Mosquitoes will take the spotlight, front line and center, this month.
On Wednesday, April 8, Regents Professor Michael Strand of the University of Georgia, Athens, and internationally recognized for his research on parasite-insect host interactions, will speak on "The Role of Microorganisms in Growth, Development and Reproduction of Mosquitoes” at the UC Davis Department of Entomology and Nematology seminar from 12:10 to 1 p.m. in 122 Briggs.
Next the Pacific Branch of the Entomologist Society of America (PBESA) will honor medical entomologist Thomas W. Scott, distinguished professor of entomology, UC Davis Department of Entomology and Nematology, at its 99th annual conference, April 12-15, in C'ouer d'Alene, Idaho. He will receive the coveted C. W. Woodworth Award for his outstanding work on dengue, a mosquito-transmitted disease.
And then on Friday, April 24, UC Davis will co-host the fourth annual Bay Area World Malaria Day Symposium, set from 8 a.m. to 4 p.m., Friday, April 24 on the Clark Kerr campus, UC Berkeley. UC Davis and Zagaya, a non-profit organization that envisions a malaria-free world, are partnering on the project.
Michael Strand Seminar April 8
Professor Strand's talk is much anticipated. "Mosquitoes are well recognized as the most important arthropod vectors of disease-causing pathogens," Strand says in his abstract. "Interest in the gut microbiota of mosquitoes has risen recently as a potential tool for manipulating vector competency. In contrast, much less is known about the role of this community in mosquito growth, development and reproduction. In this talk I will discuss recent results from our lab group regarding the composition of the gut microbiome in different mosquito species and insights we have gained about the function of this community in mosquito biology and evolution."
Strand focuses his research in the areas of parasite-host interactions, virology, immunity and development. Current projects center on virus-host interactions, function of the insect immune system, and regulation of reproduction in mosquitoes and other insects.
Strand will be introduced by molecular biologist Shirley Luckhart, professor in the Department of Medical Microbiology and Immunology School of Medicine, and co-director of the UC Davis-based Center for Vector-borne Diseases (CVEC).
Talk will turn to dengue at the PBESA meeting in Co'eur d'Alene, Idaho. Professor Scott, who has researched mosquito-borne disease for 35 years and is retiring in June, is a global authority on the epidemiology of mosquito-borne disease, mosquito ecology, evolution of mosquito-virus interactions, and evaluation of novel products and strategies for mosquito control and disease prevention. Among the top vector biologists in the world, he is recognized as the leading expert in the ecology and epidemiology of dengue.
Scott is known for his holistic and comprehensive approach in finding solutions to protect the world's population from dengue, a disease that infects some 400 million per year. Some 4 billion people in 128 countries, more than half of the world's population, are at risk for dengue. Currently no vaccine or drug is effective against this life-threatening disease.
Scott's most significant research contributions concern the ecology and epidemiology of dengue:
- Blood feeding behavior, longevity, dispersal, and vector-virus interactions of the mosquito Aedes aegypti;
- Longitudinal cohort studies of spatial and temporal patterns in human dengue virus infection in Peru and Thailand; (dengue research in Peru, Thailand, Puerto Rico and Mexico for the past 25 years)
- Impact of human movement on mosquito contact rates and spatial dimensions of dengue virus transmission; and
- Mathematical and computer simulation modeling of mosquito population biology and mosquito-borne pathogen transmission.
Scott co-founded the Center for Vector-Borne Research (CVEC), comprised of researchers throughout the UC System. See more information on Scott.
Patrick Duffy, chief of the National Institutes of Health's Laboratory of Malaria Immunology and Vaccinology, will keynote the fourth annual Bay Area World Malaria Day Symposium, set Friday, April 24 on the Clark Kerr campus, UC Berkeley. The symposium, to take place from 8 a.m. to 4 p.m., will be co-hosted by UC Davis and Zagaya.
Duffy is an internationally recognized expert in human malaria pathogenesis, malaria in pregnancy, and malaria vaccine development. He has published more than 100 papers on malaria over his nearly 25-year career.
UC Davis co-host Shirley Luckhart, professor in the Department of Medical Microbiology and Immunology School of Medicine, and co-director of the Center for Vector-borne Diseases, will be one of the speakers.
Meanwhile, take a look at the spectacular mosquito images taken by entomologist/photographer Jena Johnson of Athens, GA (she is married to Michael Strand). This is the Aedes aegypti mosquito blood-feeding on her.

With your camera!
If you're into pollinators, plants and photography, and want to share your work nationally, here's a new project for you.
To generate some buzz for pollinators, the Center for Food Safety (CFS) is partnering with the Wild Bee Gardens app to sponsor a national photography contest.
Bay Area native bee enthusiast Celeste Ets-Hokin, who launched the Wild Bee Gardens app (with identification assistance from consultants, including native pollinator specialist Robbin Thorp, distinguished emeritus professor of entomology at the University of California, Davis), alerted us to the contest.
It is "designed to raise awareness about the dazzling diversity of North America's native bees and other pollinators," she said, "and to engage residents from coast to coast in the vital and rewarding business of creating a continental tapestry of wild bee gardens,"
The winning photographs will be published in the Wild Bee Gardens app, and also promoted on the CFS website, Facebook and Twitter pages.
CFS, headquartered in Washington, D.C., with branch offices in San Francisco, Honolulu and Portland (Ore.) describes itself as "a national non-profit public interest and environmental advocacy organization working to protect human health and the environment by curbing the use of harmful food production technologies and by promoting organic and other forms of sustainable agriculture. CFS also educates consumers concerning the definition of organic food and products."
Judges will choose numerous winners, and each will receive a free Wild Bee Gardens app to keep, or give as a gift, "so that you can share your enthusiasm for wild bees and their gardens with your friends and families," Ets-Hokin said. Winners also will receive a pollinator swag bag from CFS.
Want to learn more about the submission guidelines and selection criteria? Access http://centerforfoodsafety-wildbees.tumblr.com . The deadline to submit photos is April 17.
If you can't identify the pollinator, not to worry. After the judges select the winners, Thorp will identify the bees. He's a co-author of California Bees and Blooms: A Guide for Gardeners and Naturalists (Heyday), along with colleagues Gordon Frankie, Rollin Coville and Barbara Ertter. Thorp also co-authored Bumble Bees of North America: an Identification Guide (Princeton University Press).
Speaking of bumble bees, they seem to be quite scarce this year. We saw our first black-tailed bumble bee (Bombus melanopygus) of the season on March 15 on Spanish lavender in Vacaville.

