Wisconsin researchers offer a boost for bees

SUPERIOR, Wis. — Beekeeping has been a human activity for thousands of years. The honeybee was one of the earliest animals to be domesticated by humans.

Even so, it took humans until the 1960s to realize they could train a honeybee to stick out its tongue.

“This is very useful,” said Dr. Edward Burkett, a professor of biology at the University of Wisconsin-Superior. “We all think dogs have great noses, but a honeybee’s ability to detect scents using their antennae is 300 times better. They can be trained to stick out their tongue when they detect certain scents.”

Trained honeybees are used to detect tuberculosis in areas where testing labs are not available. At UWS, a study is in the works to determine if training honeybees to react to a particular scent can be used to detect breast cancer.

Honeybees are perhaps more widely known to the general public as master pollinators. From an agricultural perspective, they are crucially important to our economy and health. It is estimated that one-third of every mouthful of food that humans eat is pollinated by honeybees.

The honeybee is undoubtedly an important part of the ecosystem. Unfortunately, the worldwide honeybee population is in a state of dismay. By some estimates, 40-50% of honeybees in the United States have died over the past several years.

“We have to reverse this trend through education, research and outreach,” Burkett said. In 2016 he started the Urban Honey Bee Project at UW-Superior. The UHBP serves as an outreach and education initiative, but also encourages UW-Superior undergraduates to engage in research projects that study the honeybee. Some current research projects include studying the use of honeybees to monitor climate change and determining how pesticides affect a honeybee’s ability to learn and remember.

Jami Koivisto is the current president of the Head of the Lakes Beekeeping Association, a nonprofit community organization that brings new and veteran beekeepers together for education, socialization and problem-solving. Koivisto studied beekeeping under Dr. Burkett while employed at UW-Superior.

“Ed (Burkett) wants students to look at beekeeping through the eyes of a scientist,” Koivisto said. Students involved with the hives at UWS learn how to raise honeybees appropriately, with the hopes that they will continue beekeeping beyond their college years.

The UHBP wants to encourage beekeeping across the region, so extends their community outreach to interested future beekeepers off campus. “We like to see all beekeepers be as knowledgeable as possible,” Burkett said. With this in mind, the UHBP provides free beekeeping workshops aimed at educating people about sustainable methods of beekeeping.

The workshops are offered free to the general public, usually in the late winter months. At the Beekeeping 101 course, participants are asked the question: "Do I really want to raise honeybees?" The class covers topics such as honeybee biology, hive equipment and protective gear, costs, the legal issues of owning a hive, installing the bees, bee health and colony maintenance.

If participants of Beekeeping 101 find they want to learn more, Beekeeping 102 and 103 go into more depth to prepare people for setting up and maintaining their first hive. Further workshops are offered which focus on advanced issues such as swarm control, honey production and managing the hive over the winter months.

The classes encourage people to study sustainable beekeeping practices. Most of the honeybees that are ordered from large suppliers come from southern states. As of now, there are no honeybee suppliers in the upper Midwest.

“This is part of the problem with honeybee mortality rates in our area,” Koivisto said. “The most commonly kept honeybees, such as Italian honeybees and Carniolan honeybees, are not super adept at surviving our winters.”

Most hive owners do what they can to help their honeybees survive, but if their hive dies off, most owners simply order more of the same type of bee the following spring. A more sustainable approach would be to encourage propagation of a “mutt bee,” or a mixed genetic type of honeybee that is naturally more resistant to cold winters, as well as disease and parasites.

“I’ve been raising Russian honeybees in my hive,” Koivisto said. “They are a little more aggressive, but less inbred than the other two types and more likely to survive the winter.”

Every time a hive survives the winter, it is able to grow and form new hives, an essential step toward improving honeybee health.

“Honeybee health is one of the most important issues today,” said Burkett. “It is worth our time to mentor others who are trying to help.”
