Uncommon C18 Conjugated Dienes Define the Sex Pheromone System of <i>Thelosia camina</i> (Lepidoptera: Apatelodidae), a Pest of Yerba Mate.

ABSTRACT: The yerba mate tree Ilex paraguariensis is widely consumed in South America, and the limited recommendation for pesticide use highlights the need for alternative pest-management strategies. Thelosia camina is an important defoliator whose damage severely reduces yields. This study investigated the sex-pheromone system of T. camina as a basis for pheromone-mediated control. Female pheromone glands were extracted and analyzed by gas chromatography-electroantennographic detection, revealing nine antennally active compounds. Structural elucidation identified three major components (13Z,15Z)-octadeca-13,15-dienal (4), (13Z,15Z)-octadeca-13,15-dien-1-ol (5) and (13Z,15Z)-octadeca-13,15-dien-1-yl acetate (9). Rema
