Comparison of total lipid and fatty acid compositions of whole-body and body segments of lertha extensa adults (Neuroptera: Nemopteridae)
(2009) Cakmak O.; Bashan M.; Satar A.
Total lipid and fatty acid compositions of phospholipids and triacylglycerols fractions, prepared from whole body and selected body segments (head, thorax and abdomen) of adults males and females of Lertha externa Oliver (Neuroptera: Nemopteridae), were analyzed by gas chromatography and gas chromatography-mass spectrometry. The female abdomen has the highest level of total lipid in body segments. Predominant fatty acid components of phospholipid and triacylglycerol fractions in the whole body and three body segments were Cl6:0, C18:ln-9 and C18:2n-6 acids, comprising more than 80 % of the fatty acid components. Fatty acid profiles of whole body extracts differed by sex only for phospholipid and triacylglycerol fractions. Fatty acid profiles of phospholipids from the head and abdomen were similar to those of the whole body, but considerably different from that of thorax. Several minor fatty acids, comprising < 2% of the total, were noted. Detailed profiles are reported, and are compared to those of other insects.
