Platynota idaeusalis

The fatty acid content of the ovipositor tips of a variety of Lepidopteran species were determined by acid methanolysis followed by gas-liquid chromatography (GLC) (4.). In each case, unusual fatty acids corresponding to pheromone components were identified. For example, the tufted apple bud moth, Platynota idaeusalis, uses (E)—11—tetradecenyl acetate and alcohol as pheromone components (5.) and also contains (E) -11—tetradecenoic acid in its ovipositor tip. In several species, the fatty acid content of the rest of the insect also was determined. In each instance, the unusual fatty acid components were found only in the ovipositor tip or in the pheromone-producing gland located in the tip.
