Abstract (portuguese)
Este experimento teve como objetivos verificar a regulação da temperatura interna da colônia de abelhas africanizadas (AFR) comparada com abelhas híbridas de caucasianas (CAU), italianas (ITA) e cárnicas (CAR), no decorrer de um ano e, em colméias de tamanhos diferentes, em região com clima subtropical. Na primeira etapa, a temperatura interna do momento não apresentou diferença significativa (P>0,05) entre os híbridos estudados e foi de 33,7 ± 1,5°C, para as AFR; 33,5 ± 1,4°C, para as CAU; 33,7 ± 1,5°C, para as ITA e 33,8 ± 1,4°C, para as CAR. Na segunda etapa, a temperatura máxima (36,1 ± 2,3°C) foi diferente estatisticamente (P>0,05) da mínima (27,6 ± 5,3°C). Não houve diferença (P>0,05), na temperatura interna média, entre núcleo (31,7 ± 6,3°C) e ninho (32,1 ± 5,3°C), medida das 14 às 16 horas.
Abstract (english)
This experiment was carried out to study the internal temperature regulation of a colony of Africanized honey bees (AFR), compared with hybrid Caucasian (CAU), Italian (ITA), and Carniolan (CAR) bees, during the period of one year and different size hives located in a sub-tropical region. The instant internal temperature, 33.7 ± 1.5° C for the AFR, 33.5 ± 1.4° C for the CAU, 33.7 ± 1.5° C for the ITA and 33.8 ± 1.4° C for the CAR, did not show any significant difference (P>0.05). The maximum temperature (36.1 ± 2.3° C) was statistically different (P<0.05) from the minimum (27.6 ± 5.3° C). There was no difference (P>0.05) in the mean internal temperature, between the nucleus (31.7 ± 6.3° C) and the brood nest (32.1 ± 5.3° C) measured between two and four o'clock in the afternoon.
