Palomena prasina (L.) (Hemiptera: Pentatomidae) and Gonocerus acuteangulatus (Goeze) (Hemiptera: Coreidae) are new pests in French hazel orchards (Corylus avellana L., Corylaceae). Knowing the symptoms in growing hazelnuts resulting from pests feeding on them is important for risk assessment and risk management. Insects were isolated in net sleeves...
Uncertainty about the taxonomic status and the specificity of a species commonly prevent its consideration as a candidate for biological control of pest organisms. Here we use a combination of molecular analysis and crossing experiments to gather evidence that the parasitoid wasp Ganaspis brasiliensis, a candidate for biological control of the inva...
Dicyphus bolivari Lindberg and Dicyphus errans (Wolff) (Hemiptera: Miridae) are naturally widespread in many crops with low-pesticide pressure, where they prey upon several arthropods, including the tomato pinworm Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae). However, their efficacy as biological control agents (BCAs) of this pest needs furth...

Project (1)
French hazel orchards are damaged by the green shield bug (GSB), Palomena prasina (Hemiptera: Pentatomidae). P. prasina is not exclusive to Corylus avellana. Adults and nymphs need to feed from different plant species. Plant diversity and habitats provided by hedges increase GSB population in orchards borders. Hedge composition could be a key issue between the pest and its natural enemies. Indeed, some plant species provide food sources and habitats for natural enemies.
Current tendencies to reduce the application of chemical agro-protections lead to several ecofriendly strategies to reduce the GSB attacks to more acceptable levels. Plant management is one of them. Making the environment less suitable for the pest survival and more suitable for natural enemies should lead to pest population reduction. Indeed, (1) control of host plants can reduce the available resources for the GSB (i.e. fruits, pods and seed for adults) during its key life stages ; (2) reduction of alternative plant resources during the vegetative phase of hazel trees and competitive host plants during hazel fructifications may negatively impact edge GSB populations; (3) promoting plant species providing suitable food sources and habitats for natural enemies without supporting the pest species may reduce GSB populations.
The project will aim at developing plant management solutions to reduce pest damages in hazel orchards by : (1) studying the dynamics of the populations according to plant diversity of hedges, (2) assessing the role of the host plants in the maintenance and/or in the dispersal of the pest, (3) identifying natural enemies and their hosts (such as parasites and parasitoids) and finally (4) studying the dispersal abilites of adults and nymphs in fields.
