UC Davis entomology graduate student Kevin Rayne Cloonan not only won a coveted award for his research presentation at the 60th meeting of the Entomological Society of America in Knoxville, Tenn., but it may prove to be a boon to California almond growers.
Cloonan, who is studying for his master’s degree with chemical ecologist Walter Leal, professor of entomology, won a second-place award for his insect repellent research on the navel orangeworm (NOW), a major pest of California’s almond industry.
His talk was part of the 10-minute graduate student presentations.
Cloonan presented his paper on “Potential Oviposition Repellent for the Navel Orangeworm (Amyelois transitella) in Almond Orchards of Central California.” For his research, he tested 20 broad spectrum insect repellents as potential oviposition repellents. Bedoukian Research Inc. developed the repellents.
Cloonan's work involved electrophysiological recordings, laboratory behavioral assays, and a field behavioral assay. He first used electroantennogram (EAG) assays to identify which of those 20 repellents the female antennae could detect. Of the 20 repellents, three showed significant EAG responses, he said.
In testing the oviposition repellency under laboratory conditions with laboratory populations, he found that two of the three repellents showed significantly reduced oviposition; they were then tested with field populations in almond orchards in Arbuckle.
“One especially looks very promising,” said Cloonan, adding “I couldn’t have done this research without the support and help of Dr. Leal and everyone in the Leal lab.”
Cloonan has been asked to present a poster at the Almond Board of California conference, to be held Dec. 11-13 at the Sacramento Convention Center.
At the ESA meeting, Cloonan’s presentation was one of 14 vying for top honors in the Plant-Insect Ecosytems (P-IE) Section. The P-IE Section includes behavioral, ecological, and evolutionary relationships in natural landscapes, as well as integrated pest management (IPM) in agriculture, horticulture, forests, and lawn and garden. The section also deals with aspects of crop protection, host-plant response, plant pathology/vectors, pollination, biological control, microbial control, and others.
Cloonan, who plans to pursue his doctorate in entomology, is a graduate of the University of Idaho, with a bachelor's degree in entomology.
Almonds are big business in California and getting bigger.
The National Agricultural Statistics Service forecasts California’s 2012 almond crop at a record-breaking 2.10 billion meat pounds, valued at approximately $3 billion. Eighty-percent of the global supply of almonds is grown in California, and about 70 percent of California’s crop is marketed overseas.
Honey bees from all over the country are trucked to California to pollinate the state’s 780,000 acres of almonds, which begin blooming in mid-February, around Valentine's Day. Two bee colonies are required to pollinate each acre--and that's a lot of bees!

The ESA Governing Board today announced the new fellows, who will be recognized Nov. 11, 2012 at the ESA’s annual meeting in Knoxville, Tenn.
Page, the vice provost and dean of the College of Liberal Arts and Sciences, Arizona State University, Tempe, since July 2011, is a pioneer in the field of evolutionary genetics and the social behavior of honey bees.
Page did much of his research at UC Davis. He received his doctorate in entomology at UC Davis in 1980, learning from his major professor Harry H. Laidlaw Jr. (for whom the UC Davis bee research facility is named). He then joined The Ohio State University faculty before returning to UC Davis as a faculty member in 1989.
He chaired the UC Davis Department of Entomology from 1999 to 2004.
Page, who studies the evolution of complex social behavior in honey bees, from genes to societies, left UC Davis in 2004 to be the founding director of the new School of Life Sciences. Arizona State University, where he built a Social Insect Research Group that is now recognized worldwide.
Page was trained as an entomologist, evolutionary population geneticist, classical animal breeder, and mechanistic behaviorist, according to a news release issued by the ESA. "This training has defined his research approach of looking at the genetics and evolution of complex social behavior. He has taken a vertical approach to understanding the mechanisms of honey bee social foraging and how it evolves."
His work is contained in more than 225 research articles. Page has also co-edited three books and authored or co-authored two. Page is a highly cited ISI (Institute for Scientific Information) author in plant and animal science. He is a fellow of the American Association for the Advancement of Science (AAAS) and an elected member of the American Academy of Arts and Sciences, the German National Academy of Science, and the Brazilian Academy of Science. In 1995 he was awarded the Alexander von Humboldt Research Prize by the government of Germany.
Although Page resides in Arizona, his research bees are UC Davis-based residents. Bee breeder-geneticist Michael “Kim” Fondrk, who worked with Page at Ohio State University, UC Davis and ASU, manages the specialized genetic stock, which today includes 90 hives.
Of the 90 hives, about 70 have instrumentally inseminated queens as part of their pollen-hoarding breeding research program.
Back in 2006, Page told us: "Davis is still home to me. I raised my family there, my closest friends and colleagues are still in the entomology department there. I still feel very strong attachments.”
Former department chair Robert Washino remembers him fondly. He recently recalled that "Rob chose to return to UC Davis in 1989 to be with his former major professor (Harry H. Laidlaw Jr.). He later cared for him and his wife, Ruth, in their declining years. We all remember Rob’s scholarly side and his humanitarian side.”
