摘　　要：番石榴实蝇(Bactrocera correcta(Bezzi))起源于南亚,是一种为害热带、亚热带水果和蔬菜的重要害虫,极易随寄主果实人为传播。为了寻求一种对该虫高效、安全的除害处理技术,本文应用钴60(60Co)对感染番石榴实蝇的番石榴果实进行辐照处理。结果表明:阻止番石榴实蝇达到机率值9的致死剂量LD99.9968为125.54(101.23～167.52)Gy,采用113Gy处理69 118头番石榴实蝇3龄幼虫,没有成虫羽化。该剂量可以作为检疫除害处理的参考指标。The origin of Bactrocera correcta （Bezzi） is from south of Asia. It is an important pest of semitropical fruits and vegetable. It is spread easily by host fruits. For researching the safely effective treatment, we applied ^60Co irradiation quarantine treatment for guava which were infested Bactrocera correcta （ Bezzi）, guava fruit fly. The result showed dose of LD99.9968 of guava fruit fly is 125.54（ 101.23 -- 167.52） Gy, doses 113Gy applied to 69 118 3^rd larvae, also resulted in no survival to the adult stage. So this doses may be the referenced index of quaran- tine treatment to guava fruit fly.
