苜蓿盲蝽属物种多样性及其优势种空间分布格局
Species Diversity of the Adelphocoris and Spatial Distribution Pattern of Dominant Species
摘要
Abstract
The Adelphocoris insects are an important component of insect diversity in temperate grass-lands and meadows.It is also one of the important pests in leguminous grasses.Tongliao City of Inner Mon-golia is an important ecological production area in the northern agricultural and pastoral transitional zone of China.At present,the species diversity and geographical distribution of the Adelphocoris in the natural grass-land of the city are unknown.From July to September 2021,five-point sampling method was used to investi-gate the alfalfa bug species distributed in 20 natural grassland plots in 8 administrative areas of the city,and the samples were collected by sweeping net method.The results showed that the natural grassland of Tongliao City consists of 7 species of the Adelphocoris,among which the A.fasciaticollis and the A.lineolatus were the dominant species.In all survey plots,the diversity of the Adelphocoris were generally higher in two sample plots of the Bayan Hushuo Town of Zhalute Banner and Xiedai Sumu of Horchin Left Banner,the diversity of the sample plot of Bayantala Sumu in Zhalute Banner was relatively low.Two dominant species were distributed in natural grasslands in various counties.The occurrence of the A.fasciaticollis increased from north to south,while the incidence of the A.lineolatus decreased from north to south.The above research results have provided a more systematic understanding of the species diversity of the Adelphocoris and geographical distribution of dominant species of this genus in the natural grasslands of Tongliao City,based on previous data,providing reference data for the management and control of local grassland bug pests.关键词
