Internal ambience of beehives Apis mellifera with different colors and roofing materials in the sub middle of the São Francisco Valley

ABSTRACTThe current study aimed to evaluate the influence of three colors and two types of roofing materials under the internal temperature of bee colonies Apis mellifera. The experiment was conducted at the Agricultural Sciences Campus at the Federal University of Sao Francisco Valley located in Petrolina-PE, in November and December 2013, using 24 colonies housed in Langstroth hives. The experiment was a completely randomized factorial design (3x2) with three colors of box (blue, white, and traditional) and two types of cover (with and without the use of plaster) with six treatments and four replications. The internal temperature dates of the colonies were hourly recorded, during 24 hours, and surface temperatures were hourly recorded between 08h00 and 17h00. The highest values for surface and internal temperature were registered in the blue painted boxes without the use of plasterboard, and the blue painted boxes covered with plasterboard respectively. However, the lowest values ​​were found in the white painted hives and hives that have not received the plasterboard. It is recommended to paint boxes with bright colors, and the use of plasterboard had no effect in reducing the internal temperature.

Industrial apiculture in the Jordan valley during Biblical times with Anatolian honeybees

Although texts and wall paintings suggest that bees were kept in the Ancient Near East for the production of precious wax and honey, archaeological evidence for beekeeping has never been found. The Biblical term ""honey"" commonly was interpreted as the sweet product of fruits, such as dates and figs. The recent discovery of unfired clay cylinders similar to traditional hives still used in the Near East at the site of Tel Rehov in the Jordan valley in northern Israel suggests that a large-scale apiary was located inside the town, dating to the 10th-early 9th centuries B.C.E. This paper reports the discovery of remains of honeybee workers, drones, pupae, and larvae inside these hives. The exceptional preservation of these remains provides unequivocal identification of the clay cylinders as the most ancient beehives yet found. Morphometric analyses indicate that these bees differ from the local subspecies Apis mellifera syriaca and from all subspecies other than A. m. anatoliaca, which presently resides in parts of Turkey. This finding suggests either that the Western honeybee subspecies distribution has undergone rapid change during the last 3,000 years or that the ancient inhabitants of Tel Rehov imported bees superior to the local bees in terms of their milder temper and improved honey yield.

A expansão da agroindústria do mel no Rio Grande do Norte

The beekeeping activity has become in all regions of Brazil until the early 80s and from 2000 to beekeeping Northeast also has developed, becoming a major oil producing honey. The Rio Grande do Norte following these developments happened to occupy fourth place in the ranking of export of honey between the states of the Northeast in 2007. Therefore, the aim of this paper is to present a macro radiography of recent developments in the production chain of honey in the state of Rio Grande do Norte, organizing and discussing the information, collected in the period 2004 to 2007, as well as evaluating the prospect of the honey industry in order to provide a diagnosis able to identify opportunities and enhance the marketing of their products. From the methodological point of view, this study can be classified as a research study exploratory and descriptive by using questionnaires. The group of several studies has been productivity, production and market. Search results indicated the growth of industry in 4 years of activity by the number of beehives full and populated, infrastructure, production and marketing of the state. It can be said that beekeeping of Rio Grande do Norte, despite its potential for developing the activity comes in a different way when compared to other activities, because the actors who play to start the activity through training and to play with it in a professional manner, in addition to support staff who work in the industry

Produtos naturais para o controle do ácaro Varroa destructor em abelhas africanizadas

