The reproductive tracts (testes, seminal vesicles, accessory glands, ejaculatory duct) of male house crickets ( Acheta domesticus ) and field crickets ( Gryllus spp.) contain ca. 6% of eicosa‐5,11,14‐trienoate in total tissue fatty acids. This fatty acid is concentrated primarily in the phosphatidylcholine fraction of phospholipids (12.6%) and occurs in no more than trace amounts (<0.1%) in neutral lipids. The 18∶1 fatty acid fraction of total tissue lipid fatty acids consisted of 2 isomers with unsaturation in the Δ5 and Δ9 positions in proportions of ca. 33 and 67 mol %, respectively.
