A biological control model to manage the vector and the infection of Xylella fastidiosa on olive trees
Xylella fastidiosa pauca ST53 is the bacterium responsible for the Olive Quick Decline Syndrome that has killed millions of olive trees in Southern Italy. A recent work demonstrates that a ration...
A cell-cell signaling sensor is required for virulence and insect transmission of Xylella fastidiosa
Cell-cell signaling in Xylella fastidiosa, a xylem-colonizing plant pathogenic bacterium, mediated by a fatty acid Diffusible Signaling Factor (DSF), is required to colonize insect vectors and to s...
A chitinase is required for Xylella fastidiosa colonization of its insect and plant hosts
Xylella fastidiosa colonizes the xylem network of host plant species as well as the foregut of its required insect vectors to ensure efficient propagation. Disease management strategies remain inef...
Age determination of the glassy-winged sharpshooter, Homalodisca vitripennis, using wing pigmentation
A red pigment is contained in the wing veins of the glassy-winged sharpshooter, Homalodisca vitripennis (Hemiptera: Cicadellidae). This insect is the main vector of the plant-pathogenic bacterium X...
Anatomy and histology of reproductive organs of female Homalodisca coagulata (Hemiptera : Cicadellidae : Proconiini), with special emphasis on categorization of vitellogenic oocytes
The anatomy and histology of female Homalodisca coagulata (Say) (Hemiptera: Ci-cadellida: Proconiini) reproductive organs is described using light microscopy. The reproductive organs of H. coagulat...
Anterior Foregut Microbiota of the Glassy-Winged Sharpshooter Explored Using Deep 16S rRNA Gene Sequencing from Individual Insects
The glassy-winged sharpshooter (GWSS) is an invasive insect species that transmits Xylella fastidiosa, the bacterium causing Pierce's disease of grapevine and other leaf scorch diseases. X. fastidi...
A paratransgenic strategy to block transmission of Xylella fastidiosa from the glassy-winged sharpshooter Homalodisca vitripennis
Arthropod-borne diseases remain a leading cause of human morbidity and mortality and exact an enormous toll on global agriculture. The practice of insecticide-based control is fraught with issues o...
A survey of potential insect vectors of the plant pathogenic bacterium Xylella fastidiosa in three regions of Spain
The emergence of a rapid-spreading olive disease associated with Xylella fastidiosa in southern Italy represents a high risk to susceptible crops in other countries of the Mediterranean basin, if i...
Background matching behaviour and pathogen acquisition: plant site preference does not predict the bacterial acquisition efficiency of vectors
Many insect-borne pathogens are heterogeneously distributed within their hosts: therefore, a vector's within-plant distribution may be a predictor of its exposure to pathogens. In this study, we se...
Bacterial diversity in potential cicadellids vectors of Xylella fastidiosa Wells et al. in coffee plants in Puerto Rico
Bacteria from head and body tissues of three potential insect vectors of Xylella fastidiosa (Xf), Apogonalia spp., Hortensia similis and Caribovia coffeacola, were isolated in periwinkle wilt (PW) ...
Biodiversity and ecology of potential vectors (Insecta: Hemiptera: Auchenorryncha) of Xylella fastidiosa Wells et al. in coffee plants of Puerto Rico
Xylella fastidiosa(Xf) is a xylem-limited bacterium that is the causal agent of coffee leaf scorch (CLS) in Central America. The purpose of this research was to survey potential vectors of Xf in pl...
Biology and biometry of sharpshooter Homalodisca coagulata (Homoptera : Cicadellidae) reared on cowpea
Stage-specific survival, growth, developmental biology, and biometry of the sharpshooter Homalodisca coagulata (Say) were studied in the laboratory under controlled conditions of 27 ± 1°...
