Dunkelblum, E. published the artcileIdentification of sex pheromone components from pheromone gland volatiles of the tomato looper, Plusia chalcites (Especially), Formula: C14H26O2, the publication is Journal of Chemical Ecology (1987), 13(5), 991-1003, database is CAplus and MEDLINE.
The sex pheromone glands of P. chalcites released dodecyl acetate, (Z)-7-dodecenyl acetate, (Z)-9-dodecenyl acetate, 11-dodecenyl acetate, (Z)-8-tridecenyl acetate, and (Z)-9-tetradecenyl acetate. A combination of capillary gas chromatog., gas chromatog.-mass spectrometry, and di-Me disulfide derivatization enabled a rigorous identification of all these compounds, some of which were previously found in gland extracts Bioassays in a flight tunnel showed that a ternary blend of (Z)-7-dodecenyl acetate, (Z)-9-dodecenyl acetate, and (Z)-9-tetradecenyl acetate elicited directed flights from 85-100% of the males tested and elicited copulation attempts, at the end of the flights, from 44-74% of the males tested. This blend was equal in activity to the natural gland extract Addition of the other acetates had only a slight influence on the activity of this mixture Substitution of either (Z)-9-dodecenyl acetate or (Z)-9-tetradecenyl acetate in this blend by 11-dodecenyl acetate gave 2 ternary mixtures which also elicited high levels of courtship activity, almost as high as that of the original blend. Addition of (Z)-7-dodecenyl alc. inhibited almost totally the flight activity of males.
Journal of Chemical Ecology published new progress about 16974-11-1. 16974-11-1 belongs to esters-buliding-blocks, auxiliary class Aliphatic Chain, name is (Z)-Dodec-9-en-1-yl acetate, and the molecular formula is C14H26O2, Formula: C14H26O2.
