Sažetak
Larvae of many species from the family Lucanidae feed with wood of different trees and conducted gamma irradiation on larvae of Dorcus parallelopipedus (Linnaeus 1758) had the aim to find an efficient method of wood-protection during wood-work, transport and storing. During year 2008, 62 larvae were sampled, divided into two classes considering mass and length. There were 26 larvae with an average length of 16.5 mm and mass of 355.1 mg in the first class, 36 larvae with an average length of 31.8 mm and mass of 2101.5 mg in the second class. Before the irradiation, larvae of class I were divided into 5 groups with 4 specimens each, while larvae of class II were divided into 4 groups with 8 specimens. The rest of larvae were in the control group. A standard radiotherapy unit Co-60 Alcyion Cirus (CIS Bio International) was used for gamma irradiation. Both classes of larvae were exposed to a constant dose rate of 3.6 Gy min−1 in different intervals of time, accepting doses of 360, 720, 1080, 1440 and 1800 Gy. All irradiated larvae died after 55 days from irradiation while all specimens from the control group survived. The instant lethal doses for both classes were determined: 4238.3 Gy for larvae in class I and 2784.9 Gy for class II.
