Phospholipid and Triacylglycerol Fatty Acid Compositions From Various Development Stages of Melanogryllus Desertus Pall. (Orthoptera: Gryllidae)

Authors: KADRİ BOZKUŞ

Abstract: Phospholipid and triacylglycerol fatty acid compositions from eggs; seventh, eighth and last nymphal stages; and 1, 20- and 40-day-old adult females of the black cricket, Melanogryllus desertus, grown in stock-culture medium under laboratory conditions were analyzed by gas chromatographic methods. A large amount of the fatty acid components at all the development stages of the insects analyzed comprised oleic, linoleic, palmitic and stearic acids. However, palmitoleic, myristic and linolenic acids were also found, at lower levels. There were fluctuations in fatty acid levels at different development stages, such as nymphs and adults. Oleic acid was lower in 1-day-old and older adults compared to nymphal stages, whereas linoleic acid was higher.
