ABSTRACT.
For more than 60 years, sporadic cases of massive summer honey bee larvae mortality in colonies located near freshwater systems with abundant riparian vegetation have been reported in Uruguay. This odd phenomenon, known as ?River disease? by beekeepers, can lead to colony death by depopulation. The aim of this study was to detect the causes of larvae death. Different experiments and analyses were performed using affected apiaries located between two important water courses. 1 day old larvae were the most susceptible and substances that killed the larvae were present in the nectar but not in the pollen. A palynological analysis of nectar samples showed that bees collect this resource from commonly pollinated floral species in the country. However, abundant fungi spores and conidia were found, which indicates that the bees also collected honeydews. In the riparian vegetation, bees were observed collecting the secretions of the planthopper Epormenis cestri on Sebastiania schottiana trees. It was found that the mortality period of larvae overlaps with the presence of E. cestri. Larvae maintained in the laboratory were fed (i) nectar from healthy colonies, (ii) nectar from affected colonies, and (iii) secretions of E. cestri. The mortality of the larvae that received nectar from colonies affected with River disease and secretions of E. cestri was higher than the mortality of those receiving nectar from healthy colonies. This represents the first report of planthopper honeydew causing mass larval mortality in honey bees. © 2018 Invernizzi et al.

En la región noreste existe una importante área de suelos arenosos (luvisoles y acrisoles), con bajo contenido de materia orgánica, fuerte acidez natural y presencia de aluminio intercambiable. Debido a sus características físico-químicas y la fuerte topografía imperante, son muy propensos a degradarse y/o erosionarse cuando sobre ellos se realizan sucesivos cultivos sin las adecuadas medidas de manejo. Es principalmente sobre ellos que se realiza la actividad hortícola de la región. En Tacuarembó el cultivo hortícola más importante es la papa. Generalmente se produce bajo régimen de medianería y se realizan dos plantaciones anuales sobre
campo natural o rastrojos empastados o recuperados, luego de los cuales se abandonan las chacras y se buscan nuevas tierras para iniciar un nuevo ciclo. Debido a los cambios en la tenencia de la tierra en la región y al fuerte impacto de la forestación, ha disminuido la disponibilidad de campo natural o regenerado para mantener este sistema de producción. Buscando alternativas a la situación planteada, entre el año 1996 y 2000, se instaló una serie de experimentos en la Unidad Experimental de La Magnolia con el objetivo de evaluar la evolución de la productividad del cultivo de papa en el tiempo en función de la intensidad de uso del suelo y de la incorporación de materia orgánica al mismo proveniente de rastrojos de cultivos y/o pasturas. |
