Afin de favoriser également la régulation naturelle des ravageurs, des mélanges de semences pour bandes fleuries annuelles ont été développés. Ceux-ci sont axés sur les exigences des antagonistes des ravageurs des cultures (en particulier les criocères des céréales et les pucerons). Dans les bandes fleuries pour auxiliaires – ensemencées avec diverses plantes sauvages et cultivées – de même que dans certaines cultures adjacentes, on a trouvé nettement plus d’auxiliaires. Par rapport aux parcelles témoins, on a recensé 40 à 53 % de moins de criocères des céréales dans les parcelles de blé d’automne où avaient été semées des bandes fleuries pour auxiliaires, et 75 % de moins de pucerons dans les parcelles de pommes de terre. De plus, les dommages aux plantes provoqués par les criocères des céréales ont diminué de 61 %. Ces résultats montrent que les bandes fleuries contribuent non seulement à promouvoir la biodiversité, mais qu’elles permettent aussi de réduire les ravageurs. Elles représentent ainsi une plus-value pour la production agricole. D’ici 2017, deux mélanges de semences commercialisables devraient être prêts pour le nouveau type de surface de promotion de la biodiversité «Bandes fleuries pour les pollinisateurs et les autres organismes utiles».

[CBNPMP-Thématique] MalherbologieRésumé : Providing key resources to animals may enhance both their biodiversity and the ecosystem services they provide. We examined the performance of annual flower strips targeted at the promotion of natural pest control in winter wheat. Flower strips were experimentally sown along 10 winter wheat fields across a gradient of landscape complexity (i.e. proportion non-crop area within 750 m around focal fields) and compared with 15 fields with wheat control strips. We found strong reductions in cereal leaf beetle (CLB) density (larvae: 40%; adults of the second generation: 53%) and plant damage caused by CLB (61%) in fields with flower strips compared with control fields. Natural enemies of CLB were strongly increased in flower strips and in part also in adjacent wheat fields. Flower strip effects on natural enemies, pests and crop damage were largely independent of landscape complexity (8–75% non-crop area). Our study demonstrates a high effectiveness of annual flower strips in promoting pest control, reducing CLB pest levels below the economic threshold. Hence, the studied flower strip offers a viable alternative to insecticides. This highlights the high potential of tailored agri-environment schemes to contribute to ecological intensification and may encourage more farmers to adopt such schemes.

Titre : Tailored flower strips promote natural enemy biodiversity and pest control in potato crops Type de document : Électronique Auteurs : Matthias Tschumi (1986-) ; Matthias Albrecht ; Jana Collatz ; Viktor Dubsky ; Martin H. Entling ; Adriana J. Najar-Rodriguez ; Katja Jacot (1971-) Année de publication : 2016 Article en page(s) : 1169-1176 Langues : Anglais (eng) Résumé : Sown flower strips are increasingly implemented within agri-environment schemes (AES) to increase functional biodiversity and ecosystem services such as pollination or natural pest control, but their effectiveness in achieving these goals remains poorly studied.
We tested the performance of experimentally sown annual flower strips specifically designed to promote natural enemies of aphids and their pest control services (tailored flower strips) in adjacent potato crops (n = 8) compared with control fields (n = 10). Flower strips consisted of 11 plant species providing abundant floral and extra-floral resources.
The abundance of key natural enemies of aphids (hoverflies, lacewings and ladybirds) and hoverfly species richness was greatly enhanced in tailored flower strips compared with potato control strips. This resulted in an average increase in the number of eggs deposited by hoverflies and lacewings by 127% and 48%, respectively, and a reduction in the number of aphids by 75% in adjacent potato crops.
Synthesis and applications. We conclude that tailored flower strips can be an effective agri-environmental measure to enhance natural enemies and aphid control in nearby crops. Indeed, tailored flower strips may help to reduce insecticide input in potato production as they significantly decrease the probability that action thresholds are reached. Promoting natural enemy abundance and diversity, as observed for hoverflies, may increase the stability of pest control and provide additional benefits to agro-ecosystems in terms of natural enemy conservation. We thus recommend establishing tailored flower strips as a promising management option to reconcile the objectives of ecological intensification and biodiversity conservation.

Titre : Targeted flower strips effectively promote natural enemies of aphids Type de document : Électronique Auteurs : Matthias Tschumi (1986-), Auteur ; Matthias Albrecht, Auteur ; Martin H. Entling, Auteur ; Katja Jacot (1971-), Auteur Année de publication : 2014 Article en page(s) : 131-135 Langues : Anglais (eng) Résumé : Sown wildflower strips are increasingly established within agri-environmental schemes in Europe and worldwide. Their goals include the promotion of biodiversity, pest control or pollination services. Here, we tested whether a new type of flower strip targeted to promote natural enemies controlling aphids and other wheat pests are more effective in achieving this goal than an already implemented wildflower strip type aimed at biodiversity conservation. We found two to five times higher numbers of key aphid antagonists, Syrphidae, Coccinellidae and Chrysoperla carnea (Chrysopidae), in the targeted flower strip compared to wildflower strips designed for biodiversity conservation. The targeted use of flowering plants, providing fundamental resources for natural enemies of crop pests, might significantly contribute to an efficient integrated pest management.

[CBNPMP-Thématique] Coadaptation, coévolution, symbiose (dissémination, pollinisation)Résumé : Floral plantings are promoted to foster ecological intensification of agriculture through provisioning of ecosystem services. However, a comprehensive assessment of the effectiveness of different floral plantings, their characteristics and consequences for crop yield is lacking. Here we quantified the impacts of flower strips and hedgerows on pest control (18 studies) and pollination services (17 studies) in adjacent crops in North America, Europe and New Zealand. Flower strips, but not hedgerows, enhanced pest control services in adjacent fields by 16% on average. However, effects on crop pollination and yield were more variable. Our synthesis identifies several important drivers of variability in effectiveness of plantings: pollination services declined exponentially with distance from plantings, and perennial and older flower strips with higher flowering plant diversity enhanced pollination more effectively. These findings provide promising pathways to optimise floral plantings to more effectively contribute to ecosystem service delivery and ecological intensification of agriculture in the future.
