绿盲蝽和中黑盲蝽对不同抗性和虫害处理棉花的选择趋性

研究绿盲蝽Apolygus lucorum和中黑盲蝽Adelphocoris suturalis对不同抗性和虫害处理棉花的选择趋性，为棉盲蝽的综合治理提供理论依据。本研究以抗性棉花品种BR-S-10（抗性品种）和感性棉花品种科林08-15（感性品种），以及绿盲蝽和中黑盲蝽分别危害处理后的该两种棉花植株为试验材料，以纯净空气为空白对照，共成对设置15个气味源组合，采用“Y”型昆虫嗅觉仪室内研究了绿盲蝽和中黑盲蝽对不同抗性和虫害处理棉花的选择趋性。结果表明，绿盲蝽显著选择感性品种、中黑盲蝽危害感性品种和绿盲蝽危害感性品种。中黑盲蝽显著选择绿盲蝽危害感性品种、中黑盲蝽危害感性品种和感性品种。总的来说，两种棉盲蝽趋向于选择敏感棉花品种，抗性棉花品种对供试昆虫有显著趋避性；绿盲蝽显著趋向选择中黑盲蝽危害感性品种和绿盲蝽危害感性品种，中黑盲蝽显著趋向选择绿盲蝽危害感性品种和中黑盲蝽危害感性品种。

Selective preferences of Apolygus lucorum and Adelphocoris suturalis (Hemiptera:Miridae)to cotton plants with different resistance levels and damaging treatments

Studying on the selective preferences of Apolygus lucorum and Adelphocoris suturalis (Hemiptera: Miridae) to cotton plants with different resistance levels and damaging treatments could help us establish a theoretical basis for IPM of cotton bugs. In this study, we used plants of the resistant variety BR-S-10 and the susceptible variety Kelin 08-15 and the plants of these two cotton varieties damaged by A. lucorum and A.suturalis bugs respectively as tested materials, and fresh air as the blank control, and a total of fifteen pair combinations of source odor were formed to investigate the taxis responses of A. lucorum and A. suturalis to cotton plants with different resistance levels and damaging treatments with Y-shaped olfactometer in the laboratory. The results indicated that the selective preferences of A. lucorum were in the order of the susceptible variety, the susceptible variety damaged by A. suturalis and the susceptible variety damaged by A. lucorum, sequentially. However, A. suturalis preferred to the susceptible variety damaged by A. lucorum, the susceptible variety damaged by A. suturalis and the susceptible variety observably. In general, two mirid species tended to significantly choose the susceptible cotton varieties, and showed an aversion to the resistant cotton plants. A. lucorum tended to choose the susceptible variety damaged by A. suturalis and the susceptible variety damaged by A. lucorum, while A. suturalis preferred to the susceptible variety damaged by A. lucorum and the susceptible variety damaged by A. suturalis.
