中文摘要：通过农作物遗传多样性、物种多样性的优化布局和种植，增加农田的物种多样性和农田生态系统的稳定性，有效地减轻作物虫害的危害，已经成为国际上农业研究的热点和农业害虫防治的发展趋势。多样性种植对昆虫的影响及其作用机制很大程度上取决于对植食性昆虫的行为反应。多样性种植主要通过干扰植食性昆虫的定向、交配、产卵、转移等行为，影响其在作物上定居和繁殖，进而影响其对植物的危害程度。根据国内外研究进展，本文介绍了作物多样性种植对植食性昆虫行为的影响，并讨论了目前存在的问题和研究前景。
英文摘要：Increasing habitat diversity and agro-ecosystems stability by optimum distribution of crop genetic and species diversification in order to reduce pest damage has been a focus in agricultural research and a trend in insect pest control. However, its mechanisms and degree of pest reduction are dependent on a thorough understanding of the behavior of the insect species. The phytophagous insects’ host location, mating, movement, oviposition, and feeding behaviors are disturbed in the diversified cropping system. The effect of diversified cropping on phytophagous insect behavior is thoroughly discussed in this paper based on domestic and foreign research reports, as well as current research problems and future perspectives.
