摘要: Analysis of female abdominal tips ofAgrotis segetum by means GC-MS showed the presence 13 aliphatic acetates and alcohols. (Z)-7-Dodecenyl acetate was found to be main component in extracts at amounts about 1 ng/female. (Z)-9-Tetradecenyl (Z)-7-dodecenol were present extent 49 19%, respectively, component. Minor components could identified as decyl acetate, (Z)-5-decenyl dodecyl (Z)-9-dodecenyl tetradecyl a tetradecenyl hexadecyl hexadecenyl (Z)-5-decenol, (Z)-9-tetradecenol. The biological activity (Z)-7-dodecenyl detected GC-EAD. Tested EAG evoked highest response among pheromone candidates, followed (E)-5-decenyl acetate. Single-cell recordings from 100 male antennal sensilla trichodea revealed receptorcells highly sensitive (Z)-5-decenyl, (Z)-7-dodecenyl, (Z)-8-dodecenyl, (Z)-9-tetradecenyl well (Z)-5-decenol. receptors activated significantly also extracts. When tested tube olfactometer, blend decyl, same did glands.
