Abstract

This study investigated the effects of UV-C irradiation on the mortality, reproduction, wing morphology, and antioxidant responses of Tribolium castaneum, an important pest in stored products. Observations made 10 days after irradiation revealed that eggs exposed to 15 min of irradiation exhibited a 100 % mortality. Larvae required 120 min of irradiation to reach a 100 % mortality rate, while pupae exposed for 60 min resulted in a 100 % mortality. However, no significant increase in mortality was observed among adults subjected to different irradiation durations, although their reproductive capacity appeared to be impacted. Morphological analysis revealed wing deformities and abnormal venation in irradiated pupae, associated with the dysregulation of critical wing development genes, including Sob, vg, and Cht-7. Furthermore, UV-C exposure boosted the activities of antioxidant enzymes, such as superoxide dismutase (SOD) and peroxidase (POD), alleviating oxidative stress. These findings highlighted the effects of UV-C irradiation on insect physiology, offering a theoretical basis for its use in sustainable pest management strategies.

UV-C辐照对木栗生长和抗氧化反应的影响

研究了UV-C辐照对贮藏产品中重要害虫castaneum的死亡率、繁殖、翅形态及抗氧化反应的影响。辐照后10天的观察显示，暴露于15分钟辐照下的卵死亡率为100%。幼虫照射120分钟死亡率达到100%，蛹照射60分钟死亡率达到100%。然而，在接受不同照射时间的成年人中，死亡率没有显著增加，尽管他们的生殖能力似乎受到了影响。形态学分析显示，辐照后的蛹出现了翅膀畸形和异常的脉络，这与关键的翅膀发育基因（包括Sob、vg和Cht-7）的失调有关。此外，UV-C暴露提高了抗氧化酶的活性，如超氧化物歧化酶（SOD）和过氧化物酶（POD），减轻氧化应激。这些发现突出了UV-C照射对昆虫生理的影响，为其在害虫可持续治理策略中的应用提供了理论依据。

期刊介绍： The Journal of Stored Products Research provides an international medium for the publication of both reviews and original results from laboratory and field studies on the preservation and safety of stored products, notably food stocks, covering storage-related problems from the producer through the supply chain to the consumer. Stored products are characterised by having relatively low moisture content and include raw and semi-processed foods, animal feedstuffs, and a range of other durable items, including materials such as clothing or museum artefacts.
