O princípio básico era ofertar ninhos alternativos para os apicultores que trabalham com abelhas africanizadas (Apis mellífera). Para o cálculo do custo unitário de cada ninho foram considerados os preços atuais das matérias primas, bem como as suas depreciações anuais. Constatou-se uma economia de até 30% na construção dos ninhos alternativos quando comparados aos custos dos ninhos tradicionais de madeira, mostrando-se uma opção viável e rentável ao apicultor. Em relação ao comportamento das abelhas, concluiu-se que o tipo de material (concreto ou madeira) utilizado na construção dos ninhos não teve influência significativa na agressividade das mesmas. A defensividade, fortemente atrelada a fatores genéticos, pode ser em função do grau de africanização e do local de instalação dos apiários. / The objective of this work is to analyze the economic feasibility and acceptability of nests Langstroth hives made of concrete-based construction wastes. The basic principle was to offer alternative nests beekeepers working with Africanized honeybees (Apis mellifera). In order to calculate the unit cost of each nest, it was considered the current commodity prices, as well as its annual depreciation. It was found that there were savings of up to 30% in the construction of alternative nests when compared to the costs of traditional wooden nests, which can be seen as a viable and profitable option to the beekeeper. As for the behavior of the bees, it was concluded that the type of material (concrete or wood) used in the nest construction had no significant influence on the bee aggressiveness. Defensiveness, strongly linked to genetic factors, may be a function of the Africanization level and location of installed apiaries.
