The wildfires that raged through California, crippling and/or destroying beekeepers' homes and their livelihoods are heartbreaking. One victim, Caroline Yelle, owner of Pope Canyon Queens (PCQ), located on 8307 Quail Canyon Road, Vacaville,  lost 500 hives. The farm home of her mentor, friend and business partner, Rick Schubert--and where they headquartered the business--went up in flames. (See Bug Squad blog and Gofundme account)

UC Davis alumnus and bee expert Elizabeth Frost, a technical specialist for bees with the New South Wales Department of Primary Industries, sadly knows the fire scene well. 

Frost, a 13-year beekeeper, recently authored "24 Million Acres: Reports from Australia's Massive Fire Scar," published in the quarterly magazine, 2 Million Blossoms. The informative piece tackles the subject of Australian bushfires and it provides insight into the kind of scorched path lying ahead for California beekeepers.

 "Bees don't abscond but stay with the hives as far as I can tell from beekeeper anecdotal evidence," Frost told us this week. "Where a 'cool' burn runs quickly through the bee yard, hives generally suffer from radiant heat. Post-fire, they should should be fed supplementally if there are no natural food sources where they can be moved to, and requeened. Otherwise,  ongoing queen/productivity issues result."

At UC Davis, Frost worked with bee breeder-geneticist Susan Cobey (now at Washington State University) at the Harry H. Laidlaw Jr. Honey Bee Research Facility.  The two colleagues are closely following the California wildfire disaster. "This is devastating--it will take years to recover," Cobey said.

An integral part of what's occurring both here and Australia, the colleagues said, is climate change. "Prolonged and potentially extreme bushfire seasons in Australia due to climate change is our present reality, not our future," wrote Frost in 2 Million Blossoms.

Meanwhile, the Australian Honey Bee Industry Council is keying on rebuilding the bushfire-devastated honey bee and pollination  industry. 

Frost described the 2019-20 bush fires in 2 Million Blossoms: "24 million acres were burnt in Australia's 2019-2020 bushfire season. In Australia's biggest beekeeping state, New South Wales (NSW), the 2019-20 bush-fires burnt through 13 million acres, 7% of the state's area, including 37% of NSW National Parks and 50% of State forests. NSW Apiarists' Association President Stephen Targett noted, “NSW Bushfires have burnt over 9,809 hives and wiped out the field of over 88,094 hives and burnt just over 5 million hectares of forests. With minimal autumn prospects, a small percentage of these affected hives will be suitable for almond pollination. While the mature almond orchards in Australia don't cover anywhere near as much land as in the United States, they still require around 220,000 hives in August, when mass bloom occurs in the Southern Hemisphere." 

"This bushfire disaster was unprecedented in its impact on the Australian beekeeping industry which relies on native tall timber forests of nectar and pollen yielding trees to produce 30,000 tons of honey in a good year," Frost wrote. "Most of these species flower once every 3 to 4 years, unless soil moisture is below average for extended periods in which case some trees may not flower for up to 10 years. Australia's unique flora and dispersed bloom times means beekeepers must pay keen attention to botanical detail in order to effectively migrate to nectar flows that are not annual or even biannual. Australia lost vast swathes of vital natural sources of nutrition, species that provide car- bohydrates, proteins, amino and fatty acids, vitamins, and minerals. The bushfires destroyed prime habitat that functioned as a safe haven far from the threat of pesticides to honey bees and native pollinators alike."

Frost called attention to the Commonwealth Scientific and Industrial Research Organisation (CSIRO), a leading Australian federal government scientific agency, that has been conducting bushfire research for almost 70 years. "Bushfires are a natural part of the Australian landscape, necessary for the regeneration of many endemic plant species that evolved with the harsh climatic conditions of the world's lowest, flattest and (apart from Antarctica) driest continents," Frost pointed out.  CSIRO reports that “bushfires are the result of a combination of weather and vegetation (which acts as a fuel for the fire), together with a way for the fire to begin – most commonly due to a lightning strike and sometimes human-influences (mostly accidental such as the use of machinery which produces a spark).” 

The impact of climate change has led to longer, more intense fire seasons, Frost related, and an increase in the average number of elevated fire weather days, as measured by the Forest Fire Danger Index (FFDI). Last year saw the highest annual accumulated FFDI on record.

