中文摘要：

为研究邻作枇杷对花椒园昆虫群落和棉蚜的影响,以云南省昭通市永善县邻作枇杷的花椒园与花椒单作园为研究对象,调查了其昆虫群落组成和结构的周年变化及棉蚜种群动态,并采用群落特征参数等对昆虫群落稳定性、群落特征及动态进行比较分析.结果显示：邻作枇杷的花椒园采集到昆虫（包括蜘蛛）10目175种2 163头,单作花椒园采集到昆虫（包括蜘蛛）8目148种2 381头;与单作花椒园相比,邻作花椒园植食性物种数和个体数所占比例较低,捕食性天敌物种数、个体数所占比例较高,昆虫群落丰富度指数、多样性指数和均匀性指数较高,而优势集中性指数和优势度指数较低,棉蚜发生数量较低.可见,花椒-枇杷邻作对花椒主要害虫棉蚜有一定的控制作用.

英文摘要：

To make sure the effect of pepper （Zanthoxylum bungeanum） planted adjacent to loquat [ Eriobotrya japonica （Thunb.） L. ] on insect community and Aphis gossypii, the component and the structure dynamic of insect community and the A. gossypii population were studied in this research. With the character indices, the insect community and A. gossypii population were compared and ana- lyzed between loquat-pepper adjacent planting garden and pepper mono-planting garden in Yongshan County, Zhaotong City, Yunnan Province. The results showed that there were 2 163 insects （inclu- ding spiders） belonging to 10 orders and 175 species insects were found in loquat-pepper adjacent planting garden. There were 2 381 insects （including spiders） belonging to 8 orders and 148 species were found in pepper mono-planting garden. The proportion of the number of individual and species of phytophagy, the superiority concentric and dominance indices were lower in loquat-pepper adjacent planting garden than those in pepper mono-planting garden. Meanwhile, the number of A. gossypiipopulation was remarkably less in loquat-pepper adjacent planting garden than in pepper mono-planting garden. On the contrary, the proportion of the number of individual and species of predator, richness, diversity and evenness indices of insect community were higher in loquat-pepper adjacent planting garden than those in pepper mono-planting garden. Therefore, it can be concluded that pepper planted adjacent to loquat has definite inhibition effect on the numbers of A. gossypii.
