Varroa Sensitive Hygiene and Mite Reproduction

The USDA-ARS Baton Rouge Bee Lab has bred bees that hygienically remove mite-infested pupae from capped worker brood. This ability is called varroa sensitive hygiene, and bees expressing high levels of this behavior are called VSH bees. To select for the VSH trait in your bees, also see Selecting for Varroa Sensitive Hygiene

Figure 1. Hygienic removal of a mite infested worker pupa by adult worker honey bees is an important mechanism of resistance to varroa mites. The removal involves

Powder Sugar Roll for Varroa Sampling

To keep your honey bee colonies healthy, it is important to determine the level of varroa mites in your colonies. This method provides a good estimate of the number of varroa mites on the adult bees. This method has the advantage of not killing the bees.


  • The methods described here are illustrated in the following University of Minnesota Instructional Poster “Powder Sugar Roll For Varroa Mites on Honey Bees” Download a .pdf here.
