“…Due to its weak penetrating power, however, eggs have to be treated in a very thin layer which may limit its applications, or high quality, more expensive machines are to be used. Ionizing radiation, particularly gamma radiation, has a very high penetrating ability and has been used for killing insect eggs before (Brower 1982;Tilton and Brower 1983;Toba and Burditt 1992;Mansour 2004;Ayvas and Tuncbileck 2006;Ayvaz et al 2008b). Elbadry (1965) suggested that moths eggs exposed to gamma radiation could serve as a food resource for Trichogramma rearing.…”

“…In order to determine the irradiation dose, however, the radiosensitivity of the eggs has to be investigated. Ayvas and Tuncbileck (2006) studied the effects of gamma radiation on a mixture of 1-3-day-old E. kuehniella eggs and found that 400 Gy dose (the highest used dose) reduced egg hatch to less than 27%. Because this dose did not completely stop egg hatch and eggs [2 day old are not suitable for T. cacoeciae rearing, the radiosensitivity of E. kuehniella eggs of a younger age needs to be examined.…”

The sensitivity of the Mediterranean flour moth, Ephestia kuehniella, eggs in different stages of development to gamma irradiation was studied and the acceptability of irradiated eggs by Trichogramma cacoeciae females was examined. Eggs ranging in age from 1-24 to 49-72 h were exposed, at 24 h intervals, to gamma radiation dosages ranging from 25 to 400 Gy and effects of gamma radiation on egg hatch and adult emergence was investigated. In addition, the developmental rate of immature stages (larvae and pupae), resulting from irradiated eggs, to the adult stage was examined and the acceptance of irradiated eggs to T. cacoeciae females was evaluated. Results showed that the radio-sensitivity of E. kuehniella eggs decreased with increasing age. Egg hatch in 1-24-h-old eggs was significantly affected at 25 Gy dose and at 75 Gy dose, no egg hatch was observed. When irradiating 25-48-h-old eggs, however, egg hatch was less than 5% at 100 Gy dose, and eggs 49-72-h-old were more resistant; 50 Gy had no significant effect on egg hatch and 300 Gy did not completely prevent it. Irradiation also negatively affected survival to the adult stage. When 25-48-h-old eggs were irradiated, survival to the adult stage was completely prevented at 75 Gy dose and no survival was observed beyond 100 Gy dose in 49-72-h-old eggs. In addition, the rate of development of immature stages resulting from irradiated eggs was negatively affected. While more than 97% of control moths emerged within 30 days, this ratio decreased to 53 and 69% in 1-24 and 25-48-h-old eggs exposed to 25 Gy dose. Furthermore, irradiation positively affected the degree of acceptance of eggs to parasitization; irradiated eggs (B49-h-old) were more acceptable to T. cacoeciae than cold-treated ones.

“…Dose-dependent developmental delay was also reported for the irradiated eggs and larvae of T. castaneum (Mehta et al 1990). Increasing post-treatment longevity for irradiated P. inw terpunctella, the false codling moth, Cryptophlebia leucow treta Meyrick, and the Mediterranean flour moth, Ephestia kuehniella, have been reported previously (Johnson and Vail 1988;Bloem et al 2003;Azelmat et al 2005;Ayvaz and Tuncbilek 2006). Typically, irradiated nymphs or larvae would have a prolonged nymphal or larval stage and might live longer than non-irradiated control insects (Hasan and Khan 1998).…”

“…The minimum dose required to prevent adult emergence of Plodia iterpunctella from larvae was 300 Gy, while doses required to cause death were 450 Gy and above (Azelmat et al 2005). A dose of 250 Gy was sufficient to cause complete mortality for last-instar larvae of Ephestia kuehniella Zeller (Ayvaz and Tuncbilek 2006). No codling moth larvae reached adulthood when larvae were irradiated with 200 Gy (Mansour 2003).…”

Abstract:The effect of gamma irradiation on different developmental stages of Oryzaephilus surinamensis L., was investigated. Results showed that a required dose to prevent larval emergence from irradiated 1-2-days-old eggs was 60 Gray (Gy), and 350 Gy was required to prevent adult emergence from 15-days-old larvae. Also the required dose of radiation to prevent adult emergence from irradiated 5-days-old pupa was 700 Gy. The dose of 200 Gy caused 100% mortality of irradiated adults 28 days after treatment. In addition, the effect of gamma rays was studied on the developmental stage period of each irradiated stage till adult emergence. The results revealed that there was a dose-dependent increase of the developmental periods. The growth index of adults was significantly decreased with increasing dose of radiation administered to eggs, larvae and pupae. It is recommended that doses between 600 and 700 Gy should be used to control population growth of O. surinamensis when targeting pupae and adults present in stored products.

Bu çalışmada X-ışını radyasyonun S. nonagrioides larva ve pupalarında deformasyon ve ölüm oranına etkileri incelenmiştir. AbstractIn this study, the effects of X-ray radiation were examined the rates of deformation and mortality of S. nonagrioides larvae and pupae. After exposure to radiation larvae at different doses (0-200 Gy), the rate of deformation was higher at 150 and 200 Gy (100%) than control (1.3%). Mortality was calculated 6.2% at control and 99.3% at 200 Gy. The rate of deformation at between irradiated pupae was 2.2% at control and 100% at 150 and 200 Gy; rate of mortality 8.3%, 95.8% and 100% respectively. In addition, deformation was 2.2% in control, 100% at 150 and 200 Gy in between adult emerged from pupae. Thus, the rate of deformation and mortality rise in between larvae, pupae and adult on depending dose increases and provides the possibility to lead to depletion of this population in later stages of development.
