云南省西畴县蝽次目昆虫多样性研究

Diversity of Pentatomomorpha(Hemiptera:Heteroptera)in Xichou County of Yunnan Province

于2016年6月至2017年10月,对西畴县蝽次目昆虫进行调查,共采集蝽次目昆虫标本1234号,隶属于13科67属106种。其中优势类群为蝽科昆虫,有21属31种,其次是缘蝽科,有17属29种;优势种为瘤缘蝽和小皱蝽。多样性分析显示,Margalef物种丰富度以蝽科最高,其次为缘蝽科,以蛛缘蝽科、异蝽科、土蝽科和扁蝽科最低;Shannon多样性指数以蝽科最高,其次为盾蝽科,以蛛缘蝽科、异蝽科、土蝽科和扁蝽科最低;Pielou均匀度以同蝽科最高,其次为盾蝽科,以蛛缘蝽科、异蝽科、土蝽科和扁蝽科最低;Berger-parker优势度蛛缘蝽科、异蝽科、土蝽科和扁蝽科最高,其次为龟蝽科,蝽科最低;不同海拔和不同行政区蝽次目昆虫在物种、数量、优势种、多样性特征和相似性上均存在差异。结果表明,西畴县蝽次目昆虫具有较高的多样性,结构相对稳定;群落结构和多样性随海拔和不同乡镇呈现不同特点。

An investigation was carried out on the species of Pentatomomorpha in Xichou County,Yunnan Province from June 2016 to October 2017.A total of 1 234 pentatomomorpha specimens were collected,of witch 106 species belonging to 67 genera and 13 families were identified.Pentatomidae was the dominant family,with 31 species and 21geneera,and the second was Coreidae,with 29 species and 17 genera.The dominant species were Acanthocoris scaber Linnaeus and Cyclopelta parva Distant.Pentatomidae had the highest Margalef richness index,followed by Coreidae,and those with the lowest indexes were Alydidae,Urostylidae,Cydnidae and Aradoidea.Pentatomidae had the highest Shannon diversity index,followed by Scutelleridae,and the lowest ones were Alydidae,Urostylidae,Cydnidae,and Aradoidea.Acanthosomatidae had the highest of Pielou index,followed by Scutelleridae,and the lowest ones were Alydidae,Urostylidae,Cydnidae,and Aradoidea.Scutelleridae,and Alydidae and Urostylidae and Cydnidae and Aradoidea had the highest Berger-parker index,followed by Plataspidae,and Pentatomidae had the lowest. There were differences in species,quantity,dominant species,diversity and similarity of Pentatomoidea insect community from Xichou Couty in different altitudes and sites.The results showed that there were high diversity and stable structure of Pentatomoidea insect in Xichou Couty,with different characteristics in different towns and altitudes.
