为阐明田埂杂草对多异瓢虫 Hippodamia variegata 的保育作用以及多异瓢虫对其趋性行为反应, 为棉田蚜虫等害虫的绿色防控奠定重要的理论基础, 本文采用种群系统调查法研究新疆棉区田埂3种常见豆科杂草(甘草 Glycyrrhiza uralensis、骆驼刺Alhagi camelorum、苦豆子Sophora alopecuroides)上多异瓢虫和棉黑蚜Aphis atrata 的种群动态并分析二者的相关性, 同时通过Y形嗅觉仪测试多异瓢虫雌雄成虫对3种豆科杂草不同处理的趋性行为反应。结果表明:5月下旬至6月下旬, 田埂3种豆科杂草上多异瓢虫成虫和幼虫的种群密度均较高, 最大值分别达1.35~2.80头/m2和0.93~1.80头/m2, 在这一时期每种豆科杂草上多异瓢虫的猎物棉黑蚜种群密度也较高; 在整个调查期间3种豆科杂草上多异瓢虫与棉黑蚜的种群密度均显著相关, 相关系数分别为0.923(甘草)、0.774(骆驼刺)、0.839(苦豆子)。同时, 多异瓢虫雌雄成虫对3种豆科杂草不同处理间的趋性选择反应相似, 均为棉黑蚜为害植株>棉黑蚜>健康植株>空白, 且多异瓢虫对棉黑蚜为害株的选择性均显著大于相应的健康株。因此, 新疆棉区田埂3种豆科杂草上的棉黑蚜对多异瓢虫早春种群具有重要的保育作用。 |

This study aimed to clarify the conservation effects of three leguminous weeds ( Glycyrrhiza uralensis, Alhagi camelorum, Sophora alopecuroides ) on Hippodamia variegata inhabiting on the ridge of cotton fields, and explore the behavioral responses of H. variegata to three leguminous weeds under different treatments, in order to lay an important theoretical foundation for the green prevention and control of aphids and other pests in cotton fields. The population dynamics of H. variegata and Aphis atrata on three leguminous weeds was studied through systematic survey. Meanwhile, the behavioral responses of female and male H. variegata adults to three leguminous weeds under different treatments were observed by using Y-tube olfactometer. The results showed that the population densities of H. variegata adults and larvae on three leguminous weeds were the highest from late-May to late-June, and the maximum densities reached 1.35-2.80 individuals and 0.93-1.80 individuals per square meter, respectively; the population densities of A. atrata was also higher during this periods. There was a significant correlation between the population densities of H. variegata and A. atrata on each leguminous weed during the whole investigation periods, and the correlation coefficients were 0.923 ( G. uralensis ), 0.774 ( A. camelorum ), 0.839 ( S. alopecuroides ), respectively. Behavioral responses of female and male H. variegata adults to three leguminous weeds under different treatments were all consistent, and the ranking was healthy plants damaged by A. atrata > A. atrata > healthy plants > blank. There were significant differences in selectivity for A. atrata between healthy and damaged plants for each leguminous weed. Therefore, A. atrata on three leguminous weeds in Xinjiang cotton fields plays an important conservation role for H. variegata during spring. |
