Tracking the source regions of Southern rice black-streaked dwarf virus (SRBSDV)occurred in Wuyi county, Zhejiang province, China in 2009, transmitted by Sogatella furcifera(Horváth)(Homoptera: Delphacidae)
摘要
Abstract
In 2009, Southern rice black-streaked dwarf virus (SRBSDV) appeared first time in Zhejiang province, while only in Wuyi county morbidity phenomenon occurred. Since this virus is a kind of arbovirus, and the white-backed planthopper, Sogatella fwrcifera (Horvdth) (WBPH), is its main transmitted vector, we used light trap catch data, migration trajectory simulation, synoptic meteorological background and virus infection to study the pathways of WBPH in Wuyi, Zhejiang, 2009. In this way, the possible source regions of SRBSDV transmitted by its vector WBPH were analyzed, and the biological parameters for trajectory analysis were determined based on the numerical simulation. This research aims to establish scientific basis for the macro-epidemic researching of SRBSDV. The results illustrated that:(1) through the overlapping analysis of the virus incidence area and the main WBPH source regions of Wuyi imitated through backward trajectory simulations, the possible virus source areas of Wuyi were mainly distributed in Guangdong, Guangxi, southern Fujian and southern Jiangxi provinces or regions.(2) Riding on the prevailing southwest wind or south wind, WBPH transmitted this virus from southern China to Wuyi. (3) It was the immigration of concentrated airborne WBPH with downdraft and rainfall that triggered the epidemic outbreak of SRBSDV in Wuyi in 2009.关键词
