Description	In view of the antioxidant role of glutathione (GSH) and ascorbic acid (AA), we have examined capacity of the GSH-AA redox cycle in relation to oxidative stress effects in the midgut of the Colorado potato beetle Leptinotarsa decemlineata. Adult gut harbors a higher capacity to cope with oxidative stress than the larval gut, Protein carbonylation was pronounced in the wall of anterior larval midgut and was generally lower in the food digest than in the gut wall. Restriction of oxidative stress effects in anterior gut lumen manifested by lipid peroxidation and protein carbonylation is interpreted as a mechanism favoring digestion and absorption in the posterior midgut. Presence of high GSH in the posterior midgut and AA in both posterior and anterior midguts of adults points to higher utility of the GSH-AA redox system in hunting oxidative stress to manageable levels. The presence, gone expression and activity of thioredoxin reductase (TrxR) were demonstrated for the first time in L decemlineata which In view of the antioxidant role of glutathione (GSH) and ascorbic acid (AA), we have examined capacity of the GSH-AA redox cycle in relation to oxidative stress effects in the midgut of the Colorado potato beetle Leptinotarsa decemlineata.
