摘　　要：为了解混播草坪昆虫群落组成及优势种群动态,为草坪害虫的防治及天敌昆虫的保护利用提供依据,本试验以贵阳混播草坪为研究对象,研究了草坪昆虫群落组成及优势种群动态。结果表明,贵阳混播草坪的昆虫群落由11目63科104种构成,主要类群为直翅目、半翅目、鞘翅目、革翅目、鳞翅目、膜翅目和双翅目,个体数量占98.7%,其中有92种害虫、10种益虫和2种中性昆虫。草坪昆虫群落表现出明显的季节动态,物种丰富度在7月达到最高,种数达33种;主要优势种害虫有蝗虫(Oxya chinensis)、中华螽斯(Tettigonia chinensis)、绿盲蝽(Apolygus lucorum)、盲蝽、蚜虫、沫蝉、灰飞虱(Laodelphax striatellus)和叩甲,以及天敌昆虫异色瓢虫(Harmonia axyridis P.)和多异瓢虫(Adonia variegata G.),两种天敌昆虫对蚜虫有明显的跟随效应。This study explored the insect community composition and dynamics of dominant populations in mixed lawns in Guiyang City,which was aimed to provide references for pest control and protection and utilization of natural enemy insects.The resutls indicated that the insect community structure in the mixed laws was composed of 104 species from 63 families,11 orders.The main groups were Orthoptera,Hemiptera,Coleoptera,Dermoptera,Lepidoptera,Hymenoptera and Diptera,which accounted for 98.7%.Of the observed insects,92 species were classified as pests,10 species were beneficial insects and 2 species were neutral insects.The species richness of the insect community reached the maximum in July,and 33 species were observed which constituted of Oxya chinensis,Tettigonia chinensis,Apolygus lucorum,Miridae,aphis,Cercopidae,Laodelphax striatellus and click beetle,as well as natural enemy insects Harmonia axyridis and Adonia variegata G.Moreover,the two natural enemy insects had obvious following effects on aphids.
