O olival é uma cultura de elevada importancia na região de Trás-os-Montes, constituindo o olival tradicional o principal sistema de produção. A mobilização do solo para controlo de infestantes, é tradicionalmente, praticada nos olivais desta região, no entanto esta prática aumenta a susceptibilidade dos solos à erosão e pode perturbar a biota do solo e as suas interações. O conhecimento acerca do efeito desta p...
Plant diversity often contributes to the shape of arthropod communities, which in turn supply important ecosystem services. However, the current biodiversity loss scenario, particularly worrying for arthropods, constitutes a threat for sustainability. From a trait-based ecology approach, our goal was to evaluate the bottom-up relationships to obtain a better understanding of the conservation of the arthropod fu...
Insects of the order Coleoptera play an essential role in agricultural sustainability by supporting many ecosystem services (such as biological control, nutrient cycling or pollination). In agroecosystems, the Coleoptera community may be influenced by the surrounding landscape, which can provide living resources, like food or shelter, during different seasons, originating spillover movements between different e...
1. The intensification of urban and agricultural use in the landscape is the major driver of biodiversity loss and the consequent decrease of ecosystem services provided by insects. Syrphids are important ecosystem service providers, including pest regulation, pollination, and matter decomposition. 2. Understanding how the surrounding landscape to crops affects syrphids is essential to implementing strategies t...
Arthropod populations from agricultural fields sometimes depend on the surrounding landscape structure, both composition and configuration, which affects multiple life-history traits of arthropods such as resources for survival, dispersion or death risk (e.g., predation or parasitism). Moreover, the effect of the landscape may vary with the distance to the crop, depending on factors such as the organism require...
From late summer onwards, the third instar larvae of the olive fly, Bactrocera oleae (Rossi) (Diptera: Tephritidae), leave the fruit and fall in the soil to pupate. The behavior of the larvae in the soil (the time it takes to bury and the pupation depth) affects their exposition to predators and, consequently, their survival. On the other hand, this period coincides with the rain season, interfering with pupati...
The family Coccinellidae (Coleoptera) includes important predatory natural enemies in agricultural crops. To survive, this group uses different occurring resources across the landscape; therefore, the landscape can influence the Coccinellidae community in agroecosystems. In this context, this work aims to evaluate the response of the Coccinellidae community to the landscape context within a gradient of distance...

The olive tree (Olea europaea L.) is among the oldest and most widespread crops in the Mediterranean basin. Portugal is the third olive producer in the European Union, and Trás-os-Montes region, located in northeastern Portugal, is the second Portuguese producing olive region. The olive moth, Prays oleae (Bernard) (Lepidoptera: Praydidae) is a key olive pest in Trás-os-Montes. This pest is a natural host/prey o...
Earwigs (Dermaptera: Forficulidae) are omnivorous insects, feeding on a variety of plants and animal material and are described as natural control agents of pests in several agroecosystems. Earwigs are abundant in olive orchards and their adult stage overlaps in time and space with the pupae stage of the main olive pest, the olive fly Bactrocera oleae (Rossi). However, the role of earwigs as natural control age...
