采用水稻条纹病毒(rice stripe virus,RSV)接种可使水稻产生卷叶型和展叶型2种症状.4个粳稻品种,在三叶期接种多呈卷叶型,在幼穗分化期接种多呈展叶型;4个籼稻品种,在三叶期接种多呈展叶型,在幼穗分化期接种均为展叶型.灰飞虱(Laodelphaxstriatellus)对 RSV 的获毒个体率为25%—30%,高者可达50%以上;其传病能力与获毒取食和接种取食时间的长短有关.灰飞虱的传毒力因产地、翅型、性别和虫期而异. Inoculation with rice stripe virus (RSV) resulted in two kinds of symptoms, ie, rollover and leaf unfolding of rice, and the four japonica cultivars were mostly inoculation at the three-leaf stage and inoculation at the young panicle stage Four indica rice varieties were inoculated at the three-leaf stage and were leaf-foliar inoculation at the young spike differentiation stage, with the leaf-spreading type of Laodelphax striatellus being 25% 30%, the highest can reach more than 50%; its ability to get rid of the poisoning and feeding and feeding the length of time related to Laodelphae virility due to origin, wing type, sex and worm stage vary.
