20.500.12556/DKUM-91794 Ekologija in kompeticija tujerodnih hroščev semenarjev Megabruchidius dorsalis (Fåhræus, 1839) in Megabruchidius tonkineus (Pic, 1914) Magistrsko delo Ecology and competition in alien seed beetles Megabruchidius dorsalis (Fåhræus, 1839) and Megabruchidius tonkineus (Pic, 1914) Hrošči semenarji iz poddružine Bruchinae (Coleoptera: Chrysomelidae) vključujejo približno 1700 vrst. Megabruchidius dorsalis in M. tonkineus sta funkcionalno in ekološko zelo podobni vrsti. V Evropi se obe vrsti razvijata v trdih semenih okrasnega severnoameriškega drevesa Gleditsia triacanthos. Namen magistrskega dela je bil raziskati sobivanje hroščev v razmerah samostojnega življenja ter njihove odzive v situacijah, ko se znajdejo v medsebojni kompeticiji. Načrtovali smo dva različna laboratorijska poskusa; spremljanje razvoja obeh vrst hroščev v semenih dveh vrst gledičevk in ugotavljanje kompeticije med obema vrstama hroščev, ko se hranita s semeni trnate gledičevke. Pri obeh vrstah hroščev smo zabeležili uspešnejši razvoj na semenih zanje domorodne vrste G. sinensis. Megabruchidius tonkineus se je razvijal hitreje kot M. dorsalis ne glede na vir hrane. Prav tako je izkazal večji reproduktivni uspeh kot M. dorsalis samostojno in v sobivanju. Seed beetles from the subfamily Bruchinae (Coleoptera: Chrysomelidae) include approximately 1,700 species. Megabruchidius dorsalis and M. tonkineus are functionally and ecologically very similar species. In Europe, both species develop in the hard seeds of the ornamental North American tree Gleditsia triacanthos. The aim of this master's thesis was to investigate the co-existence of these beetles under solitary living conditions and their responses in situations of mutual competition. Two different laboratory experiments were designed: monitoring the development of both beetle species in the seeds of two Gleditsia species and studying competition between the two beetle species when feeding on the seeds of G. triacanthos. Both beetle species exhibited higher development success on the seeds of the native species G. sinensis. M. tonkineus developed faster than M. dorsalis regardless of food source and demonstrated greater reproductive success overall, including under cohabitation conditions.
