Resumo: The expanded vermiculite is a light-weighted and cheap product that, for its thermal resistance, has become a valuable insulating material, oftently used in engineering. Brazilian Apiculture is currently facing some obstacles to produce wooden hives. Regarding the similar physical properties within the wood, the hives made of cement-vermiculite mortar (CVM) have been tested in order to find out if it shows also similar biological responses to the wooden hives. This study took place in a tropical region ((22?45?28"S, 43?41?05"W), during eight months. Standard Langstroth hives (n=20) were built, and used in an apiary containing Africanized honeybees colonies from equal strength (one super) and queen line. The CVM boxes and colonies were compared with control one (wooden made) in a completely randomized design, with two factors (beginning and end of the study, with and without bees) and 5 repetitions/treatment, which were used in order to test the colony performance patterns: thermal control, flight activity, area of wax comb production and storage of food, weight of the super, honey collected and its chemical analysis. The standard CVM hive (2 supers) weights about 21.66 kg and its cost requirement (US$15.19) was 28.50% cheaper than the wooden hives cost. There were no significant differences between the hives performance. The honey quality sampled in both types of material followed the pattern of the schedule chemical analysis. Although the experiment time was restricted, the results allow us to recommend this new material (CVM) to small or poor beekeepers, to regions that need wood extraction prevention and to tropical regions. For it cannot be transported, the CVM hives must not be used for migratory activity. Hives made of cement-vermiculite mortar have been studied for two years now, and more time is needed to further observations.

Nesta pesquisa, tendo como proposta a constru??o de caixas de abelhas com argamassa cimento-vermiculita (ACV), testou-se se este material apresenta respostas f?sicas e biol?gicas semelhantes ?s caixas constru?das de madeira. Esse estudo foi realizado em uma regi?o tropical (22?45?28"S, 43?41?05"W) durante oito meses. As caixas, modelo Langstroth, foram constru?das, instaladas e povoadas em um api?rio de col?nias de abelhas Africanizadas, com a mesma popula??o e parentesco da rainha. Acompanhou-se a temperatura interna, avaliou-se a condutividade t?rmica e a perda evaporativa das caixas de madeira e de ACV, n?o povoadas. Quando em col?nias, verificou-se seus padr?es de desempenho referentes ao controle t?rmico, da atividade de v?o, da ?rea de produ??o de favos e armazenamento de alimento, do peso da melgueira, do mel coletado e da sua qualidade qu?mica. As caixas e col?nias de ACV foram comparadas ?s de controle, de madeira, em um delineamento inteiramente casualizado, com dois n?veis de tratamento (tipo de material, in?cio e fim do estudo) e cinco repeti??es por tratamento, atrav?s da an?lise de vari?ncia. O peso da colm?ia padr?o ACV foi aproximadamente o dobro da de madeira e seu custo de US$15,19) foi 28,50% mais baixo que o da colm?ia de madeira. A temperatura m?dia interna das caixas e colm?ias de madeira e vermiculita foram semelhantes. Na caixa de ACV houve maior absor??o e perda mais r?pida de ?gua do que na de madeira. Apesar do controle t?rmico das col?nias de ACV, verificou-se que, eventualmente o intervalo da temperatura interna ultrapassou a faixa ?tima, o que pode ter ocasionado a redu??o da atividade de v?o, cuja diferen?a com a colm?ia de madeira foi significativa. A ?rea de forma??o de favos, de armazenamento de alimento e o peso do mel coletado n?o apresentaram diferen?as significativas, mas sofreram grande varia??o. A qualidade do mel amostrados nas colm?ias de ACV e madeira apresentaram-se dentro do padr?o rotineiro de an?lise qu?mica. Considerando-se que a caixa de ACV representa um modelo de constru??o artesanal, de baixo custo e caracter?sticas semelhantes ? caixa de madeira, sua utiliza??o torna-se mais uma alternativa vi?vel para o meio ap?cola, exceto para a atividade migrat?ria.Submitted by Jorge Silva (jorgelmsilva@ufrrj.br) on 2017-09-19T18:59:45Z No. of bitstreams: 1 2003 - Rodolfo Gon?alves Cidreira.pdf: 722635 bytes, checksum: 63e736c0ca9789c17ca28fc8da29134d (MD5)Made available in DSpace on 2017-09-19T18:59:45Z (GMT).
