摘要： 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.

摘要： An improved method is proposed for the preparation of a sex pheromone dispenser used in the elimination of pest insects from the field by the disruption of mating of the insects by distributing sustained-release dispensers containing the sex pheromone compound of the insect over the field. According to the invention, pheromone dispensers made from a polyolefin-based resin and filled with the liquid pheromone are subjected, prior to distribution over the field at a relatively low temperature in early spring, to a pretreatment of keeping them at 35.degree. to 60.degree. C. until the dispenser walls of the polyolefin resin absorb 2 to 10% by weight of the pheromone. When the dispensers after the pre-treatment are distributed, a relatively high rate of pheromone release can be obtained at the low temperature as compared with untreated dispensers so that the rate of pheromone release can be relatively uniform over the whole period of the season in which the pheromone dispensers are kept over the field.

摘要： An efficient cost- and labor-saving method is proposed for controlling the population of two kinds or more of different species of insectan pests in a field by means of distributing dispensers of sex pheromone compounds for the respective species of the insects when one of the sex pheromone compounds is an unsaturated C.sub.10 to C.sub.12 alcohol and the other is an unsaturated C.sub.14 to C.sub.20 acetate or aldehyde. When these two classes of the compounds are mixed in such a proportion that the overall solubility paramater .delta. of the mixture is 9.1 to 9.7 and the mixture is contained in a dispenser body made of polyethylene or a copolymer mainly composed of ethylene moiety, the two compounds can be concurrently emitted from the dispenser in the form of vapor each at a controlled rate over a desired length of time.

摘要： Disclosed is a novel organosilicon-containing derivative of pullulan of which an organopolysiloxane moiety having a silethylene linkage is bonded to the glucose residue of pullulan through a urethane linkage. Different from conventional organopolysiloxane-modified pullulans, the inventive derivative is stable against attack of water and exhibits unique properties as a combination of the properties inherent in pullulan and in silicones. The organosilicon-containing pullulan of the invention can be easily prepared under mild reaction conditions by reacting an isocyanato group-containing organopolysiloxane with the glucosic hydroxy groups of pullulan.
