摘      要：Understanding the genetic basis of adaptive evolution following habitat expan-sion can have important implications for pest *** pink rice borer(PRB),Sesamia inferens(Walker),is a destructive pest of rice that was historically restricted to regions south of 34o N latitude in ***,with changes in global climate and farming practices,the distribution of this moth has progressively expanded,en-compassing most regions in North ***,3 highly differentiated subpopulations were discovered using high-quality single-nucleotide polymorphism and structural vari-ant datasets across China,corresponding to northern,southern China regions,and the Yunnan-Guizhou Plateau,with significant patterns of isolation by geographic and envi-ronmental *** estimates of evolutionary history indicate asymmetric migration with varying population sizes across the 3 *** sweep analyses esti-mated strong selection at insect cuticle glycine-rich cuticular protein genes which are as-sociated with enhanced desiccation adaptability in the northern group,and at the histone-lysine-N-methyltransferase gene associated with range expansion and local adaptation in the Shandong *** findings have significant implications for the development of effective strategies to control this pest.
