dc.description.abstract | The expansion of the agricultural frontier is one of the main causes of biodiversity loss and detriment of ecosystem services essential for agricultural production, including biological pest control. In this work, the relationship between the loss of native forest cover, diversity of arthropods and weeds in crops and its relationship with herbivory and crop production was examined, using twelve traditional corn crop fields in Topaipí (Cundinamarca) during the second growing season in 2011. In the studied cornfields pest control was provided by native predators and parasitoids, which in turn depended upon the maintenance of the diversity of weeds within crops. Forest cover promoted complexity of networks of plant-arthropod in this system, in which the richness of predators was associated with increased production of crops. Therefore, the conservation of forests in traditional crop systems is essential for biological control, production and biodiversity conservation. |
dc.description.abstract | La expansión de la frontera agrícola es una de las principales causas de pérdida de la biodiversidad y detrimento de las funciones ecosistémicas esenciales para la producción agrícola, entre ellas el control biológico de plagas. En este trabajo, se evaluaron las relaciones entre la pérdida de cobertura de los bosques nativos, la diversidad de arvenses y artrópodos dentro de los cultivos y su relación con la herbivoría y la producción en doce cultivos tradicionales de maíz en Topaipí (Cundinamarca), durante la segunda temporada de siembra de 2011. En los cultivos estudiados el control biológico de plagas fue proporcionado por predadores y parasitoides nativos, y estos a su vez dependieron del mantenimiento de la diversidad de arvenses dentro de los cultivos. La cobertura de bosques promovió la complejidad de las redes de interacción plantas-artrópodos en este sistema, en los que la riqueza de depredadores se asoció con una mayor producción de los cultivos. Por lo anterior, la conservación de los bosques en sistemas de cultivos tradicionales es esencial para el control biológico, la producción y la conservación de la biodiversidad.
