If you see a black fly or its eggs and larvae while you're turning over your compost pile, don't be alarmed.
It's probably a "good soldier."
The black soldier fly (Hermetia illucens) is a beneficial insect. And a far-ranging one at that.
Martin Hauser, senior insect biosytemastist at the Plant Pest Diagnostics Branch, California Department of Food and Agriculture, says this is the only Hermetia he can find in the Sacramento region. "If you go south and to Arizona and New Mexico, you'll find more species, which are more colorful."
This New World species, he says, is now worldwide. "I found it in Nepal, Borneo, Australia,...

Warming streams could spell the end of spring-run Chinook salmon in California by the end of the century, according to a study by scientists at UC Davis, the Stockholm Environment Institute (SEI) and the National Center for Atmospheric Research (NCAR).
There are options for managing water resources to protect the salmon runs, although they would impact hydroelectric power generation, said UC Cooperative Extension associate specialist Lisa Thompson, director of the Center for Aquatic Biology and Aquaculture at UC Davis. A paper describing the study was published online recently in the

A lack of pollination by honey bees — brought on by increased insecticide use to control onion thrips — was linked to a sharp decrease in yields of California onion seeds, according to research published in the July-September 2011 issue of the University of California’s California Agriculture journal.
“Honey bee visits to onion flowers were negatively correlated with the number of insecticides applied per field and field size,” wrote the study’s authors, Rachael F. Long of UC Cooperative Extension in Yolo County and Lora Morandin of the Department of...

The University of California, Davis, is launching a new undergraduate major — “Sustainable Agriculture and Food Systems.” The program integrates several subjects to give students an understanding of the many issues facing contemporary farming and food systems, including production, processing, distribution, consumption, and waste management.
As noted in the Los Angeles Times, “With rising public interest in where our food comes from — as well as in "green" living — it makes sense that higher education would be eager to attract students who want to tap into the intersection between these two fields.”
