【目的】 大豆蚜Aphis glycines (Matsumura) 是危害我国大豆产量的重要刺吸式害虫，茄无网蚜Acyrthosiphon solani（Kaltenbach）是近年来在大豆田发生逐渐呈上升趋势的刺吸式害虫，蚜虫的发生动态严重影响大豆的产量和品质，本试验调查了马铃薯-大豆、玉米-大豆邻作种植模式对大豆田刺吸式害虫及其他主要害虫的种群动态的影响，为精准使用农药防控蚜虫提供依据。【方法】 采用系统调查的方法，研究大豆田刺吸式害虫以及天敌的种群动态，在哈尔滨香坊农场进行马铃薯-大豆、大豆-玉米邻作的种植模式，对其大豆田中大豆蚜、茄无网蚜等刺吸式口器的害虫及天敌动态发生数量进行调查。【结果】 2014年与2015年玉米-大豆、马铃薯-大豆种植模式的大豆田中的大豆蚜数量明显低于对照田，2014年玉米-大豆差异更显著，2015年马铃薯-大豆差异性显著。2014年与2015年玉米-大豆、马铃薯-大豆邻作种植模式的大豆田中的茄无网蚜数量显著低于对照田。而2014年8月温度低于2015年虫量相对高于2015年，虫量高时天敌总群动态也相对较高，达到调控作用。【结论】 玉米-大豆、马铃薯-大豆邻作种植模式能够起到减少大豆蚜和茄无网蚜的为害的作用，并能够减少农药的使用量。

[Objectives] Aphis glycines (Matsumura) is an important piercing-sucking pest that causes significant losses to soybean production in China, while Acyrthosiphon solani (Kaltenbach) is another piercing-sucking pest that has become the focus of increasing interest in recent years. The yield and quality of soybeans is closely related to the population dynamics of the aphids that feed on them. This research explores the effects of potato-soybean-maize intercropping on the population dynamics of piercing-sucking pests, and other main pests, in soybean fields in order to provide guidance for using pesticides to control aphids. [Methods] Systematic investigations of the population dynamics of piercing-sucking pests and their predators in soybean fields were conducted in Xiangfang farm, Harbin in 2014 and 2015. The statistical significance of differences between treatments was assessed using Duncan's new multiple range method in DPS. Data were analyzed with single factor analysis in SPSS. [Results] Numbers of soybean aphids in two intercropped fields were significantly lower than in a monoculture field. In 2014, this difference appeared more significant in the maize-soybean field but in 2015 the potato-soybean fields appeared to have the lowest pest abundance. Numbers of A. solani in the two intercropped fields were also significantly lower than in the monoculture fields. In both years, higher temperatures were followed by an increase in pest populations. However, although the temperature in August, 2014 was lower than that in 2015, the number of insects increased but was regulated by increased predator abundance.  [Conclusions] Maize-soybean and potato-soybean intercropped fields can decrease the losses caused by the soybean aphid and A. solani, and can also reduce the usage of pesticides.
