FONTE, Leydi; MILERA, Milagros; DEMEDIO, J    BLANCO, D. Selectividad de pecoreo de la abeja sin aguijón Melipona beecheii Bennett en la EEPF "Indio Hatuey", Matanzas. []. , 35, 3, pp. 333-342. ISSN 0864-0394.

^les^aEl trabajo se realizó en la EEPF "Indio Hatuey", con el objetivo de determinar la selectividad de pecoreo de la abeja sin aguijón (Melipona beecheii Bennett), mediante el análisis palinológico de muestras de miel y polen. Previamente se realizó un inventario florístico del área, alrededor del emplazamiento del meliponario, basado en el radio de vuelo de las abejas. En las silvopasturas se utilizó el método de la escalera, y en el caso de los cercados vivos se contaron los árboles cada 10 m y se reflejaron en el croquis del área muestreada. En las arboledas y los traspatios de las viviendas se contaron y clasificaron todos los árboles existentes, y en el estrato herbáceo se aplicó el método de los pasos. En ambos tipos de muestra predominaron los granos de polen de guayaba (Psidium guajava) y almácigo (Bursera simaruba), seguidos por los de dormidera (Mimosa pudica), sensitiva (Mimosa pigra), y naranjo y limonero (Citrus spp.). Se concluye que las abejas meliponas presentaron una marcada selectividad de pecoreo por las floraciones del almácigo y la guayaba, y que la Estación cuenta con el potencial melífero suficiente para que puedan desarrollarse favorablemente, sobre una base alimentaria sustentable.^len^aThe work was conducted at the EEPF "Indio Hatuey" to determine the foraging selectivity of stingless bees (Melipona beecheii Bennett) through the analysis of honey and pollen samples. A floristic inventory of the area had been previously made around the apiary location, taking into consideration the bees' flight radius. The stair method was used in the silvopastures, and in the case of the living fences the trees were counted every 10 meters and this was shown in the sketch of the sampled area. In the groves and yards all trees where counted and classified, and in the herbaceous stratum the step method was applied. The pollen grains of guava (Psidium guajava) and mastic tree (Bursera simaruba) predominated in both kinds of samples, followed by the pollen grains of touch-me-not (Mimosa pudica), mimosa (Mimosa pigra), orange and lemon tree (Citrus ssp.).The stingless bees were concluded to show marked foraging selectivity for the guava and mastic tree flowers, and that the Station has the sufficient melliferous potential for them to develop favorably, on a sustainable feeding basis.
