Resumen
[ES] Las prácticas agrícolas en el olivar han evolucionado con el transcurso del tiempo, pasando por distintos periodos en los que el control de las plagas que afectan a este cultivo ha sido una de las principales premisas de su gestión. Esta evolución ha generado distintas doctrinas de manejo del olivar, como las que se llevan a cabo en el olivar convencional, el olivar convencional con cubierta vegetal o el olivar ecológico. El objetivo de este trabajo es relacionar la abundancia de diferentes enemigosnaturalescon las figuras de manejo descritas anteriormente, y poder determinar que posibles factores condicionan su presencia y abundancia en él olivar. Como objetivo secundario, se pretende aportar datos para la puesta a punto de los métodos de muestreo y monitorización de enemigos naturales.
Para la ejecución del estudio se seleccionaron 3 olivares localizados en la provincia de Jaén ajustados a los distintos regímenes descritos, y que fueron monitorizados mediante trampeo cromático.

For the execution of the study, three olive groves located in the province of Jaén were selected, adjusted to the different regimes described, and monitored by means of chromatic trapping.
