Abstract
Rice stripe virus (RSV) causes chlorotic stripes, mottling, and necrotic streaks on rice leaves (Oryza sativa), resulting in a loss of production. RSV disease mainly occurs in Asian countries, including Taiwan, Japan, Korea, and China. In Japan, the disease devastated rice production from 1960 to 1985, and subsided thereafter owing to the introduction of new varieties resistant to RSV. However, its incidence has begun to increase again since 2004. Its vector, small brown plant hopper (Laodelphax striatellus, SBPH) persistently transmit RSV, and transmitted it from female adults to their progeny via egg. In this presentation, the molecular characteristics of transovarial transmission of RSV in SBPH are introduced. Countermeasures including adjusted timing of pesticide application and use of resistant varieties are discussed.