Page joins three other UC-affiliated entomologists in the ESA Fellows Class of 2012: Joseph Morse, professor of entomology at UC Riverside; Henry H. Hagedorn, who received his doctorate in entomology from UC Davis in 1970; and R. Michael Roe, who trained at the UC Davis Department of Entomology from 1981 to 1984 as a National Institutes of Health fellow in cellular and molecular biology.
And interestingly enough, Page is following in the footsteps of Harry H. Laidlaw Jr., who himself was elected an ESA fellow in 1991.
With the addition of Page, the UC Davis Department of Entomology now has 16 fellows who are current or former faculty members. The first was Richard M. Bohart (1913-2007), for whom the Bohart Museum of Entomology is named. He received the honor in 1947. Fifteen others followed: Donald McLean, elected in 1990; Harry H. Laidlaw Jr. (1907-2003), 1991; John Edman, 1994; Robert Washino, 1996; Bruce Eldridge, 2001; William Reisen, 2003; Harry Kaya, 2007; Michael Parrella and Frank Zalom, 2008; Walter Leal, 2009; Bruce Hammock and Thomas Scott, 2010; James R. Carey and Diane Ullman, 2011, and now Robert E. Page Jr., 2012.

There's a good reason why they're called "the menace in the mattress." The mattress is one of their hiding spots.
They? Bed bugs. Parasites that feed on human blood.
"Bed bug infestations are rampant locally, nationally and globally," says Tanya Drlik, integrated pest management (IPM) coordinator of Contra Costa County who will speak at the May 3rd meeting of the Northern California Entomology Society, to be held in the Harry H. Laidlaw Jr. Honey Bee Research Facility on Bee Biology Road, UC Davis.
“We’ve had a reprieve from bed bugs for about 50 years, but now they’re back,” said Drlik, who will discuss “The Resurgence of Bed Bugs and Current Effective Control Methods” at 9:45 a.m. in the Laidlaw conference room.
The society (membership is open to everyone) will meet from 9:15 a.m. to 2:30 p.m. Drlik is one of five speakers on topics ranging from bed bugs to lacewings to endangered species.
Drlik, who formed the Bed Bug Task Force to help prepare Contra Costa County to meet the challenges of the mounting bed bug infestation, says that bed bugs “have no regard for wealth or class—everyone is vulnerable. Bed bugs can be found all across the country in apartment buildings, hotels and motels, private residences, hospitals, waiting rooms, fire station, taxis and buses…and the list goes on. They’ve infested four-star hotels and penthouses as well as homeless shelters and rundown apartment buildings.”
“Judging by history and the experience of other jurisdictions across the country, the problem is only going to increase, and more and more public buildings and homes will experience infestations,” said Drlik, who has a master’s degree in ecosystem management and nearly 40 years of experience in the field of IPM.
“Bed bugs are difficult to control because of their small size, their secretive nature and their growing resistance to the pesticides we have at our disposal. Poverty, clutter, and poor housekeeping do not cause bed bug infestations, but they make eliminating infestations much more difficult.”
Bed bugs “can be seen in epidemic proportions in some areas of the United States, including New York City and central and southwestern Ohio,” said Drlik, adding that since 2004, New York City has experienced a 2277 percent increase in complaints about bed bugs in the five boroughs (source: New York City Department of Housing Preservation and Development). “Colleagues in the Franklin County Health Department in central Ohio have commented to us that they were completely unprepared for the rapidity with which bed bugs spread throughout their county.”
Other topics at the Nor Cal Entomology Society meeting include:
- “Protecting Invertebrates Listed as Threatened or Endangered Species in California” by Darlene McGriff, California Natural Diversity Database (California Department of Fish and Game).
- “California Forest Insect Conditions Going into 2012” by Cynthia Snyder, U.S. Forest Service, Shasta-McCloud Management Unit.
- “PG&E’s Use of Safe Harbor Agreements and Programmatic Permits to Protect Endangered Organisms on Utility Rights of Way” by Peter Beesley, PG&E.
- “In-Depth Look at Lacewings, an Augmentative California Biological Control Agent” by Shaun Winterton, California Department of Food and Agriculture Biological Control Program.
All great topics, to be sure. Bed bugs, however, are the big draw, in more ways than one.
We remember an Entomological Society of America (ESA) seminar on these bloodsuckers that resulted in a flurry of inspections back in the hotel rooms: mattress, baseboard, furniture, closet and luggage checks.

Oh, sure, there are lots of bug girls and bug boys out there--bug women, bug men and real insects, too--but there's only one Bug Girl.
She's the one who writes that witty/informative/tell-it-like-it-is-not-what-you-want-it-to-be bug blog called...drum roll...Bug Girl.
