Scientists at the UC Davis Bohart Museum of Entomology will help you do just that.
They've scheduled an open house on “Arthropod Husbandry: Raising Insects for Research and Fun” from 1 to 4 p.m., Saturday, Nov. 16 in Room 1124 of the Academic Surge Building on Crocker Lane. It's free and family friendly.
"We will have a number of people who are expert at raising insects, both for research and for fun," said Tabatha Yang, Bohart Museum education and outreach coordinator. UC Davis student Andrew Goffinet, a former UC Davis Bio Boot Camper, will be on hand to talk about rearing butterflies and moths. UC Davis entomology alumnus Lohit Garikipati will discuss praying mantids.
Another entomology alumnus Nicole Tam, will talk about rearing insects in the Geoffrey Attardo lab as part of research projects. Doctoral student and Bohart associate Zaid Khouri's topic is how to rear tarantulas and millipedes for fun.
"We also will be discussing Madagascar hissing cockroaches (hissers) as good options for 'starter pets' for kids, and some of the problems with stick insects (walking sticks)," Yang said. Visitors are invited to hold the hissers and stick insects and photograph them.
At 3 p.m., silkworm moth expert İsmail Şeker, a Turkish medical doctor who wrote a book about silkworm moths and the cottage silk industry in his home town, will show his newly produced video about the silkworm moth life cycle. Seker, also a talented videographer and a photographer, will answer questions following his 13-minute video presentation.
"This will be a fun open house for anyone considering a pet with an exoskeleton," Yang said."It will be good for educators to learn about classroom 'pets,' including those who do work with silk moths for life cycle lesson plans."
"Also, to kick off the holiday season we will have the unique wire jewelry by former entomology major Ann Kao, so people should be prepared to shop for some unique insect-inspired jewelry."
A family craft activity is also planned. This is the last open house of the year. The next open house will be on Jan. 18 when UC Davis graduate students from many different fields "will be talking/displaying about their cutting edge research with insects," Yang said.
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 and tarantulas. The museum's gift shop, open year around, is stocked with T-shirts, sweatshirts, books, jewelry, posters, insect-collecting equipment and insect-themed candy.
Director of the museum is Lynn Kimsey, professor of entomology at UC Davis. The staff includes Steve Heydon, senior museum scientist; Tabatha Yang, education and outreach coordinator; and Jeff Smith, who curates the Lepidoptera (butterflies and moths) section.

The jewel beetle engages in host shifting. It's been detected in two non-ash species: the white fringetree and an olive tree species in research led by Don Cipollini, professor of biology in the Department of Biological Sciences, Wright State University, Dayton, Ohio.
Cipollini will share his expertise on the emerald ash borer, Agrilus planipennis, when he addresses a UC Davis Department of Entomology and Nematology seminar on Wednesday, Nov. 13.
His hour-long seminar, titled "The Potential for Host Switching via Ecological Fitting in the Emerald Ash Borer-Host Plant System," starts at 4:10 p.m. in 122 Briggs Hall, off Kleiber Hall Drive.
"The traits used by phytophagous insects to find and utilize their ancestral hosts can lead to host range expansions, generally to closely related hosts that share visual and chemical features with ancestral hosts," Cipollini says in his abstract. "Host range expansions often result from ecological fitting, which is the process whereby organisms colonize and persist in novel environments, use novel resources, or form novel associations with other species because of the suites of traits that they carry at the time they encounter the novel environment."
Cipollini will discuss "the potential and constraints on host switching via ecological fitting."
"Once thought of as an ash (Fraxinus spp.) tree specialist, recent studies have revealed a broader potential host range than was expected for this insect," Cipollini says. "I will discuss the demonstrated host-use capabilities of this beetle, as well as the potential for and barriers to the adoption of additional hosts by this beetle."
"We place our observations in the context of biochemical mechanisms that mediate the interactions of these beetles with their host plants, and discuss whether evolutionary host shifts are a possible outcome of the interaction of this insect with novel hosts."
In research published in the Journal of Economic Entomology in May 2017, lead author Cipollini and fellow researchers at Wright State University detailed how the emerald ash borer can develop from larvae to adulthood on a species of olive tree. They also published a piece in entomologytoday.org.
The emerald ash borer lays its eggs in bark crevices, primarily ash trees, and its larvae feed beneath the bark. In the United States, its core population centers around Michigan and surrounding states.
Manuka honey is produced in New Zealand and Australia, but New Zealand claims the manuka honey trademark. Australia says that's not fair. They want to use it, too.
Manuka is to honey what Château Cheval Blanc 1947 is to wine connoisseurs. Buy a bottle of that wine and you'll fork over $304,375. Buy an eight-ounce jar of manuka honey and you'll lighten your wallet by $1790.
Bees make manuka honey from Leptospermum scoparium, also known as "The New Zealand tea tree" or more accurately, "bush." The honey prized for its health benefits, including its antibacterial and antifungal properties and anti-inflammation qualities.
According to webmd.com, "The major antibacterial component in manuka honey is methylglyoxal (MG). MG is a compound found in most types of honey, but usually only in small quantities. In manuka honey, MG comes from the conversion of another compound, dihydroxyacetone, that is found in high concentration in the nectar of manuka flowers."
"The higher the concentration of MG, the stronger the antibiotic effect. Honey producers have a scale for rating the potency of manuka honey. The rating is called UMF, which stands for Unique Manuka Factor. The UMF rating reflects the concentration of MG. To be considered potent enough to be therapeutic, manuka honey needs a minimum rating of 10 UMF. Honey at or above that level is marketed as UMF Manuka Honey or Active Manuka Honey.
reports that New Zealand's honey producers have long argued that it's the only country that can produce true manuka honey, because it's the only place where the manuka bush (Leptospermum scoparium) is found. Australian manuka, they argue, comes from other different-but-related species. (The New Zealanders have previously suggested that the Australian version should be called tea tree honey.)recently wrote in Wine and Food: "The New York Times
Manuka honey? Tea tree honey?
