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.

Biological aspects of the leafhoppers Acrogonia gracilis (Osborn), Dilobopterus costalimai Young and Oncometopia facialis (Signoret) (Hemiptera: Cicadellidae) on Citrus sinensis L. Osbeck

  • Author(s): Benvenga, Sergio; Gravena, Santin; Paiva, Paulo;
  • Abstract: The biological aspects of the leafhoppers Acrogonia gracilis (Osborn), Dilobopterus costalimai Young and Oncometopia facialis (Signoret) on young plants of Citrus sinensis L. Osbeck was studied at 25+-2degreeC, relative humidity of 60+-10% and photophase of 12h. These species are vectors of Xylella fastidiosa Wells to citrus. Five instars were observed for D. costalimai and O. facialis and six for A. gracilis. The mean duration from egg to adult and longevity were, respectively, 54.5 and 72.4 days for A. gracilis, 54.7 and 36.4 days for D. costalimai and 67.1 and 15.5 days for O. facialis.
