A New Resource for Research and Risk Analysis: The Updated European Food Safety Authority Database of Xylella spp. Host Plant Species
Following a series of requests for scientific advice from the European Commission starting in 2013, the European Food Safety Authority (EFSA) conducted a pest risk assessment and created a comprehe...
Antagonistic activity of olive endophytic bacteria and of Bacillus spp. strains against Xylella fastidiosa
Strains of Xylella fastidiosa subsp. pauca characterized by a specific genotype, the so called sequence type "ST53", have been associated with a severe disease named Olive Quick Decline Syndrome ...
Biotechnological and Agronomic Potential of Endophytic Pink-Pigmented Methylotrophic Methylobacterium spp.
The genus Methylobacterium is composed of pink-pigmented facultative methylotrophic (PPFM) bacteria, which are able to synthesize carotenoids and grow on reduced organic compounds containing one ca...
Combination of Chromogenic Differential Medium and estA-Specific PCR for Isolation and Detection of Phytopathogenic Xanthomonas spp.
A xanthomonad differential medium (designated Xan-D medium) was developed, on which streaks and colonies of xanthomonads, including 13 species of the genus Xanthomonas, turned wet-shining yellow-gr...
Comparative Behavioral and Protein Study of Salivary Secretions in Homalodisca spp. Sharpshooters (Hemiptera: Cicadellidae: Cicadellinae)
A novel brush-induced method to physically stimulate salivation was applied to the glassy-winged and smoke tree sharpshooters (Hemiptera: Cicadellidae: Cicadellinae). This technique enabled the dir...
Detection of siderophores in endophytic bacteria Methylobacterium spp. associated with Xylella fastidiosa subsp pauca
The objective of this work was to study the production of siderophores by endophytic bacteria Methylobacterium spp., which occupy the same ecological niche as Xylella fastidiosa subsp. pauca (Xfp) ...
Diversity and abundance of leafhoppers in Canadian vineyards
Leafhoppers (Hemiptera: Cicadellidae) are pests of many temperate crops, including grapevines (Vitis species). Uncontrolled populations can induce direct and indirect damage to crops due to feeding...
Pest categorisation of non-EU Cicadomorpha vectors of Xylella spp.
The Panel on Plant Health performed a group pest categorisation of non-EU Cicadomorpha vectors of Xylella spp. known to be associated with plant diseases. Although all the insects considered in thi...
Response to scientific and technical information provided by an NGO on Xylella fastidiosa
Following the publication of the Scientific Opinion by EFSA's PLH Panel which assessed the risk to plant health posed by Xylella fastidiosa in the EU territory and evaluated risk reduction options,...
Susceptibility of Citrus spp., Quercus ilex and Vitis spp. to Xylella fastidiosa strain CoDiRO
Following a request from the European Commission, the EFSA Plant Health Panel analysed a dossier submitted by the Italian Authorities to reach a conclusion on the status of Vitis spp., Citrus spp. ...
Temporal Patterns in Homalodisca spp. (Hemiptera: Cicadellidae) Oviposition on Southern California Citrus and Jojoba
A detailed study of the distribution of egg masses of Homalodisca vitripennis (Germar) and H. liturata Ball was done across a 2-yr period (2001-2003) on six host plants in southern California (Mars...
Universal detection of phytoplasmas and Xylella spp. by TaqMan singleplex and multiplex real-time PCR with dual priming oligonucleotides
Phytoplasmas and Xylella spp. are bacteria that cause many economically important plant diseases worldwide. TaqMan probe-based quantitative real-time polymerase chain reaction (qPCR) assays have be...
