MARATHON COUNTY BEEKEEPING SEMINAR by beekeeper Fred




I was one of about seven ECWBA members that attended the bee seminar in Wausau.  One guest speaker impressed me the most; Alex Zomchek.  Besides being an excellent public speaker, he seemed to drop little nuggets of important information that I think I should pass on to ECWBA members.  So here goes. 


One, commercial beekeepers only have 7-9% winter mortality.  Much higher than that they could not remain in business.  Commercially beekeepers actively manage their hives for both low varroa, but also high honey production. Only part of that success is due to their hives going south for the winter.

Two, overwintered hives have a typical spread of 1/3 strong, 1/3 OK and 1/3 weak.  Commercial beekeepers manage those hives in the spring to even things out.  Strong hives contribute bees and brood for strengthening their weak sisters.  This does not seem to weaken the strong hives, but definitely improves the weak hives. 


Three, 95% of the stored honey is usually gathered in the 40 day period of the main nectar flow which occurs in June through early July.    This confirms my own observations.  There may be a secondary flow in the fall, but it should be left for the bees.


Four, feed early in the fall.


Five, the spring population buildup is critically important to having the hive population peaking in time for the honey flow.  Population growth is triggered naturally by the start of availability of low sugar content nectar.  In our area, with its long winters, the population growth is not triggered soon enough for the hive to always be ready for the onset of the primary June nectar flow.  A larger honey crop can be attained by giving the bees an early spring stimulative feeding.  The stimulative feeding is not the usual the 1 part sugar to 1 part water sugar syrup we normally feed new packages, but a weaker syrup mixture such as 1 part sugar to 4 parts water.  This more closely matches sugar concentration of naturally occurring early spring nectars, such as bees utilizing maple sap, and stimulates brood production.


Six, with item five above in mind, what about new packages?  We usually can get packages in three time slots; early April, late April and early May.  Since time is critical in building up the hive population after package installation it would seem logical to avoid May package deliveries.  Early April has an increased odds of inclement (ie cold) weather and is a bigger gamble for the beekeeper, but the bees can usually be successfully installed even then.  If I remember several club members got the opportunity for a few packages in early April last year and successfully hived them.  (I was always surprised at hearing of Minnesota beekeepers getting early April packages.)  So, for me the obvious plan would be as a minimum to request late April bees in the future and would even try early April bees if I were more of a gambler.

CLUB MEETING REMINDER; MARCH 23rd

Today there were geese winging their way north, sandhill cranes foraging in snow filled corn fields, and a few robins!  Drainage ditches and creeks are flowing. But the sap was not yet flowing up in a few maples I had tapped for maple syrup.  Can spring be far behind?  The moderating temperatures will definitely give the bees a break and promote brood rearing.

Remember the upcoming ECWBA club meeting on Saturday, March 23rd.  Normal place (Caestecker Public Library) and normal time (9:30AM to 11:30AM)

Next week it looks like we will be having a few days with sunny days and temperatures in the 50's.  It would be a good time to check your hive survival rates.  Survivor hives should be flying on the warm sunny afternoons.  Then you need to get replacement packages on order if required.  I am sure potential package sources will be discussed at the club meeting on the 23rd.

CHEMICAL FREE MITE CONTROL by beekeeper Fred

Many new beekeepers have high ideals and do not like the idea of controlling mites with chemicals; either natural or artificial.  By doing nothing these beekeepers will inevitably lose their bee colonies due to mite infestation.  We call these beekeepers the "Live or Let Die" crowd.  Usually after losing their bees for a few years in a row they drop out of beekeeping.

There is another path they could follow.  They could do what is called biotechnical control of mites, which keeps their populations at an tolerable level.  This methodology is labor intensive, but does yield acceptable results.  It involves drone trapping of mites, brood breaks and finally a fall split of the hive and overwintering the hives in double deep 5 frame nucs.  A beekeeper named Adrian Quiney in Hudson Wisconsin has been using this methodology for several years now with excellent results.  He regularly has 90+% winter survival of his nucs.  

Its a matter of harnessing your idealism and putting it into the extra labor needed to apply all three mite control methods.   Remember all beekeepers are simply trying to survive until the bees or beekeepers develop true mite resistant bees.  Note that mite resistant bees to date have only partially addressed the mite problem and are not a guarantee of success.

Here is link to him describing the biotechnical mite control at the 2017 Bee Seminar in Wausau, Wi.

You can also do a search while on YouTube for the name "Adrian Quiney".  The search will bring up numerous videos on the topic of overwintering 5 frame double deep nucs instead of the full size 10 frame double deep hives most of us use.

MARCH 1st APIARY REPORT




March has arrived and the days are lengthening rapidly.  We currently are getting about 11 hours of daylight and this will grow past 12 hours by month end.  However, the weather forecast shows another bout of brutal below zero nights in the coming week, but nothing like the -30F nights of a few weeks ago.  We have already had 13 below zero nights this winter not counting those yet to occur.   The good news is that meteorological spring is only 20 days away!


I went out on Thursday (February 27th) to check on hive survival.  Since my end of January count, I have lost 2 hives.  This puts me at 91.4% survival with another month of winter yet to go.  However, one hive is sounding weaker and may not survive next week’s string of cold nights.  Surprisingly, 100% of the winter nucs are still buzzing.  


In March, maple pollen will make its appearance.  Weather permitting the bees will be high up in the maples gathering the pollen to raise the new brood.  Although pollen will be available there will be no nectar.  The bees will continue to be dependent on stored honey for nutrition and heat generation.  The need to feed and warm the brood will increase the amount of food they consume to about 12 pounds per month.


If the bees deplete the honey in close vicinity to the brood nest they may starve if cold temperatures are keeping them in a tight cluster.  Now is when emergency sugar, immediately above the cluster, can save your hive.   Hopefully you have paid heed to our suggestions to add emergency sugar. 


At this point you probably have a handle on your probable survival rate.  Its time to think about ordering packages.  See if you can combine your order with other club members.  There is usually a price break when 10 or more packages are ordered.  Also consider when you want to receive your packages.  Early packages have additional time to build their populations prior to the honey flow.  The downside of early packages is that you may be installing them during inclement weather.  Conversely, late packages will arrive when the weather is generally warmer, but there will be less time for the population to build and will probably produce less surplus honey.  The choice is yours.
