When a communication disruptant containing (Z)-11-tetradecen-1-yl acetate as the only active ingredient is continually used for a period of 5 to 10 years, a phenomenon has been observed in which its communication-disrupting effect on insect pests, particularly of the family Tortricidae, living in the field or the like through successive generations is reduced. Accordingly, it is eagerly desired to develop a new communication disruptant which is also effective for such fields where the communication-disrupting effect (on insect pests, particularly of the family Tortricidae, living there through successive generations) has been reduced. The present invention provides, for use in the control of insect pests having (Z)-11-tetradecen-1-yl acetate contained in their sex pheromone, a communication disruptant containing (Z)-11-tetradecen-1-yl acetate and the maximum component in the composition of the sex pheromone excepting (Z)-11-tetradecen-1-yl acetate, wherein the weight percentage of the maximum component in the communication disruptant is equal to a value obtained by multiplying the weight percentage of the maximum component in the sex pheromone by a number in the range of 2/100 to 50/100.
