Seasonal changes in minor membrane phospholipid classes, sterols and tocopherols in overwintering insect, Pyrrhocoris apterus

Popis výsledku v původním jazyce

In this paper we extend the scope of lipid analysis and bring results on seasonal changes in minor phospholipid classes, lysophosopholipids (LPLs), free fatty acids, phytosterols and tocopherols in heteropteran insect, Pyrrhocoris apterus. We found thatmuscle tissue contains unusually high amounts of LPLs. Muscle and fat body tissues also contain high amounts of ?-sitosterol and campesterol, two phytosterols derived from plant food, while only small amounts of cholesterol are present. In addition, twoisomers (? and ?) of tocopherol (vitamin E) are present in quantities comparable to, or even higher than phytosterols in both tissues. Distinct seasonal patterns of sterol and tocopherol concentrations were observed showing a minimum in reproductively active bugs in summer and a maximum in diapausing, cold-acclimated bugs in winter. Possible adaptive meanings of such changes are discussed.
