ABSTRACT:
A bag-like dispenser is proposed which contains a sex pheromone compound of insects and is used for sustainedly releasing the pheromone compound at a uniform emission rate over a long period of time so as to exhibit effectiveness for the population control of pests by distributing a number of the dispensers over fields. The bag-like dispenser body is formed of a specific polymeric laminate film having a thickness of 20-200 .mu.m and composed of at least two layers or, preferably, of three layers, in which one of the layers is a film of a polymer or copolymer of vinylidene chloride having a thickness of 4-20 .mu.m as the intermediate layer of the three-layered laminate and the other layer or each of the other layers is a film of a specific polymer having a specified thickness, such as a film of a polyolefin, copolymer of ethylene and vinyl acetate, poly(vinyl chloride), copolymer of vinyl chloride and vinyl acetate and the like.
