The influx of invasive species has been on the rise in the last decade. One invasive insect recently detected in the North Coast counties of Mendocino and Lake is the Virginia creeper leafhopper (VCLH), Erythroneura ziczac. UC IPM Advisor Lucia Varela, in collaboration with Mendocino County Viticulture and Plant Science Advisor Glenn McGourty, is investigating VCLH. VCLH is similar in appearance
and life cycle to the native western grape leafhopper (WGLH), Erythroneura elegantula. View the videos to distinguish the two species. The difference is that WGLH is well controlled by a complex of Anagrus species egg parasites while VCLH, as a new invasive, is not. While insecticides that effectively control WGLH also control VCLH in conventional vineyards, in organic vineyards VCLH control is more difficult due to high populations, and damage has been observed. Native to the northern Midwest, VCLH was first spotted in Northern California in the late 1980s. Since then it has been moving southward and was detected in the northern Sacramento Valley and northern Sierra Foothills by 2008.

New pest found in California vineyards
Reporter Vicky Boyd based the article on a report by Lucia Varela, UC Cooperative Extension advisor, an integrated pest management expert for the north coast of California. So far, the Virginia creeper leafhopper has been reported primarily in backyard and organic vineyards.
Western leafhoppers are common in California vineyards. Many are controlled by natural enemies. Whether the same will hold true for the Virginia creeper leafhoppers is unknown.

Fifth annual sheepdog trials in Hopland showcase dogs' skills

Dog handlers competed recently in the 5th Annual Sheepdog Trials, held on the rolling hills of the UC Hopland Research and Extension Center.
Sheepdog trials are held all over the nation, allowing dogs to accumulate points that count toward a national competition where the top 150 compete for the top spot, bragging rights, and possibly, for money-making opportunities that could include training or breeding, according to Bob Keiffer, superintendent at Hopland.
