Strengthen colony-level defense against mites and disease with UBeeO™

UBeeO™ is a groundbreaking new tool designed to accurately predict a colony’s ability to self-manage mites and disease through hygienic behavior – a vital aspect of colony health.

What is hygienic behavior?


Brood stressed by mites, viruses, or other diseases emit special pheromones through the wax cap 


Patrolling nurses detect the pheromones and locate the unhealthy brood for further inspection



The nurses uncap and remove the unhealthy brood to prevent the spread of mites and disease, protecting the colony

Hygienic behavior is a heritable trait that beekeepers can selectively breed for. Colonies that are more hygienic are more sensitive to unhealthy brood pheromones, and thus more resistant to mites and disease. 

Stronger bees with


Optera’s UBeeO™ mix contains naturally occurring brood pheromones. To test a colony’s sensitivity, the UBeeO™ mix is applied to a small area of capped brood. The colony’s hygienic response to the treated brood cells after two hours indicates its ability to resist mites and disease throughout the season. 

Here's how it works:

Apply UBeeO™

Spray the UBeeO™ mix onto a small test area of capped brood and return the frame to the colony

Let the bees work

Hygienic worker bees will respond to UBeeO™ by uncapping brood cells in the test area 

Calculate UBeeO™ Score

After just two hours, the colony’s UBeeO™ response is ready to be graded


The UBeeO™ Score is the percentage of cells uncapped by the end of the testing period – the more cells uncapped, the higher the score 

UBeeO™ Scores can fall into three categories:

Low UBeeO™ Scores


Medium UBeeO™ Scores


High UBeeO™ Scores


Peer-reviewed data show that untreated High UBeeO™ colonies are able to maintain mite loads below treatment thresholds and are more likely to overwinter.

Low UBeeO™ colonies may require additional mite monitoring and treatment to improve survival chances.


UBeeO™ in the beekeeper's toolbelt

Combined with skilled management and beekeeper intuition, UBeeO™ can guide you in improving apiary management through achieving and maintaining mite and disease resistance.
