Pheromone biosynthesis

WebJul 29, 2003 · Pheromone biosynthesis-activating neuropeptide (PBAN), a peptide produced by the subesophageal ganglion, is used by a variety of moths to regulate pheromone production. PBAN acts directly on pheromone gland cells by using calcium and cAMP as second messengers. WebPheromone components for many lepidopteran species are produced by the use of unique chain-shortening and Δ9, Δ10, and Δ11 desaturase systems. Correlations in the Tortricidae indicate that the pheromone components derived from Δ9 and Δ01 desaturases are found in the more primitive species (those possessing morphological plesiomorphies). The …
