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： Unreacted monomer or monomers and any other volatile organic compounds contained in an aqueous dispersion of polymerizate are removed or separated by a method comprising circulating the aqueous polymerizate dispersion from the bottom of its container to the upper part of the container located over the surface of the dispersion via an exterior conduit. The pressure in the container is maintained at a level reduced to about the saturated vapor pressure of water at the temperature of the dispersion. This manner of separation of monomer from polymer serves to improve the working environment as well as the resulting polymer quality, and the monomer or monomers thus recoverd can be advantageously recycled.

摘要： In the technology of population control of lepidopteral insects as an agricultural or horticultural pest, such as tomato pinworms, by distributing dispensers of sex pheromone of the species over the field, an unexpected discovery has been made that, to the contrary to the general understanding for the effectiveness of the E-isomer of the pheromone compound, e.g., 4-tridecenyl acetate, a rather higher activity can be obtained by using a mixture of the E-isomer and Z-isomer in a mixing proportion of 1:1 to 3:1 than the E-isomer in a high purity.
