云南广南油茶园节肢动物群落组成和多样性特征

摘要

The composition and diversity of arthropod community were investigated using traditional methods in Ca-mellia oleifera garden in Guangnan County of Yunnan from March to April and from August to September 2013. The results shows that 58 species of insects belongs to 12 orders 44 families, 4 species of Araneae belongs to 3 fami-lies and 1 species of Acariformes belongs to 1 family.The Simpson index, Shannon index and Eveness index from March to April was 0.447 7, 1.126 2, 0.710 5 respectively, and 0.707 5、 2.820 2 and 0.663 9 from August to September.The species and their abundances showed a trend of rise according to the log ( x+1) value in Camellia oleifera garden in Guangnan County of Yunnan from March-April 2013 to August-September 2013.%以云南广南传统油茶品种普通油茶园为调查地，于2013年3－4月（油茶生长期）和8－9月（油茶花、果期）采用传统方法进行调查，分析油茶园节肢动物群落组成及其多样性特征。结果表明，昆虫群落58种隶属于12目44科，蜘蛛目3科4种，真螨目1科1种。3－4月节肢动物群落Simpson指数、 Shannon指数和均匀度指数分别为0．4477、1．1262、0．7105；8－9月节肢动物群落Simpson指数、 Shannon指数和均匀度指数分别为0．7075、2．8202、0．6639。 log （x＋1）值的节肢动物群落动态表明，广南油茶园节肢动物群落物种及其数量均呈升高趋势。研究结果对于探讨油茶园节肢动物群落的功能及其在油茶害虫综合治理中的作用具有参考价值。
