Marking queens or caging them, which technique works better against varroa?

A study analyzes two techniques used to prevent the queen from laying eggs and to apply treatments against varroa more effectively. On one hand, marking queens. On the other, caging queens. We tell you what results they have found.

Many times, especially in warm climate areas, it is necessary to force the queen to undergo a forced pause in her egg-laying. Only then can treatments against varroa be applied with maximum effectiveness. To achieve this forced pause, many techniques are used, although the most widespread is caging the queen. However, a different method is spreading from China, which involves marking queens with small plastic rings.
