摘要:

【目的】筛选核桃园中苹果蠹蛾和梨小食心虫最佳防治与迷向丝放置密度与高度。【方法】于2021~2022连续两年在核桃园设置不同悬挂密度(300、450、600根/hm2)和高度(6~8 m、8 m、6 m)的迷向丝,通过田间迷向干扰试验,测定不同悬挂密度和高度的迷向丝对苹果蠹蛾和梨小食心虫的防治效果。【结果】与对照相比,设置密度为300、450、600根/hm2的苹果蠹蛾/梨小食心虫混合迷向丝和苹果蠹蛾、梨小食心虫迷向丝的迷向率和蛀果率之间存在显著差异(P<0.05),高密度处理的迷向丝迷向效果最好,且相同密度处理的各处理苹果蠹蛾/梨小食心虫混合迷向丝与苹果蠹蛾、梨小食心虫迷向丝迷向率和蛀果率之间无显著差异;与对照相比,迷向丝悬挂高度为6~8 m(双层)、8 m、6 m的迷向率和蛀果率之间存在显著差异(P<0.05),悬挂高度为8 m的迷向丝对苹果蠹蛾和梨小食心虫的迷向效果最佳,迷向率分别达到了96.41%、99.71%,防效达到了90.70%。【结论】核桃园苹果蠹蛾/梨小食心虫混合迷向丝最佳设置密度为450根/hm2,最佳悬挂高度为8 m为宜,大面积连片使用1年以上。

Abstract:

【Objective】To explore the mode of scientific use of sex pheromone for Cydia pomonella L. and Grapholitha molesta Busck control in walnut orchard. 【Methods】In this study, different suspension densities (300, 450, 600 roots/hm2) and heights (6-8 m, 8 m, 6 m) of the sex pheromone were set in walnut orchards for two consecutive years from 2021 to 2022, and the effects of different suspension densities and heights of the sex pheromone on the control of C. pomonella L. and G. molesta Busck were determined through field bewildering interference tests.【Results】Compared with the control, there were significant differences (P<0.05) in the disorientation rate and fruit infestation rate of mixed sex pheromone of C. pomonella L. and G. molesta Busck, sex pheromone of C. pomonella L. and G. molesta Busck with the density of 300, 450, 600 roots/hm2. The tropism effect of high density treatment was the best, and there was no significant difference between the disorientation rate and fruit infestation rate of mixed sex pheromone of C. pomonella L. and G. molesta Busck, sex pheromone of C. pomonella L. and G. molesta Busck with the same density treatment. Compared with the control, there was a significant difference (P<0.05) between the rate of disorientation and the rate of fruit decay when the suspension height of the disorientation wire was 6-8 m (double layer), 8 m and 6 m. The disorientation effect of the disorientation wire with a suspension height of 8 m on the codling moth and the oriental fruit moth was the best, the disorientation rate reached 96.41% and 99.71%, respectively, and the control effect reached 90.70%.【Conclusion】Considering the economic cost and control effect in production, it is suggested that the optimal setting density of mixed sex pheromone of C. pomonella L. and G. molesta Busck in walnut orchard is 450 roots/hm2, the optimal suspension height is 8 m, and it is recommended to use it in a large area for more than 1 year.