Well, we just think of the bees and that beautiful plant.
For five years, we grew a Leptospermum scoparium keatleyi, the tallest and rangiest variety of the Leptospermum scopariums. It bears our family name, Keatley; New Zealand sea skipper/horticulturist Capt. Edward John "Ted" Keatley (1875-1962) discovered it and named the variety "keatleyi."
Factoids: According to the Maritime Museum in Wellington, New Zealand, Capt. Keatley once commanded 28 of the Northern Steam Ship Company's vessels. He also was considered an authority on the flora of the Auckland province. In June 1961, the Royal Horticulture Society awarded Capt. Keatley the "Award of Merit" for his discovery of the keatleyi, or "royal pink manuka."Sadly our "Keatley" plant didn't make it past five years. But generations of honey bees nectared on the blossoms while the plant thrived in our yard.
The UC Davis Computer Science Club.
And, now the three-year collaborative project is a reality.
Using this innovative app, strawberry growers can better combat such pests as two-spotted spider mites, lygus bugs and leafrollers--and save money.
Hats off to the ag expertise of Nansen and the app development skills of three student computer scientists.
“Many variables are known to affect the actual spray coverage in crop fields,” said Nansen, an associate professor in the UC Davis Department of Entomology and Nematology said. “These include tractor speed, spray nozzles, spray volume, boom height, adjuvants, and weather conditions. But which ones are the most important ones? And are there possible interactions among some of these variables?”
Through Smart Spray, an app designed for both iOS and Android phones, growers can optimize and perform quality control of pesticide spray applications in their strawberry fields, Nansen said.
Computer science major Krishna Chennapragada, now an alumnus, launched the programming and initial design, tallying some 500 hours before his graduation. Today's team, in addition to Nansen, is comprised of recruits Gabriel Del Villar, a 2019 computer science graduate, and Alexander Recalde, a senior majoring in computer science. Together they have amassed nearly 400 hours on the project.
The Smart Spray app, they said, allows a user to predict spray coverage under different operational scenarios, including type of nozzles, spray volume, and tractor speed, as well as weather data, such as temperature, relative humidity and wind. A key part of the process: the user places a water-sensitive card in the field prior to a spray application, photographs it, and uploads it into the app.
“If you're a grower, you might expect that when you go out to spray, that the more that comes out of nozzle, the better coverage you'll get,” Nansen said. “But, for example, if the wind is too strong, the relative humanity is too low, the pressure is too high, or you're going too fast--even when you're spraying large volumes--you can get very poor coverage and it's costly. Excessive spray can also reach other fields or nearby urban developments due to so-called “spray drift”.”
“Typically, a grower will spray 100 to 150 gallons per acre when he or she sprays,” Nansen explained. The water-sensitive card is yellow, but it codes blue when it interacts with moisture. “These cards have been around a long time,” he said. “They cost about $1 a card, not cheap. But it's inexpensive when you're spending thousands of dollars to control the pests. And the pesticide companies can pay for the cards.”
“Using this prediction, you can give it a name, say Field 6, and access it from the database,” Nansen said. “It's about quality control. It's a tool to predict and do quality control. It empowers the grower and also the sprayer to do a better job. For example, if the conditions are bad and the app shows the spraying will be only 20 percent effective, you shouldn't be spraying.”
Recalde said the user can also choose metric or imperial, as well as add the Global Positioning System or GPS.
“The Smart Spray is not just insecticides--it's fungicides, herbicides, and whatever you want to spray,” Nansen noted. “This app was developed for strawberries; if it were used for soybeans, onions and cabbage, it would still be useful but the accuracy would be off.” Pending apps: almond, pistachio and tomato.
The computer scientists enjoy working on the project. Recalde attended a Central Coast sprayers' meeting to talk about the app. “I heard ‘Oh, wow, you look so young!' he remembered. “Then we told them about this useful tool, different ways that technology can be applied to agriculture. They were really interested in how technology can improve what they're doing.”
Del Villar, whose computer interests also include teaching youth how to code, said he eagerly looks forward to making the Smart Spray app even better and more useful. Fluent in Spanish, as well as English, he plans to translate the app into Spanish. Other language translations are also in the works.
Now the team is seeking feedback to improve the app. “We're hoping growers will embrace it,” Nansen said, “and help us find ways to improve it.”
One feedback from Eric Flora, global field development and manager of Crop Enhancement, Inc., Paso Robles: “I think Smart Spray is a very helpful tool for growers and advisers as a guide to select spray tips, spray volumes, tractor speed, and other important factors to maximize sprayer coverage. Using spray cards is the best and simplest way to know, if you are penetrating everywhere in the canopy your pest target is a problem--placing cards where the specific pests attack the host gives the best information.”
State, federal and industry grants, including the California Strawberry Commission and the Floriculture and Nursery Research Initiative (FNRI) of the U.S. Department of Agriculture's Agricultural Research Service, help fund the project.
California grows about 88 percent of the nation's strawberries on approximately 34,000 acres along the California coast, according to the Strawberry Commission. Strawberries are available year-around in California.
Statewide, fresh strawberry production averages 50,000 pounds per acre each season. The approximately 300 strawberry growers hail from five distinct areas of California: Watsonville/Salinas, Santa Maria, Oxnard, Orange County/San Diego, and the Central Valley. They include multi-generation farming families growing both organic and conventional strawberries.
