Study on structure and diversity of moths communities under light-trap in the central and western Jilin province
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.
