中文摘要:

2018年5-10月在河南鸡公山国家级自然保护区内开展了昆虫多样性调查工作，共采集到昆虫2 110头，分别隶属于15目106科880种。其中以鳞翅目Lepidoptera（274种）、鞘翅目Coleoptera（206种）、半翅目Hemiptera（185种）和膜翅目Hymenoptera（89种）为主，种数占比分别为31.14%、23.41%、21.02%和10.11%，其他类群（共126种）占14.32%。9种不同植被类型中昆虫群落多样性分析结果表明：针阔混交林、阔叶混交林、灌草丛和马尾松林中昆虫群落多样性的各项指标均较高，落羽杉林和杉木林次之，草甸、水生植被和竹林最低。在区系组成上，古北种昆虫最丰富，有372种，占总数的42.26%；其次是东洋种，有269种，占30.57%；广布种最少，有239种，占27.15%。在昆虫群落相似性方面，总体上两种混交林与其他森林类型的相似性较高，而竹林、草甸和水生植被与其他森林类型的相似性较低。

英文摘要:

Systematic investigation was conducted to study the diversity of insect in the Jigongshan National Nature Reserve, Henan Province, from May to October, in 2018. A total of 2 110 specimens belonging to 106 families, 15 orders and 880 species were collected. The results of species group analysis showed that Lepidoptera (274 species), Coleoptera (206 species)，Hemiptera (185 species)and Hymenoptera (89 species)were the dominant groups in the reserve, accounting for 31.14%, 23.41%, 21.02% and 10.11% of the total species, respectively. Other groups (126 species)accounted for 14.32%. In addition, the index of diversity of whole insect community, such as richness, abundance, diversity, and evenness, were much higher in the mixed coniferous broad leaved forest, broad leaved mixed forest, shrub grassland and Pinus massoniana forest than Taxodium distichum forest and Cunninghamia lanceolata forest. The results of faunal composition analysis showed that the richest insects in the reserve were Palaearctic species (372 species, accounted for 42.26%), followed by Oriental species (269 species, accounted for 30.57%), while widespread species were the least (239 species, accounted for 27.15%). Similarities of insect community were higher between two kinds of mixed forest and the others, but they were lower between bamboo forest, meadow, aquatic vegetation and the others.
