During the December ECWBA club meeting we reviewed the mite
treatment programs of three local beekeepers using Randy Oliver’s varroa model. Now at the end of December, here are current
survival statistics for those three beekeepers.
Gerard’s and club hives: 100%; Jon’s hives: 95.5%; Fred’s hives: 97.3%. All three beekeepers had practiced rather
aggressive treatment programs following high losses in the previous winter. Each beekeeper used different miticides; Gerard
used Formic acid and Apiguard, Jon used Oxalic acid vapor only, and Fred used a
mix of formic and oxalic acid. How are
your hives doing? Of course, crunch time
usually occurs in mid to late January when temperatures hit their lowest for
the winter. For now, there is nothing to
do but wait for spring. We will continue
getting updates on their statistics and report them here.
We are now over the first winter obstacle. Daylight is
growing in length now that we have passed the winter equinox. For some bee types the lengthening of the day
is the que for the queen to begin laying again; albeit very slowly. This
also marks the halfway point of our six month long winter period.
During December we experienced several days of low 40’s
F. The bees were using these warm days
to take voiding flights. They also use
these warmer days to reposition the cluster closer to the remaining honey.
During winter a hive will consume one to two pounds of honey
per week. I have provided emergency
sugar to top of my hives as a matter of standard practice. There has been great variation between hives
in consumption of this emergency sugar.
Some hives haven’t touched the sugar yet, while others have consumed the
entire 2 and ½ pound disc in only two weeks.
Therefore, all hives get checked every two weeks and replenished as
needed. The reason for the large
variation isn’t clear to me, but there seems to be a slight correlation between
cluster size and sugar consumption. I
will be using the checks as an opportunity to add pollen or pollen substitute
patties next to the sugar discs. This protein will help with feeding the
new brood.
My experiment with overwintering double deep nucs
continues. Twelve of twelve nucs still
have that reassuring hum emanating from within the hives. I sure hope this experiment is successful
after seeing some of the prices being quoted for three (3) pound packages to be
delivered next spring. Prices are
ranging from $130 to $180. Yikes! High prices like this will certainly
discourage many hobbyist beekeepers. But
it might also finally convince new beekeepers that a good mite control program
is in both their and the bees best interests.
