| 中文摘要: |
| 农田作物布局作为害虫生态调控的重要内容，一直是保护性生物防治的研究热点。为进一步明确马铃薯田块作物间套作种植模式对马铃薯甲虫种群动态的影响，探索马铃薯甲虫可持续防控的新思路与新方法，本研究在马铃薯甲虫发生期对马铃薯-玉米、马铃薯-向日葵、马铃薯单作3种作物间套作模式进行田间种群数量调查，分析比较不同种植模式下的马铃薯甲虫种群动态差异。结果表明：在马铃薯甲虫发生期，马铃薯单作第二代幼虫为害高峰期出现晚于两种间套作模式，第一代成虫为害高峰期早于两种间套作模式。第二代幼虫为害低峰期（8月26日-9月7日）时，马铃薯-玉米间套作幼虫量显著低于马铃薯单作（P<0.05），马铃薯-玉米间套作幼虫量显著低于马铃薯-向日葵（P<0.05），整个调查期间，马铃薯单作虫量要大于两种间套作。此外，天敌昆虫群落调查表明：间套作玉米异色瓢虫量显著高于马铃薯单作（P<0.05），间套作向日葵的草蛉、食蚜蝇虫量高于马铃薯单作。间套作向日葵或玉米对越冬代马铃薯甲虫的扩散有影响，马铃薯播种初期间套作向日葵或玉米能在一定程度上阻隔马铃薯甲虫的定殖扩散。 |

| As an important part of pest ecological regulation, farmland crop layout has always been a research hotspot of protective biological control. In order to further clarify the effect of intercropping planting patterns on potato field crops on the population dynamics of Colorado potato beetles and to explore new ideas and methods for sustainable control of Colorado potato beetles. In this study, field population surveys were conducted on three crop intercropping modes of potato corn, potato sunflower and potato monocropping during the period of Colorado potato beetle occurrence.The differences in population dynamics of Colorado potato beetles under different planting patterns were analyzed and compared.The results showed that during the Colorado potato beetle occurrence period, the peak period of the second generation of potato single crop larvae appeared later than the two intercropping modes, and the peak period of the first generation adult larvae was earlier than the two intercropping modes. During the low peak period of the second generation larvae (August 26~September 7), the amount of potato corn intercropping larvae was significantly lower than that of potato monocropping (P <0.05) and the amount of potato corn intercropping larvae was significant. It was lower than that of potato sunflower (P <0.05). During the whole investigation period, the amount of potato monocropping was larger than that of two intercropping. In addition, surveys of natural enemy insect communities showed that the amount of Harmonia axyridis in intercropping corn was significantly higher than that in potato monocropping (P<0.05) and the amount of Syrphidae and Chrysopidae in intercropping corn was higher than that in potato monocropping. Intercropping sunflower or corn has an effect on the spread of wintering Colorado potato beetles.Interplanting sunflower or corn during the early sowing period can block the colonization and spread of Colorado potato beetles to a certain extent. |
