“…These results are in general agreement with data reported for a wide range of insect species (Tilton and Brower 1983) and, in particular, with data reported for some stored product moths. For instance, 350 Gy dose was reported to completely prevent egg hatch in 1-3-day-old Indian meal moth, Plodia interpunctella (Ayvaz et al 2008b) and 300 Gy dose caused a similar response in the almond moth, E. cautella (Ozyardimci et al 2006). When survival to the adult stage was used as a criterion for effectiveness, however, the effects of gamma radiation were even more severe.…”

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.

The efficacy of CO2 and N2 gases alone or in a mixture was tested against eggs, larvae, and pupae of the almond moth, Cadra cautella, a major date fruit pest, under temperature regimes of 5°C and 25°C. Our results indicated that exposing different stages to higher concentrations of CO2 significantly affected egg hatchability, larval mortality, and pupal mortality as compared to 100% N2 gas, at both temperature regimes. Application of CO2 at lower doses (below 50%) did not give 100% mortality of any developmental stage even at longer exposure timings. However, treatments at higher doses (75 and 100% CO2) were effective at 24 h and longer treatment duration. The application of 100% N2 did not effectively control C. cautella. Of all the stages, the larvae of C. cautella were most susceptible to the gases. Our results indicated that temperature has a significant effect on the efficacy of gases or their combinations tested after an exposure of 48 h and longer. Based on current findings, we conclude that CO2 gas is a good candidate for successful control of C. cautella immature stages under storage conditions and can be a potential alternative to highly toxic methyl bromide.

Food irradiation using -rays is one of powerful tools to reduce insect infestation in crops and spices. We examined the effects of -irradiation on larvae and adults of Tribolium castaneum. Eclosion for larvae was completely inhibited by irradiation at 500 Gy. A survival rate for adults was markedly reduced by irradiation at more than 500 Gy. The neutral comet assay presented that irradiation irreversibly increased DNA damage at 500 and 1000 Gy and transiently increased DNA damage at 100 Gy, suggesting possible DNA repair in larvae and adults stages. These results indicate that -irradiation at 500 Gy is available to eradicate the beetle at larval and adults stages.
