Description

  The present invention relates to a pest control agent, a method for controlling the pest using the agent, and a food material used in the method. More specifically, the present invention relates to a pest control agent produced through a step in which a cyclic oligosaccharide and an insecticide are brought into contact with each other through a solvent, the industrial material pest control method using the agent, and the method It is related with the foodstuff used for.

  Industrial materials such as wooden materials and synthetic resins are used in large quantities in buildings, materials such as houses, bridges and wooden playground equipment, and materials (including outdoor materials and indoor materials). As a result of such an industrial material being damaged by pests (especially termites or bark beetles), a great deal of economic loss occurs. Conventionally, various insecticides aimed at controlling the above-mentioned pests and control methods using the insecticides have been proposed, and disclosed in, for example, Patent Documents 1 to 18 and the like.

  However, the insecticides disclosed in the above Patent Documents 1 to 18 and the control methods using the insecticides, such as termites, sense the presence of the insecticide and avoid contact with the insecticide, and the insecticide In order to avoid eating food materials containing soy (so-called “poisonous food materials”), there remains a problem that insecticides do not effectively act on pests.

  In addition, for example, when the termite is controlled using a poison bait containing the insect growth control agent described in Patent Document 12 as a termite killing ingredient, since the insect growth control agent is a slow-acting agent, Termite activity continues for a long time, and during that period, there is a drawback that damage caused by termites such as buildings and materials (including outdoor materials and indoor materials) constructed with industrial materials expands.

  In addition, when using a poison bait containing a high concentration of insect growth control agent in order to reliably control a termite using a poison bait in a shorter period of time, the consumption of the poison bait decreases, that is, the drug component As a result, there is a drawback that termite activity continues for a long period of time.

  Conventionally, in the field of agricultural use or pharmaceutical use, the use of cyclodextrins for the purpose of improving the stability of drugs, improving the solubility of drugs, improving the drug effect, etc. has been proposed. 29 and the like. Similarly, in the field of bactericides, the use of cyclodextrins for the purpose of improving the stability of bactericides, improving the solubility of bactericides, and improving bactericidal effects has been proposed. -34 and the like. Patent Document 35 proposes the use of cyclodextrin for the purpose of improving the stability of pyriproxyfen.

However, even in these patent documents, the development of a method for controlling insect pests, particularly termites and bark beetles, that damage industrial materials remains unsolved.

Such cyclic oligosaccharides may be used alone or in combination of two or more.

  Further, since the site to be modified is a hydroxy group of a monosaccharide constituting a cyclic oligosaccharide, when the monosaccharide is D-glucose, the hydroxy group at the 2-position, 3-position or 6-position thereof, and the monosaccharide is L- In the case of rhamnose, derivatives with various substitution degrees are obtained by substitution reaction at the 2- or 3-position hydroxy group, and these can be used as the cyclic oligosaccharide of the present invention. The desired degree of substitution is not particularly limited because it is determined in consideration of the solubility or dispersibility of the insecticide in the drug of the present invention, but those having a degree of substitution of 20 to 100% are suitable as derivatives. .

〔Insecticide〕
The drug of the present invention is used after being formulated through a step of bringing an insecticide into contact with a cyclic oligosaccharide. By passing through this step, the drug has a repellent effect by the insecticide and has a controlling effect. improves. Inclusion of such a repellent agent in the industrial material increases the frequency of contact between the insecticide contained in the industrial material and the pest, and the amount of damage caused by the pest of the industrial material containing the insecticide is also increased. Increase. These effects are not contrary to the purpose of protecting industrial materials from pests. Increasing the contact frequency increases the amount of insecticide taken into the pests by penetration from the surface of the pests. Increases the amount of insecticide that enters the pest intestine. In addition, if the method disclosed in the present invention is used, it is possible to use the insecticide at a high insecticide concentration such that the conventional method avoids pests and does not provide a sufficient insecticidal effect.

  Any insecticide can be used as long as it is used together with a cyclic oligosaccharide via a solvent so that the repellent action against the insecticide is alleviated. Pest repellent action by insecticides is presumed to be caused by contact stimulation, odor stimulation, taste stimulation, etc. given to pests, but repellent action is a food containing insecticide (so-called “poisonous food”) ) Is a particularly serious problem when exterminating by pests. Therefore, in the past, pest control has been carried out by producing a food material at a low insecticide concentration that does not cause adverse effects due to repellent action, and applying this to a pest for a long period of time. However, if the method of the present invention is used, a poison bait containing a higher concentration of an insecticide can be produced and given to pests, and can be controlled in a shorter period of time and with a smaller poison bait.

<Control method>
Examples of the control method of the present invention include the following two control methods (A) and (B).

(A): The industrial material pest control method, wherein the industrial material contains the agent of the present invention and is installed in the passage of the industrial material pest.
(B): A method for controlling an industrial material pest, wherein the food material contains the agent of the present invention and is installed in a habitat or passage of the industrial material pest.

