Insect tissues, not microorganisms, produce linoleic acid in the house cricket and the American cockroach.
Biosynthesis of linoleic acid, 18:2 (n-6), was unambiguously demonstrated to occur in the cockroach, Periplaneta americana, and the cricket, Acheta domesticus. Axenic tissue from both of these insect species was demonstrated by radio-gas-liquid chromatography (radio-GLC) and radio-high-performance liquid chromatography (radio-HPLC) to incorporate [1-14C]acetate and [1-14C]oleate into this essential fatty acid.
