resUMoEste estudo objetivou identificar uma alimentação eficiente para as abelhas Apis mellifera L. utilizando um complexo enzimático para melhorar o desempenho dos enxames em períodos de escassez alimentar. Para isso, quadros de cria fechada foram retirados de duas colmeias, conduzidos até uma câmera climatizada e após a emergência, as abelhas foram mantidas em unidades experimentais para serem alimentadas. A dieta utilizada na pesquisa foi composta por 60% de mel, 30% de farinha de soja e 10% de farinha de milho, com diferentes níveis de inclusão (0,00%, 0,03%, 0,06%, 0,09%) do complexo enzimático em estudo. Os parâmetros avaliados foram: longevidade das abelhas, concentração de proteína total da hemolinfa e consumo de água e dieta. Não houve efeito toxicológico de acordo com análise de sobrevivência, verificou-se uma redução no consumo, conforme foi acrescentado o complexo enzimático na dieta e um aumento no teor de proteína na hemolinfa. O uso do complexo enzimático mostrouse como uma ferramenta para manter os enxames em períodos de escassez de alimento, pois proporcionou melhor aproveitamento dos alimentos por menor consumo da dieta e o maior teor de proteína total na hemolinfa. Enzymatic complex in artificial feeding of africanized bees sUMMarYThis study aimed to identify efficient feed for Apis mellifera L. bees using an enzyme complex to improve the performance of the swarms in periods of food scarcity. In order to achieve this objective, closed brood frames were removed from two beehives, led to a climatic chamber and after the emergence of the bees, they were kept in experimental units to be fed. The diet used in the research was composed of 60% of honey, 30% of soy flour and 10% of corn flour, with different levels of inclusion (0.00%, 0.03%, 0.06%, 0.09%) of the enzyme complex. The parameters evaluated were: longevity of bees, concentration of total protein in the hemolymph, water and diet consumption. There was no toxicological effect according to the analysis of survival and a reduction in consumption was observed as the enzyme complex was added in the diet and an increase in the protein content of the hemolymph. The use of the enzyme complex turned out to be a tool to keep the swarms in periods of food scarcity, because it provided a better utilization of food by less consumption of the diet and the highest content of total protein in the hemolymph. additional keYwordsHemolymph.

Muitos ingredientes foram utilizados para formular dietas artificiais para as abelhas, porém muitas deles sem êxito na manutenção da postura da rainha.

Bees play an important role in maintaining biodiversity by promoting the pollination of numerous plant species. Recent global climate changes are affecting the average air temperature, thereby altering the biological processes of many species. The objective of this study was to evaluate the adaptation of Apis mellifera L. bees to temperature increases and their responses to thermal homeostasis in the colony. Research was performed at the Federal University of Paraíba Laboratory of Bees using three treatments: Control, 33 °C and 40 °C. For the latter two treatments, colonies were kept in a 24 m² climate chamber with an opening at the hive entrance, giving the bees access to the outside environment. The following parameters were evaluated: difference between internal and external hive temperature, thorax surface temperature and total protein concentration in the hemolymph. Internal colony temperature varied according to the external hive temperature. Nurse bees that care for larvae exhibited higher heat production, expressed as thorax surface temperature. Total protein content in the hemolymph was highest in the 40 °C treatment and decreased with ambient temperature. External hive temperature influences internal hive temperature, and nurse bees have higher capacities for thermogenesis.
