The purpose of this work was to identify the species of ladybugs in the multiannual alfalfa fields in the Republic of Moldova. The main role of the overwhelming majority of ladybug species in the wild is the consumption of aphids, whiteflies, phytophagous mites, woolly lice and a wide range of other soft-bodied pests. In alfalfa fields, too, ladybirds consume plant lice, which damage the leaves and tender stalks of alfalfa by puncturing them and consume the sap, infecting the plant with viruses. According to updated data, 48 species of ladybugs have been identified in the Republic of Moldova. The most common species native for the Republic of Moldova include Hippodamia variegata, Coccinela septempunctata, Subcocinella 24-punctata, Propylea quatuordecimpunctata, P. quatuordecimpunctata, Scymnus frontalis and S. nigrinus. Less common in alfalfa fields are the species Hippodamia tredecimpunctata, Tytthaspis sedecimpunctata, Psyllobora vigintiduopunctata and Vibidia duodecimguttata. The last one was collected in one field and in a single specimen.
