The observation was made during sample collection in an open-field experiment conducted at the University of Forestry’s experimental station in Sofia. The experiment aimed to assess how intercropping kale (Brassica oleracea L. var. acephala) with various companion plants would impact the activity of key pests and their natural enemies. This is the first record of the host-parasitoid association between Pieris rapae (Linnaeus, 1758) and Phryxe nemea in Bulgaria.enhostPieris rapaeTachinidaeArticle
