          Abstract

          Propõe-se a análise das atividades de vôo de Melipona marginata obscurior Moure, 1971, em diferentes épocas do ano. Atividades de vôo de abelhas de duas colônias foram estudadas no Centro de Pesquisas e Conservação da Natureza Pró-Mata, em São Francisco de Paula, RS. Na primavera-verão, a amplitude diária de atividade de vôo foi de nove e 13 horas para colônias A e B, respectivamente, com maior intensidade de vôo entre nove e 11 horas. A temperatura mínima para vôo foi de 14,3°C e a partir desta tornaram-se mais intensas. A maior intensidade de vôo ocorreu na faixa de 81-90% de umidade relativa e radiação solar a partir de 300 W/m². Para a colônia A, apenas a temperatura influenciou significativamente as atividades de vôo das abelhas, enquanto que para a colônia B foi somente a radiação solar. No outono-inverno, a amplitude diária de atividades de vôo foi de 10 horas, e entre 10 e 15 horas estas atividades foram mais intensas. A temperatura mínima para vôo foi de 13,7°C, e a partir desta temperatura as atividades tornaram-se mais intensas. Assim como na primavera-verão, a maior intensidade de vôo neste período ocorreu a partir de 300 W/m² de radiação solar. A temperatura e a radiação solar exerceram influência significativa nas atividades externas das abelhas das duas colônias no outono-inverno. As atividades de coleta de pólen pelas abelhas, na primavera-verão, ocorreram desde as primeiras horas da manhã, enquanto no outono-inverno o forrageamento foi tardio.

          Translated abstract

          It is proposed a seasonal analysis of the external activities of Melipona marginata obscurior Moure, 1971, in different times of the year. The flight activities of the bees of colonies were studied in the Centro de Pesquisas e Conservação da Natureza Pró-Mata, at São Francisco de Paula, Rio Grande do Sul. In the spring-summer period, the diary amplitude of the flight activity was about 9 and 13 hours to the colonies A and B, respectively, with more flight intensity between 9 and 11 o'clock. The flight minimum temperature was about 14,3°C and from this one they became more intense. The most flight intensity has occurred about 81-90% of relative humidity and 300 W/m² of solar radiation. For the A colony, the bees flight activity was significantly influenced only by the temperature, while for the B colony it was influenced only by the solar radiation. In autumn-winter period, the diary amplitude of the flight activities was about 10 hours, and between 10 and 15 o'clock these activities were more intense. The flight minimum temperature was about 13,7°C, and from this temperature the activities became more intense. As in the spring-summer period, the most flight intensity in this period had occurred in about 300 W/m² of solar radiation. The temperature and the solar radiation had exertised a significant influence in the external activities of the bees on both colonies in the autumn-winter period. The collect pollen activities by the bees, in the spring-summer period, occurred in the first hours of the morning, while in the autumn-winter period the foraging was delayed.

          The Bees of the World

          A comprehensive, worldwide treatment of all groups of bees - 1200 genera and subgenera, including more than 16,000 species. In extensive introductory sections, Charles D. Michener examines the evolution of bees from wasps, the relations of the families of bees to one another, the evolution of bees in relation to that of flowering plants, the nesting behaviour of solitary and social bees, and the structure of immature and adult bees. Drawing on these considerations as well as the fossil record, he speculates on the attributes of the protobee, the common ancestor of all bees. He also cites the major literature on bee biology and describes the need for further research on the systematics and natural history of bees, including their importance as pollinators of crops and natural vegetation.
