Abstract

The Varroa destructor mite has caused the death of hundreds of thousands of Apis mellifera colonies in several countries worldwide. However, the effects determined by the Varroa mite change according to the A. mellifera subspecies. In Africanized bee colonies from South and Central America, the parasite causes little damage, as the infestation levels are relatively stable and low, thus treatments against the pest are not required. Among several factors, the grooming behavior of Africanized worker bees plays an important role in the maintenance of the low infestation levels. This study determined the daily rate of live and dead mites found at the bottom of the hive in five Africanized honey bee colonies. During fifteen days of observations, a significant increase was verified in the number of live and dead mites at the bottom of the hive as the amount of worker broods from each honey bee colony decreased. This suggests a more intense grooming activity as the Varroa concentration in the adult honey bee population increases.
