Sobrevivência de Apis Mellifera alimentadas com diferentes concentrações de pólen de Myracrodruon urundeuva em condições de laboratório.

Abstract

The native tree species of the Northeast Region presents important honey producing features. The Myracrodruon urundeuva (aroeira) stands out because its flowers produce nectar in abundance and male flowers with showy anthers that provide pollen for bees. Within the group of plant species considered of bee plants which exhibit toxicity effects may cause death of adult bees and young. In this sense, seeking the importance of bees this work aims to evaluate the effect of pollen M. urundeuva, added to the diet, the survival of worker bees (Apis mellifera) kept in controlled conditions in the laboratory. The work was conducted in Lab of bee and Lab of nutrition of the Federal University of Campina Grande, Campus Pombal. The pollen was collected from inflorescences of plants of M. urundeuva at the Paraibano Hinterland. Were used newly emerged worker bees of A. mellifera and forming groups 20 bees corresponding to a repetition of the experiment. The captured bees were placed in wooden cages. The study used a completely randomized design, with five treatments in four replications. In control group (T0) received water and paste-candy like food, the experimental groups the pollen amounts were incorporated in the diet in the concentrations of 0.25%, 0.50%, 0.75% and 1.00% in relation to 10g of paste-candy. The lifting of the number of dead bees was recorded daily. The toxicity of M. urundeuva pollen was measured per period to achieve total mortality of bees in the cage (PTMC), mortality index (MI) and the mortality average time (MAT) of the confined bees. It was observed reduction in the survival of A. mellifera with the use of diet containing concentrations pollen of M. urundeuva, it´s been the treatment with high concentration of pollen showed the lowest survival curve, suggesting that there is a toxicity potential of pollen of Aroeira on the workers of A. mellifera kept in confined conditions in the laboratory.
