摘　　要：采用（６０）ＣＯ－γ射线１００、２００、３００、４０ＧＹ辐照结合低温冷藏处理柑桔和柚内的柑桔大实蝇幼虫，结果表明，用（６０）ＣＯ—γ射线辐照柑桔大实蝇幼虫，结合低温（３～６℃）处理，２１，２８，３５天可以明显地提高幼虫死亡率。对照幼虫，经冷藏处理３５天后，死亡率仅为５５．４％。经３００ＧＹ以下剂量辐照的幼虫，在低温（３～６℃）下，仍能继续发育，化蛹，但化蛹速率比对照显著降低。不同剂量辐照处理的幼虫，经不同时间的冷藏处理，最终死亡率可达１００％。试验证明，用４０ＧＹ的射线辐照，再经３～６℃的低温冷藏２８天以上，柑桔大实蝇幼虫死亡率即可达１００％，符合检疫处理要求。This paper reported the effects of (60)Co-γ rays combined with low temperture storage as a quarantine treatment for sweet orange infested with Tetrasdacus citri.The results showed that the gamma irradiation combined with low-temperture storage(3￣6℃) could extremely raise the death-rate of larvae.Irradiated at doeses up to 400GY,and stored 3￣ 6℃,the death-rate of larvae was 100%.The death-rate of larvae with no irradiation and stored for 35 days at low-temperature(CK) was 55.4%.Irradiated with below doeses of 300Gy,the larvae could still develop into pupa,but the pupation-rates were lower.The final death-rates of larvae irradiated with different doeses and stored at low-temperature were 100%.
