Diversifying agricultural landscapes may mitigate biodiversity declines and improve pest management. Yet landscapes are rarely managed to suppress pests, in part because researchers seldom measure key variables related to pest outbreaks and insecticides that drive management decisions. We used a 13‐year government database to analyse landscape effects on European grapevine moth (Lobesia botrana) outbreaks and insecticides across c. 400 Spanish vineyards. At harvest, we found pest outbreaks increased four‐fold in simplified, vineyard‐dominated landscapes compared to complex landscapes in which vineyards are surrounded by semi‐natural habitats. Similarly, insecticide applications doubled in vineyard‐dominated landscapes but declined in vineyards surrounded by shrubland. Importantly, pest population stochasticity would have masked these large effects if numbers of study sites and years were reduced to typical levels in landscape pest‐control studies. Our results suggest increasing landscape complexity may mitigate pest populations and insecticide applications. Habitat conservation represents an economically and environmentally sound approach for achieving sustainable grape production.

El presente artículo es el resultado de una investigación de campo, descriptiva, transversal y cuantitativa, que incluye un análisis descriptivo cuantitativo, en el cual se determina que no existe por parte de las autoridades de los Gobiernos Autónomos Descentralizados Parroquiales una socialización adecuada y continua de los planes territoriales que se deben aplicar en la cabecera parroquial y en cada uno de los recintos aledaños que pertenecen a la Parroquia Roberto Astudillo, del Cantón Milagro, provincia del Guayas, Ecuador. Además se analizó la existencia de sistemas de control en cuanto al crecimiento socio económico, sostenibilidad ambiental en relación con la planificación territorial. Se concluye que dentro de la planificación si existen objetivos planteados en cada una de las áreas y que por falta de socialización los habitantes desconocen, además se estableció que no existen sistemas de control que les permita determinar cuál fue el impacto, relacionando el crecimiento antes de la aplicación del plan regional. AbstractThis article is the result of field research, descriptive, transversal and quantitative, which includes an analysis, which determined that there is not continuous socialization of territorial plans to be applied to the Parish Hall and each of the neighboring enclosures belonging to the Parish Roberto Astudillo, Canton Milagro, Guayas Province, Ecuadorfrom the authorities of the Autonomous Governments Decentralized. It concluded that in planning if their objectives in each of the areas that are unknown by its inhabitants due to lack of socialization. Furthermore, it was established that there were no monitoring systems that allow them to determine what the impact relating the growth before the implementation of the regional plan.
