Résumé partiel
It Africanized honey bees (Apis mellifera L.) have high swarming behavior and high adaptability, characteristics that allowed the rapid propagation of these bees in tropical conditions. However, africanized honey bees have been causing problems in Brazilian cities due to the high risk of accidents that they can cause to people and animals, because they have a strong defensive instinct. This work was carried out on the Federal University of the Semi-Arid Region. The main objective of this research was to evaluate the characteristics of feral swarms of africanized honey bees in Mossoró city, in order to gain a better comprehension of the biology of these bees in urban áreas, understanding the possible factors involved in the nesting and swarming process in cities in the semiarid region of Northeast Brazil. For this, through a partnership between UFERSA and the Fire Brigade of Mossoró, 487 swarms were notified from requests made by the local community during the period from april 2015 to march 2018. In each notification of the presence of bees, various information about the swarms was recorded as : date, address, height and structure of the place where the bees were found, presence or not of nesting, position of the combs, estimate of the number of bees in the swarm, defensiveness of bees, presence of queen, queen cells, drones and combs with drone cells. Data on rainfall, air temperature, relative humidity, solar radiation and wind speed were obtained in order to evaluate the effect of climatic variables on swarming and reproductive aspects of swarms. The results showed that in urban areas of the northeastern semiarid region the swarms invest in reproduction and swarming throughout the year, however, the breeding of queens and drones is intensified in the rainy season, while the swarming peak occurs between the end of the rainy season and beginning of the dry season, which is between the months of april and september. Natural production of queen and drones in the colonies was negatively affected in periods of higher temperature, solar radiation and wind speed.
