Symbiotic microorganisms are essential for the physiological processes of her-bivorous pests,including the pear lace bug Stephanitis nashi,which is known for causing extensive damage to garden plants and fruit trees due to its exceptional adaptability to diverse host plants.However,the specific functional effects of the microbiome on the adaptation of S.nashi to its host plants remains unclear.Here,we identified significant microbial changes in S.nashi on 2 different host plants,crabapple and cherry blossom,characterized by the differences in fungal diversity as well as bacterial and fungal com-munity structures,with abundant correlations between bacteria or fungi.Consistent with the microbiome changes,S.nashi that fed on cherry blossom demonstrated decreased metabolites and downregulated key metabolic pathways,such as the arginine and mitogen-activated protein kinase signaling pathway,which were crucial for host plant adaptation.Furthermore,correlation analysis unveiled numerous correlations between differential mi-croorganisms and differential metabolites,which were influenced by the interactions be-tween bacteria or fungi.These differential bacteria,fungi,and associated metabolites may modify the key metabolic pathways in S.nashi,aiding its adaptation to different host plants.These results provide valuable insights into the alteration in microbiome and func-tion of S.nashi adapted to different host plants,contributing to a better understanding of pest invasion and dispersal from a microbial perspective.
