Resumo: | The objective of this work was to evaluate the variations in the stored food resources and in the number of immature bees in Apis mellifera hives used for apple (Malus domestica) pollination. The study was conducted in the municipality of Vacaria, in the state of Rio Grande do Sul, Brazil, with 40 hives, over two consecutive harvests. The evaluations were done in the hive brood frames before, during, and 45 days after a pollination period, by interpreting photographic field records. Before being transported to the orchards, the bees foraged primarily in areas with native forest or canola (Brassica napus) crop, in 2014/2015, and with native forest or eucalyptus (Eucalyptus sp.) reforestation, in 2015/2016. In both harvests, the percentage of food resources (honey and pollen) stored in the hives reduced significantly between the pre- and post-pollination periods, but there was no significant difference between the pollination and post-pollination periods. The greatest reduction in the storage of these resources was observed in the hives from the canola crop, which had a large supply of floral resources compared with the apple orchards. The hives most susceptible to population variations within the apple orchards are those from the canola crop, whereas those from areas with a lower food supply (forest and eucalyptus) show population gains in the apple orchards. |

O estudo foi realizado no município de Vacaria, RS onde foram avaliadas 40 colmeias de A. mellifera em serviços de polinização em duas safras consecutivas (2014/15 e 2015/16). A avaliação quantitativa de recursos e população de imaturos em colmeias antes, durante e após os serviços de polinização foi realizada pela interpretação de registros fotográficos realizados a campo. Ocorreram variações significativas nas áreas de reservas de recursos das colmeias utilizadas em serviços de polinização de macieiras, diretamente relacionadas aos locais de origem. Colmeias provenientes de áreas com grande oferta de recursos foram as mais prejudicadas pela estada no pomar houve uma redução de 95 % dos recursos e de 79% na população de imaturos. Também colmeias oriundas de áreas com alta disponibilidade de recursos florais são as que menos guardam, com diminuições de 85 a 95% nas áreas ocupadas com mel e 70 a 81% para pólen.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCoordenação de Aperfeiçoamento de Pessoal de Nível Superior (Capes)Conselho Nacional de Desenvolvimento Científico e Tecnológico, process number 304081/2015-9Bizotto, Lucas de AlmeidaSantos, Regis Sivori Silva dosBoff, Mari Inês Carissimi2018-06-19info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/25103Pesquisa Agropecuaria Brasileira; v.53, n.4, abr. 2018; 399-404Pesquisa Agropecuária Brasileira; v.53, n.4, abr. 2018; 399-4041678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAenghttps://seer.sct.embrapa.br/index.php/pab/article/view/25103/14171https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/25103/16899https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/25103/16900Direitos autorais 2018 Pesquisa Agropecuária Brasileirainfo:eu-repo/semantics/openAccess2018-06-19T21:27:21Zoai:ojs.seer.sct.embrapa.br:article/25103Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2018-06-19T21:27:21Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
