摘要
【目的】筛选出新疆阿克苏地区桃小食心虫Carposina sasakii Matsmura防控效果最佳的迷向装置,提出适宜当地基于昆虫性信息素迷向干扰的防治技术。【方法】定点监测桃小食心虫成虫发生动态,设计在枣园选择距地面3.5与2 m处悬挂迷向丝、迷向管以及缓释迷向袋等不同类型迷向装置,监测并计算其迷向率与蛀果率,筛选适宜高效迷向装置和悬挂高度。【结果】迷向丝、迷向管和缓释迷向袋悬挂高度2与3.5 m蛀果减退率分别为77.36%和90.00%、98.42%和93.15%、93.69%和94.21%;不同迷向装置悬挂高度2与3.5 m,平均迷向率分别为94.81%和89.38%。三种迷向装置防治效果存在明显差异。迷向管控制效果最优,其次为缓释迷向袋的防治效果,迷向丝的防治效果相对较低。不同迷向装置在悬挂高度3.5 m的防治效果优于悬挂高度2 m的防治效果。【结论】在枣园采用每667m^(2)有效成分为顺-7-二十碳烯-11-酮的三种装置中,控制有效成分含量3 g/667m^(2),配置迷向丝40个/667m^(2)、迷向管20个/667m^(2)和缓施迷向袋6个/667m^(2)均有较好的防效。生产中可使用迷向管和缓释迷向袋用于防治桃小食心虫。
【Objective】The objective of this study was to select the best fan device for the best prevention and control effect of Carposina sasakii Matsmura in Aksu region of Xinjiang,and to propose appropriate control measures based on insect sex pheromone fan jamming technology.【Methods】By monitoring the dynamics of Carposina sasakii Matsmura adult insects at a fixed point,it was designed to hang different types of lost devices such as lost silk,lost tubes and slow-release lost bags at 3.5 m and 2 m from the ground in the jujube garden,monitor and calculate their vacade rate and fruit borer rate,and screen suitable and efficient vagus devices and suspension heights.【Results】The results showed that the hanging height of the lost silk,the lost tube and the slow-release bag were 77.36%,90%,98.42%,93.15%,93.69%and 94.21%,respectively.The suspension heights of different fan devices are 2 m and 3.5 m,and the average fan rate is 94.81%and 89.38%,respectively.There are obvious differences in the prevention and control effects of the three kinds of lost devices.The results show that the control effect of the fan tube is optimal,followed by the prevention and control effect of the slow-release lost bag,and the control effect of the lost wire is relatively low.The control effect of different vagus devices at a suspension height of 3.5 m is better than that of a suspension height of 2 m.【Conclusion】A In the jujube orchard,the active ingredient cis-7-eicosene-11-ketone per mu was adopted,and the active ingredient content per mu was controlled by 3 g,and the configuration of 40 mist silk/mu,20 mist tubes/mu and 6 mist bags with slow application had good control effects.In production practice,it is recommended to use the Misty tube and the slow-release Misty bag for the control of Carposina sasakii Matsmura.
