摘要: 【目的】 研究棉长管蚜和棉蚜对其胁迫棉花的选择行为。【方法】 以无翅棉长管蚜和棉蚜成蚜为研究对象,测定棉长管蚜和棉蚜对种群密度和不同时间蚜虫胁迫的棉花行为反应。【结果】 不同种群密度棉长管蚜取食胁迫下,棉长管蚜对低密度取食胁迫的棉花与健康植株选择性上不存在差异性,而高密度则存在显著差异;棉蚜对高密度棉长管蚜取食胁迫选择性上存在显著差异。不同种群密度棉蚜取食胁迫下,棉长管蚜对被取食胁迫棉花与健康植株的选择性上不存在差异性,棉长管蚜能够适应棉蚜为害的棉花;而棉蚜对高密度棉长管蚜和棉蚜取食的棉花与健康植株选择性上存在显著差异,取食胁迫密度越高则选择差异性越大。随着棉长管蚜取食胁迫棉花时间的延长,棉长管蚜对短时间取食胁迫的棉花选择性上不存在差异性,而在取食胁迫3、5 d的棉花上存在显著差异;取食棉蚜仅在取食胁迫5 d的棉花上存在显著差异。棉蚜取食胁迫棉花不同时间后,不同受害程度棉花对后期棉长管蚜的寄主选择性不存在显著性差异。【结论】 棉花蚜虫取食偏向选择健康植株,易造成田间扩散,导致棉花受害。棉长管蚜能够适应棉蚜为害的棉花,且与棉蚜长期在田间共存。

Abstract: 【Objective】 In order to clarify the selection behavior of Acyrthosiphom gossypii and Aphis gossypii to cotton plants under feeding stressed by aphids.【Method】 Wingless adults of Ac.gossypii and A.gossypii were used as research objects, the behavioral responses of them to cotton that was stressed by aphids of different population densities and different time were measured.【Result】 Under the feeding stress of different population densities of Ac.gossypii, there were no differences in the selection of Ac.gossypii between healthy plants and low densities stress-cotton, but there were significant differences between high densities. There were significant differences in the selectivity of Aphis gossypii to high density Acyrthosiphom gossypii under feeding stress. Under the stress of different population densities of A.gossypii, Ac.gossypii had no differences selection between healthy cotton and stressed cotton, which indicated that the Ac.gossypii could adapt to the cotton that was damaged by A.gossypii. Significant differences were observed in the selection of A.gossypii between healthy plants and cotton that was stressed by high densities A.gossypii and Ac.gossypii. The higher the stress densities were, the more obvious the difference of selection would be. With the prolongation of the feeding time of Ac.gossypii, there were no differences in the selection of Ac.gossypii to feeding stressed cotton for short time, but significant differences appeared to the stressed cotton for 3 to 5 days, while the selections of A.gossypii were significantly different to stressed cotton for 5 days. There was no significant difference in host selectivity of cotton with different degree of injury to cotton aphid (Aphis gossypii) in late stage stressed by A.gossypii for different time.【Conclusion】 Aphids of cotton prefer to choose healthy plants for feeding, which are easy to cause field diffusion, thus resulting in cotton victimization. The Ac.gossypii can adapt to cotton damaged by A.gossypii and coexist with A.gossypii in the field for a long time.
