“The war is over—again,” wrote reporter Pat Brennan of the Orange County Register in a news article published Aug. 14.
Brennan was referring to the war against the Mediterranean fruit fly, a tiny pest that targets some 260 crops. The pest, first detected inCaliforniain 1975, prefers such hosts as peach, nectarine, apricot, avocado, grapefruit, orange and cherry. It is considered the world's worst agricultural pest.
California State Department of Agriculture had earlier announced the eradication of the medfly in three counties:Los Angeles, Solano andSanta Clara.If it were to become permanently established in California, the medflycould cost the state $1.3 to $1.8 billion in annual losses, estimated CDFA Secretary A. G. Kawamura.
I remember whenSolanoCountyag officials discovered four live medflies in a single trap in downtownDixon. The date: Monday, Sept. 10, 2007. Newspapers bannered the story. A quarantine ensued. Farmers fretted, and rightfully so. Later I attended a press conference at theNutTreeAirport, Vacaville;a pilot had just released the first of many millions of sterile male fruit flies over Dixon. He showed us the sterile medflies, dyed pink.
The sterile flies mate with wild flies and biologically force wild populations out of existence, the CDFA says.
UC Davis entomologist James Carey, who has published widely on the medfly, said the pest has been multiplying and spreading undetected--like cancer--for years in California. He says it’s never been really eliminated and he questions whether it could ever be eradicated.
CDFA and Solano County ag officials said no; that an errant tourist likely brought it to Dixon on a piece of fruit fromHawaii. The medfly lays its eggs inside fruit.
Medfly wars ensued.
Carey shared an email he sent Aug .14 to Brennan:
“The absence of medfly appearances anywhere else in the continental U.S. besides California over the past two decades strongly supports the argument that the medfly has never been completely eradicated in our state. CDFA's efforts at eradication have been successful at driving the populations back to subdetection levels for a few years. However, the reappearances of the medfly in the same cities and even in the same locations within these cities is due to a long-term established population. Although I fully acknowledge the need to respond to the medfly when it appears in the state as it did last year, I have no reason to believe that this program will have been any more successful than the previous ones which merely suppressed rather than eliminated the medfly population from the state."
“This recent declaration of eradication is around the 50th emergency response to medfly outbreaks over the past two decades by CDFA, virtually all of which have been in the same general locations. To my knowledge during this same period no other state such as Arizona, Florida or Texas has experienced any outbreaks even though these states, like California, have climates suitable for the medfly establishment and have many tourists and migrants who are capable of introducing the medfly. These states have experienced no outbreaks while California has experienced 50.”
The CDFA Web site says medflies are not established in California.
"These (medflies) and other exotic pests have not become established in California due to (1) strict federal exterior and state interior quarantines, (2) a pest detection program, and (3) aggressive eradication programs when an infestation is discovered."
Carey, who has plotted all medfly finds in California, says medfly populations “do not really get going until late summer and fall. Stay tuned for this fall.”
One thing is certain: the little bugger draws a lot of attention. That’s because, as Brennan wrote, it “attacks so many crops.”

“I’ve got black bumblebees buzzing around our backyard like crazy,” the caller said. “They’re loud. Very loud. They’re dive-bombing and scaring the cat and dog. I’ve never seen anything like this before.”
The unwelcome visitors were not bumblebees. They were carpenter bees.
Carpenter bees? No, they don’t know how to read blueprints or frame floors and walls. They nest in weathered wood, like your fence posts, utility poles or firewood. They tunnel into your deck, railing, shingles and shutters.
They are pests. But they’re also pollinators.
Native pollinator specialist Robbin Thorp, professor emeritus at the UC Davis Department of Entomology, fields many calls about carpenter bees.
This one pictured below is a male carpenter bee, Xylocopa tabaniformis orpifex Smith NB, Thorp says.
“It is stealing nectar from the base of the flower. They also spend a lot of time cruising around chasing everything that enters their territory.”
Contrary to popular opinion, carpenter bees don’t consume wood. If you don’t want them around, paint or varnish your wood. You can also plug their (unoccupied) holes with steel wool or caulk, or screen the holes so they don’t return.
The female and male carpenter bees that nectar the salvia (sage) in our bee friendly garden are about the size of bumblebees. “Robust” comes to mind. Okay, fat. They’re fat.
Their abdomens are bare and a shiny black. If you photograph them, you’ll see your own reflection. It’s like seeing your reflection in a black Lamborghini.
The female carpenter bees are a solid black, while the male carpenter bees are lightly colored around the head.
In comparison, bumblebees have hairy abdomens with at least some yellow markings.
If I were a carpenter and you were a…nah, I’d rather be a bumblebee./o:p>/o:p>/o:p>/o:p>/o:p>/o:p>/o:p>/o:p>/o:p>/o:p>/o:p>/o:p>/o:p>/o:p>/o:p>/o:p>/o:p>/o:p>/o:p>/o:p>/o:p>

