-(Brownish propolis from the Atlantic coastal areas in the state of Rio de Janeiro, Brazil: a palynological approach). Several ecosystems appear along the coastline in Rio de Janeiro State where apicultural activities are developed for propolis production, although only a few papers have been published on palynological analysis of the propolis produced in this region. Twenty four samples of propolis were collected and analysed throughout 1997, originated from three apiaries located in distinct areas on the west Atlantic coast in the municipality of Rio de Janeiro. The palynological analysis was carried out after removal of wax and resin using ethanol, acetolysis, and counting 500 pollen grains per sample. All samples showed a predominance of Eucalyptus pollen type together with Mimosa caesalpiniaefolia apart from minor quantities of Mimosa scabrella. Cecropia was present in most samples but the percentages varied considerably. Anacardiaceae (four pollen types), Asteraceae, Citrus, Cocos and Poaceae also occurred in most samples, but in lower quantities. The original vegetation in this region (Atlantic forest and "restinga") was represented by a few pollen types with percentages below 3% (Astronium, Casearia, Celtis, Mansoa/Sparattosperma, Myrcia, Schinus and Tabebuia). Statistical analysis refl ected the correlation between the plant species identifi ed by their pollen grains and the studied areas. The palynological analysis of the brownish propolis showed mainly the similarity of the pollen spectra in these three areas, making evident the altered vegetation (from degraded areas and cultivation).Key words -Apis mellifera, palynological analysis, propolis, Rio de Janeiro, vegetation RESUMO -(Própolis marrom da vertente atlântica do Estado do Rio de Janeiro, Brasil: uma avaliação palinológica). Diversos ecossistemas são encontrados ao longo da área litorânea do Estado do Rio de Janeiro onde se desenvolvem atividades apícolas visando à produção de própolis, entretanto, poucos são os trabalhos que tratam da análise palinológica da própolis dessa região. Foram analisadas vinte e quatro amostras de própolis coletadas ao longo do ano de 1997 e procedentes de três apiários localizados em áreas distintas da vertente atlântica na zona oeste do município do Rio de Janeiro. As análises palinológicas foram realizadas a partir da remoção da cera e resina com etanol e, pelo uso da acetólise, contando-se 500 grãos de pólen por amostra. Em todas as amostras houve a predominância do tipo polínico Eucalyptus em conjunto com Mimosa caesalpiniaefolia, além de Mimosa scabrella que, no entanto, foi observado com valores mais baixos. Cecropia esteve presente na maioria das amostras, mas seus percentuais variaram muito. Anacardiaceae (quatro tipos polínicos), Asteraceae, Citrus, Cocos e Poaceae também ocorreram na maioria das amostras, mas sempre com baixos valores. As formações vegetais originais da região (mata atlântica e restinga) foram representadas por alguns tipos polínicos com percentuais abaixo de 3% (Astronium, Casear...

“…Likewise, knowledge of plant species based on pollen and nectar sources contributes to the characterization and origin of the resource used (Carvalho et al 2001). When performed on a monthly basis, such analyses also provide valuable floral calendars for further studies (Luz et al 2007) and contribute to maintaining bee pasture.…”

We applied an "adapted" protocol for collecting and processing pollen grains in the pollen analysis of the post-emergence residue of Melipona (Melikerria) interrupta Latreille. The study was conducted at the Sant' Ana honey farm, located on the banks of the Solimões River, in the municipality of Manacapuru, in the state of Amazonas, Brazil, where a colony was monitored in October and November 2010. From that colony, 10 samples of post-emergence residue were collected. Unlike in the acetolysis method, there was no need to expose pollen grains to an acidic medium, because pollen loses its content during the larval digestive process. We identified 32 pollen types, from 19 botanical families, plus three undetermined pollen types. The most representative family was Fabaceae (Mimosoideae), with eight pollen types, Mimosa guilandinae being the most common species. Only the pollen of Miconia (Melastomataceae), with 74.10%, was classified as a common pollen. We also found that the pollen of Mimosa pudica (Fabaceae: Mimosoideae) retained its content, indicating that not all resources furnished by workers are utilized by the larvae. The protocol applied here, despite omitting the acetolysis process, was efficient, providing full details of pollen contained in post-emergence residue.

“…In the laboratory, the refrigerated samples were subjected to melissopalynological analysis, without acetolysis (Louveaux et al, 1970;Barth and Luz, 1998;Luz et al, 2007) and measurements of water activity (Aw). The total microbiota count and isolation was performed using Petri dishes by the serial dilution method (Pitt and Hocking, 2009).…”

The Brazilian Sac Brood is a disease that affects apiaries of Africanized bee hives in Brazil, thereby making them susceptible to high losses. This study investigated the pathogenicity of Africanized bee hives by the entomopathogenic fungi in a Brazilian Sac Brood endemic region. The degree of fungal contamination, presence of mycotoxins in beehive elements, and vulnerability of healthy beehives in environments subjected and not subjected to the disease were investigated. From the contaminating fungal load, species that are mycotoxin producers and pathogenic causing mortality in the bees have been isolated. The analysis of bee pollen and bee bread samples did not show the presence of the toxic pollen of Stryphnodendron (Fabaceae), which has been indicated as the causative agent of mortality in pre-pupal stage larvae. However, bee bread showed the highest correlation between substrate and fungal contamination.Keywords: bee health, beekeeping, molds, mycotoxins RESUMO A cria ensacada brasileira é uma doença que afeta apiários de colmeias de abelhas africanizadas no
