<p>As abelhas melíferas são de suma importância para a diversidade biológica dos ecossistemas, sendo as mais usadas a serviço da polinização de plantas, por causa das suas características e adaptação das estruturas florais. O objetivo do presente trabalho foi realizar uma revisão literária sobre os estudos relacionados a biologia das abelhas, visando a tecer reflexões sobre esse tema no contexto da apicultura. Os dados foram coletados no período de junho de 2016, utilizando abordagem quantitativa e descritiva, através de livros e seguintes bases de dados: SciVerse Scopus, Scientific Electronic Library Online (SciELO) e a Ferramenta de Pesquisa Acadêmica (Scholar Google). A busca foi desenvolvida utilizando-se o descritor de assunto, morfologia, reprodução e genética de <em>Apis mellifera</em>, referida em periódicos sobre o tema. Observa-se um aumento gradativo de informações coletadas pela temática dos descritores mencionados. Finalmente, as informações aqui registradas poderão servir como base para novos estudos.</p><p align="center"><strong><em>Biology of bees Apis mellifera: A literature review</em></strong><strong><em></em></strong></p><p>Honey bees are very important for biological diversity of ecosystems, the most used in the service of pollination of plants, because of their characteristics and adaptation of floral structures. The aim of this study was to review the literature on studies related to the biology of bees, aiming to weave reflections on this issue in the context of beekeeping.

The use of legumes as fertilizer haqs been a viable option for the farmers who work in the production of medicinal plants with agroecological management. In this sense, the objective was to evaluate the production of mint under planting densities of mung bean in loam argisol yellow red latosol. The experiment was conducted at the Rafael Fernandes Experimental Farm, in the Alagoinha district, rural area of Mossoró, RN, Brazil, from August 2016 to March 2017. The experimental design was randomized complete blocks with the treatments arranged in 4 x 2 factorial scheme with three replicates. The first factor consisted of sowing densities (50; 100; 150 and 200 plants m-2) and the second factor was management systems such as incorporation and permanence (covered) of mung bean biomass on the soil surface. The cultivar "Mentha piperita" was used for the mint crop. The evaluated characteristics were the following: biomass height, green mass production, number of bunches, dry mass production, oil content and oil production of mint. The sowing density of 150 plants m-2 of mung bean provided production and number of mint bunches of 2.63 kg m-2 and 26.3 units m-2, respectively. For the forms of biomass management (incorporated and covered), no statistical difference was observed for the characteristics of the production of green mass, number of bunches, content and oil production of mint. The use of mung bean as a green manure for mint production is feasible to be used by farmers in northeastern Brazil.
Using goat manure may substantially increase cowpea bean productivity. This study evaluated the yield of ‘pingo de ouro’ cowpea bean under different sowing densities and goat doses in the region of Mossoró, Brazil. The experiment was conducted from October to December 2016 at the Experimental Farm Rafael Fernandes, Mossoró-RN, Brazil. Treatments arranged in two-way factorial with four goat manure doses (0.0, 0.5, 1 and 2 kg m-1), and two sowing densities of bean (75,000 and 37,500 plants ha-1), with three replicates. The experiment was performed in complete randomized blocks design. We evaluated the number and length of pods per plant, number of seed per pod, weight of 100 dry grains and dry grain yield. Higher grain yield occurred using 2.0 kg m-1 of goat manure (1,162.4 kg ha-1 or 234 kg 2,000 m-2) and 75,000 plants ha-1 (693.4 kg ha-1 or 138.6 kg 2,000 m-2). High sowing density in combination with goat manure is an affective.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
