摘要
对幼龄茶园、丰产茶园、母穗园和自然生长的品种标本园中的昆虫群落进行了一年2月1次的调查分析。结果表明:害虫种数和个体数在4类茶园中均以中层居多,其中母穗园和标本园的害虫种数占全株7成;天敌的种数和个体数在丰产茶园以上层居多,其它3类茶茶园以中层最多。,在水平分布上,害虫种类以朝北方位较多。害虫种数和个体数以茶丛内层多于外层;天敌的种数和个体数在丰产茶园以外层较多,其他3类则以内层较多。从上层东南向至下层西北向总个体数趋于增多。物种数以6和10月较多,12月或2月较少。群落多样性以标本园>母穗园>丰产茶园>幼龄茶园。
Insect communities in young tea gardens,high yield tea grardens,tea cutting gardens and tea specimen gardens were systematically investigated by the 2 month interval surveys in a year.The species and the individuals of pests mostly distributed in the middle layer of tea bushes in all tea gardens, especially,occupying 70% of the whole species and individuals in the cutting gardens and the specimen gardens.As for natural enemies,the species and the individuals mostly distributed in the upper layer of the bushes in the high yield gardens but mostly distributed in the middle layer of the bushes in the other three gardens.Horizontally,pest species mostly distributed in the north of the bushes,and the species and individuals mostly distributed inner the bushes.The natural enemy species and individuals mostly distributed outer the bushes in the high yield gardens but mostly distributed inner the bushes in the other three gardens.The toatl individuals increased from the upper layer of southeast towards the lower layer of northwest.Species reached the maximum in June and October and the minimum in December and February.The community diversities in the gardens sequenced as the specimen gardens >the cutting gardens >the high yield gardens>the young gardens.The community stabilities in the gardens sequenced as the specimen gardens >the cutting gardens>the young gardens>the high yield gardens.
