Who invited bugs to the UC Davis Picnic Day? Well, UC Davis officials and the UC Davis Department of Entomology and Nematology did! Yes! All systems are "go" for the 104th annual UC Davis Picnic Day, an all-day event on Saturday, April 21 when scores of visitors, aka picnickers, will stroll the...
elp the environment this Earth Day, which falls on Sunday April 22 this year, by installing insectary plants! These plants attract natural enemies such as lady beetles, lacewings, and parasitic wasps. Natural enemies provide biological pest control and can reduce the need for insecticides. Visit the new UC IPM Insectary Plants webpage to learn how to use these plants to your advantage.
Flowering insectaries also provide food for bees and other pollinators. There are both greater numbers and more kinds of native bees in fields with an insectary consisting of a row of native shrubs planted along the field edge (called a hedgerow). Native bees also stay in fields with these shrubs longer than they do in fields without them. Therefore, not only do insectaries attract natural enemies, but they can also boost crop pollination and help keep bees healthy.

The Siskiyou County Board of Supervisors has approved an artist's rendering of a mural that honors UC Cooperative Extension advisor and county director Steve Orloff, who passed away in late 2017, reported Danielle Jester in the Siskiyou Daily News. The mural also depicts Siskiyou County's agricultural heritage.
The mural will be painted on the south-facing wall of the UCCE office, a county owned building, said Rob Wilson, the UCCE advisor and director of the UC Intermountain Research and Extension Center who is serving as interim county director for Siskiyou County UCCE.
County resident Sari Sommarstrom said that, about a year before Orloff's passing, she contacted Orloff about the UCCE headquarters "boring building."
Orloff responded that, “Our office is not only boring, it is ugly.” Orloff pursued having a mural painted on the cooperative extension building's wall about 15 years before, but it never went anywhere.
Mount Shasta-based artist Kim Solga has been selected to paint the mural.
Earth Day has roots in California, stemming in part from an oil spill off the coast of Santa Barbara in 1969, wrote Rose Hayden Smith in a UC Food Observer post marking the 48th annual Earth Day this Sunday, April 22.
"The Santa Barbara oil spill galvanized U.S. Senator Gaylord Nelson (D-Wisconsin) to call for a national day of locally inspired and organized 'teach-ins' on the environment – a national 'Earth Day,'" the story says. The first Earth Day was April 22, 1970.
Earth Day is widely credited with “sparking” the modern environmental movement. Landmark environmental legislation swiftly followed (including the Clean Air Act, Clean Water Act and Endangered Species Act). The Environmental Protection agency was founded that same year. Twenty years after its launch, Earth Day became a global movement.
Among the stories covered in the UC Food Observer is a UC Cooperative Extension research project that is seeking to identify street trees that can cope with rising temperatures and lower rainfall expected due to climate change. UCCE scientists are partnering with the U.S. Forest Service “in an unprecedented 20-year research study to expand the palette of drought-adapted, climate-ready trees for several of the state's climate zones."
The UC IPM program is encouraging Californians to celebrate Earth Day by growing insectary plants. These plants attract natural enemies such as lady beetles, lacewings, and parasitic wasps. Natural enemies provide biological pest control and can reduce the need for insecticides.
