Advanced Beek Meeting: October Recap

Adv Beek Mtg 1
The new Advanced Beekeeper meetings began at HoneyLove on October 27. Held on the last Sunday of each month at 11am at the HoneyLove office, these meetings will fill the gap left by the Backwards Beekeepers and will help advance the learning of the L.A. treatment-free community.

Each meeting will have a member-speaker teaching us all something new as well as a general open Q&A and mentorship opportunities. Beekeepers of all levels are welcome to attend; HoneyLove also has more introductory-level beekeeper meetings on the 2nd Saturday of each month. Attendees are encouraged to join HoneyLove.org for extra benefits and the tax-deductible donation.

The October speaker was Josip Benko, a second-generation beekeeper with over 30 years of experience. Josip is from the former Czechoslovakia and shares the philosophy of observing the bees because they’ll show you what they need. He is also big on experimentation and customizing his hive boxes.

Josip brought several hive box samples; these are reduced for education purposes. He now uses 7 or 9 frame boxes because his observation is that bees don’t like even numbers.

Bees Buzz Each Other, but Not the Way You Think

Electric bees? Honey bees may use electrical fields that accumulate on their bodies when they fly or move about to communicate with each other within the hive, a new study suggests.

The electric fields that build up on honey bees as they fly, flutter their wings, or rub body parts together may allow the insects to talk to each other, a new study suggests. Tests show that the electric fields, which can be quite strong, deflect the bees’ antennae, which, in turn, provide signals to the brain through specialized organs at their bases.

Scientists have long known that flying insects gain an electrical charge when they buzz around. That charge, typically positive, accumulates as the wings zip through the air—much as electrical charge accumulates on a person shuffling across a carpet. And because an insect’s exoskeleton has a waxy surface that acts as an electrical insulator, that charge isn’t easily dissipated, even when the insect lands on objects, says Randolf Menzel, a neurobiologist at the Free University of Berlin in Germany.

Although researchers have suspected for decades that such electrical fields aid pollination by helping the tiny grains stick to insects visiting a flower, only more recently have they investigated how insects sense and respond to such fields. Just last month, for example, a team reported that bumblebees may use electrical fields to identify flowers recently visited by other insects from those that may still hold lucrative stores of nectar and pollen. A flower that a bee had recently landed on might have an altered electrical field, the researchers speculated.

Now, in a series of lab tests, Menzel and colleagues have studied how honey bees respond to electrical fields. In experiments conducted in small chambers with conductive walls that isolated the bees from external electrical fields, the researchers showed that a small, electrically charged wand brought close to a honey bee can cause its antennae to bend. Other tests, using antennae removed from honey bees, indicated that electrically induced deflections triggered reactions in a group of sensory cells, called the Johnston’s organ, located near the base of the antennae. In yet other experiments, honey bees learned that a sugary reward was available when they detected a particular pattern of electrical field.

Altogether, these tests suggest that the electrical fields that build up on bees due to their flight or movement are stimuli that could be used in social communication, the researchers report online this week in the Proceedings of the Royal Society B.

The team’s findings “are very significant,” says Fred Dyer, a behavioral biologist at Michigan State University in East Lansing. “I hadn’t heard about the possibility that honey bees could use electrical fields.”

One of the honey bees’ forms of communication is the “waggle dance.” When the insects have located a dense patch of flowers or a source of water, they skitter across the honeycomb in their hive in a pattern related to the direction of and the distance to the site. Fellow worker bees then take that information and forage accordingly. The biggest mystery about the dance, Dyer says, is which senses the bees use—often in the deep, dark recesses of their hive—to conduct their communication. “People have proposed a variety of methods: direct contact between bees, air currents from the buzzing of their wings, odors, even vibrations transmitted through the honeycomb itself,” he says.

But the team’s new findings introduce yet another mode of communication available to the insects, Dyer says. He notes that the group found that antenna deflections induced by an electrically charged honey bee wing are about 10 times the size of those that would be caused by airflow from the wing fluttering at the same distance—a sign that electrical fields could be an important signal.

