Abstract:  Rice stripe virus（RSV） is an important virus transferred by small brown planthopper， Laodelphax striatellus， and causes tremendous loss on rice production in China. Himetobi P virus （HiPV） belongs to the genus Cripavirus in the family Dicistroviridae and has non\|lethal effects on L.striatellus. In the present study， homology analysis indicated that different HiPV isolates shared high similarity， whereas low conservation were observed for HiPV with other viruses in genus Cripavirus. Detection of RSV and HiPV in rice suggested that RSV could replicate in rice， while HiPV cannot （though HiPV could exist in rice stably for approximately 7 days）. Further experiment confirmed the accumulated HiPV in faeces of L.striatellus， but not RSV.
