Structural complexity of arthropod guilds is affected by the agricultural landscape heterogeneity generated by fencerows

Abstract: Intensive farming imposes harsh conditions impeding the persistence of most arthropod species within crop fields. Hence, arthropods surviving the unfavourable conditions prevailing within crop fields may disperse towards nearby uncropped margins, such as fencerows. Here, we evaluate the influence of landscape heterogeneity on the abundance of different guilds, particularly herbivores and their natural enemies. Said heterogeneity mostly derives from fencerow network density. Hence, we developed an approach base… Show more

“…They found that A. colemani significantly reduced pest populations in the arugula crop, but did not provide increased control in pepper, which provides evidence of the importance of the composition of the system for an efficient pest control. In addition, spontaneous vegetation and hedgerows surrounding crops have also been evaluated in Argentina (Molina et al 2016, Salas-Gervassio et al 2016. For example, Salas-Gervassio et al (2016) found that spontaneous wild solanaceous plants surrounding tomato crops could increase the control of the moth Tuta absoluta (Meyrick, 1917) (Lepidoptera: Gelechiidae), allowing the interaction with the parasitoid Pseudapanteles dignus (Muesebeck) (Hymenoptera: Braconidae).…”

“…En los agroecosistemas, el componente natural y semi-natural está representado por fragmentos incluidos en una matriz de suelo destinado a la agricultura. Estos remanentes naturales proporcionan heterogeneidad al ambiente, con condiciones más estables y mayor diversidad y complejidad en la estructura de la comunidad vegetal (Poggio et al 2010(Poggio et al , 2013Molina et al 2016), actuando como refugio para las especies tanto a escala local como de paisaje (Medan el al. 2011;Molina et al 2014).…”

“…2011;Molina et al 2014). La comunidad vegetal de estos ambientes es la base de las tramas tróficas, ya que mantienen poblaciones permanentes de artrópodos que sustentan niveles tróficos superiores y cumplen una función clave en la provisión de servicios ecosistémicos (Altieri and Nicholls 2007;Medan et al 2011;Molina et al 2014Molina et al , 2016Lindgren et al 2018). La diversidad y la presencia de poblaciones viables de los insectos es esencial para la provisión de servicios de polinización y regulación de poblaciones de insectos plaga (Öckinger and Smith 2007;Molina et al 2014Molina et al , 2016.…”
