Canadian bees picking up the slack for locals
Solitary, hard working leafcutter bees are being imported from Canada to help pollinate seed alfalfa, making the crop profitable in the San Joaquin Valley, according to an article published today in Western Farm Press.
“Economically, seed alfalfa cannot compete with other crops without the leafcutter bees,” the story quoted Bob Sheesley, an alfalfa breeder who is a former UC Cooperative Extenion farm advisor and county director. Working together with honeybees, leafcutters boost alfalfa seed yield 250 pounds to 300 pounds per acre, Sheesley said.
The story was written by Dennis Pollock, who is now doing freelance ag writing after retiring from the Fresno Bee last year. For the leafcutter story, he spoke to UCCE farm advisor Shannon Mueller, who said leafcutter bees are more efficient pollinators than honeybees because they don't seem to mind being slapped in the face by the alfalfa flowers' reproductive structure as they forage for pollen.
Leafcutters won't be putting honeybees out of work, however. Honeybees are less susceptible to pesticides and are kept by professionals, unlike leafcutters, which farmers must manage and care for themselves.
