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.

PREPARING AND SUBMITTING FOR PUBLICATION A PICTORIAL, ANNOTATED KEY TO GONATOCERUS SPECIES AND OTHER GENERA AND SPECIES OF MYMARIDAE (HYMENOPTERA) EGG PARASITOIDS OF HOMALODISCA SPP. AND OTHER PROCONIINE SHARPSHOOTERS IN NORTH AMERICA, WITH EMPHASI


  • Author(s): Triapitsyn, Serguei; Morgan, David; Vickerman, Danel;
  • Abstract: This is the final report on this 1.5 yearlong taxonomic project (it was extended at no cost from 1 July 2005 till 31 December 2005). Two scientific papers, one (Triapitsyn et al. in review) with the description of a new species of Gonatocerus from Mexico and South America and the other (Triapitsyn in review) with an annotated, illustrated key to Gonatocerus species and two other genera and species of Mymaridae (Hymenoptera) egg parasitoids of Homalodisca spp. and other proconiine sharpshooters (Hemiptera: Cicadellidae: Proconiini) in North America, have been submitted for publication in Zootaxa (a WWW-based taxonomic journal). Following their publication (if accepted), the electronic reprints of both will be made available online with free access to anyone at http://www.mapress.com/zootaxa/, with interactive links from the CDFA Pierce's Disease Control Program and the UC ANR GWSS Workgroup websites. In this report, a tentative key (which excludes the descriptions of the new species from Mexico and South America and also two new species from California, both from the morrilli subgroup of the ater species group of Gonatocerus) is given to facilitate recognition of the genera and species of Mymaridae that are known parasitoids of proconiine sharpshooter eggs in the Nearctic region.
