Rasgos funcionales como mediadores de la respuesta de enemigos naturales de plagas al manejo en sistemas frutícolas

Abstract

A través del análisis de rasgos funcionales, se examinó la influencia de prácticas de manejo (control de malezas y tipo de riego) en la abundancia y diversidad de enemigos naturales de plagas en cultivos de frambuesa. Se capturaron artrópodos predadores y parasitoides en 13 chacras, y se identificaron diferentes rasgos funcionales de estos enemigos naturales. Los resultados mostraron que los índices de diversidad funcional de enemigos naturales no fueron afectados por las variables de manejo consideradas. Sin embargo, se observaron respuestas diferenciales en los diferentes grupos funcionales analizados. Por ejemplo, depredadores generalistas caminadores y parasitoides especialistas voladores fueron más abundantes en parcelas sin control de malezas. Estos hallazgos resaltan la importancia del control de malezas en la abundancia de enemigos naturales y la necesidad de considerar los diferentes grupos funcionales al diseñar estrategias de manejo para el control biológico de plagas en sistemas agrícolas.

Through the analysis of functional traits, the influence of management practices (weed control and irrigation system) on the abundance and diversity of natural enemies was examined for raspberry crops. Predatory and parasitoid arthropods were captured in 13 farms, and different functional traits of these natural enemies were identified. The results showed that the functional diversity of natural enemies was not affected by the management variables. However, differential responses were observed in the different functional groups. For example, walker generalist predators and flying specialist parasitoids were more abundant in plots without weed control. These findings highlight the importance of weed control in the abundance of natural enemies and the need to consider different functional groups when designing management strategies for biological pest control in agricultural systems.