She's a butterfly magnet.
When Oakland parks supervisor Tora Rocha, known as "The Monarch Queen" and "The Butterfly Whisperer," (she rears monarchs and encourages everyone to do so), visited the Häagen-Dazs Honey Bee Haven at the University of California, Davis, on Thursday, butterflies seemed to float in from everywhere!
The Western Tiger Swallowtail, Painted Lady, Gulf Fritillary and even the Cabbage White fluttered around her head.
But that Western Tiger Swallowtail...that newly emerged Western Tiger Swallowtail...
Aglow in yellow and fringed with black, it headed over to the Verbena to sip some flight fuel: sweet nectar. A brisk wind threatened to dislodge its hold but it refused to budge from its buffet.
The Häagen-Dazs Honey Bee Haven is the UC Davis Department of Entomology and Nematology's half-acre bee friendly garden on Bee Biology Road. Planted in the fall of 2009, it is located next to the Harry H. Laidlaw Jr. Honey Bee Research Facility, west of the central campus. (See history of the bee garden.)
And on Saturday, May 2 there will be a fifth anniversary celebration from 10 a.m. to 2 p.m. You're invited! (Yes, it's free and open to the public.) You'll see bee observation hives and beekeeping demonstrations. You'll learn what to plant for bees. Bee scientists will show you how to observe and identify bees, and show you native bee condos, also called "bee hotels" or "bee houses."
Besides the honey bees, bumble bees, sweat bees, carpenter bees and other pollinators, there's a good chance you'll see such butterflies as the Western Tiger Swallowtail (Papilio rutulus) sailing over the state-of-the-art fence that Eagle Scout Derek Tully and his assistants crafted.

Ah, soapberry bugs...
They'll never get top billing in a racy novel, let alone star in an R-rated movie.
The "R" word comes into play only when they're referred to as "the rapidly evolving soapberry bugs" or when scientists talk about reproduction.
Evolutionary ecologist Scott Carroll of the UC Davis Department of Entomology and Nematology is a soapberry scientist. In fact, he is the "resident soapberry scientist" behind the spectacular website, "Soapberry Bugs of the World." Scott, who holds a doctorate in biology from the University of Utah, directs the UC Davis-based Institute for Contemporary Evolution, which "observes and experiments with patterns of ongoing evolution in wild and anthropogenic environments."
Explore the soapberry website--it's the work of Carroll, Crystal Perreira and Trevor Fowels--and you'll learn all about these insects.
"Small but powerful, soapberry bugs are quickly adapting as humans alter the world," Carroll writes on the website. "These beautiful insects artfully show how evolution happens every day and why it matters."
"Here at soapberrybug.org, we are collecting and integrating the world's information on all 65 species of soapberry bugs. We present this information in a variety of formats accessible to students, scientists, and anyone with interest."
Soapberry bugs belong to the order Hemiptera, often known as the true bugs. "Their lack of relatively well-developed scent glands places them in the family Rhopalidae," Carroll says. "Soapberry bugs specifically encompass all species within the subfamily Serinethinae. Serinethinae contains three genera: Jadera, Leptocoris, and Boisea."
They encourage you to check out their website:
• Comics, videos, and photos
• Identification guides
• Research results and scientific papers
And if you see soapberry bugs, you're welcome to send your observations to the soapberry scientists.
Well, on a glorious spring day at the UC Davis Arboretum's Storer Garden, we saw about 50 of these intriguing bugs. Fifty Shades of Gray (and Red). They were looking for mates on a tree trunk. Up, down, around. Repeat. Up, down, around. Well, hello, there!
The "R" word came into play: reproduction.
"The soapberry bug life cycle seems straightforward: male and female mate, the female lays eggs, the young hatch from the eggs, grow, and cast off their skin (molt) as they go through several developmental stages called instars" Carroll says. "Finally, adulthood (along with a fully developed set of wings) and reproductive maturity are achieved and the cycle begins again. However, several aspects of this cycle are more complex than they initially appear. Firstly, just because a male mates with a female, does not necessarily mean that he will father her offspring. In soapberry bugs (and many other organisms), the sperm of the male that was the last to mate with the female has precedence over the sperm deposited by those that mated with her previously. Thus, natural selection favors males with the behavior, morphology, and physiology that increase the chance that they will be the last male to mate with any given female before she lays her eggs. This phenomenon inevitably contributes to reproductive competition between males."
There you have it. No soap opera. No romance. No playing around. Just 50 Shades of Gray (and Red).
