昆虫具有一套抗氧化酶和小分子量抗氧化剂，它们可以对膳食和内源性产生的氧化剂的冲击形成级联反应。抗氧化酶如超氧化物歧化酶、过氧化氢酶、谷胱甘肽转移酶和谷胱甘肽还原酶已在昆虫中被表征。水溶性和脂溶性抗氧化剂，如抗坏血酸，谷胱甘肽，生育酚和类胡萝卜素还没有得到很好的研究，但在昆虫中可能发挥非常重要的抗氧化作用。此外，围食基质和海藻糖可能在昆虫体内具有重要的抗氧化功能。抗坏血酸的酶循环，首先在绿色植物中发现，也可能存在于昆虫中。更好地了解这些抗氧化系统可能会提供更好地了解昆虫与其宿主的生态关系。(C)1995 Wiley-Liss，Inc.
Insects possess a suite of antioxidant enzymes and small molecular weight antioxidants that may form a concatenated response to an onslaught of dietary and endogenously produced oxidants. Antioxidant enzymes such as superoxide dismutase, catalase, glutathione transferase, and glutathione reductase have been characterized in insects. Water-soluble and lipid-soluble antioxidants such as ascorbate, glutathione, tocopherols, and carotenoids have not been well studied in insects but may play very important antioxidant roles. Additionally, the peritrophic matrix and trehalose may possess important antioxidant functions in insects. The enzymatic recycling of ascorbate, first noted in green plants, may also exist in insects. A greater understanding of these antioxidant systems may provide greater understanding about the ecological relationships of insects with their hosts. (C) 1995 Wiley-Liss, Inc.
