In Slovenia, it was first recorded in Maribor in 2017. Its presence was confirmed in 15 other European countries. In the new range, the seed beetle switched to two new hosts from North America, the honey locust (Gleditsia triacanthos) and the Kentucky coffeetree (Gymnocladus dioicus) both related to the Asian Gleditsia species. Mature G. triacanthos and Gy. dioicus seed pods were collected from the ground at locations in the central and the northeastern parts of Slovenia to investigate the presence of M. dorsalis outside the first described locations in Maribor. Seed pods were kept in bags under constant conditions in laboratory. Exit holes of seed pods and seeds typical of M. dorsalis were found at 36 locations (97%), while alive or dead M. dorsalis beetles were recorded at 26 locations (70%)Azijski hrošč semenar Megabruchidius dorsalis, ki se razvija v semenih azijskih vrst gledičevk (Gleditsia), je bil v Evropi prvič zabeležen v Italiji leta 1989, v Sloveniji pa prvič v Mariboru leta 2017. Pojavlja se še v 15 drugih evropskih državah. V novem okolju je vrsta preskočila na dva nova gostitelja iz Severne Amerike, trnato gledičevko (Gleditsia triacanthos) in rogovilarja (Gymnoladus dioicus), sicer oba sorodna azijskim vrstam gledičevke. Med našo raziskavo smo nabrali zrele stroke trnate gledičevke in rogovilarja na različnih lokacijah po osrednji in severovzhodni Sloveniji z namenom raziskati razširjenost M. dorsalis zunaj prvih opisanih lokacij v Mariboru. Stroke smo gojili v gojitvenih vrečah pod stalnimi razmerami v laboratoriju. Vrsto M. dorsalis smo potrdili v šestih krajih po Sloveniji. Na 36 lokacijah (97 %) smo našli izhodne luknje na strokih in semenih, značilne za M. dorsalis, žive ali mrtve hrošče pa smo našli na 26 lokacijah (70 %)TEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaNacionalni inštitut za biologijo
