摘　　要：为探明吉林省中西部地区蛾类昆虫的种类及组成,提供蛾类群落的多样性资料,本研究于2017年-2020年利用高空探照灯逐日诱集蛾类昆虫并分类,明确不同昆虫季节性种群动态,在此基础上对蛾类群落多样性进行分析。结果共采集、鉴定蛾类昆虫18科227种,优势科为夜蛾科,种数占比达到49.34%。按为害植物类别,可分为农业害虫、林业害虫、果树害虫、蔬菜害虫等。蛾类昆虫4月始见,7、8月群落丰富度最高,7月群落多样性最高,群落均匀性随时间变化不明显。明确了不同月份优势度指数较高的种类。7、8月的蛾类群落相似性高,4、10月与各月的相似性低。本研究结果可为此区域蛾类害虫的监测预警与综合治理提供基础理论依据。This study aimed to reveal moth species and composition in the central and western Jilin province,and provide background information about insect diversity and emergence period.The moths communities of Lepidoptera were investigated by vertical-pointing searchlight-traps from 2017 to 2020.The result showed that there were 227 moth species belonging to 18 families,Noctuidae was the main family,and the proportion of individual species was 49.34%.Based on plant type,these species were divided into agricultural pests,forest pests,fruit trees pests and vegetable pests.Moths appeared in April.The index of richness in July and August and diversity in July were relative higher than those in other months.The evenness index was not significantly correlated with season.The dominant species in different months were confirmed.The community similarity was very high between July and August,while those were very low among April,October and other months.This study provides theoretical basis for monitoring,predicting and comprehensive protection of moth pests in this area.
