Glassy-winged sharpshooter back in the news

Glassy-winged sharpshooters made a tremendous spash in the California media back in the 90s when they were first introduced into California and began spreading Pierce's disease in grapes. They were never far from the minds of grape researchers and farmers, but the stories in the press almost completely disappeared. Until yesterday.

The Riverside Press Enterprise ran a 500-word story about renewed concerns of a Pierce's disease outbreak in Temecula wine country. According to the article, a grower and a UC Riverside scientist are warning that not enough wineries are applying a pesticide that kills the glassy-winged sharpshooter.

UC Riverside entomologist Nick Toscano told the paper that as many as 40 percent of Temecula-area wineries do not apply the pesticide to control GWSS, which sets the winery back $175 to $210 an acre.

There have been no widespread outbreaks of Pierce's disease since the late 1990s, but sharpshooters are still found in local vineyards, according to the article. The week of April 28, it said, close to 40 sharpshooters were caught in UC Riverside's sticky traps.

An interesting side note: The Press Enterprise posted a four-minute podcast with the story, which is simply an automated text reader robotically saying the words in the story.
