First records of egg parasitoids of Halyomorpha halys (Stål, 1855) (Hemiptera, Pentatomidae) in Hungary
The brown marmorated stink bug (BMSB), Halyomorpha halys (Stål, 1855) (Hemiptera: Pentatomidae), is a highly polyphagous pest native to South Korea, North Korea, Japan, Taiwan, and China, which has become invasive in the Americas and Europe. H. halys has spread rapidly in invaded areas, causing crop damage and nuisance problems due to large overwintering populations. In recent years, several studies have investigated parasitoids of H. halys within its invaded regions. These studies recovered the coevolved parasitoids Trissolcus japonicus and Tr. mitsukurii in the regions. The present research surveyed parasitoids of H. halys in Hungary and cities in Southeastern Europe (Oradea, Novi Sad, and Sofia). Several native European parasitoids belonging to the families Encyrtidae, Eupelmidae, and Scelionidae were recorded parasitizing eggs of H. halys under field conditions, with the most common species being Anastatus bifasciatus. In addition to native parasitoids, Tr. japonicus and Tr. mitsukurii were recorded for the first time in Hungary and Oradea, respectively. Further studies are needed to explore the relationship between native and exotic species and to evaluate their impacts, which will help identify the optimal approach for utilizing these parasitoid species in managing H. halys.
