摘　　要：在云南绿春县,采用网扫法调查了培育云南紫胶虫5年的天然次生林(样地Ⅰ)和培育3年(样地Ⅱ)、1年(样地Ⅲ)及未培育紫胶虫(样地Ⅳ)的人工林中的蝽类昆虫群落。共采集蝽类昆虫423头,隶属于7科,47种。4个样地蝽类昆虫群落的物种组成和多样性各不相同。天然次生林蝽类物种组成丰富,条棘缘蝽占有较突出优势而导致多样性不高;人工林中,样地IV蝽类物种最丰富,优势度最低,均匀度和多样性最高;样地III次之;样地II物种最贫乏,优势度最高,均匀度和多样性最低。可见,紫胶虫与其栖境内蝽类的竞争将导致蝽类昆虫群落物种丰富度及多样性下降。The bug communities in a secondary forest having cultivated Kerria yunannensis for five years （plot Ⅰ）, and in the plantations having cultivated K. yunannensis for three years （plot Ⅱ） , one year （plot Ⅲ） , and zero year （plot Ⅳ）in Liiehun County of Yunnan Province were investigated by sweep netting method. A total of 423 specimens were collected, representing 47 species in 7 families of Heteroptera. The species composition and diversity of the bug communities differed with the plots. In plot I, the species richness was higher, while the diversity was moderate because of the more Cletomorpha insignis individuals. Among the plantations, plot Ⅳ was richest in species, lowest in dominance, and highest in evenness and diversity, followed by plot Ⅲ, and plot Ⅱ. With the increasing year of K. yunannensis cultivation, the species richness and diversity of bug communities tended to decrease because of their competition with lac insects.
