Made in collaboration with Jacques KEMP, it reproduces the royal cell. It allows the virgin queen to be born. It is necessary to insert her that is at most one day old and place her inside the family or orphan nucleus. Before introducing inside the artificial cell the queen , wax domes of a consistent thickness must be prepared. Following this, three small aeration holes must be drilled on the same with a hot needle. At this point the queen is inserted into the dummy cell, taking care to have well applied at the end the dome. Doing so will result in an artificial cell with a selected day-old queen inside.
Varroa i fights them more effectively by zeroing out the winter brood. From this observation comes the Menna cage, designed and patented by Vincenzo Menna: a practical device that promotes the queen's rest in the colder months, and that brings all the varroa present in the Beehive more easily out into the open. The period of use varies from northern to southern Italy, but indicatively the first days of November will be the most suitable to start caging, and mid to late January those for caging. Considering that a regular family goes into production in 60 to 70 days from the release of the queen, it will be up to the beekeeper to adjust the period.
