摘要 [目的]为了明确玉米//甘蔗对玉米蚜、甘蔗绵蚜田间种群数量的控制作用。[方法] 对比分析玉米、甘蔗间作和单作模式下玉米蚜、甘蔗绵蚜及其主要天敌昆虫的组成和多样性,并通过逐步回归分析和典型相关分析研究了不同种植模式下蚜虫-天敌间相关性。[结果] 玉米//甘蔗对玉米蚜和甘蔗绵蚜的发生具有明显的控制作用,间作模式下蚜虫发生数量和峰值均低于单作模式;天敌亚群落物种多样性特征在不同地点间差异较大,不同种植模式间差异较小;间作田蚜虫及其主要天敌间的相关性高于单作田。[结论] 玉米//甘蔗影响了田间天敌昆虫群落结构,增强了害虫-天敌间相关性,可有效降低田间害虫密度,用于玉米蚜、甘蔗绵蚜的田间生态控制。

Abstract: [Purpose] The aim of this study was to confirm the control effect of corn-sugarcane intercropping on the aphids' population in farming fields.[Methods] A field trap was carried out in corn-sugarcane intercropping fields and monocropping fields. Firstly, the composition and diversity of aphids and their main natural enemies were compared between different sampling sites and different cropping types. Secondly, stepwise regression analysis and canonical correlation analysis were used to analyze the correlations between the aphid and its main natural enemies.[Results] Corn-sugarcane intercropping played an obvious role in field aphids controlling. The population abundances and peak values of Rhopalosiphum maidis and Ceratovacuna lanigera in the intercropping fields were lower than monoculture fields. The diversity features of main aphid natural enemy changed with sampling sites and cropping types. And the differences between sampling sites were larger than the differences between cropping types. The correlation of aphids and its main natural enemies in corn-sugarcane intercropping was higher than monocropping.[Conclusion] Corn-sugarcane intercropping changed the structure of insect community in the field and improved the correlation between aphids and its main natural enemies. And the corn-sugarcane intercropping could be an effective pest management method in the farming fields to control R. maidis and C. lanigera in Yunnan.
