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...
Analysis of vector behavior as a tool to predict Xylella fastidiosa patterns of spread
The most likely scenarios for Xylella fastidiosa introduction in Central Europe is through infected ornamental plants, with a successive spillover from gardens and parks to cultivated orchards. G...
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...
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...
Fecundity and success of progeny produced by Homalodisca coagulata (Hemiptera : Cicadellidae) on single host species
This study tested the hypothesis that Homalodisca coagulata (Say) (Hemiptera: Cicadellidae) confined to a single host cannot successfully produce progeny and survive to complete a generation. We fo...
Feeding site preference of Dilobopterus costalimai Young and Oncometopia facialis (Signoret) (Hemiptera : Cicadellidae) on citrus plants
The efficiency of Xylella fastidiosa transmission by sharpshooters on citrus plants is low and varies with the vector species. The feeding behavior of the sharpshooter vector related to X. fastidio...
Plant Water Stress and Vector Feeding Preference Mediate Transmission Efficiency of a Plant Pathogen
Pathogen spread by arthropod vectors is the outcome of pathogen-vector-plant interactions, as well as how these interactions are impacted by abiotic and biotic factors. While plant water stress imp...
Relative Susceptibility of Vitis vinifera Cultivars to Vector-Borne Xylella fastidiosa through Time
Understanding the interactions between pathogen, crop and vector are necessary for the development of disease control practices of vector-borne pathogens. For instance, resistant plant genotypes ca...
ROOTSTOCK INFLUENCE ON OCCURRENCE OF HOMALODISCA-COAGULATA, PEACH XYLEM FLUID AMINO-ACIDS, AND CONCENTRATIONS OF XYLELLA-FASTIDIOSA
The influence of three Prunus rootstocks-a domestic plum, a domestic peach, and a peach from Brazil-on the occurrence of the vector of phony peach disease, Homalodisca coagulata, was assessed in a ...
Spittlebugs as vectors of Xylella fastidiosa in olive orchards in Italy
The recent introduction of Xylella fastidiosa in Europe and its involvement in the Olive Quick Decline Syndrome (OQDS) in Apulia (Salento, Lecce district, South Italy) led us to investigate the bio...
Suitability of Different Host Plants for Oviposition and Development of Homalodisca vitripennis (Hemiptera: Cicadellidae) and Its Implication on Mass Rearing
The glassy-winged sharpshooter, Hamalodisca vitripennis (Germar) (Hemiptera: Cicadellidae), is a major pest of grapevine (Vitis vinifera L.) in Texas and California. It is a known vector of Pierce'...
Transmission of Xylella fastidiosa by naturally infected Philaenus spumarius (Hemiptera, Aphrophoridae) to different host plants
The recent establishment of Xylella fastidiosa subspecies pauca in the southern Italian region of Apulia threatens agricultural crops and the environment. Olive is an important and widespread ancie...
