Beltsville # Test This sheet describes a simple test (a variation of the USDA Beltsville method) to check if varroa mites are resistant to Apistan.
Apistan resistant mites will almost invariably be cross-resistant to Bayvarol 1.
Cut a 9mm x 25mm piece from an Apistan strip and staple it #, Beltsville Apistan/Coumaphos double test This test can be used to determine mite resistance when a beehive doesn’t appear to respond to chemical mite control measures.
The test uses Apistan and CheckMite+TM strips and can be conducted simultaneously on the same group of colonies by taking two samples from each hive.
Beltsville , Maryland.
This test can be used to determine mite resistance when a beehive doesn’t appear to respond to chemical mite control measures.
It uses fluvalinate (Apistan), amitraz (Apivar) or coumaphos (CheckMite+TM) strips and can test all three products simultaneously on the same group of colonies by taking three samples from each hive.
Since I also can#t test for things like nosema, it just makes sense to me to send some out.

I ran my own tests tonight and, as I suspected, I#m going with varroa mites again.
7 mites per 100 on one hive and 4 per 100 on the other.
It#s funny how you can have two hives right next to each other#, 15/04/2005 New Test on Tap for Detecting Pesticide-Resistant Mites By Jan Suszkiw April 15, 2005.
Commercial apiarists and state bee inspectors now have a fast new way to check Varroa mites for this honeybee parasite’s resistance to the pesticides coumaphos and fluvalinate.

Just to remind all beekeepers that we will be hosting the National Bee Unit#s, #Beekeeper Advice Surgery#, on Saturday July 15 th from 2pm until 5pm at the Picton Centre, Freemens Way, Haverfordwest, SA61 1TP, which will cover bee diseases etc.
Details on this can be obtained NBU Advice Surgeries Flyer 2017.

“Easy-To-Use Bioassay Spots Varroa Resistance” was published in the April 2005 issue of Agricultural Research magazine.
For an additional $680 they will also test pollen samples from 16 hives (8 healthy hives and 8 crashing hives) for 170 pesticides.
Read more about this pesticide testing on pollen samples here.
After the free disease and parasite tests are complete at the Beltsville Bee Lab, they will send you and your apiary inspector a diagnosis report.
