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...

Characterization and Correlation of EPG Waveforms of Bactericera cockerelli (Hemiptera: Triozidae): Variability in Waveform Appearance in Relation to Applied Signal

The tomatoDpotato psyllid, Bactericera cockerelli (Sulc) (Hemiptera: Triozidae), was recently shown to be a vector of " Candidatus Liberibacter solanacearum" (Lso), a phloem-limited bacterium that ...

Comparative Behavioral and Protein Study of Salivary Secretions in Homalodisca spp. Sharpshooters (Hemiptera: Cicadellidae: Cicadellinae)

A novel brush-induced method to physically stimulate salivation was applied to the glassy-winged and smoke tree sharpshooters (Hemiptera: Cicadellidae: Cicadellinae). This technique enabled the dir...

Detection of the bacterium, Xylella fastidiosa, in saliva of glassy-winged sharpshooter, Homalodisca vitripennis

Homalodisca vitripennis ( Germar) ( Hemiptera: Cicadellidae), the glassy- winged sharpshooter, is one of the most important vectors of the bacterium, Xylella fastidiosa subsp. piercei ( Xanthomonad...

EPG combined with micro-CT and video recording reveals new insights on the feeding behavior of Philaenus spumarius

The meadow spittlebug Philaenus spumarius plays a key role in the transmission of the bacterium Xylella fastidiosa to olive in Apulia (South Italy). Currently, available data on P. spumarius feedin...

Formation of Stylet Sheaths in aere (in air) from Eight Species of Phytophagous Hemipterans from Six Families (Suborders: Auchenorrhyncha and Sternorrhyncha)

Stylet sheath formation is a common feature among phytophagous hemipterans. These sheaths are considered essential to promote a successful feeding event. Stylet sheath compositions are largely unkn...

Patterns of Xylella fastidiosa colonization on the precibarium of sharpshooter vectors relative to transmission to plants

Xylella fastidiosa is a bacterial plant pathogen that causes many plant diseases, including Pierce's disease of grapevines. Sharpshooter leafhopper (Hemiptera: Cicadellidae: Cicadellinae) vectors t...

Sharpshooters: a review of what moves Xylella fastidiosa

Sharpshooters (Hemiptera: Cicadellidae: Cicadellinae) and spittlebugs (Hemiptera: Aphrophoridae: Aphrophorinae) have a worldwide distribution and are often associated with many crops. Because the g...

Sharpshooter X Wave: Correlation of an Electrical Penetration Graph Waveform With Xylem Penetration Supports a Hypothesized Mechanism for Xylella fastidiosa Inoculation

Electrical penetration graph (EPG) monitoring is the most rigorous means of observation and quantification of feeding by piercing-sucking arthropods. Previous EPG studies with aphids and leafhopper...

Stylet penetration behaviors of Graphocephala atropunctata (Signoret) (Hemiptera, Cicadellidae): EPG waveform characterization and quantification

We analyzed the probing (stylet penetration) behaviors of the sharpshooter leafhopper Graphocephala atropunctata (Signoret) on grape with an alternating current (AC) electrical penetration graph (E...

Waveform characterization of the soybean stem feeder Edessa meditabunda: overcoming the challenge of wiring pentatomids for EPG

Stink bugs (Hemiptera: Heteroptera: Pentatomidae) are in general robust and restless insects, which makes them difficult to wire for electropenetrograph (EPG) studies. In addition, cuticular lipids...
