| [important bee plants to the africanized honey bee apis mellifera l. (hymenoptera: apidae) in a fragment of savannah in itirapina, são paulo state, brazil]. | the present work had as objectives to know the bee flora composition in an savannah fragment of the estação experimental de itirapina, unit of divisão de florestas e estações experimentais do instituto florestal, in itirapina county, são paulo state, brazil (22 masculine14's and 47 masculine49'w). the pollen spectrum of the produced honey and the pollen collected by the africanized honey bee apis mellifera l. were determined in the area. the information contributes to understand the beekeeping e ... | 2008 | 19061035 |
| severe and fatal mass attacks by 'killer' bees (africanized honey bees--apis mellifera scutellata) in brazil: clinicopathological studies with measurement of serum venom concentrations. | in são paulo state, brazil, five males, aged between 8 and 64 years, were attacked by 'africanized' honey bees (apis mellifera scutellata). the estimated number of stings received by each patient ranged from > 200 to > 1000. all five were transferred to intensive care units in são paulo city. clinical features included intravascular haemolysis, respiratory distress with ards, hepatic dysfunction, rhabdomyolysis (with myoglobinaemia and myoglobinuria), hypertension and myocardial damage (perhaps ... | 1994 | 7938407 |
| inhibitory effect of propolis and bee venom on the mutagenicity of some direct- and indirect-acting mutagens. | the antimutagenic effect of ethanolic extract of propolis (eep) and honeybee (apis mellifera) venom, both collected in the state of são paulo, brazil, was assessed by the salmonella/microsome assay upon direct- and indirect-acting mutagens. eep had inhibitory effect (in an ascending order) on the mutagenicity power of daunomycin (ta102), benzo(a)pyrene (ta100), and aflatoxin b(1)(ta98) and the venom acted against the mutagenicity of 4-nitro-o-phenylenediamine (ta98) and daunomycin (ta102). terat ... | 1999 | 10587410 |
| interaction between visiting bees (hymenoptera, apoidea) and flowers of ludwigia elegans (camb.) hara (onagraceae) during the year in two different areas in são paulo, brazil. | this study was designed to characterize the interactions between ludwigia elegans flowers and visiting bees during two years in two areas 200 km apart, at the same latitude (approximately 22 masculine 48's) but at different altitudes (alumínio, 600 m, and campos do jordão, 1500 m), in the state of são paulo, brazil. as these flowers open simultaneously in the morning and lose their petals by sunset, interaction with bees occurs only during the photophase. flowers of l. elegans were mainly visite ... | 2004 | 15029372 |
