摘要研究了一种潜在的植物检疫处理方法来防治夏威夷地区番木瓜检疫性有害生物--白桃小食心虫，该虫为番木瓜的重要检疫害虫。对二龄若虫、未产卵的成虫和有卵的成虫进行了剂量-反应试验，以确定最耐受期。带卵的成虫是最耐受的时期。在大规模验证试验中，35,424只成年雌性鳞片在150Gy射线照射下，无论有没有卵子，都没有产生有卵子的F1代成虫。对出口番木瓜等商品上的白桃鳞片，最低吸收剂量为150GY的辐照处理应能提供检疫安全。
Abstract Irradiation was examined as a potential phytosanitary treatment to control white peach scale, Pseudaulacaspis pentagona (Targioni-Tozzetti) (Homoptera: Diaspididae), a serious quarantine pest of papaya, Carica papaya L., in Hawaii. Dose–response tests were conducted with second-stage nymphs, adult females without eggs, and adult females with eggs at a series of irradiation doses between 60 and 150 Gy to determine the most tolerant stage. The adult female with eggs was the most tolerant stage. In large-scale validation tests 35,424 adult female scales with and without eggs irradiated at a dose of 150 Gy produced no F1 generation adults with eggs. Irradiation treatment with a minimum absorbed dose of 150 Gy should provide quarantine security for white peach scale on exported papaya and other commodities.
