“…Particular attention has been devoted to the structure of beetle bank vegetation (large carabid species prefer dense but homogeneous vegetation (Brose, 2003) while smaller ones are positively correlated with heterogeneous vegetation (Rouabah et al, 2015)) but little is known about the benefits they may offer to natural enemies visiting flowers (Ramsden et al, 2015). Hence, a challenge would be to conceive herbaceous strips that optimize both the structure of the vegetation and the provision of flower resources, i.e.…”

Spatial diversification of crop and non-crop habitats in farming systems is promising for enhancing natural regulation of insect pests. Nevertheless, results from recent syntheses show variable effects.One explanation is that the abundance and diversity of pests and natural enemies are affected by the composition, design and management of crop and non-crop habitats. Moreover, interactions between both local and landscape elements and practices carried out at different spatial scales may affect the regulation of insect pests. Hence, research is being conducted to understand these interdependencies.However, insects are not the only pests and pests are not the only elements to regulate in agroecosystems. Broadening the scope could allow addressing multiple issues simultaneously, but also solving them together by enhancing synergies. Indeed, spatial diversification of crop and non-crop habitats can allow addressing the issues of weeds and pathogens, along with being beneficial to several other regulating services like pollination, soil conservation and nutrient cycling. Although calls rise to develop multifunctional landscapes that optimize the delivery of multiple ecosystem services, it still represents a scientific challenge today. Enhancing interdisciplinarity in research institutions and building interrelations between scientists and stakeholders may help reach this goal. Despite obstacles, positive results from research based on such innovative approaches are encouraging for engaging 2 science in this path. Hence, the aim of the present paper is to offer an update on these issues by exploring the most recent findings and discussing these results to highlight needs for future research.

“…Several studies have analyzed the functional composition of consumer groups in response to environmental changes (de Sassi et al 2012, Börschig et al 2013, Penone et al 2013, Schuldt et al 2014. However, many of these studies were conducted in a land-use context (Woodcock et al 2010, Birkhofer et al 2015a, Rouabah et al 2015, and only very few focused on effects of plant diversity (Milcu et al 2013, Schuldt et al 2014. Hence, our knowledge of how the functional composition of consumer communities is affected by plant diversity remains limited (Lavorel et al 2013), but is essential to predict the consequences of plant diversity change for consumer-driven ecosystem services, such as pest-control.…”

Changes to primary producer diversity can cascade up to consumers and affect ecosystem processes. Although the effect of producer diversity on higher trophic groups have been studied, these studies often quantify taxonomy-based measures of biodiversity, like species richness, which do not necessarily reflect the functioning of these communities. In this study, we assess how plant species richness affects the functional composition and diversity of higher trophic levels and discuss how this might affect ecosystem processes, such as herbivory, predation and decomposition. Based on six different consumer traits, we examined the functional composition of arthropod communities sampled in experimental plots that differed in plant species richness. The two components we focused on were functional variation in the consumer community structure (functional structure) and functional diversity, expressed as functional richness, evenness and divergence. We found a consistent positive effect of plant species richness on the functional richness of herbivores, carnivores, and omnivores, but not decomposers, and contrasting patterns for functional evenness and divergence. Increasing plant species richness shifted the omnivore community to more predatory and less mobile species, and the herbivore community to more specialized and smaller species. This was accompanied by a shift towards more species occurring in the vegetation than in the ground layer. Our study shows that plant species richness strongly affects the functional structure and diversity of aboveground arthropod communities. The observed shifts in body size (herbivores), specialization (herbivores), and feeding mode (omnivores) together with changes in the functional diversity may underlie previously observed increases in herbivory and predation in plant communities of higher diversity

“…Haschek et al (2012) found that Amara similata oocyte numbers were negatively related to distance from the nearest fallow, and that models best explaining the nutritional condition of male Poecilus cupreus and male A. similata contained parameters relating to percentage of surrounding crop area and distance from the nearest fallow, respectively. As grassy fallows and other non-crop areas represent important refuges for carabid beetles (Collins et al 2002;Rouabah et al 2015), the poorer condition of individuals needing to search further afield from these habitats may be related to scarcity of food resources. Indeed, pest abundance (a measure of prey availability) proved to be the most important factor explaining these measures of carabid fecundity and fitness, suggesting that knock-on effects of landscape factors on pest abundance are probably a more important influence on these characteristics in carabids than direct landscape effects.…”

“…Burgio et al 2006) as well as some spiders (e.g. Meek et al 2002) often show a greater diversity in flowering field margins than other margins or habitats, although vegetation structure species composition, age, and management are also important (Rouabah et al 2015; reviewed by Haaland et al 2011). Field margins have been shown to have positive effects on the abundance of these predators in adjacent crops including OSR; Frank and Nentwig (1995) and Frank (1997) showed species richness of carabid beetles and spiders in OSR was positively influenced by adjacent flowering 'weed' strips but the number of species and individuals was reduced with distance in-crop from the margin (see also Büchs 2003).…”

There is an urgent need to develop sustainable and environmentally benign integrated pest management (IPM) strategies for arable crops. The enhancement and manipulation of naturally occurring populations of the natural enemies of crop pests through habitat management for 'conservation biological control', as well as habitat management to manipulate populations of the pests themselves, have the potential to become major components of successful IPM strategies. We review the studies that have contributed to our current understanding of how the crop margin, local landscape, and regional landscape can influence pollen beetle Brassicogethes aeneus (syn. Meligethes aeneus) (Coleoptera: Nitidulidae) abundance and damage to oilseed rape crops (Brassica napus), and the efficacy of their natural enemies. We also discuss how habitat management across these multiple scales may improve pollen beetle control, reducing the need for insecticide use and contributing towards sustainable production of this important crop which is grown on increasing areas for both food and fuel.
