diversity in bee (hymenoptera: apoidea) and social wasp (hymenoptera: vespidae, polistinae) community in "campos rupestres", bahia, brazil.	hymenoptera such as bees and social wasps are regular floral visitors in "campos rupestres" vegetation. a community of bees and social wasps was studied during floral visitation in an area of "campos rupestres", at chapada diamantina, ba, brazil, from september 2001 to april 2002. the community was described in relation to diversity, evenness, and dominance rank, considering the individuals abundance (h' = 2.14/ j' = 0.55) and biomass (h' = 2.34/ j' = 0.60). thirty nine bee (588 individuals/ 15. ...	2006	17348126
spatial analysis of migrating apis mellifera colonies in salvador, bahia, brazil.	beekeeping in brazil is growing but also associated with an increase in the number of human and animal accidents involved. in particular, bees of the apis mellifera species (africanized bees) are known for their aggressive behaviour and frequent swarming activity due to their poor adaptation to the human environment. this study analyzed the spatial distribution of occurrences of migratory swarms of a. mellifera and recorded apicultural accidents in the city of salvador, bahia, brazil. the associ ...	2009	19908195
pollination efficiency of apis mellifera linnaeus, 1758 (hymenoptera, apidae) on the monoecious plants jatropha mollissima (pohl) baill. and jatropha mutabilis (pohl) baill. (euphorbiaceae) in a semi-arid caatinga area, northeastern brazil.	previous studies have shown the superior competitive ability of honeybees compared with native bees in the exploitation of floral resources and nesting sites besides their low efficiency in pollinating native plant species. however, there is little evidence of the effect of this invading species on autochthonous plant populations in natural environments. thus experiments were performed to test the pollination efficiency of honeybees in two species of jatropha (euphorbiaceae), j. mollissima (pohl ...	2011	21437406
frequency and foraging behavior of apis mellifera in two melon hybrids in juazeiro, state of bahia, brazil.	the study was carried out to verify if there are differences in foraging frequency and behavior of apis mellifera in two melon hybrids (10:00 - 'yellow melon' and sancho -'piel de sapo') in the municipality of juazeiro, state of bahia, brazil. the frequency, behavior of visitors and the floral resource foraged were registered from 5:00 am to 6:00 pm. there was a significant difference in the frequency of visits when comparing hydrids (f = 103.74, p <0.0001), floral type (f = 47.25, p <0.0001) an ...	2014	25590739
pollen types and levels of total phenolic compounds in propolis produced by apis mellifera l. (apidae) in an area of the semiarid region of bahia, brazil.	twenty-two propolis samples produced by apis mellifera l. in an area of the semiarid region the the state of bahia (agreste of alagoinhas), brazil, were palynologically analyzed and quantified regarding their levels of total phenolic compounds. these samples were processed using the acetolysis technique with the changes suggested for use with propolis. we found 59 pollen types belonging to 19 families and 36 genera. the family fabaceae was the most representative in this study with nine pollen t ...	2014	24676176
