La división artificial de colonias de abejas S. mexicana es una actividad en la meliponicultura, en donde se reporta la mayor pérdida de colonias. Entre las diversas causas de dicha mortalidad destaca la dificultad de la nueva colonia por mantener la termorregulación de su nido, ya que tradicionalmente se utilizan vasijas de barro en cuyo caso es más difícil mantener una temperatura estable. El objetivo de este estudio fue analizar las interacciones entre modelo de caja, su material de construcción y el recubrimiento de los panales de cría; en la temperatura interna del nido y el desarrollo de colonias obtenidas por división artificial. Se cuantificó el desarrollo de éstas mediante su ganancia de peso final e inicial, y el número de celdas construidas, actividad de la colonia y capacidad del diseño en mantener la temperatura interna del nido. Los resultados muestran que los mejores rangos de temperatura interna se lograron en nidos transferidos a cajas racionales modelo Portugal-Araujo (P<0.05) y Ailton-Fontana (P<0.05) cuyos diseños originales fueron modificados al incluir láminas de poliestireno expandible. Además, la temperatura y desarrollo de la colonia se vio favorecida cuando los panales recién transferidos fueron recubiertos con un molde elaborado de cera de abeja Apis mellifera L. La interacción positiva entre estos factores permitió proporcionar un rango de temperatura óptimo (27.9 a 31.0 °C) para el desarrollo de las colonias, las cuales obtuvieron ganancia de peso entre 0.149 a 0.289 kg y del número de celdas construidas entre 3,511 a 4,956 celdas de cría.

Scaptotrigona Mexicana

In this paper we show the results of investigating the presence of organochlorine pesticides in honey and pollen samples from managed colonies of the honey bee, Apis mellifera L. and of the stingless bee Scaptotrigona Mexicana Gu&eacute;rin. We found that 88.44% and 93.33% of honey samples, and 22.22% and 100% of pollen samples of S. mexicana and A. mellifera, respectively, resulted positive to at least one organochlorine. The most abundant pesticides were DDE, DDT, Endrin and heptaclor. Despite the low foraging range of S. mexicana the number of pesticides detected in the honey samples was similar to that of A. mellifera. Paradoxically we a found a small number of organochlorines in pollen samples of S. mexicana, perhaps indicating a rapid turnover of this material as compared to A. mellifera.

Toxicity of the Trichoderma harzianum-based fungicide Bioben® was evaluated in three species of bees and Anastrepha ludens, in the Soconusco region, Chiapas, Mexico, under laboratory conditions. Mortality in Scaptotrigona mexicana and Apis mellifera were slightly higher in the exposed groups than in control groups, contrary to Melipona beecheii and A. ludens.

In addition to the compound eyes, honeybees have three dorsal ocelli on the vertex of the head. Each ocellus has about 800 elongated photoreceptor cells. They are paired and the distal segment of each pair bears densely packed microvilli forming together a platelike fused rhabdom. Beneath a common cuticular lens a single layer of corneagenous cells is present.Ultrastructural studies were made of the retina of praepupae, different pupal stages and adult worker bees by thin sections and freeze-etch preparations. In praepupae the ocellar anlage consists of a conical group of epidermal cells that differentiate to photoreceptor cells, glial cells and corneagenous cells. Some photoreceptor cells are already paired and show disarrayed microvilli with circularly ordered filaments inside. In ocelli of 2-day-old pupae, when a retinogenous and a lentinogenous cell layer can be clearly distinguished, cell membranes of the distal part of two photoreceptor cells begin to interdigitate with each other and so start to form the definitive microvilli. At the beginning the microvilli often occupy the whole width of the developing rhabdom (Fig. 1).
