中文摘要：
【目的】 明确我国华北地区棉盲蝽优势种对不同种棉花品种的选择偏好性，以及这几种盲蝽的种群动态及发生规律。【方法】 2013和2014年通过小区随机排列田间系统调查的方法，比较分析了中黑盲蝽Adelphocoris suturalis (Jakovlev)、三点盲蝽Adelphocoris fasciaticollis (Reuter)和绿盲蝽 Apolygus lucorum (Meyer-Dür )对12个棉花品种的选择偏好性，种群动态及与温度的关系。【结果】 3种盲蝽均对石亚系1号表现出明显偏好性，对N73DeltapineFO表现出明显的不偏好性。棉盲蝽在每年7月初开始危害，7月下旬及8月上旬盲蝽种群密度达到峰值，9月上旬种群密度逐渐降低，9月中下旬盲蝽迁出棉田。在本实验调查的温度范围内（17~35℃），盲蝽种群密度随着温度升高而增大。【结论】 棉盲蝽对不同品种有明显选择偏好性，盲蝽种群大的地区推荐种植盲蝽厌食品种。
英文摘要： [Objectives] To investigate the preference of cotton mirids for different cotton varieties and the population dynamics of these pests. [Methods] 12 cotton varieties were planted in a random plot design in a field in 2013 and 2014. The population dynamics of the main cotton mirids, Adelphocoris suturalis (Jakovlev), Adelphocoris fasciaticollis (Reuter), and Apolygus lucorum (Meyer-Dür ), were then investigated on these plants and the relationship with temperature evaluated. [Results] All three mirids displayed the highest preference for Shiyaxi 1 and the least preference for N73DeltapineFO. Cotton mirids appeared in cotton fields in early July. Their population density peaked at the end of July and early August, and was lowest at the end of September. The population density of mirids increased with increasing temperature within the range of 17-35℃. [Conclusion] Cotton mirids prefer some cotton varieties to others and resistant cotton varieties should be planted in areas with a high population density of mirids.