“They show that the electrical fields are there and that they’re within the range of what the animal can sense,” Dyer says. “Their claim of evidence is quite compelling.”

“Bay Area’s ‘urban’ bees like native, diverse plantings”

By Lou Fancher via mercurynews.com

Bay Area's 'urban' bees

Dr. Gordon Frankie said native bees have preferences, and knowing what they like can improve the health of your garden.

“If they have a choice, they’ll go after native plants,” said Frankie, a professor and research entomologist at UC Berkeley. He and Steve Gentry, a founding member of the Mount Diablo Beekeepers Association, teamed up for a recent Lafayette Library Foundation Science Cafe presentation.

Frankie’s point — that local gardeners hoping to attract Agapostemon texanus or Xylocopa varipuncta, two local native bee species, should include native plants in their gardening plans. And mulching should be done lightly because 70 percent of all native bees nest in the ground and can’t burrow through materials heavier than soil.

A project at Frog Hollow Farm and other Brentwood farms is demonstrating the impact of placing native plants between crop rows.

Urban areas are ideal for bees, Frankie claimed, because of the diverse food supply they offer. The Oxford Tract Bee Garden he and his team of researchers planted allows them to monitor and categorize bees’ attraction to native and nonnative plants. A 10-city survey across California is providing a detailed picture of the bee population. San Diego, he said, is the worst city for attracting bees.

“It’s their gardening culture: No one is using diverse, floral plants,” Frankie said.

On the other end of the spectrum, a 30-by-30-foot garden in Ukiah had 68 bee species, and Santa Cruz is a hotbed beehive community. (The Bay Area is fifth on that list.)

Gentry, known by local residents as “Bee Man” — although he is considering an upgrade to “Emperor of Bees” — began the popular event’s 60-minute talk with a bucket.

“All of these products from bees are helpful to humans,” he declared, pulling hunks of beeswax and jars of honey, pollen and actual bees from the container. “Their history goes back thousands of years.”

Within five minutes, Gentry had advocated (beeswax is used for lubricants in cosmetics, candles, wax-resist dyeing and food preserving), acknowledged (“We have some hindrance about eating insects, but watch a bear break into a bee’s nest. He’ll eat the whole thing,” he said), and advertised (pollen is the new superfood, with protein, enzymes, vitamins and minerals, according to Gentry).

He also shared a 30-year-old epiphany he had while watching a black bear and her two cubs demolish a rotted tree while feasting on termites.

“I wasn’t the first person to see natural things. Forty thousand years ago, hunter-gatherers watched bears, bees and insects, too. The timeline is long,” he said.

Skipping through honeybee history, from Middle Eastern origins to monks in monasteries needing dependable light sources to small farmers before World War I who kept just enough hives to feed their families and pollinate their crops, Gentry landed on the contemporary world’s bee dilemmas.

“Industrialization changed farms. They became bigger, and now, large pollination contracts and commercial beekeeping are driving the business. (More than a million) hives are brought into the central Southern California valley for pollinating almonds each year.”

Frankie, whose business is less about keeping bees and more about watching them, asked the Science Cafe audience of gardeners, beekeepers and general science fans a series of questions.

Delighting at stumping his listeners, he said 1,600 bee species were attracted to California’s 5,000 flowering plants, drawing a hefty percentage of the United States’ 4,000 total bee species.

“Notice, you are not on their list,” he said. “Bees are vegetarians. They’re not after you or your burgers. Wasps are the ‘meat bees’ after your burgers.”

Generating a local buzz
The University of California Press will publish Gordon Frankie’s findings in a forthcoming book, “Native Bees and Their Flowers in Urban California Gardens.” Bee appreciators who don’t want to wait can find information at http://nature.berkeley.edu/urbanbeegardens/index.html and diablobees.org.
