摘要
广西南宁市郊稻田害虫和捕食性节肢动物群落,由46科159种组成,其中害虫21科65种;捕食性昆虫12科39种;蜘蛛13科55种。早、晚稻构成群落的物种基本相似,但各物种的数量结构及优势种差异明显。文中分析了晚稻害虫、捕食性昆虫和蜘蛛亚群落的垂直分层、时空格局及其数量变动的原因。
The pest and predacious arthropod community in paddy field in Nan-ning includes 39 families 159 species, of which pest was 21 families 65 species predacious insect 12 families 39 species and spider 13 families 55 species. Species in early rice field and late rice field communities were basically similiar,but dominant species and its numerical structures are significantly different. The cause of dynamics and changes of vertical distribution,time-space and numerical structures of three subcommunities were also discussed in this paper.
