中文摘要：
【目的】 从保护生态环境兼顾防治害虫的角度出发，研究不同防治方法对麦蚜种群动态的影响，为麦蚜的田间防治提供理论依据。【方法】 本试验分别设置不同的麦蚜防治田（空白对照田、黄板田、糖醋液田、诱芯田、诱虫灯田、综合防治田），在小麦生长期观察不同的防治田内麦蚜的种群动态的变化。【结果】 诱虫灯对有翅蚜的防治效果要好于黄板和糖醋液，但对禾谷缢管蚜Rhopalosiphum padi (Linnaeus)有翅蚜的诱捕效果不明显，黄板和糖醋液对有翅蚜和无翅蚜均有防治效果，多种防治方法共同利用对麦蚜种群数量有一定的防治效果。【结论】 多种防治方法共同使用的防治效果优于单一防治方法，诱虫灯、糖醋液、黄板、诱芯对不同种类麦蚜的防治效果不同。在田间使用时应注意不同时期采用不同的防治方法。
英文摘要： [Objectives] To assess the effects of different control methods on the population dynamics of wheat aphids and provide a theoretical foundation for controlling wheat aphids in the field. [Methods] The effects of different kinds of control (yellow board traps, sugar vinegar mixture, lures, light trapping and comprehensive prevention) on the population dynamics of wheat aphids were measured during the wheat growing period and compared to those in a non-treatment field. [Results] Light trapping was superior to yellow board traps and sugar vinegar mixture, but its effect on winged Rhopalosiphum padi was not obvious. The effects of yellow board traps and sugar vinegar mixture liquid were obvious. Integrating different control methods was very effective in controlling wheat aphids. [Conclusion] A variety of control methods are better than one. The effectiveness of light trapping, sugar vinegar mixture, yellow board traps and lures varied depending on the species of wheat aphid. Different control methods may be appropriate for different stages of the wheat growth period.
