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,...

Diseases caused by Tobacco streak virus (TSV) have resulted in significant crop losses in sunflower and mung bean crops in Australia. Two genetically distinct strains from central Queensland, TSV-parthenium and TSV-crownbeard, have been previously described. They share only 81% total-genome...

Groundnut ringspot virus (GRSV), genus Tospovirus, is a thrips-transmitted virus infecting peanuts (Arachis hypogaea L.) in Córdoba province, Argentina. Fourteen viral isolates were recovered from Tospovirus-like symptomatic plants from different peanut fields. Viral isolates as GRSV were...

Pelargonium (Pelargonium spp.) plants showing leaf mild mottle symptoms were collected in August 2014 from a park at Chaoyang district, Beijing, China. Based on the results of ELISA, PCR assay, nucleotide sequence comparisons, and pathogenicity tests, the causal agent was identified as Pelargonium...

PVY is distributed worldwide in potato growing areas, tobacco growing areas and outdoor crops of tomato and pepper in warm countries. The different strains of PVY develops different symptoms on different parts of the host plant species. The PVY have a host range of 495 species in 72 genera of 31...

Arthropods considered viral vectors are early pests in the tomato crop and have the ability to cause direct or indirect damage, especially when there are failures in their management. The aim of this work was to study the incidence and infestation of viral vectors in two systems of pest management...

Species of the genus Scirtothrips Shull are minute insects of which several are major pests on the leaves of various crops around the world. In this study, S. dorsalis is recorded for the first time from Iran. Body mainly yellow but antecostal ridge on tergites and sternites is dark brown and...

Diseases of unknown aetiology remain difficult or impossible to diagnose. Illumina next generation sequencing (NGS) technology was used to generate sequence datasets from citrus affected by two such diseases: citrus chlorotic dwarf (CCDD) (whitefly-transmitted) and yellow vein clearing disease...

Taxonomy: Iris yellow spot virus (IYSV) is in the genus Tospovirus, family Bunyaviridae, with a single-stranded, tri-segmented RNA genome with an ambisense genome organization. Members of the other genera in the family infect predominantly vertebrates and insects. Geographical distribution: IYSV is ...
