Have you seen big green beetles in your California yard or garden? Or beetles feeding on your roses or other plants? There are many kinds of beetles commonly found in our landscapes, but the Japanese beetle is not one of them.
Japanese Beetles
Many people think they've seen the Japanese beetle, a small scarab beetle with metallic green wings with white spots on the margins. However, Japanese beetles are generally not found in California.
The Japanese beetle is an exotic and potentially invasive pest for which the California Department of Food and Agriculture (CDFA) is conducting eradication efforts to limit its spread...

The event was recently held at the University of California's Agricultural and Natural Resources South Coast Research and Extension Center (SCREC) in Irvine, CA.

[From the May 2017 issue of the UC IPM Retail Newsletter]
Retail nursery and garden center employees play an important role in communicating pest management information to gardeners and the public. The UC Statewide IPM Program (UC IPM) strives to help retailers stay current on emerging pest-related topics facing California that help consumers effectively manage pests.
As part of this effort, UC IPM partnered with several UC Cooperative Extension Advisors and Specialists to offer three regional train-the trainer workshops in 2016 and early 2017. A total of 188 participants from 41 retail...

What are those white, frothy masses you see on your rosemary, salvia, lavender, or other plants? Spittlebugs. The masses of froth can be found on plant foliage, cones and stems.
Inside the foamy mass you will find immature spittlebugs feeding on plant tissue. Adult spittlebugs (also called froghoppers) can also be found on the plant, and are ¼ of an inch long, and green or brown.
Although not aesthetically pleasing, occasional masses of spittlebug generally do not harm established woody plants.
The best way to deal with spittlebugs is to wash them off with water, ignore them, or handpick the bugs. Pesticides are not usually effective or needed and can cause harm to pollinators that often visit these...

The following press release was distributed on April 13, 2017 by the Citrus Pest & Disease Prevention Program.
Huanglongbing was confirmed in a single citrus tree in the City of La Habra in Orange County on April 11. This new find will result in a new HLB quarantine area, which will link the existing quarantines into a contiguous zone spanning portions of Los Angeles and Orange counties.
Additionally, two samples of Asian citrus psyllids in Anaheim tested positive for carrying the bacteria that causes HLB. These lab results were confirmed last week, and the California Department of Food and Agriculture is treating host plants in the surrounding 800-meter area. No...
