Relationship of <i>Rice stripe virus</i> (RSV) acquisition rate between autumn and next spring population of small brown planthopper, <i>Laodelphax striatellus</i> (Fallén) in the field

Abstract

Rice stripe disease is a serious problem in rice cultivation in Japan. We investigated rice stripe virus (RSV) acquisitions on small brown planthoppers, Laodelphax striatellus (Fallén), collected in autumn and the following spring in Hyogo prefecture from 2013 to 2019. We performed a correlative analysis of acquisition rates in autumn and the next spring. The correlation of linear expression was indicated (y = 0.5402 x + 0.7760, p < 0.001) (y: next spring, x: autumn). This prediction method may lead to more effective plant protection techniques for farmers.
