説明

Sex pheromone of the semi-looper, Autographa nigrisigna, was extracted from abdominal tips of virgin females. The crude extract was purified by Florisil column chromatography. The pheromonal activity of samples was evaluated in a flight tunnel. (Z)-5-, (Z)-7-, (E)-7-, 11-Dodecenyl acetates, (Z)-7-dodecenol and (Z)-7-tetradecenyl acetate were identified in the virgin female extract through analysis by capillary GC and GC-MS. A rubber septum loaded with 1.68 mg of a mixture of the (Z)-5-, (Z)-7-dodecenyl acetates, (Z)-7-dodecenol and (Z)-7-tetradecenyl acetate in a ratio of 100:2:62:4 attracted male moths under field conditions. These 4 compounds were therefore determined to be the sex pheromone components of A. nigrisigna.
