Culinary guide gives bees something to buzz about

If you were a honeybee in Michigan, hairy mountain mint and common milkweed might be your top menu choices.

If you were a Michigan bumblebee, you’d prefer chowing down on bee balm and shrubby St. John’s wort.

And if you belonged to one of the state’s 465-plus species of wild bees, roundleaf ragwort and gray goldenrod may whet your appetite.

Discovering what bees like to eat has important ramifications for growers and farmers whose apples, cherries, blueberries, squash, cucumbers, pumpkins, pears and other flowering fruits and vegetables depend on bees for pollination, said Logan Rowe, a co-author of a recently published study examining Michigan bees’ feeding preferences.

Michigan bees have different dietary preferences. These native plants top their preferred menu:
Honey bees hairy mountain mint, common milkweed, butterfly weed and showy goldenrod
Bumblebees wild bergamot (bee balm), shrubby St. John’s wort, prairie rosinweed and showy goldenrod
Wild bees roundleaf ragwort, gray goldenrod and tall tickseed

The research can help farmers and growers decide what native plants to grow near their orchards and fields, said Rowe, a zoologist with Michigan State University Extension and the Michigan Natural Features Inventory.

The study said, “Since bees obtain nearly all their nutritional requirements from pollen and nectar provided by flowering plants, the availability of these resources within bees’ flight range is crucial to their survival. Flower plantings have been shown to increase the yield of adjacent pollinator-dependent crops.”

Rowe said, “We already encourage growers to incorporate native plants,” and the findings will help them more accurately select the best seed mixtures to attract bees.

The research comes at a time of growing concern about the nation’s bees.

The U.S. Geological Survey estimates that insect pollinators, mainly honey bees, increase the value of crops in the country by more than $15 billion a year.

However, the agency said, “Critical honey bee and wild bee populations in the United States have been declining in recent years, creating concern about the future security of pollination services for agricultural crops.”

Reasons for the decline include pests, pesticides, colony collapse disorder and diseases, as well as “shifting landscapes” in the Midwest where cropland is expanding at the expense of “crucial native grasslands and conservation lands that have historically provided abundant flowers for honey bees and native pollinators,” the Geological Survey said.

Scientists conducted the Michigan study in the Northwest Michigan Horticultural Research Center in Leelanau County, the Clarksville Research Center in Ionia County and the Southwest Michigan Research and Extension Center in Berrien County.

They planted 51 species of drought-tolerant native prairie plants and two non-native species, then observed more than 3,500 honey bees, wild bees and bumblebees as they visited the flowers.

“We were seeing which were most supportive of pollinators,” Rowe said. There’s been little prior research about what types of flowering plants in Michigan’s prairie-type habitat appeal best to different types of bees.

One surprise finding is that bees in different regions of the state have different dietary preferences, he said.

Bees aren’t the only beneficiaries of targeted plantings, the study said. They also provide habitat for threatened wildlife.

The study by researchers at MSU and the University of Manitoba appeared in the journal Environmental Entomology.

  1. Fruit blossoms are available for a very short period of time, usually an orchard all blooms at once.

  2. The orchard farms require bees to pollinate the fruit blossoms.
    Do the bees not like the fruit blossoms and are need of different flowering plants?

    Or is it the time of year? Fruit blossoms are much earlier than Milkweed, etc?
