Hygienic and self-cleaning behavior is very important in the selection and improvement of bee families.

The bee families that have a pronounced hygienic behavior are called good cleaners, these families are more resistant to brood diseases (loci) but also to varroa infestations.

Our apiary carries out this test of hygienic and self-cleaning behavior, families that are resistant to winter, which have a low behavior of aggression, families with prolific queens and high honey production.

A frame of capacity seedlings is harvested from the selected families, from which 5 cm2 are cut, which represents approximately 100 cells of capacity seedlings in order to freeze (practically this section is introduced in the freezer, and the seedlings die).

  

After 24 hours, the section is inserted in the place where it was cut, and the frame is reintroduced into the family from which it was removed.

Exactly 24 hours after the frame was introduced, the frozen section is checked to verify the results of the hygienic behavior of the bees. Those that removed the dead brood with a percentage of over 90% are considered suitable and become donors of larvae for growth, being considered elite families.

I would like to specify that the elite families from the “apisqueen.com” apiary had a percentage of 98% offspring removed 24 hours after the introduction of the frame in the tested families.
