Application of competitive enzyme-linked immunosorbent assay for the quantification of imidacloprid titers in xylem fluid extracted from grapevines
A competitive enzyme-linked immunosorbent assay (ELISA) technique was evaluated for quantifying titers of imidacloprid in xylem fluid extracted from Vitis vinifera L. grapevines that were treated w...
Colony aggregation and biofilm formation in xylem chemistry-based media for Xylella fastidiosa
Two chemically defined media based on xylem fluid chemistry were developed for Xylella fastidiosa. These media were tested and compared to chemically defined media XDM2, XDM4 and XF-26. New media w...
Differential expression of genes of Xylella fastidiosa in xylem fluid of citrus and grapevine
Xylella fastidiosa causes a serious Pierce's disease (PD) in grapevine. Xylella fastidiosa cells from a PD strain were grown in a pure xylem fluid of a susceptible grapevine cultivar vs. xylem flui...
Feeding and Development of the Glassy-Winged Sharpshooter, Homalodisca vitripennis, on Australian Native Plant Species and Implications for Australian Biosecurity
In any insect invasion the presence or absence of suitable food and oviposition hosts in the invaded range is a key factor determining establishment success. The glassy-winged sharpshooter, Homalod...
Feeding and survival of citrus sharpshooters (Hemiptera : Cicadellidae) on host plants
The liquid excretion and survival of the sharpshooters Dilobopterus costalimai Young and Oncometopia facialis (Signoret), vectors of Xylella fastidiosa in citrus, were measured on various host plan...
Influence of Vitis xylem fluid and xylem fluid plus cecropin on growth of Xylella fastidiosa
Colony growth of Xylella fastidiosa (UCLA ID and STL PD strains) was quantified after incubation for 48 h in xylem fluid of Vitis rotundifolia Michx. cv. Noble and Vitis vinifera L. cv. Chardonnay....
Influence of xylem fluid chemistry on planktonic growth, biofilm formation and aggregation of Xylella fastidiosa
Xylella fastidiosa is the causal agent of Pierce's disease in grapevines. The mechanisms of pathogenicity are largely due to occlusion of xylem vessels by aggregation of X. fastidiosa and biofilm f...
Metabolic complementarity and genomics of the dual bacterial symbiosis of sharpshooters
Mutualistic intracellular symbiosis between bacteria and insects is a widespread phenomenon that has contributed to the global success of insects. The symbionts, by provisioning nutrients lacking f...
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 ...
