小麦丛矮病是由灰飞虱(Laodelphax striatellus Fallen)传播的病毒性病害。一年中,秋季和春季是小麦丛矮病发生的主要时期。此时传毒介体灰飞虱的传毒能力决定于介体本身因素及环境因素。为弄清灰飞虱的介体传毒和病害发生间的诸关系,在1979—1980年的秋、春季节,进行小麦丛矮病传毒介体的传毒效力研究,进而给小麦丛矮病的病害流行因素、预测预报工作及控制病害发生提供线索及依据。 Bushy dwarf disease is a viral disease transmitted by Laodelphax striatellus Fallen. During the year, autumn and spring are the major periods of wheat dwarf disease. At this point, the virus-transmitting vector Laodelphaxaphylaxis is determined by the mediator itself and environmental factors. In order to understand the relationship between Laodelphax striatellus infection and disease occurrence, in the autumn and spring seasons from 1979 to 1980, the virulence of the virulence promoter of wheat bushy dwarf virus was studied, Disease epidemic factors, forecast and forecasting work to provide clues and basis for disease control.
