Ever tasted a cricket? A mealworm? An earthworm?
You can if you attend the Bohart Museum of Entomology open house themed "Gobble, Gobble, Munch, Munch, Crunch: Entomophagy,” to be held from 1 to 4 p.m., Saturday, Sept. 21 in Room 1124 of the Academic Surge Building on Crocker Lane.
Open to the public, it's free and family friendly, said Lynn Kimsey, director of the Bohart Museum and professor of entomology at UC Davis.
“The theme is entomophagy and we have some samples from various companies coming our way,” said Tabatha Yang, education and outreach coordinator. Companies providing samples include Hotlix, Exo and Chirps Chips.
Said Kimsey: "Many insects are quite edible and if you try them you might find that crickets are the new shrimp. Personally, I like flavored mealworms."
"Just think of insects as terrestrial shrimp or crab," said senior museum scientist Steve Heydon.
The event will include learning about entomophagy, sampling insect-based foods, button-making (“I ate a bug at the Bohart”), viewing the collection, and handling insects from the petting zoo, which includes Madagascar hissing cockroaches, stick insects and tarantulas. Yang and Bohart associate Emma Cluff recently completed an online training for food handling, as required by UC Davis.
In preparation for the event, Bohart Museum volunteer Iris Bright, a second-year biology major at Sacramento City College, sampled crickets, mealworms and earthworms last week.
Bright liked them all. “They're good,” she said, as she tasted red, green and blue earthworms. She described them as having "a sweet and sour taste." The mealworms? “Somewhat cheesy.”
“The crickets are crunchy," she said, adding "I've had them before.”
Eighty percent of the world population, including those living in Central and South America, Africa, Asia, Australia, and New Zealand, consume insects as a high protein source. Some 1700 species of insects are edible.
The Food and Agriculture Organization of the United Nations (FAO) has registered some 1,900 edible insect species and estimates that there were, in 2005, some two billion insect consumers worldwide. FAO suggests eating insects as a possible solution to environmental degradation caused by livestock production. Insects and arachnids eaten globally include crickets, cicadas, grasshoppers, ants, various beetle grubs (such as mealworms, the larvae of the darkling beetle, various species of caterpillars (such as bamboo worms, Mopani worms, silkworms and waxworms), scorpions and tarantulas, according to Wikipedia.
Spencer Michels in a PBS News Hour report in May 2017, commented: “But the big advantage of eating insects is that they are generally healthier than meat. A six-ounce serving of crickets has 60 percent less saturated fat and twice as much vitamin B-12 than the same amount of ground beef. ..Bugs also don't spread disease to humans the way cows — think mad cow disease– or pigs can.”
“I do realize that insects do have a bad rap,” California Academy of Sciences entomologist Brian Fisher recently said. “Most people see insects are pests or as dangerous. But it's just the opposite. Insects are less dangerous and less of a problem for humans in terms of disease."
“We do have concerns about disease jumping from animals like pigs and cows to humans,” Fisher said. “But there are no worries about a disease jumping from an insect to humans. The more evolutionary distant we are from our food source, the less danger there is. … There is almost zero chance that any disease that affects an insect could actually impact a human after it's cooked.”
Celebrity bug chef David George Gordon, author of the “Eat-a-Bug” cookbook, extolled the virtues of the “bugs as food” movement when he addressed a UC Davis audience in 2014 at the Robert Mondavi Institute for Wine and Food Science. Insects are an environmentally friendly source of protein, he said, and bug farming reduces greenhouse gas emissions and is exponentially more water-efficient than farming for beef, chicken, or pigs.
The Bohart Museum houses a global collection of nearly eight million specimens. It is also the home of the seventh largest insect collection in North America, and the California Insect Survey, a storehouse of the insect biodiversity. Noted entomologist Richard M. Bohart (1913-2007) founded the museum. It maintains a live "petting zoo," featuring Madagascar hissing cockroaches, walking sticks or stick insects, tarantulas, and praying mantids. The museum's gift shop, open year around, includes T-shirts, sweatshirts, books, jewelry, posters, insect-collecting equipment and insect-themed candy.
The museum is open to the public Mondays through Thursdays from 9 a.m. to noon and 1 to 5 p.m., except on holidays. More information on the Bohart Museum is available on the website at http://bohart.ucdavis.edu or by contacting (530) 752-0493 or firstname.lastname@example.org.

"Beekeeping and Management" will be part of the two-day UC Davis School of Veterinary Medicine's 2019 winter conference presented by its Center for Continuing Education in February 2019.
The conference, covering several vet med topics or tracks, is set for Saturday and Sunday, Feb. 9-10. The beekeeping portion is on Sunday morning, Feb. 10.
California Extension apiculturist Elina Lastro Niño, based in the UC Davis Department of Entomology and Nematology, will present the three seminars dealing with "Beekeeping and Management" in the Gladys Valley Hall, UC Davis School of Veterinary Medicine.
The bee schedule:
- 8:10 to 9 a.m.: "Honey Bee Biology and Apiculture Overview"
- 9:10 to 10 a.m.: "Common Issues in American Apiaries"
- 10:30 to 11:20 a.m.: "Honey Bee Bacterial Diseases and Antiobiotic Use"
Special pricing for those interested in attending only the "beekeeping track" is available, announced Saundra Wais, program manager for the Center for Continuing Professional Education. The onsite fee for this section is $45. A live webinar option is available for $40 for those who cannot be on campus, she said.
