Resumo . Este trabalho teve como objetivo avaliar a influencia diaria dos fatores ambientais e da quantidade de nectar na frequencia de forrageio de abelhas em flores de Adenocalymma bracteatum (Cham.) DC. Para isso, foi demarcada uma area focal e registrada a atividade de forrageio das abelhas em um intervalo de 30 minutos para cada hora, das 6:00 as 17:30 h, nas flores da referida especie vegetal durante quatro dias nao consecutivos. Tambem foi avaliada a producao acumulativa de nectar e o seu consumo pelos visitantes no decorrer do dia. Dados referentes a temperatura, umidade relativa do ar, luminosidade e velocidade do vento foram anotados no inicio de cada hora. Para verificar se as frequencias de forrageios das especies de abelhas estavam correlacionadas com os fatores abioticos, foram realizados testes de correlacao de Pearson. Dentre as especies registradas, Oxaea flavescens Klug apresentou o maior numero de forrageios. O numero de forrageio no decorrer do dia nao se manteve uniforme, o que faz acreditar que a atividade de forrageio das abelhas sofreu interferencia dos fatores ambientais e da quantidade de nectar presente nas flores de A. bracteatum . Os polinizadores efetivos foram responsaveis por 51,6% do total de visitas por flor em A. bracteatum , enquanto os pilhadores de recursos perfizeram 33,1% e os furtadores de recursos realizaram somente 15,3% do total de visitas por flor. Houve ainda, forrageios de formigas e moscas. As formigas sugavam nectar extrafloral, possivelmente conferindo protecao contra pilhagem de nectar. Ja as moscas pousavam na corola, mas nao extrairam nectar nem polen. Influence in the Environmental Factors and the Amount of Nectar in the Foraging Activity of Bees on Flowers Adenocalymma bracteatum (Cham.) DC. (Bignoniaceae) Abstract. This study aimed to evaluate the daily influence of environmental factors and the amount of nectar in the foraging frequency of bees on flowers Adenocalymma bracteatum (Cham.) DC. For this, a focal area was demarcated and registered foraging activity of bees in a 30-minute break for every hour from 6:00 a.m. to 5:30 p.m., in the flowers of this plant species during four non-consecutive days. Also was analyzed the nectar production and its consumption by visitors throughout the day. Data relating to temperature, relative humidity, luminosity, and wind speed were recorded at the beginning of each hour. To check if the frequencies of foraging the bee species were correlated with abiotic factors, tests of Pearson correlation were performed. Among the species recorded, Oxaea flavescens Klug had the highest number of foraging. The number of foraging during the day did not remain uniform, which makes to believe that foraging activity of bees suffered interference from environmental factors and the amount of nectar present in flowers of A. bracteatum . The effective pollinators were responsible for 51.6% of total visits per flower in A. bracteatum , while the robber’s resources totaled 33.1%, and only 15.3% of all visits were made by thieves’ resource. There was also foraging of ants and flies. Nectar present around the flower was sucked by ants, possibly conferring protection against robbery nectar. There were flies landing on the corolla of the flowers, but nectar and pollen were not collected.
