Resources And Diversity Of Lepidoptera In Dongsheng Wetland In Baoqing

Objective: to provide theoretical basis for studying the composition of Lepidoptera insects in Dongsheng wetland of Baoqing,we should attach importance to the awareness of protecting wetland environment,so we need more detailed investigation and investigation about Lepidoptera insects and their diversity.Methods: the traditional acquisition methods of Lepidoptera field investigation,mainly during the day by net sweeping,yellow disc,point trap and trap method,at night to black light trap method,collection of Lepidoptera in different periods,investigation and research,the collection of data processing software for diversity,diversity analysis and similarity.Results: the species of Lepidoptera in Dongsheng wetland in Baoqing are more abundant,and there are less and less rain weather,and there are 18 families,92 genera and 117 species.The diversity of species of insect in Lepidoptera and sampling of the wetland and Dongsheng geographical location,topography and climate conditions directly related to.From the analysis of the composition of the moth subjects: Noctuidae species total species is up to 42.25%,arctiidae,Geometridae species of the second,accounting for 11.27% of the total species,Phoenix moth and moss moth species at least.According to the classification level of the subordinate,the nocturnal moth family is the most,the moss moth and the Phoenix moth are the least.From the analysis of the composition of the butterfly families: Nymphalidae species are the most,accounting for 26.09% of the total species,second Satyridae species,accounting for 23.91% of the total species,and parnassiidae species at least,only 2.17% of the total species.Analysis on the classification level of subordination: Satyridae> Lycaenidae > Nymphalidae?Pieridae > Papilionidae,Hesperiidae > Parnassiidae,which accounted for 10.87% of total genera satyridae.Conclusion: after sorting and identification,117 species of Lepidoptera were observed or captured,including 21 dominant species,belonging to 18 families and 92 genera.
