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

Abstract

ABSTRACT:The 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.

Homeopatia Na Agricultura

“…A coloração da caixa pode influenciar na temperatura interna do ninho. Cores claras, por refletirem mais a radiação solar que entra, podem proporcionar um ambiente térmico mais apropriado para o desenvolvimento da prole (SOUZA et al, 2016). Um material que atende a esta demanda de coloração e pode ser usado na fabricação de caixas é o isopor ® .…”

Desenvolvimento de abelhas melíferas em colmeias com diferentes cores e materiais de cobertura no semiárido brasileiro

“…O material utilizado para cobertura das colmeias também são um diferencial em se tratando de conforto térmico e desenvolvimento das colônias (Crane & Graham, 1985;Dupleix et al, 2020). O uso de placas de gesso na cobertura de colmeias, tem se tornado uma prática cada vez mais usual entre os apicultores de regiões de clima semiárido, onde, na ausência de sombreamento natural, o uso de placas de gesso e a pintura das colmeias com cores claras, proporcionariam um ambiente interno mais favorável para as abelhas (Souza et al, 2015).…”