"Climate change doesn't cause fires directly, but has caused an increase in the occurrence of extreme fire weather and in the length of the fire season across large parts of Australia since the 1950s," Frost wrote. "In addition to 2019 being the driest year since records began in 1900, it was Australia's warmest year. In 2019 the annual mean temperature was 1.52 °C above average.”

Frost asked: "In the short term, how will the beekeeping industry evolve to cope with millions of acres of its floral resource burnt and unproductive, providing no bee forage for at least the next few years? Supplemental feeding, previously practiced sparingly in Australia, will have to become the norm for the country if beekeepers hope to bring colonies up to required colony strength as agreed in their almond pollination contracts."

Sadly, it's a long singed recovery as well for the California beekeepers victimized by the wildfires.  (To offer financial support for Caroline Yelle, owner of Pope Canyon Queens, access the Gofundme account.)   

It's heartbreaking. Beyond heartbreaking.

Caroline Yelle, 28, owner of Pope Canyon Queens (PCQ) at 8307 Quail Canyon Road Quail Canyon Road, Vacaville, lost her business when the lightning-sparked Hennessey Fire, part of the LNU Lightning Complex Fire, swept through rural Vacaville on Aug. 19 from Napa County. 

The raging wall of flame "destroyed everything."

She has nothing left but hope. 

Pope Valley Queens is one of the nation's few women-owned queen bee breeder businesses. Yelle breeds bees for "a better tomorrow" and now "tomorrow" and "better" are almost singed from her vocabulary.

She lost 500 hives.

Her mentor, best friend and business partner Rick Schubert (who recently sold his business, Bee Happy Apiary, Vacaville), lost everything in the Hennessey Fire, including his newly remodeled home at 8307 Quail Canyon Road--and where the PCQ office was.

"I bought the company in 2017 from my mentor,"  said Yelle, who began working there in 2012. "This year, 2020 is my seventh year in producing queens."

"I was studying to be a lawyer in Canada," she related. "After I got my degree, I decided to move here and left everything behind to follow my dream with the bees and helping them." 

Veteran beekeeper Schubert, who has kept bees for some four decades, is well known in the bee industry and agricultural world. He helped her settle in California and build the company, offering contacts and expertise. "Rick had just remodeled his house and that (the fire) happened," Yelle said.  "He lost everything." Schubert's only surviving bees are the 100 hives he keeps in Dixon.

"Basically after selling Bee Happy, he invested in my company, Pope Canyon Queens," she said. "We lost everything together on different levels."

We Lost the Farm
"We (Rick Schubert and her) lost the farm, the house, the garage, the bees," Yelle said. "We have the majority of our bees on another property up in Pope Canyon Valley that also burned. We lost around 500 hives or $100,000 in livestock--minimum--that is not covered...and another $100,000 of benefits out of these hives. We are back to ground zero."

"I've been working for seven years to get where I was," she said. "I moved here (from Canada) and left everything behind to reach that goal, and have been working on selecting better genes to help to save the bees for feeding the nation. The Hennessey Fire destroyed EVERYTHING we owned."

Yelle mainly breeds Carniolans, Apis mellifera carnica, a subspecies of the western honey bee and "a hybrid that we selected in Canada and we reproduce here in California for stronger genes." 

"The Canadian beekeeping industry needs tons of early queens in the spring," she said. "We decided seven years ago to bring our northern and robust queen bee genetics, selected over more than 20 years, to produce here." She has an isolated mating station in Napa Valley (Pope Canyon Valley).

"Our goal was not to compete with the big queen guys that already export massive amount of queens but try to increase the level of quality standard into the queen importation issue in Canada and the United States," Yelle said. Over the years, they reached their goal of quality standard.

"However," she said, "we are still working to improve our genetics and to expand our production year after year."

Bee Source published this about the business in 2017: "Pope Canyon Queens LLC (PCQ) want and choose to be at the forefront breeding genetics to help bee populations to better defend themselves against mites, viruses, bacteria, pollination and commercial beekeeping stresses, pollution, depleting floral diversity and ever changing ecosystems. By confronting these challenges head on, PCQ will come to represent a turning point in the strengthening of bee populations. Its 'raison d'etre' is rooted in the urgency of grafting solid apicultural know-how onto strong genetics to meet today's challenge of breeding a better tomorrow."

