The endosymbionts in BPH are rich in species. Among them, the primary fungal endosymbionts namely yeast-like symbiotes and two groups of bacterial endosymbionts Wolbachia and Arsenophonus were focused at present. Traditional methods for isolation and identification of BPH endosymbionts mainly include in vitro culture technique, cloning library construction and PCR-denaturing gradient gel electrophoresis. Recently, the depth of research on BPH endosymbiont diversity was greatly expanded by the application of metagenomics and highthroughput sequencing technologies. Endosymbionts are not only involved in host nutritional metabolism and hence provide essential nutrients, such as amino acids, vitamins and sterols for host growth, development and reproduction, but also mediate many physiological processes including virulence variation, insecticide resistance and pathogen defense. In view of the key roles that endosymbionts play in host growth, development and environmental adaptation, the endosymbiont-based biocontrol strategies for BPH have drawn much attention in recent years and shown a promising prospect for application. This review first gave a brief description of the main species and their biological characteristics of BPH endosymbionts, and then summarized the techniques used for the isolation, identification and diversity analysis of endosymbionts. Next, the biological functions of endosymbionts performed in BPH were systematically reviewed. Finally, the application potentials of endosymbionts in the biocontrol of BPH as well as the exsiting problems and future perspects were discussed. keywords:Nilaparvata lugens  endosymbiont  diversity  biological function  biocontrol View Full Text  View/Add Comment  Download reader
