摘要
为探明吉林省中西部地区玉米蛾类害虫的种类及组成,2017~2020年利用高空探照灯逐日诱集蛾类昆虫并分类,阐明各蛾类种群的动态,对蛾类群落多样性进行分析。结果表明,共采集、鉴定玉米蛾类害虫4科16种,优势科为夜蛾科,种数占比达68.75%。明确各种害虫的虫源结构及危害方式,分析9种种群数量大、可造成危害的关键害虫的种群动态。蛾类群落丰富度随时间的变化呈波浪式,7月的群落丰富度、群落多样性都较高,5月、10月的群落均匀度相对较高。5月、7月的群落相似性系数最高,10月与各月的相似性系数都较低。明确各月优势度指数较高的种类,可为此区域蛾类害虫的监测预警与综合治理提供理论依据。
The moth communities of Lepidoptera were investigated by vertical-pointing searchlight-traps from 2017 to 2020 to reveal the maize pests and composition in the central and western Jilin province,and provide background information about insect diversity and population dynamics.The results showed that,there were 16 maize moth species belonging to 4 families,the dominant family is the Noctuidae,with 68.75%of individual species.The population source and harm way of these moths were analyzed,and the population dynamics of abundant nine species were analyzed.The varied richness exhibited a discreet picking phenomenon.The index of richness and diversity in July was relatively higher than other months.The index of evenness in May and October was relatively higher.The community similarity was very high between May and July,while those were very low between October and other months.The dominant species in different months were confirmed.This study provides a theoretical basis for monitoring,predicting and comprehensive protection of maize pests in this area.
