| Abstract: | "The main component of the sex pheromone precursor in females of Macrodiprion nemoralis was identified as a threo-3,7, 9-trimethyl-2-tridecanol isomer, approximately 800 pg per female, by gas chromatography-mass spectrometry. Comparison of mass spectrometric ion chromatograms showed that the natural compound in the female extract has the same retention time and mass spectrum as one of the two synthetic threo peaks. The acetate of the synthetic 16-isomer mixture caught a large number of males in the field, confirming the structure of the active pheromone. Comparison of gas chromatograms of the natural female extract with the eight synthetic threo stereoisomers showed that the pheromone is the (2S,3R,7R, 9S)-stereoisomer of 3,7,9-trimethyl-2-tridecyl acetate" |
