Se utilizaron cuatro bastidores de colmenas tipo Jumbo (45 x 28 cm) dentro de cámaras de cría con tres tamaños internos (52.2, 42.3 y 23.9 L), que contenían el mismo número de abejas melíferas. De manera simultánea se registraron las temperaturas dentro de las colmenas para determinar si la temperatura de la cámara de cría variaba con el volumen. La colmena de mayor tamaño, que corresponde al tipo Jumbo y la más utilizada en el altiplano central mexicano, presentó los valores más bajos de fortaleza y reservas de alimento, así como la menor temperatura interna. Estos resultados muestran que la utilización de colmenas tipo Jumbo puede repercutir en una disminución de la productividad de miel y polen para los apicultores del altiplano central de México, por lo que es necesario implementar alguna práctica o mecanismo que permita mantener las colonias de abejas fuertes para la cosecha de primavera.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract This study aimed to analyze the effect of the internal size on the strength (brood area) and productivity (honey and pollen areas) of the honeybee hives during the winter season in a semiarid region of the central Mexican plateau. Four Jumbo hive frames (45 x 28 cm) were used inside brood chambers with three internal sizes (52.2, 42.3, and 23.9 L), each chamber contained the same number of honeybees. Simultaneously, it was recorded the temperature inside the hives to determine if the brood chamber temperatures varied with the volume. The Jumbo hive, which is the largest hive, is the most used in the central Mexican plateau and showed the lowest strength and productivity values, as well as the lowest internal temperature. These results show that Jumbo hives can decrease the honey and pollen productivity for the central Mexican plateau beekeepers, which is why it is necessary to implement a practice or mechanism that allows maintaining strong beehives for the spring harvest.]]></p></abstract>
