Communication disruptant and communication disruption method

A method for the control of an insect pest of the family Tortricidae comprising the steps of:

• identifying the insect pest to be controlled, wherein the natural sex pheromone of said insect pest contains (Z)-11-tetradecen-1-yl acetate;
• obtaining a communication disruptant composition consisting essentially of (Z)-11-tetradecen-1-yl acetate and a second component found in the natural sex pheromone of said insect pest, wherein said second component is the component found in highest concentration in the natural sex pheromone other than (Z)-11-tetradecen-1-yl acetate, and further wherein the weight percentage of said second component in the communication disruptant composition is equal to a value obtained by multiplying the weight percentage of said second component in the natural sex pheromone by a number in the range of about 0.14 to 0.5 wherein the second component is (E)-11-tetradecen-1-yl acetate and said insect pest is Archips breviplicana;
• and,
• exposing said insect pest to said communication disruptant.

• and,
• exposing said insect pest to said communication disruptant;
• wherein the second component is (E)-11-tetradecen-1-yl acetate and said insect pest is a member of the group consisting of Archips podana, Choristoneura rosaceana and Argyrotaenia velutinana.
