Recherche et évaluation des parasitoïdes oophages indigènes de la punaise invasive Halyomorpha halys

Abstract : Halyomorpha halys is an invasive pest native from South-Est Asia. Since its introduction in North America it has become a key pest of many crops. H. halys was accidentally introduced into France around 2012 and has spread all over the territory. This pest is a potential threat to French orchard especially as no efficient insecticide is allowed. Development of a sustainable management is necessary. One solution can be biological control with egg parasitoids. The goal of the training period is on the one hand, complete European study about H. halys egg parasitoids with French data and on the other evaluate biodiversity and species distributions of French egg parasitoids. For that a two‐year field survey was conducted exposing H. halys egg masses in different types of habitats. Samples were identify using barcoding method. Result show that very few species can use H. halys as host. They belong to genius Anastatus and Ooencyrtus. In addition, Trissolcus japonicus the main Asian regulator of H. halys was not detected despite its presence in Italy and Swiss. Current results guide the project to T. japonicus introduction.
