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.

UC researchers developed an eye gnat trap anyone can make at home.

Lean-N-Green Day, Farm & Nutrition Day mark National Nutrition Month

UC Cooperative Extension took part in the annual Lean-N-Green Day at Grand Oaks Elementary School in Shasta Lake this week, reported Joe Szydiowski in the Redding Record-Searchlight.

UCCE nutrition educator Lori Coker helped children play the "Sugar Cube Game," in which students raced to amass white sugar blocks to reach the amount in a bottle of soda. An 11-year-old participant told the reporter she would be telling her family about the surprising amount of sugar in their favorite drinks.

Farm & Nutrition Day Planned for March 23 at Fresno Fairgrounds
California Ag Network

Fresno County third-graders will convene at the Fresno Fairgrounds March 23 for an agricultural and food-related field trip organized by the Fresno County Farm Bureau. A focus of the event is learning the importance of making healthy food choices, much of which is provided by Fresno County's bounty of diversified crops and products.

UC Cooperative Extension nutrition educators will present a play that helps the children recognize "MyPlate" as a guide to healthy eating and uses a "Strong-O-Meter" to encourage active play. In addition, the UC Kearney Agricultural Research and Extension Center staff and UC Cooperative Extension farm advisors will staff booths teaching children about farming and gardening.
