】 The results showed that the emergence peak of three adults of Apricot Pear boreal appeared in late April, mid-June and late August, respectively. Among the three homemade traps, plate-type adhesive traps Of the best trapping effect, followed by tube traps, bottle-type poor; in the case of small amount of trap to 90 / hm2 is appropriate, but in the actual promotion of the application should increase with the amount of The number of traps was increased properly. In the control experiment, the rate of fanfall and the control effect were 75.2% and 77.78%, respectively. The rate of curiosity and the control effect of trapping area were 66.11% and 90.75% The effect is better. 【Conclusion】 It is better to use traps in the actual control.
