Polymerase chain reaction (PCR) is routinely used for the detection of grapevine red blotch virus (GRBV), a virus with a circular single-stranded DNA genome, in grapevine tissue. Since the preparat...

A direct tissue blot immunoassay (DTBIA) technique has been compared with ELISA and PCR for detection of Xylella fastidiosa in olive trees from Apulia (southern Italy). Fresh cross-sections of youn...

Approaches to control vector-borne diseases rarely focus on the interface between vector and microbial pathogen, but strategies aimed at disrupting the interactions required for transmission may le...

In Northern California, surveys of several vineyards planted to Vitis vinifera cv. Pinot noir (PN) clones 02A, 667, 777, and UCD 04 grafted onto the rootstock V berlandieri x V rupestris 110 Richte...

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...

Next generation sequence analyses were used to assess virus-derived small RNA (vsRNA) profiles for Homalodisca coagulata virus-1 (HoCV-1), family Dicistroviridae, and Homalodisca vitripennis reovir...

Generalist pathogens frequently exist as a complex of genetically differentiated strains, which can differ in virulence and transmissibility. A description of the extent to which strain variability...

Hemipteran insects are devastating pests of crops due to their wide host range, rapid reproduction, and ability to transmit numerous plant-infecting pathogens as vectors. While the field of plant-v...
