20.500.12556/DKUM-88734 Tujerodni invazivni hrošč semenar Megabruchidius dorsalis (Chrysomelidae) živi v Sloveniji The alien invasive seed beetle Megabruchidius dorsalis (Chrysomelidae) established in Slovenia 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 %). The Asian seed beetle Megabruchidius dorsalis, which develops inside the seeds of native Gleditsia species, was first recorded in Europe in Italy in 1989. 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%). tujerodne vrste trnata gledičevka bioinvazije bioinvasions alien species Coleoptera Bruchinae Gleditsia triacanthos Gymnocladus dioicus true true true University of Ljubljana Press Slovenski jezik Angleški jezik Znanstveno delo 2024-05-22 03:32:57 2024-09-27 11:48:08 2025-02-05 09:48:06 0000-00-00 00:00:00 2022 0 0 str. 5-16 št. 1 Letn. 24 2022 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 2021-11-28 2022-06-13 595.76 122022147 1580-0814 RAZ_Horvat_Eva_2022.pdf RAZ_Horvat_Eva_2022.pdf 1 F1814BD8CDDC6A1329824EAEA3632EAF d2ab86574b29c688a1d4761084650c52be3590a2c9472befa95108287eff7848 2ae13498-7cb5-11ef-b866-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=185968 https://doi.org/10.14720/ns.24.1.5-16 0 427ad432-7cb5-11ef-b866-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=185969 Fakulteta za naravoslovje in matematiko 0 0 0
