| In conservation biological control, flowers can be used to increase the biological control potential of parasitoids, which benefit from the offered food sources. Besides exhibiting exploitable nectar, flowers should preferably be olfactorily attractive, as highly attractive flowers are easily located, reducing the time spent searching for food and subsequently increasing the per capita host searching efficiency. In this study we thus focused on the olfactory attractiveness of Fagopyrum esculentum Moench (Polygonaceae), Centaurea cyanus L. (Asteraceae) and Vicia sativa L. (Fabaceae) to Cotesia rubecula (Marshall, 1885) (Hymenoptera: Braconidae), a larval parasitoid of the cabbage pest Pieris rapae (Linnaeus, 1758) (Lepidoptera: Pieridae). With a Y-tube... |

| Organic liquid preparations contain higher of bacteria, fungi, actenomycets, N-fixers and P-solubilizers. Form the studies it is evident that beejamrutha is used on the day of preparation and jeevamrutha to be used between 9 to 12 days after preparation. The application of these liquid formulations would supplement the application of biofertilizers and they can be prepared easily by locally available materials by the farmers, in rural area. |

| Ants are challenged with disease transmission and microbial hygiene due to a life in densely populated long-lived ant nests. To improve hygiene ants use different ways to reduce microbial growth. They groom their bodies with (i) antimicrobial excretions from their metapleural and poison glands, they (ii) associate with bacterial symbionts capable of producing antibiotics, or they (iv) eat microbial spores. These defenses extend beyond the individual ant, as ants may groom nest mates, food substrates or nesting material. Defenses may even extend beyond the nest and affect mutualistic partners. For example, ants in specialized myrmecophytic ant-plant interactions have been shown to reduce pathogen loads on their host plants. Here we tested if wood ants... |

| The aim of this thesis, conducted over six growing seasons (20032008), is to define new measures for reducing the use of fungicides and in particular, copper fungicides, for the control of apple scab (V. inaequalis) in organic apple production. Special emphasis is put on primary scab infection control during spring season. An original approach is proposed for defining a specific spray timing involving spraying during the infection processes, especially before fungal penetration, determined by the RIMpro software warning system. This ‘during-infection’ spray strategy allows reducing from 30 to 50% the amount of fungicide usually used for effective apple scab control, on high scab-susceptible cultivars. The field study shows that six alternative products... |

| Cadmium(Cd) uptake by cocoa has recently attracted attention, after the European Union (EU) decided to establish values for tolerable Cd concentrations in cocoa products. Bean Cd concentrations from some cocoa provenances, especially from Latin America, were found to exceed these values. Cadmium uptake by cocoa is expected not only to depend on a variety of soil factors, but also on plant and management factors. In this study, we investigated the influence of different production systems on Cd uptake by cocoa in a long-term field trial in the Alto Beni Region of Bolivia,where cocoa trees are grown inmonocultures and in agroforestry systems, both under organic and conventional management. Leaf, fruits and roots of two cultivars were sampled fromeach... |

| In December 2016, CORE Organic Cofund consortium, including 26 partners from 19 countries, launched the new call supporting the European transnational organic research. The applicants participated in a two steps section procedure where in the first step out of 50 proposals 33 were invited to the second step where 12 research proposals were selected for the funding. The CORE Organic Cofund consortium spent in the call nearly 14 million Euro including cofunding from the European Commission. The selected project proposals are distributed across four thematic areas agreed on the level of consortium: Plant production systems, animal feed, livestock systems and organic food processing. The planned project activities should start from Spring 2018 and be... |

| Principe : attirer, multiplier les ennemis naturels en leur fournissant des abris, leur fournissant de la nourriture : proies alternatives (coccinelles), ressources florales (pour les adultes de syrphes, chrysopes, microhyménoptères) Il faut donc bien connaître les ennemis naturels (cycle de vie, besoins biologiques, plantes-hôtes), sélectionner des plantes-hôtes convenables aux ennemis naturels et adaptées à une mise en place sur l’exploitation, co-concevoir avec les producteurs des stratégies pour optimiser le service rendu et minimiser les contraintes Ce poster présente les résultats récents du GRAB sur ce thème. Tous les essais ont été réalisés sur des exploitations maraîchères en AB. |
