摘要: 【目的】研究牧草盲蝽成虫对5种寄主植物选择行为反应,分析其在寄主植物上的种群发生动态,为筛选棉田牧草盲蝽诱集植物提供理论基础。【方法】采用Y-型嗅觉仪,测定牧草盲蝽成虫(雌虫和雄虫)对红花、龙葵、木地肤、反枝苋和棉花的选择行为反应,并利用目测法对5种寄主植物上的牧草盲蝽种群数量进行调查。【结果】牧草盲蝽雌、雄成虫偏好选择木地肤、红花和棉花。5种寄主植物牧草盲蝽(成虫和若虫)种群平均密度差异显著。其中,木地肤中牧草盲蝽(成虫和若虫)种群平均数量最多,显著高于红花、龙葵、反枝苋和棉花;其次为红花。调查时间、寄主植物种类以及调查时间与寄主植物种类的密度交互作用均显著影响牧草盲蝽(成虫和若虫)种群密度。【结论】红花可作为棉田牧草盲蝽潜在的诱集植物。

Abstract: 【Objective】 To explore the behavioral responses of Lygus pratensis (Heteroptera: Miridae) to five host plants and its population dynamics in host plants in the hope of providing a theoretical basis for the selection of trap crop of L. pratensis. 【Methods】 The behavioral responses of Lygus pratensis to safflower (Carthamus tinctorius), Amaranthus retroflexus, Kochia prostrata, Solanum nigrum and cotton were determined by Y type olfactory instrument and the population dynamics of Lygus pratensis on five host plants were investigated by visual observation.【Results】 Y-tube olfactometer assays showed that L. pratensis was highly attracted to volatile derived from Kochia prostrata, safflower and cotton. The density of L. pratensis was significantly affected by sampling date, host plant and interaction between sampling date and treatment host plant. The mean number of L. pratensis on Kochia prostrata was significantly higher than those on other host plants.【Conclusion】 Safflower can be used as the trap crop of L. pratensis.

Key words: Lygus pratensis; host plant; population dynamic; behavioral responses
