本文报道用~(60)Co-r射线辐照进口水果作为新的检疫处理技术的探讨。初步得出的结果认为,0.15～1.20 kGy剂量的辐照处理,对芒果中的芒果实蝇Dacus occipitalis(Bezzi)老熟幼虫有杀灭效果;未被杀死的幼虫可以化蛹,但不能羽化。幼虫全部死亡或化蛹所需时间随辐照剂量的增大而缩短,最长的需40天,最短的仅需7天。本试验所用的辐照剂量均能满足检疫除害处理的要求。同时,水果营养成分分析表明,经0.60kGy和0.90kGy辐照后水果其总酸度和维生素C与对照相比无明显差异。从杀虫除害效果、卫生安全标准和降低辐照费用等方面考虑,进口芒果检疫除害处理的合理辐照剂量是0.30kGy。
This paper reports the irradiation of imported fruits with ~ (60) Co-r rays as a new quarantine treatment technology. Preliminary results suggest that radiation treatments at doses of 0.15-1.20 kGy have a killing effect on mature larvae of Dacus occipitalis (Bezzi) in mango fruit; the un-killed larvae can pupate, but can not emerge . The larvae die or pupation time required for irradiation dose shorten, the longest need 40 days, the shortest only 7 days. The radiation dose used in this experiment can meet the requirements of quarantine and pest control. At the same time, the analysis of nutritional components of fruits showed that the total acidity and vitamin C of fruits after 0.60kGy and 0.90kGy irradiation had no significant difference compared with the control. Considering insecticide and pest control effects, sanitation and safety standards, and reduction of irradiation costs, a reasonable irradiation dose for imported mango quarantine and pest elimination treatment is 0.30 kGy.
