Entomological diversity in horticulture and in urban environments
Beneficial entomofauna plays a crucial role in the regulation of pest populations as well as in the functioning of ecosystems. The Agricultural Ecology and Horticultural Systems group studies how to promote this diversity so that it can fully play its roles, as well as the impact of methods of managing crops or climatic change on it.
Biological control of pests with the aid of auxiliaries
The use of auxiliaries to combat pests is increasingly a practice that horticulturalists are adopting. The group aims to develop methods for maximising this type of control in horticultural crops, as well as to better understand the numerous interactions which exist between pests and auxiliaries.
Relations between plants and insects
Insects have developed relationships which are sometimes very close to plants. Among other things, the group’s work attempts to study these relationships to optimise crop management and determine which plants to use to attract certain beneficial insects near the crops. It also studies the natural defence system of plants against herbivores.
Urban agriculture and greening of buildings
Urban agriculture allows urban dwellers to renew their links with nature and access local produce, while greening of buildings allows more plants to be integrated into cities as green roofs or walls. The group is interested in the crops or plants with the highest potential in urban areas, as well as their safety and quality.
Sustainable horticultural production systems
To ensure the sustainability of farms and supply, horticultural production requires the maintenance of soil fertility and precise management while ensuring the protection of the environment. The search for new technologies as well as the trialling of new technical routes within the group will meet the demand of producers while respecting societal and environmental requirements.
Dendrology and arborisation
Climate change is a major concern, and urban and suburban areas are particularly exposed. The ecosystem services provided by the greening of our living spaces are particularly important, making it possible to create a sustainable and pleasant habitat by limiting heat islands. Planting trees and associated plants is an integral part of the response to these challenges. To anchor this approach in the long term, a wide range of dendrological, pedological and ecosystem knowledge of ornamental plants is essential.
All these skills are centralised in a team that will be able to advise and support you in your arborisation questions and choices, as well as in the management of your tree patrimony.
