黑尾叶蝉Nephotettix cincticeps Uhler是我国长江流域稻区的主要害虫之一,作为病毒及类菌原体病原的介体,传播水稻矮缩病、黄矮病和黄萎病所造成的损失,远比吸汁为害严重。为了更有效地控制其为害,我们先后在浙江省4个县具有代表性的地区为研究基点,进行黑尾叶蝉传染水稻病毒病的研究。本文着重讨论黑尾叶蝉作为传病介体,在稻田的种群动态与病毒病的关系,及其化学防治。 Nephotettix cincticeps Uhler is one of the major pests in the rice area of ​​the Yangtze River valley in China. As a mediator of viruses and mycoplasmas, the spread of rice dwarf, yellow dwarf and Verticillium wilt is far behind. Serious than the suction juice. In order to control its damage more effectively, we conducted research on the infection of rice virus with rice leafhoppers in the representative areas of 4 counties in Zhejiang Province. This article focuses on the relationship between the population dynamics and viral diseases of rice leafhopper as a disease mediator and its chemical control.
