摘　　要：为探明吉林省中西部地区大豆蛾类害虫的群落组成及多样性,以对此类害虫进行监测预警及综合治理,本研究于2017—2020年利用高空探照灯逐日诱集蛾类昆虫并分类,分析虫源、危害方式,阐明种群动态,并在此基础上对大豆蛾类害虫群落多样性进行研究。结果表明:(1)共采集、鉴定大豆蛾类害虫7科18种,优势科为夜蛾科,种数占比达到50%。虫群来源包括本地越冬、单纯迁入、本地越冬结合迁入。按危害方式划分为地下害虫、钻蛀害虫、食叶害虫。明确了11个种群中数量大、可造成危害的关键害虫的种群动态。(2)蛾类群落丰富度随时间呈现波浪式变化,5月和10月的蛾类群落丰富度相对较低,8月群落多样性相对较高,均匀度随时间变化不明显。5月和6月的群落相似性高,10月与各月的相似性系数都较低。明确了各月份优势度指数较高的种类。本研究结果提供了吉林省中西部地区详尽的大豆蛾类害虫群落结构资料。In order to explore the community composition and diversity of soybean moth pests in the central and western regions of Jilin Province,to monitor,early warning and comprehensive management of these pests,we investigated the moths communities of Lepidoptera by vertical-pointing searchlight-traps from 2017 to 2020 to reveal the composition,population source,harm way,population dynamics and community diversity.The results showed as follows:(1)There were 18 soybean moth species belonging to 7 families,Noctuidae was the main family,and the proportion of individual species was 50%.Population source consisted of overwintering,migration,overwintering and migration.Based on harm way,these species were divided into underground,borer and leaf-eating pests.The population dynamics of most abundant eleven species were analyzed.(2)The varied richness exhibited a discreet picking phenomenon.The index of richness in May and October were relative higher,while index of community diversity in August was relative higher than other moths.The evenness index was not significantly correlated with season.The community similarity was very high between May and June,while those were very low between October and other moths.The dominant species in different moths were confirmed.In conclusion,this study provides theoretical basis for community structure of soybean moth pests in the central and western regions of Jilin Province.
