水稻齿叶矮缩病(RRSV)于1976年在印度尼西亚首次发现。尔后在东南亚稻区迅速蔓延。我国福建省于1978年首见发病,以后在广东、湖南、江西与浙江等省相继发生。该病主要由迁飞性害虫褐稻虱传播,本省早稻田虫源主要来自南亚稻区。为了探明该病在本省稻苗上的潜育期及介体虫褐稻虱的传毒特性,以便为防治提供依据,我们于1986年进行了试验观察。
Rice leaf deciduous disease (RRSV) was first detected in Indonesia in 1976. Afterwards, it spread rapidly in Southeast Asia. Fujian Province in China, the first sight of the disease in 1978, later in Guangdong, Hunan, Jiangxi and Zhejiang provinces have occurred. The disease is mainly transmitted by the migratory pests, brown planthopper, and the source of the early rice fields in the province mainly comes from the South Asia rice area. In order to ascertain the latent period of the disease on the rice seedlings in the province and the transmission characteristics of the mediator B. lupulus in order to provide the basis for prevention and treatment, we conducted the experimental observation in 1986.