'It Will Take Years to Recover'
Bee breeder-geneticist Susan Cobey of Washington State University, a former manager of the Harry H. Laidlaw Jr. Honey Bee Research Facility at UC Davis, called the fire "devastating." She knows of several beekeepers, including the Yelle-Schubert team, who lost everything in the tragic fire. "It will take years to recover." 

"The story needs to be told," said Cobey, who breeds Carniolans. "These beekeepers work so hard. The impact of California agriculture will be huge, our breadbasket. It's about climate change, too." 

"Sue is part of our family group," Yelle said. "We had programs on breeding stock and selection of genes." Yelle also works closely with bee breeder-geneticist Kim Fondrk, of the Laidlaw facility. For decades, Fondrk managed research bee colonies at the Laidlaw facility for Robert Page Jr., former chair of the UC Davis Department of Entomology who recently retired as provost at Arizona State University. Together Page and Fondrk wrote landmark research articles. 

"Kim worked with and for us for us over the past years," Yelle recalled.  Schubert also worked with bee scientist Norm Gary, emeritus professor, UC Davis Department of Entomology and Nematology, also known as an author, bee wrangler and musician. "We provided bees for Norm's research," Yelle related. Schubert provided bees for Gary's bee wrangling projects.

Now Yelle, who is accustomed to helping others,  needs others' help. 

"We need help with the bees that burned to be able to keep breeding them and bring back our livestock for next year pollination and to keep feeding the nation," Yelle said.

'Help Us Rebuild to Save the Bees'
Yelle has set up a gofundme account, "Help Us Rebuild to Save the Bees," at https://gf.me/u/ys2vtw

"The help and support we are getting is really heartwarming," Yelle wrote on on the gofundme support page. "Thank you for the messages, the calls, the shares, the donations, the thoughts and everything. I see every single of your names and have such strong emotions about how much people care about us, about the bees and about their community. Some really good news so far: a bee company contacted us to help us rebuild the materials for lowest cost possible, my California family offered me a part of their barn for me to have a start before rebuilding."

Yelle is grateful that "someone saved a bee yard that was literally in the middle of one of the worst part of the fire," and she and a neighbor helped saved a mini farm from the fire.  "Community is strong."

Strong...and from heartbreaking to heartwarming...

It's good to see Washington State University Extension's newly published, updated fact sheet on the Asian giant hornet, Vespa mandarinia. You can view or download it here for free.

Remember the massive media frenzy earlier this year when "the murder hornet" became a household word? The media labeled it that, but let's call it AGH. It's a hornet, not some weaponized insect with super powers that belongs in a B-rated movie seen at a Saturday matinee. Drop the drink! Hold the popcorn!

The peer-reviewed publication is the work of two former UC Davis entomologists now with WSU: honey bee geneticist-researcher Susan Cobey, research associate, Department of Entomology, and Timothy Lawrence, associate professor and Island County Extension director (they are a husband-wife team), along with Michael Jensen, associate professor and Pend Oreille County Extension director.

The first four paragraphs zero in on what this is all about: 

"The Asian giant hornet (AGH) or Japanese giant hornet, Vespa mandarinia, recently found in British Columbia, Canada, (B. C. Ministry of Agriculture 2019) and in Washington State (McGann 2019), poses a significant threat to European honey bee (EHB), Apis mellifera, colonies and is a public health issue. The AGH is the world's largest species of hornet (Figure 1; Ono et al. 2003), native to temperate and tropical low mountains and forests of eastern Asia (Matsuura 1991). It appears the hornet is well adapted to conditions in the Pacific Northwest.

"If this hornet becomes established, it will have a severe and damaging impact on the honey bee population, the beekeeping industry, the environment, public health, and the economy. It is critical that we identify, trap, and attempt to eliminate this new pest before it becomes established and widespread. Attempts to contain the spread and eradication of this invasive insect will be most effective by trapping queens during early spring before their nests become established. Another strategy is to locate and destroy nests prior to development of virgin queens and drones in the late summer and fall.

"It is critical that surveying and trapping occur before the fall reproductive and dispersal phase of the hornet. Beekeepers in the field are a crucial line of defense in locating, identifying, and trapping the hornets. Yet, everyone should be on the lookout and report any sightings to local authorities and the Washington State Department of Agriculture.

