Abstract Chrysomya megacephala is effective in pollination of mango in Taiwan. With two years of experience, some convenient and labor saving apparatus and the procedures of mass rearing C. megacephala have been successfully developed in laboratory. Fish meal for the larvae and sugar, milk powder and yeast extract for adults are suitable in mass rearing in terms of cost and nutritional satisfaction as foods. As the pupae irradiated with 100Gy gamma ray, adult emergence was reduced. The sterile dose is 40Gy. The adults from pupae received 300Gy treatment died within one week.
摘要 大頭金蠅 (Chrysomya megacephala (Fabricius)) 為台灣芒果授粉之主要媒介昆蟲。兩年來，在試驗室大量飼養大頭金蠅，發展出價廉及簡單、易行之方法。市售飼料用魚粉，宜於飼養大頭金蠅幼蟲；蔗糖、奶粉及酵母抽出物，適於飼養成蟲。大頭金蠅蛹經40Gy加馬照射，羽化成蟲具有不孕性。經100Gy加馬照射，則成蟲之羽化率下降。經300Gy加馬照射，則羽化出之成蟲不能進食，壽命縮短為一週。
