Abstract: The present invention easily provides microcapsules by using a production method according to a more efficient and reliable interfacial polymerization method even when it is difficult to produce microcapsules by an interfacial polymerization method by adding a solution of a film-forming substance. Specifically, the present invention provides a method for producing microcapsules using two types of emulsion particles differing in size, the method comprising: an emulsion-forming step of separately forming two types of emulsions (1) and (2) whose continuous phases are common, wherein emulsion particles (1) of the emulsion (1) comprises one of two types of monomers which react with each other to form a film and emulsion particles (2) of the emulsion (2) comprises the other monomer; and a microcapsule-forming step of mixing and interfacial-polymerizing the emulsion (1) and the emulsion (2), wherein the emulsion particles (1) of the emulsion (1) have an average particle size (R) of 0.

Abstract: The present invention provides a seamless capsule for exterminating insect pests, particularly the capsule effective for termites, which hardly affects an ecological system other than the insect pests, such as a human being and domestic animals and useful insects around the human being, has an excellent safety and an excellent transporting rate by insect pests, particularly termites and has an improved exterminating efficiency per number of capsules transported or per unit time, and a method of exterminating insect pests by using the seamless capsule.

Abstract: The present invention provides an insect pest repellant and a method for repelling insect pest using the same, which is highly transported by the insect pests and which effectively exterminates insect pests and does not badly affect ecological system. The present invention is to provide an insect pest repellant comprising, in a mixed condition, (A) a dummy egg imitating an egg of an insect pest, formed from a particulate substrate on which an egg recognizing pheromone is coated, and (B) a particle containing an active component for repelling the insect pest either on a surface or in an inside of the particle.

Abstract: Provided are: a capsule for non-ferrous metal collection that can collect a non-ferrous metal; and a method for collecting a non-ferrous metal using same. The capsule for non-ferrous metal collection comprises capsule contents and a covering section covering the capsule contents, and collects a non-ferrous metal within the capsule for non-ferrous metal collection by means of the capsule for non-ferrous metal collection being immersed in a solution containing a non-ferrous metal.
