摘　　要：[目的]研究桉树黑球蚜的发生规律及相关影响因素。[方法]对桉树黑球蚜危害样地进行调查与分析。[结果]桉树蚜虫虫口密度与昆虫多样性指数及均匀度指数呈负相关,与虫害指数呈正相关;相同时间段桉树枝瘿姬小蜂个体数远远大于桉树黑球蚜;与雨量相比,温度因素对黑球蚜的发生影响更大。[结论]结果为广西地区桉树黑球蚜的科学防治提供理论参考。[Objective]To study the occurrence and related factors of eucalyptus aphides.[Method]The damage sample plots of eucalyptus aphides were investigated and analyzed.[Result]The population density of eucalyptus aphides had a positive correlation with the pest index,and had a negative correlation with the insect diversity index and evenness index.The individuals number of Leptocybe invasa was much larger than that of eucalyptus aphides at the same stage.The temperature factor had more influence on the occurrence of eucalyptus aphides compared with the rainfall factor.[Conclusion]The results provide theoretical reference for the scientific control of eucalyptus aphides in Guangxi.
