Zur Kenntnis der parasitischen Hymenopteren im Winterraps (Brassicaceae: Brassica napus) in Baden-Württemberg

In 2023, surveys regarding the antagonist fauna of the green peach aphid, the rapeseed beetle, the large rapeseed weevil, the cabbage pod weevil and the cabbage pod gall midge were carried out on rapeseed and yellow mustard flowers, rapeseed stalks and rapeseed pods at various locations in Baden-Wuerttemberg. Twelve parasitic wasp species were identified from the peach aphid and could be assigned to five families (Aphelinidae, Braconidae, Megaspilidae, Pteromalidae and Figitidae). In addition, three species of parasitoids from the family Ichneumonidae, known as parasitoids of the rapeseed beetle, were identified. Seven parasitic wasp species from four families (Pteromalidae, Eurytomidae, Ichneumonidae, Braconidae) were identified as opponents of the cabbage pod weevil. Five species of parasitic wasps were identified as parasitoids of the cabbage pod gall midge and could be assigned to three families (Platygastridae, Torymidae, Eulophidae) within the framework of morphological analyses and identifications.
