The sex pheromone of Scrobipalpula absoluta (Meyrick) (Lepidoptera: Ge
lechiidae) was identified as a 92:8 mixture of (3E,8Z 11Z)-3,8,11-tetr
adecatrienyl acetate (1) and (3E,8Z)-3,8-tetradecadienyl acetate (2) t
hrough mass spectrometric investigation of the dimethyl disulphide der
ivatives of excised sex pheromone glands. It is the first time that th
is method was used for triple unsaturated straight chain molecules. Co
mpound (2) was identified as a new pheromone component. A synthetic mi
xture of the two identified compounds proved to be attractive in wind
tunnel experiments.
