应用０．１０～０．４０ｋＧｙ的６０Ｃｏγ－射线对新鲜荔枝果实中的蒂蛀虫（ＣｏｎｏｐｏｍｏｒｐｈａｓｉｎｅｎｓｉｓＢｒａｄｌｅｙ）幼虫进行辐射检疫处理研究判断辐照检疫处理的有效性是基于处理幼虫不能羽化为成虫作为标准概率分析结果表明，致使荔枝蒂蛀虫幼虫９９５％死亡的辐照剂量是０２５４ｋＧｙ，９５％置信区间是０２２０－０２８９ｋＧｙ，辐照处理与低温（７℃）冷藏相结合，可提高荔枝蒂蛀虫的死亡率．对荔枝果实的营养成分分析结果表明，经０２０、０２５、０３０ｋＧｙ辐照处理与对照组之间，其还原糖和维生素Ｃ含量无明显差异，而总酸度含量、贮藏期间坏果率则处理组比对照低６０Ｃｏγ－射线既能杀死荔枝蒂蛀虫幼虫，达到检疫处理的目的，又有利于果实贮藏保鲜

Radiation quarantine treatment of Conopomorphas sinensis Bradley larvae in fresh litchi fruit using 60Co γ-ray of 0.10-0.40 kGy  To judge the effectiveness of irradiation quarantine treatment is based on the probability that larvae can not become adults as adults The results showed that irradiation dose of 0254kGy and 95% confidence interval of 0220 ~ 0289kGy resulted in 995% mortality of litchi stalk larvae. Irradiation combined with cold storage at 7 ℃ Increase the mortality rate of litchi pedicels. Analysis of the nutritional components of the litchi fruit showed that there was no significant difference in the content of reducing sugar and vitamin C between 020,025,030kGy irradiation and the control group, while the total acidity, Fruit rate is lower than the control group  60Coγ-rays can kill lychee insect borers, to quarantine treatment purposes, but also conducive to fruit storage and preservation 
