Gestion territoriale des adventices : effets des propriétés du paysage sur les communautés adventices et sur leur régulation par les carabidae

2015

Landscape-scale management is known to affect pest and biodiversity levels in agroecosystems. Here, we focus on the lanscape drivers of arable weeds, first by reviewing evidence of direct landscape effects on weed species richness and abundance and then by analyzing current knowledge on landscape effects on carabids, which are well-known weed seed predators that contribute to the biological regulation of weeds. Our analysis shows that (i) heterogeneous landscapes usually harbor higher species richness and more diversified communities than simple ones, (ii) total weed and carabid abundances appear seldomly affected by the landscape context of arable fields and (iii) weed seed predation in fi…

Influence du colza et des prairies à différentes échelles spatiales sur l’abondance des carabes prédateurs de graines d’adventices

2014

National audience; Les coléoptères carabidae sont très représentés dans les cultures annuelles où ils peuvent contribuer au contrôle biologique de bioagresseurs. Ainsi, les carabes omnivores et granivores consomment des quantités importantes de graines de plantes adventices. Des études récentes suggèrent que la réponse des communautés de carabes à l’organisation du paysage est en partie dépendante de leur guilde trophique. Néanmoins, dans le cas de carabes consommateurs de graines d’adventices, on connait peu les types d’occupation du sol qui les favorisent au sein d’un paysage et l’échelle spatiale à laquelle ces insectes répondent. Ici, nous avons analysé les variations de l’abondance de …

Can obligatory omnivore carabids be useful for the biocontrol of weeds?

2017

National audience; Many thousands of carabid individuals exist in farm fields, in communities of carnivore and opportunistic (e.g. granivores) and obligate omnivore guilds. As carabids can eat a substantial amount of weed seeds they are considered as credible biocontrol agents for the regulation of weeds in arable fields. Some studies have suggested that “granivores” are more important biocontrol agents than obligate omnivorous species. Yet, in some instances, obligate omnivores are very abundant and appear to drive the predation of weeds leading some authors to question whether specialist natural enemies are better. Moreover, niche complementarity, facilitation and interference (i.e. intra…

Species-specific prey choice of carabid beetles in European cereal fields

2017

National audience; Trophic interactions between species in agroecosystems provide key regulation ecosystem services and therefore also determine the dynamics, robustness and resilience of service provision. To achieve international goals of reducing application of pesticides without compromising key provisioning ecosystem services such as crop yield, recent research attaches importance to the biological control potential of carabid beetles. However, apart from feeding on pest species and weed seeds, carabids also consume non-pest prey (alternative prey) such as collembolans and earthworms, which can play a contradictory role in the efficacy of pest and weed control. Most carabids are descri…

Toward a better prediction of in-field weed regulation by carabid beetles in European arable landscapes

2019

International audience; Arable agriculture is still highly reliant on herbicides to manage weeds. As part of the necessary shift towards a reduction in pesticide use, the regulatory effect of seed-eating carabid beetles on weeds has received increasing attention in agroecological research. While strong evidence points to carabids exerting a regulatory effect on certain weed species, it is difficult to predict whether a particular assemblage of carabid species will drive the function of weed seed predation in field conditions. There are also uncertainties about which key local and landscape-scale factors affect the function of weed seed predation. In this paper, we report on specific researc…

Carabid ecosystem services

National audience; A major challenge for the future of agriculture is to manage ecological, pest control services with the aim of reducing pesticide use with little or no additional risk to productivity and food security. However, generic findings for in-field and landscape management supporting natural enemy abundance and their impact on various pest groups are still scarce. The resilience of pest control service when pesticide use level gradually decreases is also poorly documented.

Effects of seed and carabid densities on the weed seed predation service

2017

National audience; Farming relies heavily on pesticides in order to maintain/increase crop production, yet, awareness of the adverse effects of pesticides on the environment and on biodiversity has triggered the search for alternative, non-chemical, pest management strategies. In arable systems, weeds remain one of the most challenging management issue. Recent research suggest that the depletion of weed seeds by naturally occurring seed consumers could impact the dynamics of problematic weeds and in temperate systems, carabid beetles are the main invertebrate consumers of weed seeds. However, predicting weed seed depletion rates in field conditions remains difficult, as carabid trophic resp…

Les coléoptères carabiques sont-ils plus sélectifs face à un risque de prédation ou de compétition ?

2017

Le temps nécessaire à l’évaluation et à l’acceptation d’une ressource est directement lié à sa qualité. Ainsi, les individus s’approvisionnant dans un milieu naturel font face à un compromis entre vitesse de prise de décision et qualité de la ressource (speed-accuracy trade-off). Si la qualité de la ressource est un élément important pour favoriser sa valeur adaptative (fitness), le temps nécessaire au processus de décision n’est plus disponible pour d’autres tâches essentielles comme la vigilance. De plus, une prise de décision trop longue expose aussi les individus à un risque plus important de compétition et de perte d’opportunités. On s’attend à ce que des animaux confrontés à un risque…

High-tech agriculture: farmers risk being ‘locked in’ to unsustainable practices

2019

Prod 2019-24b SPE GESTAD INRA; International audience; Since World War II, Europe’s agricultural sector has been very receptive to new technology, and the result has been staggering productivity gains – for four generations, farmers have produced more than their parents did. At the same time, however, agricultural prices have fallen around the world and price subsidies have been cut. This has led to a cruel paradox: while farmers have never produced so much, many can no longer make a living from farming.

Ecological networks in managed ecosystems: Connecting structure to services

2017

Introduction Ecological networks represent a cornerstone of ecology: they describe and evaluate the links between form and function in multispecies systems, such as food-web structure and dynamics, and they connect different scales and levels of biological organization (Moore and de Ruiter, 2012; Wall et al., 2015). These properties of being able to elucidate both the structure within complex systems and their scaling indicate that ecological networks and network theory could be widely applied to practical problems, including management decision-making processes such as the design of nature reserves and the preservation of ecosystem services. While the study of networks – initially food-web…

Stability of consumption pattern in two seed eating carabid species

2017

SPEGESTADDOCT INRA; Carabids can eat a substantial amount of seeds of weeds per day and are considered as credible biocontrol agents for the regulation of weeds in arable fields. Carabids species belong to either granivore, omnivore or carnivore trophic guilds and we expected each of these to have specific patterns of weed seed consumption and specific responses to biotic interactions. These differences will impact the total predation rate of a carabid community and may also explain why it is difficult to predict the efficiency of carabid biocontrol service. To test this expectation, we looked at the consumption pattern of two species of carabids species common in arable fields, one known a…

In agriculture, landscape management research has proven extremely valuable for explaining species amount, such as how species capture and utilize changed landscape resources to maintain population size and community diversity. What is surprising is the apparent lack of comparable studies on the effects of landscape properties and management on species fitness. Here, we search for "pathological" situations where landscape effects on farmland plant amount mask significantly different effects on fitness. We examined the case of 83 weed species in 256 fields distributed across the UK national scale. Whether at the local scale of the neighborhood or the larger scale of 2 km, we find landscape e…
