【摘要】 对皖南丘陵品种园内临海藤茶、福鼎大白茶、祁门 ９ 号、佛手、福建大毫、圆叶种、广东凤凰单丛 １ 号和皖农６０ 号上节肢动物群落，一年内两月１ 次的调查，发现１４ 目、３９ 科共１４０ 种昆虫、蜘蛛、捕食螨及其它节肢动物，约占全省茶园中的已记录种数的１７％ 。品种间，节肢动物群落的组成有相似性，优势目相同；植食昆虫种数≥５０％ 、个体数接近或大于８０％ 。但植食昆虫个体数、益害物种数比（ Ｎｓ／ Ｐｓ）、益害个体数比（ Ｎｎ／ Ｐｎ）有差异；物种数、个体数、多样性指数 Ｈ、均匀度指数、优势度指数、 Ｎｎ／ Ｐｓ 和 Ｎｎ／ Ｐｎ 的差异未达显著水平； Ｈ的波动趋势不同。更多还原

【Abstract】 The arthropoda communities on 8 tea varieties, namely Linghaitengcha, Fudingdabaicha, Qimen 9, Foshou, Fujiandahao, Yuanyezhong, Guangdongfenghuangdangcong 1 and Wannong 60, within a tea specimen garden in Wannan hilly tea region were systematically investigated by the 2 month interval surveys in a year. 140 species of insects, spiders, predatory mites and other arthropodas, belonging to 39 families of 14 orders and occupying about 17% of total arthropoda species number recorded in Anhui tea region, were found out. This result proved tea specimen was importance of protection. There are similarity of components of arthropoda communities among tea varieties. The dominant groups were Homoptera, Hymenoptera, Arancida, Diptera and Lepidoptera. The species number of phytophagous insects ≥50% and their individuals were near to or over 80%. However, among tea varieties, there existed differences on phytophagous insects, ratio of natural enemy to pest species number (Ns/Ps) and ratio of natural enemy to pest individual number (Nn/Pn). The differences of species number, individual number, indexes of diversity H, indexes of eveness, indexes of dominance, Ns/Ps and Nn/Pn within varieties did not reach significant level. And the fluctuation tendency of Hdiffered in varieties.更多还原
