Assessing the local adaptative changes associated with range expansion of the pink stem borer

Understanding the genetic basis of adaptive evolution following habitat expansion can have important implications for pest management. The pink stem borer (PSB), Sesamia inferens (Walker), is a destructive pest of rice that historically restricted to regions south of N34° latitude in China. However, with changes in global climate and farming practices, the distribution of this moth has progressively exceeded its traditional limit of 34° N and encompassed most regions in North China. However, the evolutionary processes and local adaptative changes of this species, are not yet fully understood. Here, we employed genome resequencing to genotype over 1 million of high‐quality SNPs and 20,000 SVs from 14 geographical populations across China. Three highly differentiated genetic groups were formed, corresponding to Northern, Southern China regions and Yunnan-Guizhou Plateau. The pairwise genetic distance between locations was highly correlated with geographic and environmental distance.
