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.
当持续使用以(Z)-11-十四烯-1-基乙酸酯为唯一有效成分的通讯干扰剂 5 至 10 年时,已观察到一种现象,即其对生活在田间或类似地方的害虫(特别是蓟马科害虫)的通讯干扰效果逐代降低。因此,人们迫切希望开发出一种新的通讯干扰剂,这种干扰剂对此类田地的通讯干扰效果(对生活在田地中的害虫,特别是蓟马科害虫的连续世代干扰效果)也有所降低。本发明为防治性信息素中含有(Z)-11-十四烯-1-基乙酸酯的害虫,提供了一种含有(Z)-11-十四烯-1-基乙酸酯和除(Z)-11-十四烯-1-基乙酸酯之外的性信息素组合物中最大成分的通讯干扰剂、其中,通讯干扰剂中最大成分的重量百分比等于性信息素中最大成分的重量百分比乘以 2/100 至 50/100 范围内的一个数字所得的值。
