Cuban stingless bee livestock exhibit specialized floral resource use: a palynological study on honey samples from Matanzas and Mayabeque provinces

The knowledge of the different plant species that make up the feeding diet of animals is highly important to develop more efficient strategies. This research aimed to characterize the food potential available for the Cuban stingless bee livestock of the Matanzas and Mayabeque provinces. Palynological analysis was done using 60 g of pollen from sealed pots and 80 mL of honey from the ten randomly selected beehives (five in each province). The results showed that in the honey collected in Matanzas province, the most represented family was Amaranthaceae, followed by Myrtaceae and Fabaceae. Meanwhile, for Mayabeque, the most represented ones were the families Fabaceae and Myrtaceae. Regarding the stingless bee pollen of Matanzas provenance, the family Fabaceae prevailed, followed by Burseraceae and Myrtaceae. The pollen corresponding to Mayabeque coincided in showing Fabaceae as the most representative. In addition, pollen grains of small size (from 10 to 25 µm) were collected, with a marked representation of the pollen type of Mimosa pudica in the Mayabeque honey. It was concluded that the Cuban stingless bee livestock of the Matanzas and Mayabeque provinces had a specialist feeding behavior because a low number of plant taxa made up its diet

Gliricidia Sepium: Leguminosa forrajera útil como habitáculo de Melipona Beecheii en sistemas agrarios

Al partir de la experiencia de un pequeño agricultor de la localidad de Jagüey Grande, se procedió a la localización de nueve colmenas de Melipona beecheii, en un radio aproximado de 1,5 km. Posteriormente, se identificó el árbol anfitrión y la ubicación. Cuatro de las nueve colonias fueron trasladadas a la Estación Experimental de Pastos y Forrajes “Indio Hatuey”, en el municipio de Perico, provincia de Matanzas, Cuba; después de la apertura de los troncos con una motosierra, se llevó a cabo la caracterización de las colmenas que contenían. Por último, se realizó la división y traslado hacia siete cajas del sistema Nogueira-Neto, ocho de las colonias originales se localizaron en postes de piñón florido y la restante en aguacate. Las dimensiones de los troncos en que se hallaron (65-225 cm x 30-53 cm), evidencian la edad avanzada de estos
