What is Pierce's Disease?

Pierce's Disease is a bacterial infection, which is spread by bugs that feed on grapevines, particularly the "glassy winged sharpshooter." Grapevines that become infected with PD can quickly become sick and die.

Further new genus-group names in the Cicadellidae (Hemiptera)


  • Author(s): McKamey, Stuart;
  • Abstract: New replacement names are proposed for 11 genera or subgenera of leafhoppers in the subfamilies Coelidiinae, Ledrinae, Macropsinae, Scarinae, Typhlocybinae, and Ulopinae: Davduospina for Duospina Davies, Dialodia for Lodia Nielson, Doowella for Woodella Evans, Hobemanella for Bohemanella DeLong & Freytag (subgenus of Polana), Latycephala for Platycephala, Lesinda for Selinda Theron, Lonnia for Nollia Hamilton, Negoneura for Genoneura Dlabola, Olidiana for Lodiana Nielson, Ruana for Urana Coelho & Nessimian (subgenus of Gypona), and Varpulana for Parvulana DeLong & Freytag (subgenus of Polana). The new generic names circumscribe 116 valid species, 93 of which are here proposed in new combinations. Twenty-two of the remainder are in preoccupied scarine subgenera. Lodiana pectinata Yang & Zhang (1995) is preoccupied by L. pectinata Nielson (1982)-the new replacement name Olidiana yangi McKamey is proposed to replace the junior primary homonym. One of the new combinations involves a known vector of phytopathogens, the sandal leafbopper (now Ofidiana indica [Walker]). The spellings of Humpatagallia Linnavuori & Viraktamath (Agalliinae) and Limassolla Dlabola (Typhlocybinae) are fixed as correct.
