Abstract

Korisni kukci imaju ključnu ulogu u agroekosustavu, jer svojom prisutnošću pozitivno djeluju na smanjenje štetnih fitofagnih vrsta. Ostavljanjem samoniklih biljnih vrsta uz rubne dijelove poljoprivrednih površina osigurava se korisnim kukcima hrana, prostor za prezimljavanje i reprodukciju, te se njihova brojnost povećava. Cilj ovog istraživanja bio je utvrditi potencijal samoniklih biljnih vrsta u privlačenju korisnih kukaca i predložiti istraživane biljne vrste kao elemente ekološke infrastrukture. Istraživanje je provedeno tijekom dvije godine 2019. i 2020. na području općine Posedarje te je tijekom istraživanja sveukupno prikupljeno 727 primjeraka pauka i 602 primjeraka kukaca. Od ukupnog broja prikupljenih člankonožaca, 889 jedinki pripada korisnoj fauni, 238 jedinki štetnoj, a 202 jedinke su indiferentna fauna. Najveći broj korisnih jedinki člankonožaca pronađen je na biljci Helichrysum italicum (201) (Roth) G. Don, te na vrsti Foeniculum vulgare Mill. (165), a u nešto manjem broju na vrsti Hypericum perforatum L. (107) i na biljci Daucus. carota L. ssp. carota (105). Na biljnoj vrsti Lavandula angustifolia Mill. ukupno je pronađeno 96 jedinki korisnih člankonožaca, a na vrsti Dorycnium hirsutum (L.) Ser 86 jedinki. Najmanji broj korisnih člankonožaca pronađen je na vrstama Dittrichia viscosa (L.) Greuter (76) i Achillea millefolium L. (53) na kojima dominiraju pauci, red Aranea, dok su se jedinke vrsta iz porodica kukaca pojavljivale u manjem broju. Rezultati istraživanja pokazuju potencijal samoniklih biljnih vrsta u privlačenju korisnih kukaca i mogućnost korištenja onih biljnih vrsta na kojima je utvrđena najveća brojnost korisnih jedinki kao elemenata ekološke infrastrukture s ciljem jačanja biološke raznolikosti na poljoprivrednim površinama.

Abstract (english)

Beneficial insects play a key role in the agricultural ecosystem because their presence has a positive effect on the reduction in harmful phytophagous species. By leaving wild plants to grow along the boundaries of agricultural land, we provide beneficial insects with food, area in which they can land and reproduce, and their numbers therefore increase. The aim of this research was to ascertain the potential of wild plants in attracting beneficial insects and propose the inclusion of investigated plant species as elements of the ecological infrastructure. The research was conducted over the course of two years 2019. and 2020. in the area of the Posedarje municipality and in the course of the research we collected a total of 727 specimens of spiders and 602 specimens of insects. From the total number of collected arthropods, 889 units belongs to beneficial fauna, 238 units to harmful and 202 to indifferent fauna. The largest number of useful arthropods was found on the plant Helichrysum italicum (201) (Roth) G. Don, and on the species Foeniculum vulgare Mill. (165), and in a slightly smaller number on the species Hypericum perforatum L. (107) and on the plant Daucus carota L. ssp. carota (105). On the plant species Lavandula angustifolia Mill. a total of 96 specimens of useful arthropods were found, and on the species Dorycnium hirsutum (L.) Ser 86 specimens. The smallest number of useful arthropods was found on the species Dittrichia viscosa (L.) Greuter (76) and Achillea millefolium L. (53), which are dominated by spiders, the order Aranea, while individuals of species from insect families appeared in smaller numbers. The results of the research show the potential of wild plant species in attracting beneficial insects and the possibility of using those plant species on which the highest number of useful individuals has been determined as elements of ecological infrastructure with the aim of strengthening biodiversity on agricultural land.
