| We evaluated the infestation rate (IR) of the ectoparasite mite Varroa destructor in hives of the Africanized honeybee Apis mellifera in 10 commercial apiaries located in the municipality of Juquitiba (Vale do Ribeira, São Paulo, Brazil) during two seasons (summer and winter). From each apiary, three colonies were randomly selected for collection of bee samples in each season. The average mite IR was 7.3%, when pooling both seasons. For the summer period the average IR varied from 1.1 to 11.6% (KW = 25.9191; p < 0.01). For the winter period, IR values were observed ranging from 0.3 to 19.1% (KW = 18.7760; p < 0.05). In only three of the studied apiaries did the IR remain unchanged over both seasons, even though it tended to be higher during the... |

| The aim of this study was to investigate the polliniferous floral sources used by Apis mellifera (L.) (africanized) in an apiary situated in Pará de Minas, Minas Gerais state, and evaluate the pollen prefences among the beehives. Two beehives of Langstroth type with frontal pollen trap collectors were used. The harvest was made from September 2007 to March 2008, with three samples of pollen pellets colected per month per beehive. The subsamples of 2 grams each were prepared according to the European standard melissopalynological method. A total of 56 pollen types were observed, identifying 43 genus and 32 families. The families that showed the major richness of pollen types were: Mimosaceae (8), Asteraceae (6), Fabaceae (3), Arecaceae (3), Euphorbiaceae... |
