초록

Aphis gossypii is considered as one of the most polyphagous aphid species and found throughout the world. This pestinduce plant deformation and transmit viruses by feeding the host plant. In Korea, A. gossypii has been occurred in manycrops, however, the population genetic structure of this pest has not been revealed. In this study, we used eight microsatellitemarkers to analysis the population genetic structure of A. gossypii in Korea. We collected A. gossypii specimens frompepper greenhouse in 2016 (18 sites) and 2017(15 sites). As a result, two genetic cluster (△K=2) showed in structureanalysis. As we compared the cluster result between 2016 and 2017, several populations appeared opposite clustering groupeven the samples were collected in same site and crop. Therefore, more samples are required from different greenhouse(same host) to identify the accurate genetic cluster of province in Korea. From this study, the genetic variation revealedfrom A. gossypii and this information may develop sustainable management of A. gossypii.
