Abstract Homalodisca vitripennis (Germar) (Hemiptera: Cicadellidae), the glassy-winged sharpshooter, is one of the most important vectors of the bacterium, Xylella fastidiosa subsp. piercei (Xanthomonadales: Xanthomonadaceae) that causes Pierce's Disease in grapevines in California. In the present study we report a new method for studying pathogen transmission or probing behavior of H. vitripennis. When confined, H. vitripennis attempt to probe the surface of sterile containers 48 hours post… 
Sharpshooters: a review of what moves Xylella fastidiosa
TLDR
How fundamental principles of vector reproductive biology, behaviour, nutrition and population and community ecology have influenced research on insect vectors is demonstrated and provides insights into priority research areas.
Feeding behavior in relation to spittlebug transmission of Xylella fastidiosa
TLDR
The first insights into the transmission dynamics of the bacterium Xylella fastidiosa by the meadow spittlebug Philaenus spumarius are provided through DC EPG-assisted transmission tests and comparative observations of the probing and feeding behavior of infective versus non-infective vectors on healthy olive plants.
Genetic and endosymbiotic diversity of Greek populations of Philaenus spumarius, Philaenus signatus and Neophilaenus campestris, vectors of Xylella fastidiosa
TLDR
The genetic variation of Greek populations of three spittlebug species is investigated, by examining the molecular markers Cytochrome Oxidase I, cytochrome b and Internal Transcribed Spacer, to understand the population dynamics of vectors of X. fastidiosa with a view to formulate effective management strategies towards the bacterium.
Anatomy of male and female reproductive organs of stink bugs pests (Pentatomidae: Heteroptera) from soybean and rice crops
TLDR
The anatomy of the female and male reproductive tracts of three important agricultural pests in Colombia is described and reproductive biology of insects provides informative characters for behavioral and evolutionary studies, as well as useful data for pest control strategies.
Molecular intervention in Pierce's Disease
TLDR
The main goal of this research was to generate recombinant antibodies to be used to investigate the interaction of MopB with the plant and GWSS, and the successful application of the 4XfMopB3 antibody in ELISA, Western blot and immunofluorescence assays.
Proceeding From in vivo Functions of Pheromone Receptors: Peripheral-Coding Perception of Pheromones From Three Closely Related Species, Helicoverpa armigera, H. assulta, and Heliothis virescens
TLDR
Three closely related species, Helicoverpa armigera, H. assulta, and Heliothis virescens from Lepidoptera Noctuidae, are used as a model system for exploring sexual communication and species isolation and PRs named OR6, OR13, and OR16 among these species were found to be functional, characterized by an in vitro Xenopus oocytes system.
Rapid evolution of chemosensory receptor genes in a pair of sibling species of orchid bees (Apidae: Euglossini)
TLDR
The results suggest that rapid changes in the chemosensory gene family occurred among closely related species of orchid bees, consistent with the hypothesis that strong divergent selection acting on chemOSensory receptor genes plays an important role in the evolution and diversification of insect pheromone systems.
A delivery system for field application of paratransgenic control
TLDR
A novel microencapsulation platform for containment and targeted delivery of engineered bacteria to the gut of a disease-transmitting arthropod and targeted release of bacteria into the physiologically relevant region of the insect gut is introduced.

Transmission of Xylella fastidiosa to Grapevines by Homalodisca coagulata (Hemiptera: Cicadellidae)
TLDR
In laboratory experiments, the major characteristics of H. coagulata’s transmission of X. fastidiosa to grapevines were the same as reported for other vectors: short or absent latent period; nymphs transmitted but lost infectivity after molting and regainedinfectivity after feeding on infected plants; and infectivity persisted in adults.
Acquisition and retention of Xylella fastidiosa by an efficient vector, Graphocephala atropunctata.
TLDR
The blue-green sharpshooter (BGSS), Graphocephala atropunctata (Signoret), is an efficient vector of Xylella fastidiosa Wells et al, the causal bacterium of Pierce's disease of grapevine, which increased transmission efficiency between 1 h and 7 days post-acquisition and remained high thereafter.
Vector Transmission of Xylella fastidiosa to Dormant Grape.
TLDR
These findings provide evidence that X. fastidiosa transmission does not require negative pressure in plant xylem to be inoculated into plants, and are a potential problem in California vineyards adjacent to citrus groves or other habitats with large overwintering populations of H. coagulata.

Vector Transmission of Xylella fastidiosa: Applying Fundamental Knowledge to Generate Disease Management Strategies
TLDR
Basic aspects of X. fastidiosa transmission by vectors, the ecology of insects in relation to transmission and disease spread, and how basic research can be applied to the development of management strategies for a X.FastidiosA disease are discussed.
Stylet Penetration by Adult Homalodisca coagulata on Grape: Electrical Penetration Graph Waveform Characterization, Tissue Correlation, and Possible Implications for Transmission of Xylella fastidiosa
Abstract The sharpshooter Homalodisca coagulata (Say) (Hemiptera: Cicadellidae: Cicadellinae) is an exotic vector of the Pierce’s disease (PD) bacterium, Xylella fastidiosa (Wells et al.), that was
Fastidious xylem-limited bacterial plant pathogens.
Numerous bacteria have been isolated from within plants, and many reported from xylem, but only three species of xylem-limited bacteria (XLB) that are fastidious in cultural requirements, are plant
Cell-cell signaling controls Xylella fastidiosa interactions with both insects and plants.
TLDR
It is shown that a diffusible signal molecule is required for biofilm formation in the vector and for vector transmission to plants, and identified the genes regulated by rpfF, which are more virulent than the wild type when mechanically inoculated into plants.
