Monitoring of Epigean Beetles from the Grassland Located in Bilbor, Harghita County

Abstract

Barber traps were used to monitor the coleopteran fauna of grasslands in the Bilbor area. In 2017, 268 specimens were collected using Barber traps. They belong to 55 species, systematically classified in 13 families. Of the total catches, 58.2% are represented by phytophagous beetles and 41.8% of them are predatory beetles. Most catches belong to the Carabidae family, with 75 specimens represented by 14 species. Most of the specimens caught belong to the species Carabus ulrichii Germar. In 2018, 305 copies were collected. They belong to 56 species, systematically classified in 13 families. This year too, most catches belong to the Carabidae family, which means 25.9% of the total catches. Most of the captured specimens belong to the species Harpalus tardus Panz. In the two years, 573 beetles, belonging to 65 species, were captured. Of the species reported, 31 are phytophagous species and 34 are zoophagous. According to the Ecological Significance Index (W) 5 species are accessory with the value of the index between 1.1-5.0% (Carabus ulrichii Germar, Harpalus distinguendus Duft., Ips amitinus Eichh., Ips typographus L. and Olibrus affinis Sturm.).
