Nutritional deficiency in citrus with symptoms of citrus variegated chlorosis disease

Brazilian Journal of Biology
It is well known that citrus plants that have been infected by Xylella fastidiosa display nutritional deficiencies, probably caused by production of extracellular polymers by the bacteria that block normal nutrient flow through the xylem. The aim of this

Specific amplification of iron receptor genes in Xylella fastidiosa strains from different hosts

Genetics and Molecular Biology, 2006
Bacterial production of siderophores may involve specific genes related to nonribosomal peptide and polyketide biosynthesis, which have not been fully identified in the genome of Xylella fastidiosa strain 9a5c.

Comparison of protocols for the extraction of genomic DNA from Sharpshooters (Hemiptera: Cicadellidae) for the detection of Xylella fastidiosa

Arquivos do Instituto Biológico, 2018
: The bacterium Xylella fastidiosa, the causal agent of citrus variegated chlorosis (CVC), is dependent on vector insects for its spread and infection of citrus hosts.

A high‐throughput analysis of high‐resolution X‐ray CT images of stems of olive and citrus plants resistant and susceptible to Xylella fastidiosa

Plant Pathology, Volume 73, Issue 3, Page 630-643, April 2024.
Though morphological traits of resistant olives (narrow vessels) and citrus' (connected vessels) are distinct, across both taxa, susceptible cultivars have many more vessels; representing a potentially broader‐reaching trend. Abstract The bacterial plant pathogen Xylella fastidiosa causes disease in several globally important crops.

Beyond the present: How climate change is relevant to pest risk analysis

EPPO Bulletin, Volume 54, Issue S1, Page 20-37, March 2024.
Abstract Climate change is widely recognized as a critical global challenge with far‐reaching consequences. It affects pest species by altering their population dynamics, actual and potential distribution areas, as well as interactions with their hosts and natural enemies. Climate change thus has potentially important implications for multiple areas of

Prevalence of the endoparasitoid Verrallia aucta in Central Scotland: A potential biocontrol for Philaenus spumarius (Hemiptera, Aphrophoridae), an important vector of Xylella fastidiosa

Journal of Applied Entomology, Volume 148, Issue 2, Page 158-170, March 2024.
Abstract Xylella fastidiosa is a bacterial plant pathogen transmitted by xylem‐feeding insect vectors such as the meadow spittlebug, Philaenus spumarius (Hemiptera, suborder Auchenorrhyncha, family Aphrophoridae). Although X. fastidiosa is not currently found in the UK, methods for reducing vector populations will play an important role in controlling ...

Pest risk assessment of Leucinodes orbonalis for the European Union

EFSA Journal, Volume 22, Issue 3, March 2024.
Abstract Following a request from the European Commission, the EFSA Panel on Plant Health performed a quantitative risk assessment of Leucinodes orbonalis (Lepidoptera: Crambidae), the eggplant fruit and shoot borer, for the EU. The assessment focused on potential pathways for entry, climatic conditions favouring establishment, spread and impact ...
