| Summary: | The brown marmorated stink bug (Halyomorpha halys (Stål, 1855)) is an extremely polyphagous invasive insect originating from East Asia. It causes damage by feeding on fruit trees and shrubs, legumes, forest trees, and ornamental shrubs and trees. The pest has successfully established in North America and Europe and causes economic damage to agricultural production. The first discovery of H. halys in Croatia occurred in 2017 in the coastal region in Rijeka. In 2018, the pest was sporadically observed in urban areas of Sveta Nedelja, Zagreb and Vukovar, and a total of 22 specimens of H. halys were found in single and multi-family houses in eight locations. The discovery of the species in the continental part of the country is evidence of the spread of this species in Croatia. During 2019, the first mass occurrence of the pest was detected in the rural area of Zagreb (Drenčec) in a soybean field. A total of 723 specimens of H. halys were identified. The average number of stink bugs per 10 plants was 14 specimens, which poses a serious threat to soybean production in the area. The very rapid spread of the pest from urban to rural areas and the establishment of its local populations is evidence of the invasive nature of the species and a warning signal for farmers in Croatia. To prevent the spread and mass occurrence of H. halys on agricultural land and to minimise possible damage to agricultural production, it is necessary to constantly monitor the pest and, if necessary, to take appropriate protective measures in agriculture.
