After attending the 6th World Congress on Conservation Agriculture in Winnipeg, Manitoba, in June, Jeff Mitchell, UC Cooperative Extension specialist in the Department of Plant Sciences at UC Davis, and Kearney Agricultural Research and Extension Center, stated, "Focusing on soil care will improve soil water intake and storage...Reducing soil water evaporation can be achieved by preserving surface residues. Together these steps reduce energy use and greenhouse gas emissions – very important goals.”
Mitchell is the chair of the UC Conservation Agriculture Systems Innovation Center. CASI is exploring options to help support the implementation of conservation agriculture in California. Read more.
Conservation agriculture can result it greater efficiencies and better economics for California agriculture.
If I were in charge of a praying mantis' daily diet, I would enforce one stringent rule: "Please don't eat the pollinators! Do not, I repeat, target the bees or butterflies. Leave them alone!"
The mundane menu would include flies, gnats, stink bugs, aphids, mosquitoes, yellowjackets, grasshoppers, leaffooted bugs and not much else.
But since I'm not likely to be employed as the chef of a praying mantis' diet, these predators can--and do--eat what they want.
This morning I encountered a praying mantis perched on a Mexican sunflower (Tithonia) in our bee garden. He saw me. He swiveled his head about 180 degrees as he followed me with his five keen eyes--two large compound eyes and three smaller simple eyes. Hmm, not potential prey. He went about "praying"--bending his front legs and "assuming the position."
Okay, I thought. "Go catch a fly, gnat, stink bug, aphid, mosquito, yellowjacket, grasshopper or leaffooted bug."
So, what did he catch? A beautiful Western tiger swallowtail (Papilio rutulus) which made the fatal mistake of landing on his flower.
Yes, a praying mantis has to eat. Yes, he was hungry. Yes, it's nature. But why not a stink bug?
He polished off a butterfly.
"Yummy!" declared a colleague.

Say the word “wings” to folks who attend fairs and festivals and they may think of something to eat--buffalo wings or chicken wings.
But if you head over to McCormack Hall at the Solano County Fair, Vallejo, you'll be thinking of insect flight.
Flight of butterflies and moths. And maybe a ladybug or two.
Butterflies grace wall hangings, quilts and t-shirts and also appear in photographs and arts and crafts projects. You'll also encounter other bugs, including a moth (photograph), and a youngster's educational display board about spiders. (For those who aren't fond of spiders, these are illustrations.)
The 65th annual fair, themed "Cruisin' the County," opened Wednesday, July 30 and ends on Sunday, Aug. 3. The theme spotlights classic and unique cars.
Gloria Gonzalez, superintendent of the McCormack Hall building, and her crew have done a marvelous job setting up and displaying the many exhibits, which range from youth photos, preserved foods, and baked goods to quilts, special collections and arts and crafts projects.
Among the special butterfly and moth attractions we spotted:
- "Butterfly Lovers," a hand-and-machine quilted wall hanging by Tina Waycie of Vallejo
- "Butterflies," a needlepoint (stamped cross-stitchery) by Marlo Wilson of Vallejo, adult division
- "Butterfly T-Shirt," a textile project by Leslie Dunham of PACE Solano, adult division
- "Flying Wing," a machine-quilted wall hanging by Suzanne Ruiter of Fairfield, adult division
- "Moth," a photo by 9-year-old Maximilian Burgess-Shannon of Benicia
Gloria Gonzalez, a longtime 4-H leader (she's the co-community leader of the Sherwood Forest 4-H Club, Vallejo) kept busy finishing up the displays last Sunday. Among those assisting were Sharon Payne, past president of the Solano County 4-H Leaders' Council and the superintendent of the youth exhibit building at the Dixon May Fair; Gloria's daughter, Angelina Gonzalez, who leads the arts and crafts project for Sherwood Forest; and their colleague Iris Mahew of American Canyon.
Angelina, who recently received her master's degree in sociology from Sacramento State, is also the Solano County representative to the Statewide 4-H SET (science, engineering and technology) Program. (By the way, she's also a great cook--her caramel cookies won best of show.)
Fairs are all about informing, educating and entertaining--not necessarily in that order. They are a place where you can browse through the exhibit halls, enjoy the carnival rides, check out the 4-H and FFA livestock and the junior livestock auction, attend a free concert, and eat a bacon-wrapped hot dog. (Actually, I think something vegetarian sounds better!)
We're especially glad to see the insect-themed exhibits in McCormack Hall. It's not just vehicles that "cruise" the county or parts of the county.
Insects do, too.

Kearney Agricultural Research and Extension Center helps develop a sorghum feedstock program in California.
Pacific Ethanol, Inc., Chromatin, Inc., SCU Fresno's Center for Irrigation Technology and the University of California Division of Agriculture and Natural Resources received a $3 million matching grant for the California Energy Commission to collaboratively develop a sorghum feedstock program in California. This includes the California In-State Sorghum Program that facilitates California's production of low-carbon ethanol from Californian feedstock so that we can meet the state's renewable fuel and greenhouse gas reduction goals mandated by the federal Renewable Fuel Standard and the Californian Low-Carbon Fuel Standard.
Jeff Dahlberg, Ph.D., the director of Kearney Agricultural Research and Extension Center, is part of the UC Division of Agriculture and Natural Resources sorghum research group. Collaborative efforts of the group will be managed from KARE.

This week, Anthony Cornel, a UC Davis entomologist based at the UC Kearney Agricultural Research and Extension Center in Parlier, started a new mosquito surveillance and control program in Clovis. The goal is to abate populations of Aedes aegypti mosquitos, which appeared in the Clovis, Madera and San Mateo communities last year. The Ae. aegypti, which has the ability to spread the yellow fever, dengue fever and Chikungunya viruses, survived the winter and is now being actively tracked and eradicated by mosquito abatement officials in an effort to prevent Ae. aegypti from getting a strong foothold in California.
Cornel is working with Consolidated Mosquito Abatement District to deploy new inexpensive and safe "black bucket traps" that do not require power. Read more.
