摘要: The adults of Monolepta signata mainly feed on corn silks, anther and kernels at the filling stage, which result in great loss of yield and quality. Herein, we studied the population genetics and demographic history of M. signata based on mitochondrial genes (COI) and nuclear genes (ITS2, EF-1α). Based on the data of environmental factors and known sample points, the fitness of M. signata was also analyzed according to mathematical statistics and ecological niche theory. The distribution of the suitable habitat of M. signata in China and center-of-mass transfer under different climatic scenarios in the present and future time periods were predicted. The areas of potential serious damage in the future were also predicted. The population of M. signata has also experienced rapid expansion. The damage caused by M. signata in Xinjiang will be worse and more attention should be paid on.
