Abstract: A method of exterminating a pest, including spraying a composition on the pest. The composition contains an anionic surfactant (A), a compound (B) selected from the group consisting of an organic acid and an organic acid salt, and water. The spraying is with at least one selected from the group consisting of an extrusion spray container, a trigger spray container, a push spray container, an electric sprayer, and a drone spray apparatus.

Abstract: [1] A flying pest exterminating composition which is used by spraying on flying pests, containing: a surfactant (A); at least one compound (B) selected from an organic acid and an organic acid salt; and water, in which the surfactant (A) contains at least one selected from (A1) a salt of a mono- or diester of an aliphatic alcohol having 5 or more and 18 or less carbon atoms and sulfosuccinic acid, and (A2) a mixture of a polyoxyalkylene alkyl ether (a1) and an alkyl glyceryl ether (a2), and [2] a flying pest exterminating spray including a spray container and the flying pest exterminating composition according to [1] filled in the spray container.

Abstract: The present invention relates to a flying pest exterminating spray, including a trigger spray type spray container and a flying pest exterminating composition filled in the trigger spray type spray container, in which the flying pest exterminating composition contains a surfactant (A) and water, and in the volume particle size distribution of a sprayed product of the flying pest exterminating spray measured at a position of 30 cm in terms of a horizontal distance from an injection port of the trigger spray type spray container, the proportion of the sprayed product having a particle diameter of 310 ?m or less is 70% by volume or more and 95% volume or less, the proportion of the sprayed product having a particle diameter of 354 ?m or more and 773 ?m or less is 0.05% by volume or more, and the proportion of the sprayed product having a particle diameter of 1483 ?m or more and 1926 ?m or less is 4.90% by volume or less.

Abstract: Provided is a substance inhibiting an odor caused by 2,5-dimethyl-4-hydroxy-3(2H)-furanone. An inhibitor of an odor caused by 2,5-dimethyl-4-hydroxy-3(2H)-furanone, comprising a substance inhibiting the response of an olfactory receptor OR5K1 as an active ingredient.

Abstract: It is intended to identify a substance inhibiting an odor caused by 2,5-dimethyl-4-hydroxy-3(2H)-furanone. The present invention provides a method for searching for an inhibitor of an odor caused by 2,5-dimethyl-4-hydroxy-3(2H)-furanone, comprising: adding a test substance and 2,5-dimethyl-4-hydroxy-3(2H)-furanone to an olfactory receptor OR5K1 or a polypeptide having at least 80% amino acid sequence identity thereto; measuring the response of the olfactory receptor or the polypeptide to 2,5-dimethyl-4-hydroxy-3(2H)-furanone; and identifying a test substance inhibiting the response of the olfactory receptor or the polypeptide, on the basis of the measured response.

Abstract: It is intended to provide a substance inhibiting an odor caused by sotolone. The present invention provides an inhibitor of an odor caused by sotolone, comprising an antagonist of an olfactory receptor OR8D1 as an active ingredient.
