This work was conducted to verify the brood and food area and the longevity of the workers in beehives of Apis mellifera, in established (in woods) and migratory (orange and eucalyptus) beekeeping, without (T1) and with (T2) queen excluders. In the wood, the beehives were analyzed for 476 days and mapped at intervals of 30 to 45 days to obtain the areas with brood, honey, and pollen. In the migratory, the beehives were analyzed before and after bloom. The longevity of the workers was also studied, in both treatments. The data showed that in low flow of nectar (in woods), the queen excluder demonstrated to be efficient allowing a largest separation of the honey and brood. However, when the nectar flow was high (orange and eucalyptus), the queen excluder was not efficient, due to the quicky filling out of the available combs with honey in the inferior nest, mixing it with its brood. Reduction in the longevith of the workers was also observed in T2 , in 2 of 3 tests. This work, accomplished at three different places, with different plants, evidenced the variability and the great environmental influence in the development of the colonies of Apis mellifera.
