- Abstract
The pollen of some Stryphnodendron species (Mimosoidea), commonly known as barbatimão, has been identified as a causative agent of pre-pulps larvae mortality, observed in Brazilian sac brood disease (BSB). The goal of this study is to identify the pollen types found in samples of pollen collected by Apis mellifera L. to elucidate the floral diet used by this honeybee specie in Rio de Janeiro state during the periods where BSB usually occurs. Particular attention was given to the pollen of Stryphnodendron spp presence. Samples of pollen and bee bread were collected from seven apiaries located in Rio de Janeiro state, Brazil. Sampling procedures were done a month before BSB usual occurrence and also during its occurrence. Leguminosae, Euphorbiaceae, Asteraceae, Poaceae and Myrtaceae were most representative botanical families on pollen sampling. Pollen from Stryphnodendron was not presented at the analyzed samples. In order to Stryphnodendron absent at the floral diet of Africanized hives affected by BSB in natural conditions, it is proposed another causal factor for BSB in the state of Rio de Janeiro.
