Could Probiotics Help Honeybees Recover from Nosema?
Nosema apis is a tiny one-cell parasite recently reclassified as a fungus. It causes a serious infection in bees that disrupts the health of the bee gut. The sick bee becomes not only disoriented and unable to do its normal activities such as foraging or caring for bee larva.
Nosema is one, among many threats, to the global honeybee population. The infection has been associated with colony collapse disorder. But now science has shown that healing and improved survival rates from nosema (also known as nosemosis) is possible through the aid of probiotics.
In most instances, the fungus (that bees pick up as they ingest their food) causes no harm. But stress seems to create conditions for the fungus to invade and wreak havoc on the bee’s immune system. Just as probiotics support human gut microbiota (the microbe population in the human intestine) so, too, do probiotics appear to help the bee microbiota to better deal with a nosema infection.
In a Canadian study conducted by scientists at Université Laval in Quebec City, researchers discovered that they could lower the death rate of the bees suffering from nosema from 20 to 40 percent as compared to a control group by treating the sick bees with probiotics. In particular, a probiotic (P. apium) seemed to work best in the study.
Developing probiotics with specific microbes to contend with nosema is promising. But for beekeepers and scientists searching for the causes of colony collapse disorder, the work goes on to identify sources of stress that adversely affect the immune system of bees.

Transplanting a Decades-Old Crape Myrtle Tree
Friends said it was a bad idea. The tree was too large, too old, and too unwieldy to dig up and transport from my daughter’s property to mine. The crape myrtle would not survive, they told me, because its large root would need to be severely cut. Also, without a crane or other lifting device, three of us would be struggling to deal with such a heavy tree.
I won’t say moving the tree was easy. It had been standing for 28 years next to my daughter’s house, but she wanted to make way for new landscaping. When the family decided to part with the tree, they called on a family friend who worked as an arborist. He would do the cutting and digging of the tree.
Crape myrtles (of the genus, lagerstoemia) are available as shrubs and trees and are lovely in bloom with showy paniculate flowers in pink, fuchsia, red, or lavender. They are one of the trees that make little-to-no pollen (great for allergy sufferers). Light pruning during the growing season can produce a second bloom. Much beloved in the deep south, these trees remain stately and beautiful for up to fifty years.
My daughter’s tree arrived at the farmette in mid-October strapped onto our friend’s truck. The roots had been cut away. There were no fine root hairs or stems left–just bare wood. Ditto for the tree canopy–just a few hefty branch stubs. I wondered if our efforts would prove futile.
Hubby and I prepared a large planting hole just off from the patio. We added amendments to the clay soil and drove in stakes to keep the tree stable for a year or more until it had sufficiently developed roots. I added root hormone to the soil and watered deeply the first day and several times that week.
The winter rains came. I watched, waited, and wondered if there would ever be sprouting of any kind on the woody ends where branches had been amputated. Despite a canopy, the tree’s trunk, a beautiful, gray-green wood, afforded a kind of beauty to the austere winter garden. Before spring, I scraped a fingernail on the back of the trunk and discovered the wood was not dried out but as green and moist as a young sapling.
A spell of warm weather and the buzzing of bees in early spring drew my attention upward. Our tree had sprouted a flurry of bronze-green leaves. Pink blooms will likely appear in June or July.
I’m happy now that we went to all the trouble of bringing that tree onto the farmette for transplanting. We’ll have lovely pink blooms over the remaining summers of my life thanks to the crape myrtle tree being so long-lived.
