Summary

Recent declines in honey bee populations have created deficiencies in agricultural pollination, and motivated the search for alternatives to traditional honey bee colonies. Mini-nucleus colonies (mininucs), small honey bee hives containing a few hundred workers, are easier and cheaper to set up, maintain and transport than regular sized colonies. We tested whether mininucs can provide effective agricultural pollination in enclosures. We compared the efficiency of mininucs vs. regular Langstroth colonies in pollinating honeydew melons in tunnel net-houses. Flower visit frequencies were higher in net-houses with regular hives than in those with mininucs, but fruit weight and density were not affected by colony type. We suggest that mininucs can effectively pollinate melons in enclosed spaces, and that their ease of handling and non-aggressive behaviour further increases their appeal for agricultural pollination.

Los recientes descensos de poblaciones de abejas has creado deficiencias en la polinización agrícola y han provocado la búsqueda de alternativas a las colonias tradicionales de abejas. Las colmenas mini-núcleos (mininuc) son pequeñas colmenas de abejas de unas cientos de abejas obreras, más fáciles y baratas de establecer, mantener y transportar que las colmenas de tamaño normal. Hemos contrastado si los mininucs pueden producir polinización agrícola efectiva en invernaderos. Para ello hemos comparado la eficiencia de los mininucs frente a colmenas tradicionales Langstroth en la polinización de melones dulces de pulpa verde en invernaderos con forma de túnel. La frecuencia de flores visitadas fue mayor en invernaderos con colmenas tradicionales que en aquellos con minicus, pero el peso y la densidad del fruto no se vieron afectados por el tipo de colmena. Sugerimos que los mininucs pueden polinizar melones de forma efectiva en invernaderos, y que la facilidad de manejo y comportamiento no agresivo aumenta su atractivo para la polinización agrícola.