Ouch! So, you’ve been stung by a bee.
If you’re a beekeeper, an occasional sting is a natural part of beekeeping.
UC Davis apiculturist Eric Mussen says that the average beekeeper may be stung approximately 3000 times a year.
Mussen describes the sting as a “modified egg-laying apparatus, so only females can sting.” The queen bee can sting multiple times, while the female worker bee dies after stinging. Drones, or male bees, cannot sting. (Interesting that Jerry Seinfeld, who played the role of Barry B. Benson in The Bee Movie, could sting! Then again, he was a "pollen jock," too. However, only the worker bees (females) gather nectar and pollen.)
When bees sting, they inject a venom that can be temporarily painful. The pain may last a few minutes but may be felt up to a few days later.
How do you remove the stinging apparatus? “It doesn’t matter how you get it out as long as you remove it as soon as possible, within 45 to 60 seconds,” Mussen says. “Otherwise, venom will keep pumping into the body.”
He advises victims to "pull out or scrape off the sting (which some people call a “stinger”) with a fingernail. The sting is barbed. The sting also emits an alarm pheromone that marks the target for additional stings. Leave the area quickly.”
Some advise that you wash the wound and treat it with ice or a cold compress to alleviate the pain. Or, apply an aerosol or cream antihistamine preparation that contains a skin coolant. The important point: don’t scratch the itch as that could lead to an infection, Mussen says.
If you’re stung on the neck or mouth, or start feeling severe symptoms, you should seek medical attention immediately, he says.
Allergic responses include hives, swelling, nausea, vomiting, abdominal cramps and headaches. Life-threatening reactions—which require immediate medical intervention—include shock, dizziness, difficulty in breathing, unconsciousness, and a laryngeal blockage resulting from swelling in the throat.
“Only about one or two people out of 1000 are allergic or hypersensitive to bee stings,” the UC Davis apiculturist says.
To avoid being stung:
- Wear long pants and a long-sleeved shirt.
- Wear light-colored clothing. Bees are more likely to sting black or red objects.
- Don’t wear perfume, cologne or scented soaps.
- Avoid going barefoot.
- Remain calm if you’re stung. Don’t flail your arms at the bee; movement attracts more stings.
- Remove bees from a swimming pool before entering the pool.
I've always loved the wit and wisdom of insect-inspired poets.
God in His wisdom made the fly
And then forgot to tell us why.
We hope that, when the insects take over the world, they will remember with gratitude how we took them along on all our picnics.

If you look at the world through a viewfinder--as I have a habit of doing--it’s a wonderful, exquisite place, especially if you capture critters in their natural habitat. They don’t complain when you make them look fat, skinny, nice or ferocious.
Blow flies, honey bees, carpenter bees, spotted cucumber bees, the ten-lined June beetle, and mosquitoes all appear in my viewfinder. Okay, I know. We’re not supposed to like some of these pests (such as the carpenter bees, spotted cucumber bees and the ten-lined June beetles), but hey, all of them are pretty enough to sing the national anthem at the Olympics.
Photography, or writing with light, is just that. Writing with light. Back before the digital technology age, we used to process film, make prints and then hang them out to dry. We "pho-togs" marinated ourselves in Dektol, DK-60 and Hypo.
Our "pheromone" wasn't always appreciated. But the images were.
But the images were.

When the California State Fair, Sacramento, opens Friday, Aug. 15 for an 18-day run, don't miss "California's Gold" and "Nature's Gallery" in the UC Davis Centennial Pavilion (Building 3).
The 6,000-square-foot pavilion will showcase what the university is all about, from its toddler stages to its teenage years to today. It's the university on parade, with one million visitors vying for curbside seats.
What are "California's Gold" and "Nature's Gallery?" Think insects. Think art. Think of a fusion of science and arts. In fact, both projects are part of the UC Davis Art/Science Fusion Program, directed by UC Davis entomologist Diane Ullman and artist Donna Billick. It's a program where students merge with faculty, staff and community members to create art.
"California's Gold" is a 3x5-foot ceramic mosaic of the state, depicting California's flora and fauna, including the California poppy, quail, trout and salmon, as well as some of our major agriculture crops--dairy cows, honey bees, almonds, grapes, garlic and olives.
"Nature's Gallery" is a spectacular mosaic mural depicting plants and insects on ceramic tiles. (Note that not all of the massive "Nature's Gallery" will be there; just a part of it.) The exhibit drew 300,000 visitors when it was displayed last summer at the U.S. Botanic Garden on the Capitol Mall, Washington, D.C. Eventually the work will be installed in the Ruth Storer Garden, UC Davis Arboretum.
"California's Gold" is going places, too. Following its display at the Aug. 15-Sept. 1 state fair, off it goes for temporary display in Cong. Mike Thompson's office in Washington, D.C.
Ullman and Billick said UC Davis students' creative energy and talents sparked both "California's Gold" and "Nature's Gallery," but we all know that Ullman and Billick are the driving forces. They are amazing innovators who fuse science with art and make their projects both fun and creative. They founded the Art/Science Fusion Program, which is housed in Science and Society, UC Davis College of Agriculture and Environmental Sciences.
So, it's not surprising that Ullman, an entomology professor and associate dean for undergradaute academic programs at the College of Agricultural and Environmental Sciences, received a top faculty award this year: the 2008 Chancellor's Achievement Award for Diversity and Community.
Ullman creates communities of learning, said Rahim Reed, associate executive vice chancellor for Campus Community Relations, and she encourages students "to learn in creative ways, discover new careers, and engage in their campus and community."
Very well said. Very well said, indeed.
See you at the fair!
