Insect pests such as yellow flower thrips (Frankliniella occidentals), green peach aphid (Myzus persica), and two-spotted spider mite (Tetranychus urticae) are known to be a problem for damaging fruit vegetables growing in plastic film house. Control of these insect pests is important in quarantine processing for export and import of fruit vegetables.
This study was conducted to determine the effects of electron beam irradiation on these insect pests and strawberry. Insect pests were irradiated with 50 ~ 5000Gy electron beam and strawberries were irradiated with 50 ~ 1000Gy. The changes of mortality, emergence rate, fecundity, and egg hatchability of electron beam irradiated insect pests were investigated. Also, changes of quality and physical sorption of free radical on electron beam irradiated strawberries were investigated.
As a result of this study, yellow flower thrips, green peach aphid and two-spotted spider mite was not directly affected by electron beam irradiation with low doses below 1kGy but the irradiation had effects on inhibition of development and reproduction of the insect pests. The strawberries with irradiated electron beam were observed relatively high rotten rate and low quality compared to those irradiated with doses below 500Gy and control. But, strawberries irradiated with 500 ~ 1000Gy were not showed any changes in quality, compared with control. Physical sorption of free radical on electron beam irradiated strawberries had no difference compared with the control. Results of this study, the technology of the electron beam irradiation is expected to be an effective control by influencing development and reproduction of insect pest for export and import of fruit vegetables.
