An investigation was made on the insect community composition and structure in a Zanthoxylum bungeanum garden with corn-soybean - Z. bungeanum intercropping, soybean - Z. bungeanum intercropping, corn - Z. bungeanum intercropping, and only Z. bungeanum planting in Zhaotong City of Yunnan Province, and the community character index and principal component analysis were used to study the characters and stability of the insect community. A total of 326 insect species were recorded. In intercropped plots, the abundance, diversity, and evenness index of insect community were higher while the dominance index was lower, compared with those in monocultured Z. bungeanum plot. The diversity index of insect community decreased in the order of corn-soybean- Z. bungeanum intercropping > soybean - Z. bungeanum intercropping > corn - Z. bungeanum intercropping > only Z. bungeanum planting, and the insect community in corn-soybean - Z. bungeanum intercropping plot was relatively stable.
对云南省昭通市花椒园中玉米 - 大豆 - 花椒间作、大豆 - 花椒间作、玉米 - 花椒间作以及单种花椒的昆虫群落组成和结构进行了调查，并采用群落特征指数和主成分分析方法研究昆虫群落的特征和稳定性。共记录到326种昆虫。与单种花椒地块相比，间作地块昆虫群落的丰富度、多样性和均匀度指数较高，优势度指数较低。昆虫群落多样性指数大小顺序为玉米 - 大豆 - 花椒间作＞大豆 - 花椒间作＞玉米 - 花椒间作＞单种花椒，玉米 - 大豆 - 花椒间作地块的昆虫群落相对稳定。
