쌀 저장중 발생하여 가장 큰 피해를 주는 쌀바구미와 화랑곡 나방에 대한 방사선조사 구제 실험 결과, 쌀바구미의 경우 난과 유충은 0.05kGy정도의 치사선량이 요구되었으나 용(踊)과 성충은 방사선 감수성이 낮아 0.5kGy 정도였다. 화랑곡 나방의 경우 불임선량은 난에서 $0.04{\sim}0.05kGy$, 유충은 $0.05{\sim}0.06kGy$, 용(踊)은 $0.2{\sim}0.25kGy$였다. 따라서 쌀의 저장을 위한 방사선 조사는 주요 가해 해충인 쌀바구미와 화랑곡 나방을 대상으로 할 때 해충의 재오염만 방지한다면 1.0kGy 이하의 조사로서 쌀의 장기저장이 가능할 것으로 판단된다. 또한 $1.0{\sim}5.0kGy$ 조사된 현미에서의 화랑곡 나방의 서식선호성 실험에서는 방사선 조사선량에 따른 유의적 차이가 인정되지 않았다.

The effect of gamma irradiation on controlling infestation of insects on rice grain were investigated. The egg and larva stages of rice weevil (Sitophilus oryzae) were more radiosensitive than the pupal 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.
