【目的】在室内研究绿盲蝽Apolygus lucorum(Meyer-Dür)分别对抗性和敏感棉花品种趋向选择性,为棉花抗盲蝽品种选育和绿盲蝽的综合治理提供理论依据。【方法】以洁净空气为空白对照,在室内采用"Y"型嗅觉仪观察记录不同学习经验处理的绿盲蝽对两对棉花品种:灵-29(抗)vs.科林08-23(感)、07生试6号(抗)vs.抗病单株-1(感)趋向选择性。【结果】有学习经验和无学习经验的绿盲蝽都趋向选择敏感棉花品种,抗性棉花品种对供试昆虫有显著驱避性;有/无学习经验的绿盲蝽都显著趋向选择绿盲蝽胁迫危害后代感性棉花品种。【结论】整体上,健康棉花处理下,绿盲蝽对抗性品种趋性选择明显低于敏感品种。但是对危害诱导的棉株处理,并未表现出一致的趋性。
[Objectives] To provide a theoretical basis for breeding cotton varieties resistant to Apolygus lucorum(Meyer-Dür) and improve the IPM of this pest. [Methods] With pure air as the blank control, we explored the relative preference of experienced or inexperienced A. lucorum for the odors of two cotton varieties(lines): Ling-29(resistant) vs. Kelin08-23(susceptible), 07 Shengshi6(resistant) vs. Kangbingdanzhu-1(susceptible) in a "Y" tube olfactometer. [Results] Both experienced and inexperienced A. lucorum significantly preferred the susceptible cotton varieties Kelin08-23 and Kangbingdanzhu-1 to the resistant varieties, Ling-29 and 07 Shengshi. Furthermore, A. lucorum significantly preferred susceptible cotton plants that had been previously damaged by A. lucorum. [Conclusion] Generally speaking, A. lucorum significantly preferred intact susceptible cotton varieties to intact resistant cotton varieties. But A. lucorum insignificantly preferred induced susceptible cotton varieties to induced resistant cotton varieties.
