Bee Gym results

This study from the Devon Apicultural Research Group was devised by Richard Ball, it is recording mite drop in the area directly below the Bee Gym and comparing it to a similar area in a control hive.

Green curve = hive with Bee Gym
Orange line = Control hive
Pink line = predicted mite drop in 7 inch square area. (22% of the total floor area). The control hive had the predicted mite drop in the 7 inch square area for much of the study.

Deryck Johnson's Trial


In this trial it is interesting to see the immediate impact the Bee Gyms (in hives 7 and 8 coloured green and red) have when introduced to the hives.

After adding in Apivar (Amitraz) the Bee Gym hives show much less of an increased mite drop, compared to the other hives.

Bob Maurer's Trial


Bob's Trial Graph

The control hives (3A and 5) have now had chemical treatment. Hives 1 and 2 are continuing with the Bee Gyms.


In the picture below the mite drop pattern on the sticky board is from a test hive, over three days in early October. The empty frame is there to reference the dimensions of the Bee Gym in the middle of the mesh floor above. In this test hive, the mite drop went from an average of 24 per day to 80 per day, then 145 per day as soon as new versions of the Bee Gym were introduced.

Mite fall in     April   May   June   July   Aug   Sep   Oct


The Bee Gym was added in late April.

In mid May the mite level dropped from 6 per day to 3 per day. By July it was down to 2 mites per week (a similar result to Peter's colony). Their hive went on to produce 3 full supers of honey this year.

There could of course be lots of other factors contributing to these results. The Bee Gym will have to be tested in many more hives before it is possible to draw any conclusions about its potential.

Graph A: Peter’s Hive Spring 2013


Mite fall in     March   April   May   June


The Bee Gym was added on 26th March.

Results from this hive are currently less than 1 mite per week. The colony is going into winter with no other form of treatment.

The point of this graph is to show a colony with a low but significant mite drop level in March. Then the Bee Gym was added. The level went up threefold then came down gradually and is now at zero.

Graph B: Stuart’s Hive 1 Winter 2012/13

Mite fall in     November   December   January   February   March


On the 3rd October a ¼ dose of Thymol (Apilife Var) was added.

The point of this graph is to show that the bees were working with the bee gym during the autumn and winter and the mite drop levels gradually went down to zero. This colony did not build up mite levels in spring, but died out in April as they didn't have enough bees to keep warm in the prolonged winter.

Graph C: Stuart’s Hive 2 from Autumn 2012


Mite fall in     August   September   October   November


The Bee Gym was added on 6th September 2012.

In this hive the mite level went up again and the bees were treated with Apivar. The levels have stayed very low throughout 2013 so no further treatment will be used this year.

This graph illustrates how adding in the gym causes rapid changes to mite drop levels.
