Fatty Acid Composition in Phospholipid and Triacylglycerol Fractions of Melanogryllus desertusPall. (Orthoptera: Gryllidae)

Authors: Mehmet BAŞHAN

Abstract: In this study, the fatty acid compositions in phospholipid and triacylglycerol factions of ten-day- old adults of both sexes of Melanogryllus desertusreared on stock culture medium under labora-tory conditions, and the total fatty acid composition of the stock culture medium were analysed sep-arately by gas chromatography. Quantitative analysis of both fractions and the stock culture medium showed that oleic, palmitic and linoleic acids constituted the major part of the fatty acid compositions. The fatty acid compositions of the phospholipid and triaclglycerol fractions were quantitatively different. Moreover, a polyunsaturat-ed fatty acid. linolenic acid and eicosapentaenoic acids which is the precursor of eicosanoid and prostaglandin, were determined only in the phospholipid fraction.
