Egg-laying and brochosome production observed in glassy-winged sharpshooter

  • Author(s): Hix, Raymond L.
  • et al.

Glassy-winged sharpshooter (GWSS) females form white spots on the forewings from secretions of ultramicroscopic bodies known as brochosomes. This occurs after mating of the GWSS and just prior to egg laying. The first published reports of wing spots were made by Riley and Howard in 1893. The behaviors associated with brochosome formation could have important implications for integrated pest management (IPM) programs to control GWSS, an important vector of the bacterium that causes Pierce's disease in grapevines and other crops.
