Olive growing has been intensified through the simplification of agricultural landscapes. In order to rethink the environmental drawbacks of these practices, conservation biological control techniques have been examined. In this work, and its natural enemy were monitored to account for the effects of the amount and diversity of different land-uses. We found that showed an attraction to areas with high abundances of but this predator did not display any affection by the different land-uses. Inversely, abundance was lower in diverse landscapes and higher in simplified ones. Importantly, higher abundances of were related to lower infestation levels of in the late part of the season. These results corroborate the attraction of to the olive moth, highlighting the potential of as a biological control agent of this pest, assert that the promotion of land-use diversity can reduce and confirm that landscapes dominated by olive groves can promote this pest. The present study aims at contributing to the discussion about the management of agricultural ecosystems by providing farmers with sustainable alternatives that do not have harmful effects on the environment and public health.
通过简化农业景观，橄榄种植得到了强化。为了重新思考这些做法对环境的不利影响，人们对保护生物防治技术进行了研究。在这项工作中，对[具体物种1]及其天敌[具体物种2]进行了监测，以评估不同土地利用方式的数量和多样性所产生的影响。我们发现，[具体物种1]对[具体物种2]数量丰富的区域表现出吸引力，但这种捕食者并未受到不同土地利用方式的影响。相反，[具体物种2]在多样化景观中的数量较低，而在简化景观中的数量较高。重要的是，在季节后期，[具体物种2]数量较多与[具体害虫]的低侵染水平相关。这些结果证实了[具体物种1]对橄榄蛾的吸引力，突出了[具体物种1]作为这种害虫生物防治剂的潜力，表明促进土地利用多样性可以减少[具体害虫]，并证实以橄榄林为主的景观会助长这种害虫。本研究旨在通过为农民提供对环境和公众健康无有害影响的可持续替代方案，为有关农业生态系统管理的讨论做出贡献。
