Description

Composition for expelling flying insect Technical Field The present invention relates to a composition for expelling flying insect pests and a spray for expelling flying insect pests. Background Insect pests such as mosquitoes and flies are factors that cause infectious diseases or dermatitis in animals such as humans by being mediated by pathogens. In particular, a part of mosquitoes transmit pathogens such as dengue fever, zkafever, yellow fever, encephalitis, malaria, etc., and thus are very hygienically harmful pests. In the prior art, in order to protect the body from such flying pests, a method of spraying insecticide is generally employed. However, there is a comparative concern about the safety of the insecticidal component contained in the insecticide to the human body. In particular, it is desirable to apply a safe insecticide to young children who are easily bitten by mosquitoes. In addition, although the prevention of biting by insects outdoors has been mainly studied in the prior art, recent studies have revealed that the frequency of biting by mosquitoes is the same as or higher than that outdoors even indoors. Therefore, it is desired to provide a means for protecting the body from flying pests even indoors. As a method for capturing and repelling flying pests without using an insecticidal component, for example, japanese patent laid-open No. 2012-97004 (patent document 1) discloses a pest repellent and a pest repellent formulation which are aqueous liquids containing an alkyl (meth) acrylate copolymer having a film-forming ability and a surfactant, and which can obtain a pest repellent effect even if the insecticidal component is not contained. Japanese patent publication No. 2011-516484 (patent document 2) discloses a harmful biocide composition comprising a harmful biocide and an adjuvant, which imparts a synergistic kill rate. Disclosure of Invention The present invention relates to a composition for controlling flying pests, which is sprayed on flying pests and contains a surfactant (A), a compound (B) selected from at least one of an organic acid and an organic acid salt, and water, The surfactant (A) contains at least one selected from the group consisting of a salt (A1) of a monoester or diester of an aliphatic alcohol having 5 to 18 carbon atoms and sulfosuccinic acid, and a mixture (A2) of a polyoxyalkylene alkyl ether (A1) and an alkyl glyceryl ether (A2). Drawings Fig. 1 is an explanatory view of a method for evaluating the insecticidal properties of flying insects, which is a schematic plan view of a frame (1) in which mosquitoes used for evaluation are enclosed. Fig. 2 is an explanatory view of a method for evaluating the insecticidal properties of flying insects, which is a schematic view of the case where the composition for expelling flying insects is sprayed in the frame (1) as seen from the side surface direction of the frame (1). Detailed Description The pest repellent of patent document 1 has a pest repellent effect by containing a (meth) acrylic acid alkyl ester copolymer having a film forming ability to reduce the flexibility of wings of flying pests when sprayed on the flying pests, to lose the flying ability, or to form a film blocking a valve or an air duct to suffocate the pests. However, since the type of insect repellent sprayed on flying insects needs to be adjusted to a viscosity suitable for spraying, the amount of the polymer to be added as an active ingredient of the insect repellent is substantially limited. Patent document 2 describes spraying a composition containing a harmful biocide and an adjuvant to insects, but a method of spraying a composition containing a harmful biocide as an insecticidal component is not a preferable method from the viewpoint of human safety. For the above reasons, it is desired to develop a composition which is highly safe to the human body and the environment and has improved insecticidal properties for a type of insect repellent sprayed on flying insects. The present invention relates to a composition for controlling flying insect pests, which is sprayed on flying insect pests for use, has high safety to the human body and the environment, and has improved insecticidal properties, and a spray for controlling flying insect pests. The present inventors have found that, in a composition for controlling flying pests by spraying the composition onto the flying pests, the composition contains a surfactant (A) containing at least one member selected from the group consisting of a salt (A1) of a monoester or diester of an aliphatic alcohol having 5 or more and 18 or less carbon atoms and sulfosuccinic acid and a mixture (A2) of a polyoxyalkylene alkyl ether and an alkyl glyceryl ether, and the flying ability of the flying pests can be reduced when the composition is sprayed onto the flying pests. Further, it has been found that by containing the compound (B) selected from at least one of an organic acid and an organic acid salt in the
