Comparative dispersal of Homalodisca coagulata and Homalodisca liturata (Homoptera : Cicadellidae)
California's viticulture and ornamental industries have suffered significant losses since the introduction of Homalodisca coagulata (Say), an important vector of the Pierce's disease bacterium. A b...
Effects of citrus and avocado irrigation and nitrogen-form soil amendment on host selection by adult Homalodisca vitripennis (Hemiptera : Cicadellidae)
Host plant water status is thought to influence dispersal of the xylophagous leafhopper Homalodisca vitripennis Germar, especially where plants are grown under high evaporative demand. Preference b...
Emerging plant diseases under a changing climate scenario: Threats to our global food supply
Estimation of Feeding Threshold for Homalodisca vitripennis (Hemiptera: Cicadellidae) and Its Application to Prediction of Overwintering Mortality
The glassy-winged sharpshooter, Homalodisca vitripennis (Germar), vectors the bacterium Xylella fastidtosa that induces Pierce's disease of grape This study determined the effect of temperature on ...
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...
Functional Characterization of Replication and Stability Factors of an Incompatibility Group P-1 Plasmid from Xylella fastidiosa
Xylella fastidiosa strain riv11 harbors a 25-kbp plasmid (pXF-RIV11) belonging to the IncP-1 incompatibility group. Replication and stability factors of pXF-RIV11 were identified and used to constr...
Influences of Temperature on Homalodisca vitripennis (Hemiptera: Cicadellidae) Survival Under Various Feeding Conditions
Survival of the glassy-winged sharpshooter, Homalodisca vitripennis (Germar) (Hemiptera: Cicadellidae), was studied under various constant temperatures and feeding conditions. When provided a host ...
Large-Scale Intersubspecific Recombination in the Plant-Pathogenic Bacterium Xylella fastidiosa Is Associated with the Host Shift to Mulberry
Homologous recombination plays an important role in the structuring of genetic variation of many bacteria; however, its importance in adaptive evolution is not well established. We investigated the...
Observations of acoustic signaling in three sharpshooters: Homalodisca vitripennis, Homalodisca liturata, and Graphocephala atropunctata (Hemiptera : cicadellidae)
Observations and comparative data are presented on the acoustic signals of three sharpshooter (Hemiptera: Auchenorrhyncha: Cicadellidae: Cicadellinae) species native to North America. The acoustic ...
Recent Evolutionary Radiation and Host Plant Specialization in the Xylella fastidiosa Subspecies Native to the United States
The bacterial pathogen, Xylella fastidiosa, infects many plant species in the Americas, making it a good model for investigating the genetics of host adaptation. We used multilocus sequence typing ...
Seasonal patterns of female Homalodisca coagulata (Say) (Hemiptera : Cicadellidae) reproductive physiology in Riverside, California
Female Homalodisca coagulata (Say) were collected from October 2001 to February 2005 from citrus at the University of California, Riverside. Between 5 and 20 females per sampling date were dissecte...
Spatial and temporal dynamics of overwintering Homalodisca coagulata (Hemiptera : Cicadellidae)
A 4-yr landscape-scale study was conducted to investigate spatial and temporal dynamics of overwintering Homalodisca coagulata (Say) (Hemiptera: Cicadellidae) in the lower San Joaquin Valley, Calif...
