  • Bee Diary: May 9, 2011 Wax Moths

    Beltane                                                                       Waxing Last Frost Moon

    Minnesota Hobby Bee Keepers last night.  There’s always something at these events.  Last night Gary Reuters, Marla Spivak’s associate and bee wrangler, took general questions on hive management.  He does this every meeting, but he took more time last night.  I learned about wax moths.  Wax moths, which come on the winds of mid-summer, infest hives and ruin the comb.  If all the hive box frames are on colonies by July, this is not a problem because the bees fend them off.  Then, when the season is over, any frames left out of a hive box go into the cold shed and the moth larvae die over the winter.

    Here’s the interesting part.  The function of the wax moth is to invade vacated bee colonies and reduce the comb and other residue, like propolis, to a substance more usable by the rest of nature.  In other words the wax moth is another aspect of the intricate dance in which the bees participate, a natural part.  The number of things bees can teach us seems, at this stage in my learning, as numerous as the pollinators themselves.

    Fall                                  waning back to school moon

    Marla comes to all the hobby beekeeper meetings.  She also taught the Beginning Beekeeping Course.  She’s bright, quick and has the power to explain things simply.  Good choice, MacArthur.

    “Marla Spivak’s work with bees and their keepers has earned her a $500,000 “genius grant” from the John D. and Catherine T. MacArthur Foundation.

    Spivak is a distinguished professor of apiculture and social insects at the University of Minnesota, but earned her doctorate in 1989 at Kansas University, where she studied under Chip Taylor, professor of ecology and evolutionary biology.

    Her work on honeybees’ health has helped protect honeybee populations from disease.

    She has focused on genetically influenced behaviors that make entire colonies resistant to disease, and has bred more disease-resistant strains of bees for use throughout the industry.

    The genius grants provide money based on creativity, originality and potential to make important contributions in the future. Other fellows from this year include an indigenous language preservationist, a stone carver and a quantum astrophysicist.

    No stipulations are placed on the monetary awards. Fellows are nominated and selected in secret by people whose anonymity is carefully guarded.

    Taylor on Tuesday praised Spivak’s work, saying she was unique among scientists in the field. “She works more closely with beekeepers than any of the researchers I’ve ever known,” he said. “She’s been extremely successful in getting them to cooperate.”

    As a result, he said, her research more than others’ has had an impact on more people.

    “She’s absolutely dedicated to both the science that she’s doing and the industry that she’s working with,” Taylor said.”

    Beltane                                  New Moon

    On Tuesday night I attended my first meeting of the Minnesota Hobby Beekeepers Association.  Down a muddy road near the practice field for women’s soccer at the corner of Larpenteur and Cleveland in St. Paul, part of the St. Paul campus of the U. of M., lie a small, old complex of buildings that house the bee research facilities for the UofM.  They’re not much to look at.  The bee yard has knock down chain link fence around its blue, gray and tan hive boxes.  A building that would fit well on a run down farmstead in northern Minnesota seems to house bee equipment and a more modern, but well used building with a truck dock and sliding door completes the place.

    It would be a mistake to take this as a reflection of the quality of the work done by Marla Spivak, her bee wrangler Gary and a small flock of grad students.  Some of the finest bee research on colony collapse disorder has been done here as well as the development of a strain, the Minnesota Hygienic, specifically bred to combat it.

    When I arrived, the loading dock area had a crowd of maybe 50 people, most, like me, under dressed for the 43 degree rainy weather.  A smattering had bee suits.  We had been asked to bring them since there would be a live demonstration of dividing a hive.  I brought mine and put it on, not to protect me from the bees but from the chill in the evening air.

    Two young female grad students got out the smoker, cracked the hive boxes and went through the various moves necessary to complete the division of an over-wintered colony into a parent and a child colony.  I did this a couple of weeks ago, so it was review, but helpful anyhow.  I had not, for example, tilted the queen cage up so the syrup would not drown her in case it entered her cage.  I had also forgotten to remove a frame way earlier, though I did do that on the day I divided the colony.

    This was very informal with frames passed around so folks could see larvae, identify drone cells, that sort of thing.  There were a lot of absolute newbees there.  I felt I had a bit of experience on them, but not much.

    After that we retired to Hodson Hall on the campus about a quarter of a mile from the bee yard.  There we sat in tiered seats, an entomology class room, evident by the row of glass cases outside containing japanese beetles, cotton moths and water borne larvae.  This was informal, too, consisting of a few presentations.

    One guy had a method apparently used in Canada to increase the field force available to one set of honey supers.  This involves two hive boxes set side by side with a queen excluder over half of each.  A board covers the exposed part of each hive box.  This allows two queens to lay eggs, increase the number of worker bees.  The honey supers get filled up quicker and with better drawn comb for comb honey.

    Another guy brought a beautiful top-bar frame in with a free formed comb.   Then we had pizza, mingled a bit, heard another presenter, and left.  This will be a useful group as time wears on.
