Composition of Aphid Community in Potato Field in Siziwang Banner,Inner Mongolia Autonomous Region
Potato production in China is often affected by viral diseases,and aphids are important vectors for the transmission of potato viral diseases.From July to August 2021 and 2022,aphids in potato fields were collected in Siziwang Banner,Wulanchabu City,Inner Mongolia Autonomous Region using yellow trap and yellow plate,and the species identification and community structure analysis of the collected samples were carried out.Eighteen genera and 24 species of aphids in the local potato fields were identified.Among them,Hyalopterus pruni,Aphis gossypii,Myzus persicae,A.craccivora,Acyrthosiphon kondoi,Macropodaphis paradoxa,Sitobion miscanthi and Rhopalosiphum padi were the dominant species.According to the analysis of the diversity index,richness index and evenness index of the aphid community,the relative number of dominant populations changed little with time,which indicates that the composition of the aphid community in the potato field in this region is relatively stable.The experimental results would lay a research foundation for the monitor and control of aphids in local potato fields.
