Abstract
The effects of different doses of irradiation, including gamma and electron irradiation, on viability of saw-toothed grain beetles (Oryzaephilus surinamensis) have been studied. Barley grains infested with the pests were irradiated with a GUR-120 unit in a dose range of 150–1000 Gray (Gy) (treatment at doses of 100–120 Gy/h and 1800–2000 Gy/h) and with a “Duet” electron accelerator in a dose range of 200–1000 Gy (at a dose rate of 100 Gy/imp.). It is ascertained that gamma irradiation of saw-toothed grain beetles (imago stage) in a dose range of 170–1000 Gy at a dose rate of 100Gy/h and in a dose range of 150–600 Gy at the dose rate of 1800 Gy/h results in absolute pest death 15 days after irradiation. Under electron irradiation, the absolute death of pests at the imago stage occurred 15 days after irradiation at all the studied doses and the irradiation dose rate of 100 Gy/imp. The death rate for the saw-toothed grain beetles after irradiation depended on the dose and the dose rate of irradiation. It was ascertained that, with irradiation at 250 Gy, 400–550 Gy (at a dose rate of 100 Gy/h), and 900–1400 Gy (at a dose rate of 1800 Gy/h), the pest’s death occurred 15 days, 9 days, and 6 days later, respectively. However, absolute pest death was recorded at 1200 Gy. A qualitative analysis of the irradiated spring barley grain of the Nur and Vladimir varieties was performed. Thus, gamma irradiation in a dose range of 200–600 Gy (at a dose rate of 1800 Gy/h) caused a significant increase, by 4–6%, in the ash content in the Nur variety, while a 5.3% decrease in this parameter was recorded at a dose of 800 Gy. Application of electron irradiation in the analyzed range of doses generally had no effect on the barley grain quality of the indicated variety.
