- Heavily infested test colonies in a Tucson Apiary
- Treatment administered and >200 mites dropped per day, controls remained constant
- Normal colony behavior was observed during and after treatment
|
 |
- Repeated November study in a commercial setting and compared vs two industry standards
- Significant mite drop was noted and comparable to standards
- At the studies end (49 days) mite reduction was maintained and both brood and frames of bees increased in the HopGuard™ treated colonies, however not statistically significant
|
 |
- Expanded on the December trial with very heavily infested commercial hives in Northern California
- Significant mite drop with normal colony behavior observed in all treated hives during and after treatment with HopGuard™
- The tests were done in queen production operations and did not interefere with queen development nor was drone sterility detected
- Long-term colony health was noted, however due to the severe mite infestation, a repeat treatment after 8 weeks was required