"Here, we will cover how the AGH will impact the honey bee, give the reader a better understanding of the hornet, outline precautions to take, and first aid if attacked by the hornet."

The fact sheet provides crucial information, including what the public and beekeepers need to know, how to trap the hornets, where to report sightings, and information about the life cycle, the stinger,  avoidance, and first aid. It details the public health issue and defines "What is a hornet?" 

We've heard folks argue that AGH is a "hornet, not a wasp."  Noted hymenopterist Lynn Kimsey, director of the Bohart Museum of Entomology and professor of entomology at UC Davis, points out that hornets ARE wasps.

WSU Extension defines a hornet this way:

"A hornet is simply a large wasp. Generally, wasps of the class or genus known as Vespa are considered hornets. Interestingly, there are no true hornets (Vespa) native to North America. The European hornet (Vespa crabro) is well established in much of the eastern half of the United States. The European hornet is not a major threat to honey bees."

"Hornets are part of a large order of insects known as Hymenoptera that include bees, wasps, ants, and sawflies. Worldwide, there are more than 115,000 species belonging to the order Hymenoptera (Hunt and Toth 2017). Most of this group of insects are beneficial for pollination and pest control. There are two types of hornets, solitary and social (Lee et al. 2016). Solitary hornets hunt various insects and spiders. Their 'stinger' is primarily used to paralyze their prey. They often lay an egg on the immobilized victim, and when the egg hatches, the larvae consume the still-living host. Solitary wasps generally do not sting humans and usually are not aggressive unless provoked."

"Social wasps, on the other hand, do use their stingers to defend their nests and can be very aggressive and will readily sting. The most common social wasp in the United States is the yellowjacket. The four most common yellowjacket species in Washington are the western yellowjacket (Paravespula pensylvanica), the common yellowjacket (Paravespula vulgaris), the aerial yellowjacket (Dolichovespula arenaria), and the German yellowjacket (Paravespula germanica) (Berry and Mooney 1998; Landolt and Antonelli 2003)."

"The recently introduced Asian giant hornet (AGH) is also a social wasp. When foraging for food in spring, the AGH ;is not highly aggressive—unless its nest is disturbed. Late summer and fall, with the high demand for protein, they become very aggressive when attacking or occupying a honey bee colony."

AGH appeared in the news last month when the Washington State Department of Agriculture announced it had trapped aVespa mandarinia near Birch Bay in Whatcom County. It was trapped July 14 and identified during processing on July 29. "This was the first hornet to be detected in a trap, rather than found in the environment as the state's five previous confirmed sightings were," according to the news release.

"Because the number of Asian giant hornet workers increases as a colony develops, residents should be most likely to see an Asian giant hornet in August and September," the news release related. "If you think you have seen one, report it at agr.wa.gov/hornets. Provide as much detail as you can about what you saw and where. Also, include a photo if you can safely obtain one, and if you come across a dead specimen keep it for potential testing. You can visit WSDA's website at agr.wa.gov/hornets to learn more about Asian giant hornets. You can also submit questions the WSDA Pest Program at hornets@agr.wa.gov or 1-800-443-6684." 

At least we never saw a 64-point bold, all-capped, World War II-sized newspaper headline that screamed "MURDER HORNET TRAPPED!"  

But some of the misidentifications of Vespa mandarinia flowing in are incredible. Check out Stephane de Greef's Facebook page on "Is This a Murder Hornet?" The latest one spotlighted is a...wait for it...beetle.

The sensationalism. fear-mongering and general panic surrounding those Asian giant hornets, aka "murder hornets," detected last year in British Columbia and Washington state, are enough to curdle both the blood and the brain.

First there were the Africanized honey bees, which sensationalists called "the killer bees."

Don't even mention "assassin flies" or "bullet ants" or "deathwatch beetles."

Now there are the Asian giant hornets (AGH), Vespa mandarinia, which sensationalists have dubbed "murder hornets." 

"It's ridiculous to call them murder hornets,” says noted UC Davis wasp expert and researcher Lynn Kimsey, director of the Bohart Museum of Entomology and professor of entomology, UC Davis Department of Entomology and Nematology.

