I thought it was interesting that while almost 50% treated for nosema,
only 21% even checked to see if they had it.
Hello Peter,
Monitoring for Nosema is still a problem. Beekeepers don't like to use
microscopes. However, if you check the report. Alberta did not provide all
our program details due to Freedom of Information Act. In Alberta
surveillance program, we have at least 75% of the bees sampled for nosema
in 2009 and 2010. Most of 2010 fall samples were collected last week. I
have two more beekeepers left to do this week. We collect 24 samples/
operation in spring and 24 more samples in the fall, A total of about 5000
are collected and examined for nosema. We examine 30 bees/hive for nosema.
The averages of nosema spores per apiary and per operation are calculated
. Detailed reports about nosema per hive, per apiary, and per operation
are delivered to beekeepers with recommendations to take actions as
needed. As we implemented this program since 2009, overall the average
nosema levels went down by almost 80%. We are still working with our
beekeepers to train them and encourage them to do the microscopic
inspections. Many commercial beekeepers bought microscopes (The $500
microscope deal). We trained some of them and we will continue to train
more for them on how to use microscopes. Beekeepers are moving ahead to
carry on their monitoring by themselves. It is a good change. I am sure
that monitoring varroa and nosema and taking action on time, will help in
restoring bee health. In Alberta winterkill went down from 30% over the
past 3 years to 17.5%. It is almost the same as the long term average for
winterkill (15%) in the past 20 years before 2006/2007.
