[目的]探明河北小五台自然保护区的蝽类物种及其组成情况.[方法] 2009年在河北小五台山选取5条不同样带,对半翅目昆虫群落组成和多样性进行研究.[结果]共采集标本3 246只,隶属于21科98属145种,其中蝽科最多,占43.31％；蝽科、缘蝽科、同蝽科、姬缘蝽科和盲蝽科共同构成该地区的优势类群,这5个科的个体数量占总采集数量的76.59％.半翅目群落种-多度关系接近于正态分布模型.涿鹿杨家坪的物种多样性指数、物种数和个体数量最高；蔚县王喜洞的物种多样性指数、物种数和个体数量最低.聚类分析结果表明蔚县小五台、蔚县山涧口和蔚县王喜洞半翅目昆虫群落相似度较高,蔚县金河口和涿鹿杨家坪的相似度较高.[结论]该研究为自然保护区昆虫种质资源的保护提供参考.%[ Objective] To discuss the species and composition of Hemiptera in Mt. Xiaowutaishan national nature reserve, Hebei. [ Method] The community structure and species diversity of Heminptera in five sample belts were surveyed from June to August in 2009. [ Result] A total of 3 246 individuals were collected, belonging to 21 families, 98 genera and 145 species of Hemiptera. The individual of Pentatomidae was the maximum, accounting for 43. 31% , the individuals of Coreidae, Acanthosomatidae, Rhopalidae and Miridae were richer than other families. These five families were considered as dominant groups, accounting for 76.59% of the total collected quantity. The curve of the species-abundance of Hemiptera was in accordance with the normal distribution model. Among the five sample belts including Xiaowutai in Wei County (XWTW) , Jinhekou in Wei County (JHKW) , Wangxidong in Wei County (WXDW) , Shanjiankou in Wei County (SJKW) and Yangjiaping in zhuolu County (YJPZ) , the individuals, species abundance and Shannon diversity were the highest in the YJPZ belt, but the lowest in the WXDW belts. Cluster analysis showed that the composition diversity of Hemiptera and habitats were similar among WXDW belt, WXDW belt and SJKW belt, it was similar between JHKW belt and TJPZ belt as well. [ Conclusion] The research provided reference for the protection of insect germplasm resources in the nature reserve.
