title: Sex pheromone components of the European goat moth,Cossus cossus.
abstract: Female tip washings of the European goat moth,Cossus cossus L., were found to contain the following compounds that are structurally similar to known pheromone components of Lepidoptera (%): decyl acetate (1.5), (Z)-5-dodecenol (1), (Z)-5-dodecenyl acetate (66), dodecyl acetate (12), (Z)-5-tetradecenyl acetate (14), tetradecyl acetate (4), and hexadecyl acetate (1.5). The washes contained an average of 125 ng of (Z)-5-dodecenyl acetate per female equivalent. EAG responses to nanogram amounts of the identified products indicated that (Z)-5-dodecenyl acetate was the most potent olfactory stimulant followed by (Z)-5-tetradecenyl acetate and (Z)-5-dodecenol, whereas the saturated acetates caused only weak depolarization. A strong EAG response was also recorded for (Z)-3-decenyl acetate, which was not detected in the female tip washings. Field results showed that (Z)-5-dodecenyl acetate was essential for the attraction of the males and that (Z)-3-decenyl acetate improved the attractiveness of (Z)-5-dodecenyl acetate alone or in combination with (Z)-5-tetradecenyl acetate.
