In order to clarify the cryptic species of the whitefly Bemisia tabaci transmitting Cotton leaf curl Multan virus (CLCuMuV) in Guangdong Province, molecular identification, whitefly transmission and molecular detection were conducted in the study. The results indicated that, in the fields occurring ...

In this study, we monitored the carrying rate of ToCV of Bemisia tabaci in major tomato production areas of China in 2013 and 2014. We discovered that in 2013, among all B. tabaci samples collected from 16 different areas of China, those from Yuncheng Shanxi, Taiyuan Shanxi, Shanghe Shandong,...

The investigation showed that there were 6 kinds of virus diseases of tobacco in Guangxi, which were tobacco mosaic virus (TMV) disease, tobacco cucumber mosaic virus (CMV) disease, tobacco potato y virus (PVY) disease, tobacco etch virus (TEV) disease, tobacco ringspot virus (TRSV) disease and...

The whitefly Bemisia tabaci is a major pest of tropical, subtropical and the adjacent temperate zones. In the past 20 years, the B biotype of this species complex has been spreading to many regions of the world with the assistance of human movement of ornamental plants, and in many regions of...

The pinewood nematode Bursaphelenchus xylophilus is a destructive invasive species in the world. The pine wilt disease caused by it is destructive for pine (Pinus spp.) trees. The pine wilt disease is diffused through vector insects in the field. There are 45 insect species that can transmit the...

Seven species of Monochamus (M. urussovii, M. sutor, M. saltuarius, M. subfasciatus, M. galloprovincialis pistar, M. guttulatus and M. alternatus) from Jilin province, China, are reported, among which M. alternatus is a new record for Jilin province. The distribution, morphological characters, host ...

A virus was isolated from naturally infected Cucurbita moschata plants in Beijing, China. It was identified to Zucchini yellow mosaic virus based on biological, serological and molecular tests. To characterize the 3′ terminal sequences of the genome, the 3′ terminal sequences were amplified by...

Four hybridoma cell lines secreting monoclonal antibodies (MAbs) against rice stripe virus (RSV) were produced by fusing mouse myeloma cells (SP2/0) with spleen cells from BALB/c immunized by the RSV particles. The titres of ascitic fluids of four MAbs ranged from 1:80 000 to 1:5 120 000 tested by...