Several other tracks are scheduled, including Doctor of Veterinary Medicine (DVM), Veterinary Technician (Vet Tech), Feline Dentistry Lab, and Food Animal Reproduction and Medicine (FARM) Club. Some 20 speakers are planned.
The two-year research, led by Ola Lundin, a former postdoctoral fellow in the Neal Williams lab, UC Davis Department of Entomology and Nematology and published in the Journal of Applied Ecology, details what plants proved most attractive to honey bees, wild bees and other pollinators, as well as what drew such natural enemies as predators and parasitic wasps.
The research, “Identifying Native Plants for Coordinated Habitat Management of Arthropod Pollinators, Herbivores and Natural Enemies,” is co-authored by Williams, professor of entomology and a Chancellor's Fellow at UC Davis; and project specialist Kimiora Ward of the Williams lab.
“I hope this study can inform selection of plants that support pollinators and natural enemies without enhancing potential pests,” said Lundin, first-author of the paper and now a postdoctoral fellow in the Department of Ecology, Swedish University of Agricultural Sciences, Uppsala.
“Planting wildflowers is a key strategy promoted nationally to support wild and managed bees,” said Williams. “Successful adoption of these plantings in agricultural landscapes will require that they not only support pollinators but that they also avoid supporting too many pests. Plant selection going forward will need to balance multiple goals of pollinators pest management and other functions. This research is a first step on the path to identifying plants that will meet these goals."
The three scientists, who conceived the ideas and developed the methodology for the research project, established 43 plant species in a garden experiment on the grounds of the Harry H. Laidlaw Jr. Honey Bee Research Facility at UC Davis. They selected plant species that were drought-tolerant; native to California (except for buckwheat, Fagopyrum esculentum, known to attract natural enemies and widely used in conservation biological control); and, as a group, covered a range of flowering periods throughout the season.
“For early season bloom, Great Valley phacelia (Phacelia ciliata) was a real winner in terms of being attractive for both wild bees and honey bees,” Lundin said. “Elegant Clarkia (Clarkia unguiculata) flowers in late spring and was the clearly most attractive plant for honey bees across the dataset. The related Fort Miller Clarkia (C. williamsonii) was also quite attractive for honey bees and had the added benefit that a lot of minute pirate bugs visited the flowers.”
Lundin said that common yarrow (Achillea millefolium) “attracted “attracted the highest numbers of parasitic wasps but also many herbivores, including Lygus bugs.”
“In general a lot of parasitic wasps were found on Asteraceae species (the daisy family) and this was a somewhat surprising result considering that they have narrow corollas, and for parasitic wasps relatively deep corollas that can restrict their direct access to nectar. Under the very dry conditions in late summer, Great Valley gumplant (Grindelia camporum) and Vinegarweed (Trichostema lanceolatum) both performed well and attracted high numbers of wild bees.”
The team found that across plant species, herbivore, predator and parasitic wasp abundances were “positively correlated,” and “honey bee abundance correlated negatively to herbivore abundance.”
The take-home message is that “if you're a gardener or other type of land manager, what you'd likely prefer would be a mix of some of the most promising plant species taking into account their individual attractiveness for these arthropod groups, plus several more factors including costs for seed when planting larger areas,” Lundin said.
“Plant choice can also depend on how you weigh the importance of each arthropod group and whether you are interested in spring, summer or season-long bloom,” Lundin added. Those are some of the questions that the Williams lab plans to explore in future projects.
Williams praised the “uniquely capable team that came together.”
“Ola is an emerging leader in considering integrated management of pests and pollinators and Kimiora is a known expert in developing regionally-relevant plant materials to support pollinators,” Williams said. “They and some talented UC Davis undergraduates--notably Katherine Borchardt and Anna Britzman--compiled a tremendously useful study.”
The overall aim of the study “was to identify California native plants, and more generally plant traits, suitable for coordinated habitat management of arthropod pollinators, herbivores and natural enemies and promote integrated ecosystem services in agricultural landscapes,” the researchers wrote.
More specifically, they asked:
- Which native plants among our candidate set attract the highest abundances of wild bees, honeybees, herbivores, predators, and parasitic wasps,
- If the total abundances of arthropods within these functional groups across plant speacies are related to the peak flowering week, floral area, or flower type of the focal plant species, and
- If the total abundances of arthropods within these functional groups are correlated to each other across plant species.
“A first critical step for design and implementation of multifunctional plantings that promote beneficial arthropods while controlling insect pests is to identify suitable plant species to use,” the authors wrote in their abstract. “We aimed to identify California native plants and, more generally, plant traits suitable for the coordinated management of pollinators (wild bees and honey bees), insect herbivores and arthropod natural enemies (predators and parasitic wasps).”
At the time, the Laidlaw grounds included nearly 50 bee colonies: some 20 to 40 honey bee colonies, and eight managed research colonies of the yellow-faced bumble bee, Bombus vosnesenkii.
The project received funding from the USDA Resources Conservation Service, USDA Agricultural Marketing Service, USDA National Institute of Food and Agriculture and a Swedish foundation for scientific research, the Carl Tryggers Stiftelse for Vetenskaplig Forskning.
