Sex gland extracts and washes of E. ambiguella contained 10-20 ng/female of the primary sex pheromone component Z-9-dodecenyl acetate (Z9-12:Ac), accompanied by a number of related compounds These are (E9-12:Ac), Z-9-dodecen-1-ol (Z9-12:OH), saturated acetates of 12, 16, 18, and 20 Cs, and traces of a doubly unsaturated acetate, tentatively identified as a 9,11-dodecadienyl acetate. Octadecyl acetate (18:Ac) predominated among the pheromone-related components, making up 1-2, occasionally 20-30-fold the amount of Z9-12:Ac. The same compounds were also found in field-collected females and in effluvia. Z-9-Undecenyl acetate, which is a male attractant on its own, was also found in a sample of female effluvia. A hierarchy in the ethol. function of the pheromone components was observed Z9-12:Ac was an attractant for E. ambiguella males. Dodecyl acetate (12:Ac) was not attractant on its own, but augmented male catch when added to the main attractant. Addition of 18:Ac augmented attraction only when both Z9-12:Ac and 12:Ac were present. Wind-tunnel tests demonstrated that 18:Ac also raised the disorientation threshold, as previously shown for 12:Ac. Other compounds, with the possible exception of addnl. saturated acetates, had either no effect on trap catch or, in the case of E9-12:Ac, Z9-12:OH, and E-9,11-dodecadienyl acetate, were inhibitory above a certain level. A blend of roughly equal parts of Z9-12:Ac, 12:Ac, and 18:Ac provided the best blend for E. ambiguella known to date. This study involved multiple reactions and reactants, such as (E)-Dodeca-9,11-dien-1-yl acetate (cas: 50767-78-7Computed Properties of C14H24O2).
(E)-Dodeca-9,11-dien-1-yl acetate (cas: 50767-78-7) belongs to esters. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. Esterification is the general name for a chemical reaction in which two reactants (typically an alcohol and an acid) form an ester as the reaction product. Esters are common in organic chemistry and biological materials.Computed Properties of C14H24O2
