Mechanical transmission of Potato leafroll virus
Like typical luteoviruses, Potato leafroll virus (PLRV) cannot be transmitted mechanically by rubbing plants with solutions containing virus particles. However, PLRV was found to be mechanically transmissible from extracts of plants that had been inoculated by viruliferous aphids and then post-inoculated with Pea enation mosaic virus-2 (PEMV-2). Unlike

Relative Prevalence of Grapevine Leafroll-Associated Virus Species in Wine Grape-Growing Regions of California. [PDF]
Some diseases manifest as one characteristic set of symptoms to the host, but can be caused by multiple pathogens. Control treatments based on plant symptoms can make it difficult to effectively manage such diseases, as the biology of the underlying ...

Identification of grapevine virus G and grapevine virus H in Sardinia, Italy
Grapevine virus G (GVG) and grapevine virus H (GVH) (genus Vitivirus) are recently discovered viruses. Analysis of 38 samples from Sardinian grapevine cultivars for the presence of GVG and GVH was carried out using RT-PCR.

Hemipteran vectors of stylet‐borne plant viruses: Aphids lead the charge
Among all sap‐feeding hemipterans, aphids stand out by far as the most important vectors of noncirculative plant viruses. Compared to whiteflies and mealybugs, aphids’ highly specialized stylet anatomy and distinct feeding behaviors contribute, together with other features of their biology, to their remarkable efficiency in transmitting stylet‐borne ...

Potato leafroll virus, its purification from its vector Myzus persicae [PDF]
Experiments were described on the purification of potato leafroll virus (PLRV) from its vector Myzus persicae. Preliminary experiments demonstrated that much non- viral material had to be removed from aphid macerates to obtain a pure virus preparation ...

Control of leafrollers in avocados
Brownheaded leafrollers Ctenopseustis obliquana and C. herana can cause significant damage to young avocado fruitlets and terminal shoots. Field trials were performed in 1996/97 and 1997/98 on avocado trees to evaluate leafroller control with tebufenozide, taufluvalinate, Bacillus thuringiensis var. kurstaki (Btk) and abamectin.

A global assessment of the viruses transmitted by the peach‐potato aphid (Myzus persicae)
The viruses transmitted by Myzus persicae, including proportions by family, order and transmission type (persistent, semi‐persistent and non‐persistent), are provided. Latin binomials and common names are documented for each virus Virus presence in GB matches well with the rest of NW Europe, but with 25 exceptions.

The site of potato leafroll virus multiplication in its vector, Myzus persicae : an anatomical study [PDF]
In search of the site of PLRV multiplication in its vector a detailed study was made of the anatomy of the aphid, Myzus persicae SULZ. The findings are summarized in the following lines:Alimentary canalThe most anterior part of the alimentary canal is ...
