곡류의 해충 구제를 위한 감마선의 이용 = Control of Insects on Stored Rice Grain by Gamma Irradiation

다국어 초록 (Multilingual Abstract)

The effect of gamma irradiation on controlling infestation of insects on rice grain v-ere investigated. The egg and larva stages of rice weevil (Sitophilus oryzae) were more radiosensitive than the papal and adult stages. The complete mortal dose of the first two stages was 0.05kGy, while it was 0.5kGy in the. second two stages. In Indian-meal moth, (plodia interpuctella Hubner), sterile doses of egg, larva, pupa and adult were 0.04 to 0.05, 0.05 to 0.06 and 0.2 to 0.25kGy, respectively, Therefore, the irradiation dose within 1.0kGy was considered to be effective for rice storage so far as reinfestation was prevented. Attractiveness of Indian-meal moth toward the rice irradiated at 1.0 to 5.0kGy was non-significant in F-test.