“It's no more likely to sting and kill a human than a honey bee,” said Kimsey, a two-term past president of the International Society of Hymenopterists, an organization that studies bees, wasps, ants, and sawflies.

“Actually it's less likely, as honey bee venom packs quite a punch and it is exclusively designed to defend against vertebrates,” she said.

“The colony everyone is hyperventilating over was actually found on Vancouver Island, British Columbia, last September when it was destroyed and then a single, dead hornet was found in December in Blaine, Wash.,” Kimsey said. “There is no evidence that there are any more hornets in the vicinity of Vancouver or anywhere else on the West Coast.”

A colony of the Asian giant hornets was found and destroyed Sept. 18, 2019 in Nanaimo, Vancouver Island, and the single dead hornet was found Dec. 8, 2019 in Blaine.

These were the first detections of this species in North America, but there may be more, according to the Washington State Department of Agriculture (WSDA). Beekeepers have reported “observations” (which may or may not be the same species) dating back to October 2019, according to officials in Washington State University's  Department of Entomology and Cooperative Extension. They and the beekeeping organizations want to know what's out there and they want folks to keep a lookout for them. 

Said Kimsey: “A decade or more ago there was a colony of another species, Vespa asiatica, reported near the Port of Long Beach but nothing ever came of that either. A European species, Vespa crabro, was introduced into the East Coast perhaps a century ago and it is now fully established in the southeastern U.S.”

Kimsey points out that insects often come in cargo boxes from Asia to U.S. ports, establish colonies, and expand their range.

A soon-to-be-published article in the Entomological Society of America's journal, Insect Systematics and Diversity, promises to shed more light on the genus and the history of introductions in the United States.Kimsey and colleagues Allanmith-Pardo of the USDA and James Carpenter of the America Museum of History, New York, co-authored the review article.

In the abstract, the authors define Vespa as social wasps that are “primarily predators of other insects, and some species are know to attack and feed on honey bees, Apis mellifera, which makes them a serious threat to apiculture.”

“Vespa nests can be physically large, with over 1,000 workers, but usually with hundreds of workers,” they wrote. “Nests can be aerial, attached to tree branches or in shrubs, in crevices, under eaves or underground depending on the species. Depending on the latitude, nests can be either annual, started by a new queen every spring, or perennial, where young queens take over from old ones. Colonies in warm tropical climates tend to be perennial.”

Washington State University (WSU) Extension recently published an AGH fact sheet, the work of three scientists: Susan Cobey, bee breeder-geneticist and husband Timothy Lawrence, county director of Island County Extension (both formerly of UC Davis), and Mike Jensen, county director of Pend Oreille. (See https://bit.ly/2SA3TxS)

Yes, hornets are huge. They measure about two inches long, and the queens can fly up to 20 miles per day, said Cobey, who examined specimens in Japan last December and shipped some of them to WSU.

The WSU scientists wrote that AGH “is the world's largest species of hornet, native to temperate and tropical Eastern Asia low mountains and forests. The hornet is well adapted to conditions in the Pacific Northwest.”

“The primary purpose of venom is defense against predators by inflicting pain and damage,” they wrote. ”Vespa mandarinia is one of the two most venomous known insects in the world.. The amount of venom each wasp delivers (4.1 μl/ wasp) has designated V. mandarinia as the most venomous insect. In comparison, the honey bee has about 0.6μl/bee. When foraging for food in spring, the AGH is not highly defensive – unless its nest is disturbed. Late summer and fall, with the high demand for protein, they become very aggressive when attacking or occupying a honey bee colony.”

“It is critical that we identify, trap, and attempt to eliminate this new pest before it becomes established and widespread,” they wrote. “Attempts to contain the spread and eradication of this invasive insect will be most effective in trapping queens during early spring before their nests become established. Finding the nests can be a bit of a challenge. Their nests are typically in the ground though they can also be found under overhangs and within wall voids. The AGH is a strong flier and often will fly up and away and have an extensive flight range. Thus tracking can be difficult.”

They advise residents to “proceed with extreme caution and contact WSDA immediately. Do not try to exterminate the nest yourself.”

Entomologists call them Asian giant hornets or Vespa mandarinia.

Social media?

Murder hornets. 

Could we just go back to calling them Asian giant hornets or AGH or Vespa mandarina?

Please?
