【摘要】 2009年以来,稻飞虱(白背飞虱和灰飞虱)的区域性暴发和它们传播的南方水稻黑条矮缩病(SRBSDV)的大面积流行给我国水稻生产造成极大的威胁,而对这种新的毁灭性病毒病却知之甚少。为此,亟需解决稻飞虱区域性迁飞规律、虫毒互作、毒源寻踪等科学问题,通过多学科交叉和宏微观结合及多尺度多途径的综合研究,探索稻飞虱发生与SRBSDV流行的互作机制(虫病地方性消长关系、两者在微观水平上的互作等),明确稻飞虱远距离传毒的行为与生理生化及分子机制(迁飞与病原摄带及传毒的关系),阐释各稻区飞虱与病毒的源库关联机制,揭示稻飞虱与SRBSDV区域性灾变的触发因子与调控机制,为保障国家粮食安全提供科学依据。更多还原

【Abstract】 Regional epidemics of the southern rice black-streaked dwarf virus(SRBSDV)and outbreaks of its rice planthopper (RPH) vectors,including the white backed planthopper,Sogatella furcifera (Horváth),and the small brown planthopper,Laodelphax striatellus (Fallén),have posed a significant threat to rice production and food security in China since 2009.At the present time,management of this epidemic disease is hampered by our poor understanding of both the disease and its vectors.It is therefore important to improve national and international cooperation so that multidisciplinary research can be used to investigate the outbreak mechanisms of both rice planthoppers and epidemic SRBSDV.Research should be focused on the regional migration patterns of vectors in East Asia and the interaction between virus and vectors,including migration pathways,immigration events,the distribution of the virus source area,the survival and circulation of the virus and vectors and the spatio-temporal evolution of SRBSDV.更多还原
