The chromosome-level genome of Sitobion miscanthi, the dominant wheat pest in China, from a parthenogenetic female aphid colony was successfully assembled and further analyzed. The progress makes S. miscanthi an ideal model for studying host specificity, phenotypic plasticity, and interactions between aphid and various trophic levels and may drive an application breakthrough of aphid control. Yielded new insights into the mechanism of baculovirus infection in insects. It is for the first time confirmed that baculovirus infection caused reorganization of the nucleoli and redistribution of nucleolar components, which favor viral replication in infected cells. Revealed the molecular mechanism of seasonal breeding in Brandt’s vole. The close relationship between the expression of hypothalamic genes and seasonal breeding in wild rodent was firstly verified. The molecular mechanism of age-dependent reproductive strategy in Brandt’s vole was also reported. These results will promote further research on antifertility control for pest rodents. Completed the genome sequence analysis of the whitespotted flower chafer (Protaetia brevitarsis). The study provided the first report of the genomic characteristics of P. brevitarsis and therefore has important theoretical significance and application value in revealing the adaptive evolution mechanism of its feeding habits, strengthening control of the Scarabaeidae insects.

The larva and the adult of white-spotted flower chafer (Protaetia brevitarsis
