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.

摘要

不同剂量的辐照,包括伽马射线和电子辐照,对锯齿状甲虫(Oryzaephilus surinamensis)活力的影响)已被研究。用GUR-120装置以150–1000 Gray(Gy)的剂量范围照射受害虫侵染的大麦籽粒(以100–120 Gy / h和1800–2000 Gy / h的剂量进行辐照)和“ Duet”辐照。电子加速器,剂量范围为200–1000 Gy(剂量率为100 Gy / imp。)。可以确定,在170–1000 Gy的剂量范围内以100Gy / h的剂量率和在150–600 Gy的剂量范围内以1800 Gy的剂量对锯齿状甲虫进行γ射线辐照/ h导致辐射后15天绝对有害生物死亡。在电子辐照下,在所有研究剂量和辐照剂量率为100 Gy / imp的辐照后15天,成虫阶段的有害生物绝对死亡。辐照后的锯齿状甲虫的死亡率取决于辐照的剂量和剂量率。可以确定的是,以250 Gy,400–550 Gy(100 Gy / h的剂量率)和900–1400 Gy(1800 Gy / h的剂量率)照射时,害虫的死亡发生了15天,分别在9天和6天后。但是,记录的绝对害虫死亡为1200 Gy。对Nur和Vladimir品种的春季大麦籽粒进行了定性分析。因此,在200–600 Gy的剂量范围内(以1800 Gy / h的剂量率)进行的γ射线辐照会导致Nur品种的灰分含量显着增加4–6%,而Nur品种的灰分减少5.3%。以800 Gy的剂量记录该参数。在所分析的剂量范围内应用电子辐照通常对所示品种的大麦籽粒品质没有影响。在900和1400 Gy(剂量为1800 Gy / h)下,害虫的死亡分别在15天,9天和6天后发生。但是,记录的绝对害虫死亡为1200 Gy。对Nur和Vladimir品种的春季大麦籽粒进行了定性分析。因此,在200–600 Gy的剂量范围内(以1800 Gy / h的剂量率)进行的γ射线辐照会导致Nur品种的灰分含量显着增加4–6%,而Nur品种的灰分减少5.3%。以800 Gy的剂量记录该参数。在所分析的剂量范围内应用电子辐照通常对所示品种的大麦籽粒品质没有影响。在900和1400 Gy(剂量为1800 Gy / h)下,害虫的死亡分别在15天,9天和6天后发生。但是,记录的绝对害虫死亡为1200 Gy。对Nur和Vladimir品种的春季大麦籽粒进行了定性分析。因此,在200–600 Gy的剂量范围内(以1800 Gy / h的剂量率)进行的γ射线辐照会导致Nur品种的灰分含量显着增加4–6%,而Nur品种的灰分减少5.3%。以800 Gy的剂量记录该参数。在所分析的剂量范围内应用电子辐照通常对所示品种的大麦籽粒品质没有影响。对Nur和Vladimir品种的春季大麦籽粒进行了定性分析。因此,在200–600 Gy的剂量范围内(以1800 Gy / h的剂量率)进行的γ射线辐照会导致Nur品种的灰分含量显着增加4–6%,而Nur品种的灰分减少5.3%。以800 Gy的剂量记录该参数。在所分析的剂量范围内应用电子辐照通常对所示品种的大麦籽粒品质没有影响。对Nur和Vladimir品种的春季大麦籽粒进行了定性分析。因此,在200–600 Gy的剂量范围内(以1800 Gy / h的剂量率)进行的γ射线辐照会导致Nur品种的灰分含量显着增加4–6%,而Nur品种的灰分减少5.3%。以800 Gy的剂量记录该参数。在所分析的剂量范围内应用电子辐照通常对所示品种的大麦籽粒品质没有影响。
