中文摘要：
为探讨间作对于茶园昆虫群落多样性和群落结构的影响,遂于皖南山区石台县选苦李-茶、山茱萸-茶、板栗-茶间作茶园,邻近每类间作茶园、选择相同品种和同样立地条件的纯茶园作为对照,2007年1月-2009年1月,每月上旬调查这6块茶园昆虫、蜘蛛和捕食螨种数和个体数。结果表明：①与对照茶园相比,间作茶园昆虫的总物种数、总多样性指数稍大,间作茶园的天敌个体数稍多、益害生物的个体数量比值稍大;②间作对茶园昆虫的总个体数有影响。结果表明茶园间作可在一定程度上增加昆虫多样性。
英文摘要：
The effects of intercropping on insect community diversity and community structure were investigated in plantations of Chinese plum-tea,medical dogwood-tea or chestnut-tea.Within 6 intercropped plantations,the richness and abundance of insects,araneids and mites were investigated at monthly intervals from January 2007 to January 2009.The results show that： ① total species richness and diversity indices were markedly greater in intercropped plantations compared to the control plantation,and the abundance of natural enemies of plant pests and the ratio of beneficial to harmful organisms was slightly larger.② the effect of intercropping on total abundance was not obvious.We conclude that intercropping increases insect diversity in tea plantations to some extent.
