Strawberry ( Duch) is one of the representative fresh agricultural products exported overseas from South Korea. The greenhouse whitefly (Hemiptera: Aleyrodidae), , is an economically important insect pest of commercial strawberries in South Korea. The objective of the present study was to evaluate the effects of electron beam and X-ray on the development and reproduction of . To determine the radiation dose as a quarantine treatment for strawberry, T. vaporariorum were placed at the top, middle, and bottom location in boxes filled with strawberry fruits and irradiated. Eggs were completely inhibited from hatching at 50 Gy, and adult emergence of 3rd nymphs was completely suppressed at 150 Gy in both electron beam and X-ray. Some adults spawning occurred at 100 Gy. However, F hatchability was completely suppressed. The results suggest that was the most radiotolerant to both of ionization energy at the nymph stage. The dosimetry results showed that the penetrating power of ionizing radiation in boxes filled with strawberry fruits was the lowest at the bottom location. A treatment dose of 150 Gy is adaptable as a quarantine treatment to T. vaporariorum nymph in strawberry fruit. Our results indicate that ionizing radiation could be recommendable as a phytosanitary treatment for quarantine.
草莓（达奇品种）是韩国出口到海外的代表性新鲜农产品之一。温室白粉虱（半翅目：粉虱科）是韩国商业草莓上一种具有重要经济意义的害虫。本研究的目的是评估电子束和X射线对温室白粉虱发育和繁殖的影响。为了确定作为草莓检疫处理的辐射剂量，将温室白粉虱放置在装满草莓果实的盒子的顶部、中部和底部位置并进行辐照。在电子束和X射线处理中，50 Gy时卵完全抑制孵化，150 Gy时第三龄若虫的成虫羽化完全被抑制。在100 Gy时有一些成虫产卵。然而，F代孵化率完全被抑制。结果表明，在若虫阶段，温室白粉虱对两种电离能量的耐受性最强。剂量测定结果表明，在装满草莓果实的盒子中，电离辐射在底部位置的穿透能力最低。150 Gy的处理剂量适合作为草莓果实中温室白粉虱若虫的检疫处理。我们的结果表明，电离辐射可推荐作为一种植物检疫处理方法。