O objetivo deste trabalho foi avaliar os efeitos do ácido oxálico e de óleos essenciais de plantas no controle da infestação pelo ácaro Varroa destructor em colônias de Apis mellifera africanizadas. O experimento foi realizado em delineamento inteiramente casualizado, em 30 colônias, com seis tratamentos e cinco repetições. As colmeias foram tratadas com óleos essenciais de arruda (Ruta graveolens), eucalipto (Eucalyptus spp.) e hortelã (Mentha piperita), além de timol, ácido oxálico e do tratamento controle sem aplicação de produtos. Foram avaliadas a mortalidade de varroas e as taxas de mortalidade de crias e de infestação de varroas em crias e em abelhas adultas, antes e depois da aplicação de cada produto. O ácido oxálico e os óleos de arruda, timol, eucalipto e de hortelã reduziram a mortalidade de crias parasitadas pelo ácaro em 92,1, 83,3, 81,7, 86,4 e 81,3%, respectivamente. O tratamento com ácido oxálico reduziu em 87,4% a infestação de varroas em abelhas adultas. O uso desses produtos é eficiente na redução da mortalidade de crias de A. mellifera parasitadas por V. destructor.

TELA EXCLUIDORA DE RAINHA NA PRODUÇÃO DE MEL E NA LONGEVIDADE DAS OPERÁRIAS em COLMEIAS DE Apis mellifera

Este trabalho tem como objetivos verificar as áreas de cria e alimento e a longevidade de operárias em colmeias de Apis mellifera, em apicultura fixa (mata) e migratória (laranja e eucalipto), sem (T1) e com (T2) tela excluidora de rainha. Foram utilizadas colmeias modelo Langstroth, com sobrecaixa. Na apicultura fixa, estas colmeias foram analisadas durante 476 dias e mapeadas a cada 30 a 45 dias para obtenção das áreas de cria e alimento. Na migratória, as colmeias foram analisadas antes e após a florada. Foi estudada também a longevidade das operárias, nos dois tratamentos. Os dados mostraram que em fluxo baixo de néctar (apicultura fixa, em mata), o uso de tela excluidora apresentou maior eficiência na separação do mel das crias. Entretanto, quando o fluxo de néctar foi alto (floradas de laranja e eucalipto), a tela excluidora não foi eficiente, pois as abelhas rapidamente preencheram os favos disponíveis no ninho inferior, misturando-o com cria. Observou-se também redução na longevidade das operárias das colmeias com tela excluidora, em dois dos três testes realizados. Este trabalho, desenvolvido em três locais diferentes, com plantas apícolas distintas evidenciou também a variabilidade e a grande influência ambiental no desenvolvimento das colônias de Apis mellifera.

Contribuição ao protocolo de controle de qualidade da própolis e de seus extratos

A quality control protocol for the analysis of propolis and its extracts is proposed in the present work. Propolis of Apis mellifera L. bees collected in beehives of an apiary located in the northwest of the Paraná State was triturated and submitted to the following analysis: particles medium size determination, loss of dry, ashes drift, waxes drift, drift of extractive (in water and in ethanol) and total flavonoids drift determination. Propolis ethanolic extracts (96 °GL) at 10% (w/w) and at 30% (w/w) were prepared and submitted to the determination of the pH, relative density, dry residue, alcoholic drift and total flavonoids drift determination. Propolis was analyzed, through High Performance Liquid Cromatography (HPLC). Comparing the obtained results with other works, it was observed that is possible to establish the intervals of values for parameters in order to evaluate the quality of a propolis sample and its extracts.

Desenvolvimento de núcleos de Apis mellifera alimentados com suplemento aminoácido vitamínico, Promotor L

The development in the area of creates was studied of 14 nuclei with four mass off cells from the division of nine beehives of africanized Apis mellifera honeybees, distributed in two treatments: TPL - nuclei fed with inverted sugar + 3.5ml of the vitaminic amino acid supplement (Promotor L® ), composition for six nuclei and TAI - nuclei fed with composed inverted sugar for eight nuclei. The nuclei had been fed weekly in individual feeder's type tray, and the evaluations carried through in four periods, totalizing 74 days. The treatments had not presented significant difference, being that, number the TPL presented area of creates inferior to TAI (233.63 versus. 273.02cm 2, respectively). How much to the periods the four was superior (P<0.05) to the first and as second, being that the third did not present significant difference (P<0.05) in relation to the others. The use of the TAI was economically more favorable in relation to the TPL in R$0.21 in relation to the cost for production of 1kg of food.
