“…Pterostichus, as in our study. This may promote the functional diversity of ecosystem service providers in adjacent agricultural fields, and may lead to enhanced pest suppression (Schirmel et al 2016;Medeiros et al 2018). Šustek (1994) and Taboada et al (2010) stated that the structural type of vegetation is likely to have more effect on carabid species than plant species.…”

“…Different types of margin habitats have been identified: headlands with herbaceous vegetation, tree stands or tree lines, mid-field tree belts, shelterbelts, shrubby areas, roadsides, mid-field forests or midfield woodlots or forest islands, ditches, ponds, meadows, etc. (Šustek 1994, 1998Marshall and Moonen 2002;Kujawa et al 2006;Alemu 2016;Franin et al 2016;Schirmel et al 2016;Tscharntke et al 2016;Fusser et al 2017;Holland et al 2017;Ingrao et al 2017;Medeiros et al 2018). The multifunctional role of these habitats consists in: increasing the number of natural enemies of pests; increasing the biodiversity of wild organisms; providing primary food or alternative food sources for beneficial entomofauna, including pollinators, parasitoids and predators; providing sites for nesting, sheltering and overwintering of invertebrates, mammals and birds; reducing the use of chemicals in crops, and the transfer of pollutants to different areas of the landscape (e.g.…”

The aim of this study was to identify the role of field margin habitats in preserving the diversity and abundance of ground beetle assemblages, including potentially entomophagous species and those with conservation status in Poland. Research material was collected in 2006–2007 in four types of margin habitats – a forest, bushes, ditches and in two arable fields. Insects were captured into pitfalls, without preservation liquid or bait added to the traps. Traps were inspected twice a week, between May and August, and one sample was a weekly capture. In field margin habitats the most abundant species were Limodromus assimilis, Anchomenus dorsalis, Pterostichus melanarius and Carabus auratus. A lower abundance of species was noted on fields, with dominant Poecilus cupreus and P. melanarius. The group of zoophagous carabids found in our study includes 30 species from field margin habitats, i.e. 37.5% of all captured Carabidae taxa and 58.3% of all specimens. The share of aphidophagous species was 84.9% among bushes, 86.7% near ditches, and 88.0% in the forest habitat. Several species captured during the study are under protection in Poland. These include the partly protected Carabus convexus, which also has the status of near threatened species, the partly protected Calosoma auropunctatum, and Broscus cephalotes. Considering all the investigated field margin habitats, ground beetles were most numerous in the oak-hornbeam habitat, defined as bushes, formed predominantly by Prunus spinosa, Crataegus leavigata, Sambucus nigra and Rosa canina. Thus, this habitat was the most important reservoir/refugium for the ground beetles.

“…The ΔAICc is the difference between the AICc of a considered model and the best model, i.e., the model with the lowest AICc value (Burnham and Anderson 2002). Models with significant model fit (P values < 0.05), wAICc ≥ 0.1, and ΔAICc ≤ 2.5) were considered equally plausible at explaining the dependent variables (Medeiros et al 2018).

Landscape structure and crop management directly affect insect communities, which can influence agriculturally relevant ecosystem services and disservices. However, little is known about the effect of landscape structure and local factors on pests, natural enemies, and biological control services in the Neotropics. We investigated how environmental conditions at local and landscape levels affect Leucoptera coffeella (insect pest), social wasps (natural enemies), and the provision of biological control services in 16 Brazilian coffee plantations under different crop management and landscape contexts. We considered microclimatic conditions, coffee plantation size, and management intensity at the local level; and forest cover, landscape diversity, and edge density at the landscape level. Pest population, wasp communities, and biocontrol services were monitored in wet and dry seasons when L. coffeella outbreaks occur. We found that the amount of forest in the surrounding landscape was more important for explaining patterns than the local environment, landscape diversity, or landscape configuration. In both seasons, L. coffeella was negatively affected by forest cover, whereas biological control and richness and abundance of social wasps increased with increasing forest cover at multiple spatial scales. Moreover, biological control was positively correlated with wasp abundance during pest outbreaks, suggesting that social wasps are important natural enemies and provide pest control services within coffee plantations. We provide the first empirical evidence that forest cover is important for the maintenance of social wasp diversity and associated pest control services in a Brazilian coffee-producing region.

“…Nevertheless, the studies performed in Brazil include several features that can promote natural enemy abundance, diversity, and functionality in agroecosystems at different spatial scales. For example, at the landscape scale, noncrop habitats surrounding wheat crops are positively associated with hoverfly species richness in the south region of Brazil (Medeiros et al 2018). At the farm scale, farm diversity within and between crops and a reduction in the use of phytosanitary products with permitted use in organic agriculture increased the abundance and richness of whitefly predators, resulting in a more efficient and reliable whitefly biological control in organic tomato in the midwest region of Brazil (Togni et al 2018).…”

Brazilian Legislation Leaning Towards Fast Registration of Biological Control Agents to Benefit Organic Agriculture

Brazil is one of the main users of chemical pesticides in the world. These products threaten human and environmental health, and many of them are prohibited in countries other than Brazil. This paradigm exists in contrast with worldwide efforts to make the need for food production compatible with biodiversity conservation, preservation of ecosystem services, and human health. In this scenario, the development of sustainable methods for crop production and pest management such as organic agriculture and biological control are necessary. Herein, we describe how the process of registration of natural enemy-based products in organic agriculture is simpler and faster than the conventional route of chemical insecticides and can favor the development of the biological control market in Brazil. Since the regulatory mechanisms have been established in Brazil for organic agriculture, the number of biological control products registered has increased exponentially. Today, 50 companies and associations are marketing 16 species/isolates and 95 natural enemy-based products. Although this scenario presents a series of new opportunities to increase and stimulate a more sustainable agriculture in the country, biological control is not always aligned with the aims and philosophy of organic agriculture and agroecology. Therefore, we also argue that new research efforts are needed on understanding how conservation biological control strategies can be integrated with augmentation biological control to promote a sustainable agriculture under the concepts of organic agriculture and agroecology.
