Efficiency of pollination by orphan colonies of Bombus atratus (Hymenoptera: Apidae) in strawberry (Fragaria x ananassa) in greenhouse ; Eficiencia de polinización de colonias huérfanas del abejorro nativo Bombus atratus (Hymenoptera: Apidae) en dos cultivares de fresa (Fragaria x ananassa) sembrados bajo cubierta en la sabana de Bogotá
In Colombia the strawberry has become a crop of economic interest due to the growing demand in the foreign market in the last decade. Most plantations are open fields and do not use pollination strategies to improve the production quality. Pollination with bumblebees improves the quality of the fruits, although these are produced by spontaneous pollination. The native species Bombus atratus has been recognized as an efficient pollinator of Colombian horticultural crops under greenhouse. The present study evaluated the pollination efficiency of two orphan colonies in the quality of the fruits o... Mehr ...

In Colombia the strawberry has become a crop of economic interest due to the growing demand in the foreign market in the last decade. Most plantations are open fields and do not use pollination strategies to improve the production quality. Pollination with bumblebees improves the quality of the fruits, although these are produced by spontaneous pollination. The native species Bombus atratus has been recognized as an efficient pollinator of Colombian horticultural crops under greenhouse. The present study evaluated the pollination efficiency of two orphan colonies in the quality of the fruits of the "Camino real" and "Ventana" cultivars planted under a greenhouse in Cajicá-Colombia. The buttons were excluded to obtain the fruits produced spontaneously and to be compared with the fruits coming from the visit of workers of B. atratus. It was found that the visit of the workers improved fruit quality in the features: caliber (35 % and 31 %), length (28 % and 19 %), fresh weight (103 % and 90 %), dry weight 126 % and 145 %) and number of seeds (55 % and 81 %) for the cultivar "Camino Real" and "Ventana" respectively. From the observations made, it was determined that the floral resource used by the workers of B. atratus was the nectar and recommendations are done about on its use in this crop. ; En Colombia la fresa se ha convertido en un cultivo de interés económico debido a la creciente demanda en el mercado extranjero en la última década. La mayoría de plantaciones son a campo abierto y no usan esquemas de polinización para mejorar la calidad de producción. La polinización con abejorros mejora la calidad de los frutos, aunque estos se producen mediante polinización espontánea. La especie nativa Bombus atratus ha sido reconocida como un polinizador eficiente de cultivos hortofrutícolas colombianos bajo invernadero. El presente estudio evaluó la eficiencia de polinización de dos colonias huérfanas en la calidad de los frutos de las variedades camino real y ventana sembrados bajo invernadero en Cajicá-Colombia.
