Eye gnats still annoying San Diego County residents

Researchers, farmers, community members and county officials gathered in Escondido yesterday to discuss clouds of eye gnats that have been plaguing residents of south Escondido and Jacumba for the last few years, reported Gary Warth in the North (San Diego County) Times.

UC Cooperative Extension advisor James Bethke, a nursery and floriculture expert, moderated the San Diego County Eye Gnat Research and Education Symposium.

"We don't need to have crop-dusters flying over Escondido to deal with this situation," Bethke said. 

However, he conceded, there still is much researchers do not know about the eye gnat.

"I was very amazed to learn that almost nobody is researching this," Bethke said.

UCCE research associate Bryan Vander also spoke at the symposium. He said people have been trying to fight gnats since at least 1932, when a researcher in the Coachella Valley made an 8-foot-tall trap for $76 that reportedly caught 109,777 gnats a day.

Vander said UCCE researchers have designed a smaller, less-expensive trap that has proven effective against eye gnats. A plastic bottle is filled with a mixture of raw eggs and water that has been left till it emits a "pungent smell." Complete instructions are posted online.

Cooling cattle; European pepper moth examined

For an article "Should Wyoming livestock and ag adjust to climate?" in the Billings Gazette, reporter Paul Murray sought information about livestock animals' response to warmer temperatures from Frank Mitloehner, UC Cooperative Extension Specialist in the Department of Animal Science at UC Davis. Mitloehner talked about ways animals can cool down and discussed shade, fans, sprinklers and even alternative cattle breeds. "We're seeing more and more extreme weather. That is a tendency we're seeing more and more often. That can stress animals. Similar to animals in the wild, that can impact animals' reproductive ability and their performance," he told the reporter.

European pepper moth widespread in California
Surendra Dara for Western Farm Press

Western Farm Press published this article about European pepper moth by Surendra Dara, UC Cooperative Extension farm advisor in Santa Barbara County. Dara explains that the European pepper moth has been reported in several central and southern California counties. The pest prefers to feed at the plant base of crops such as corn, peppers, tomatoes, squash, strawberries and some ornamental plants. Dara has been appointed to the national Technical Working Group for European pepper moth, along with UC Cooperative Extension colleagues James Bethke and Steve Tjosvold.

Dara also wrote about this pest and shared photos of it on the UC Strawberries and Vegetables blog.
