Abstract:

Maize chlorotic mottle virus is one of the important quarantine plant viruses in China. The co\|infection of Maize chlorotic mottle virus (MCMV) and potyviridae group viruses will cause corn lethal necrosis (CLN), and cause severe economic losses. Potyviruses had wide suitable distribution areas, so to understand the research ststus on MCMV and its transmission vector is of important significance. This paper summarized the present research status on MCMV and its vectors in recent years, combining with our own studies; reviewed the role of western flower thrips as MCMV vector in CLN, so as to provide theoretical referrences for the fundamental research on and control of MCMV transmission mediated by F.occidentalis.

摘要：

玉米褪绿斑驳病毒(Maize chlorotic mottle virus，MCMV)是中国重要检疫性病毒之一，该病毒与马铃薯Y病毒属成员复合侵染会造成玉米致死性坏死（CLN），造成严重的经济损失。由于玉米上马铃薯Y病毒属病毒有广泛适生范围，一旦扩散开来，将对玉米生产构成严重威胁。因此，了解MCMV研究的现状和传播介体具有重要意义。综述了近几年MCMV研究进展和传播介体概况，并结合自身研究，评述了西花蓟马作为MCMV传播介体在CLN中的作用，以期为西花蓟马传播MCMV的基础研究和防控提供理论依据。
