From a plant-protection point of view, corn is attacked by many enemies (multivorous and specialized), which significantly reduce the yield, in individual years they multiply massively and are able to completely compromise the harvest. In recent years, a new corn enemy has appeared, the western corn rootworm (Diabrotica virgifera virgifera Le Conte), which is causing significant problems. For this purpose, the appearance and population dynamics of the species were followed. The studies were conducted during the period 2022-2023 in corn fields in the region of Chirpan and Plovdiv on an area of 1000 ha. Carrying out monitoring in the region of Central- South Bulgaria is important for establishing the spread of the species and organizing a whole complex of phytosanitary measures to limit the spread of the western corn rootworm.