Bug Girl, aka Bug C. Membracid, spoke at a social media seminar at the 59th annual meeting of the Entomological Society of America, held Nov. 13-16 in Reno.
Before her talk, folks were sporting "I Am Bug Girl" stickers on their name tags. That added to the mystery of "Who is Bug Girl?" That one? This one? The one over there? Will the real Bug Girl please stand up?
See, she writes anonymously. We don't know who she is--she keeps her identity a secret--but we do know she has a doctorate in entomology from North Carolina State University and she works in a provost's office "in a Connecticut university."
We also know she wears a mop of hair the color of a blue morpho butterfly and some cool (and mostly erect) blue antennae--at least she did at the ESA meeting. We also know she has a fan base like you wouldn't believe. Fellow bug lovers were coming out of the woodwork like termites to hear her speak, hug her, and to be photographed with her.
Move over, Angelina Jolie. Take a seat, Taylor Swift. Scoot, Jennifer Aniston. We have a scientist in our midst!
In her talk, "Adventures of Bug Girl or Everything You Wanted to Know About Entomological Social Media But Were Afraid to Ask," she told how you, too, can become "an online entomology goddess." She began blogging as Bug Girl in 2004, as "a way to become a better writer."
Bug Girl writes the way she talks. No academic jargon, nothing you have to read three times to understand. "it's about talking to people; it's about conversation, not lecturing," she said.
However, Bug Girl warned "people can be very cruel to you." Someone even set up a website countering her views, she said.
She also mentioned her bug-blogging buddies, including Dragonfly Woman, Alex Wild (he received his doctorate in entomology from UC Davis) and Carl Zimmer, among others. "I don't see us as competitors, but as collaborators," she said. "It's not about who has the most followers."
"What I do isn't so much as public outreach; it's public engagement. It's having a conversation with our readers."
Bug Girl said she's proud of what she called "the little victories," like convincing Nature journal to spell "bed bug" as two words, instead of one. She bashes bad science like some folks bash cockroaches.
Bug Girl hammered home several pieces of advice:
1. Find your niche or what she called your "blue water" or where few are--and not "red water," because that's where the sharks are.
2. Find your voice and make it distinct. Don't look for validation or positive validation.
3. Develop a thick skin.
4. Be prepared to spend a lot more time and energy than you expect.
5. Don't expect a profit.
For all bloggers and would-be bloggers, Bug Girl recommended folks read David Meerman Scott’s The New Rules of Marketing and PR.

Until recently, praying mantids were thought to be deaf. We now know that 65 percent of all mantid species can hear. Where do the tympanal organs occur in mantid species?
The answer: The two tympanal membranes face one another inside a narrow groove between the metathoracic legs (hind legs).
That was just one of the questions asked at the 2011 Linnaean Games, a traditional part of the annual meetings of the Entomological Society of America (ESA). It's a spirited college-bowl type of game in which students respond by ringing a bell and shouting out the answers. The winning team receives a huge trophy--and bragging rights.
The UC Davis Linnaean Team, fresh from winning the ESA Pacific Branch championship, journeyed to Reno to compete in this year's Games. Like the other branch winners, UC Davis was there not just to compete, but to have fun and enjoy the camaraderie.
Fun, they did. For the occasion, emcee Tom Turpin, professor of entomology at Purdue, wore his trademark butterfly bow tie. His sharp eyes quickly noticed the bright red bow tie of UC Davis graduate student Matan Shelomi.
So Turpin leaves the podium and walks over to Shelomi to congratulate him on his fashionable choice of ties. The audience erupts into applause.
Then, let the Games begin! When it was all over, the University of Nebraska took home the trophy.
In the championship game, pitting Nebraska against North Carolina State, it was touch-and-go for awhile until Nebraska pulled solidly ahead.
Think you can answer some of the questions? Give them a try. (Answers below)
1.If you donate blood, you are asked about your exposure to babesiosis. What is the common name of the arthropod group that is the main vector of this disease?
2. What is the term for the separation of the cuticle from the epidermis during molting?
3. What does acuminate mean?
4. What is the common and scientific name of the beetle described by LeConte that is a significant pest of corn and was introduced into Europe in the 1990s. The larvae feed on corn roots.
5. What is the meaning of rugose?
6. Most ants use chemical trailing to navigate to and from the nest. However, as a result of high winds and blowing sand, ants that inhabit dessert environments use a different mechanism. How do desert ants find their way?
7. What is the name of insecticidal extract derived from dried chrysanthemum flowers and what chemical is typically added as a synergist to help the performance of this material?
3. Tapering to a long point.
4. Western Corn Rootworm (Diabrotica virgifera virgifera)
6. They have the ability to count steps. A recent study experimentally altered the length of ant legs after their search for food. They found that ants with longer legs overshot the nest while ants with their legs shortened didn’t go all the way back to the nest. They then placed all the ants in the nest, and the next day all ants went out in search of food and came exactly back to the nest, showing that desert ants have some kind of pedometer.
