In this study, the changes in fatty acid composition of phospholipid (PL) subclasses such as phosphatidylcholine (PC), phosphatidylethanolamine (PE), phosphatidylinositol (PI), and phosphatidylserine (PS) of pre-diapausing and post-diapausing adults of sunn pest Eurygaster integriceps were investigated. Thin Layer Chromatography technique was used to separate phospholipid subclasses and Gas Chromatography equipment was used for the analysis of fatty acids. The dominant fatty acids observed in PL subclasses of E. integriceps were palmitic acid (16:0) among saturated fatty acids (SFAs), oleic acid (18:1n-9) among monounsaturated fatty acids (MUFAs) and linoleic acid (18:2n-6) among polyunsaturated fatty acids (PUFAs). It was found that the changes in fatty acid compositions from the PC, PE and PS fractions of prediapausing and postdiapausing adults were similar. In these fractions of postdiapausing adults, the percentages of 16: 0, stearic acid (18:0) and ∑SFA were lower than in prediapausing adults; however, palmitoleic acid (16: 1n-7, ∑MUFA, 18: 2n-6 and ∑PUFA were higher. The level of oleic acid in PE and PC fractions of postdiapausing individuals of the E. integriceps was determined to be significantly higher than prediapausing individuals. The ratio of unsaturated fatty acids to saturated fatty acids (UFA / SFA) in all PL subclasses of postdiapausing adults was found to be higher than those of prediapausing adults.