The above-mentioned control method (A) is a method of installing an industrial material containing the agent of the present invention in the passage of an industrial material pest, and an industrial material containing an insecticide whose repellent property has been relaxed. Since the insecticide adheres to the body surface of the industrial material pests at a high concentration by contact with the pests, effective control of the industrial material pests is achieved. Such a control method (A) may be a method of newly installing an industrial material containing an insecticide whose repellency is relaxed in the passage of the industrial material pest, and the passage of the industrial material pest. The method of adding the chemical | medical agent of this invention with application | coating, spraying, piercing | pouring injection | pouring etc. with respect to the existing industrial material which has become. When the latter method is performed, the industrial material to which the chemical is added is an industrial material that hardly suffers from the harmful effects of pests of industrial materials such as concrete, reinforcing bars and inorganic heat insulating materials in addition to the above-mentioned industrial materials. However, if the material is a passage for industrial material pests, the same control effect can be obtained. The amount of the insecticide used in both methods is determined in consideration of the strength of the insecticidal activity of the insecticide used, the type of insect pest to control, the degree of insecticidal effect required, the type of industrial material containing the insecticide, etc. Therefore, although not particularly limited, for example, when the agent of the present invention is applied to an existing industrial material, the active ingredient of the insecticide is 0.001 to 500 g / in on the surface of the industrial material. to be present at a concentration of m ^2, it is preferable to apply the drug. In the treatment of industrial materials with chemicals, the treatment with insecticides and the treatment with cyclic oligosaccharides are performed separately, and the cyclic oligosaccharides and the insecticide are brought into contact with each other via a solvent inside or on the surface of the industrial materials. A method of treating industrial materials is also preferred.

  On the other hand, the above-mentioned control method (B) is a method of installing a food material containing the agent of the present invention (so-called “poisonous food material”) in the habitat and / or passage of industrial material pests, Pests can be effectively controlled by ingesting a pesticide containing a pesticide with a relaxed sex and absorbing the insecticide from the pest intestinal tract. Such a food material is prepared according to the following manufacturing method. In addition, poisonous bait is also applied by applying, spraying or perforating and injecting the agent of the present invention to wood, woody material, cellulosic material and / or natural material used in buildings such as houses, bridges and wooden playground equipment. Materials can be prepared. Such a control method (B) is particularly effective when the industrial material pest is a termite, using the above-mentioned slow-acting insecticide as an insecticide, bringing a high-concentration insecticide component back into the colony, Other termites can be fed food. The control method (B) makes it possible to increase the amount of insecticide that one termite brings into the colony, so that not only can termites be controlled in a shorter period of time, but also they are controlled with less food. Is also possible. This saves labor for the installation and exchange of food, and also shortens the period for confirming the extermination. Therefore, the control method (B) is extremely useful.

  The amount of the insecticide to be used in the control method (B) is the strength of the insecticidal activity of the insecticide to be used, the type of industrial material pests to be controlled, the degree of insecticidal effect required, the type of industrial material containing the insecticide, etc. Therefore, it should not be particularly limited.

Insecticides to be used in the control method (B) are preferably slow-acting, and specifically include lufenuron, novaluron, noviflumuron, teflubenzuron, diflubenzuron, diflubenzuron, Benzoyl urea compounds such as triflumuron, hexaflumuron, flufenoxuron, bistrifluron, chlorfluazuron, etc .;

Bisacylhydrazine compounds such as halofenozide and methoxyfenozide;
Juvenile hormones such as metoprene, hydroprene, pyriproxyfen, fenoxycarb;
Phenylpyrazoles such as fipronil, vaniliprole, etiprole, acetoprole;
Pyrroles such as chlorfenapyr;
And hydrazones such as hydramethylnon. A termite produced by adding a chemical containing such an insecticide to a material such as a paper towel, paper, wood, woody material, or a paper towel or paper rolled on a roll by coating, spraying, dipping, or the like. It is preferable to prepare so that the active ingredient of an insecticide may become 0.001 to 10% with respect to the weight of this material.

  In addition, in the production of the food material, the treatment with the insecticide and the treatment with the cyclic oligosaccharide are performed separately, and the cyclic oligosaccharide and the insecticide may be brought into contact with each other via a solvent inside or on the surface of the food material. Good.

Which of the above-mentioned control methods (A) and (B) is selected is determined by the state of the pest passage route, the state of the passage route and the existing industrial material around it, the progress of damage, and the like. For example, if an industrial material pest is preferably a termite, when a damaged part or ant tract is observed and a control method can be applied at that location, install a foodstuff or apply a drug at that location A method of adding them by spraying, perforation injection, or the like is useful. In order to control termites in general houses, food materials can be installed under the floor of the house or in the surrounding soil. The amount of food used in this case depends on the progress of termite damage, Although it can be set as appropriate depending on the surrounding conditions, usually about 5 to 200 g of food material is used per place, and the number of food materials installed is ^{2 to} 30 per 50 m ² of house area. Moreover, the termite activity is monitored using a termite bait station (Termite Station) that is normally used, and when the termite activity is recognized, the internal materials and surroundings of the bait station are treated with the agent of the present invention. The method or the method of installing the poisonous bait material of the present invention inside the bait station is also useful as a specific construction method for termite control.

  As the industrial material pests other than termites, bark beetles are preferable, and the above control methods (A) and (B) can be applied. Moreover, also when controlling industrial material food pests other than these, the control methods (A) and (B) can be applied. In addition, for example, in the control of Lyctus brunneus and Dinoderus minutus, an aerosol or liquid containing the agent of the present invention is caused by insect damage on damaged wood or bamboo. A method of injecting from a hole or a method of injecting a hole into a damaged part is also useful. Such a control method is also useful as a control method for American termites (Incisitermes minor). In addition, for example, in the case of controlling squid (Tinea translucens Meyrick), a method of installing the food material of the present invention in a growing place is also useful. In addition, for example, in the case of control of earwigs (Dermaptera), sugar beetle (Armadillidium vulgare), by spraying the agent of the present invention so as to surround the house on the base part of the house, and forming a barrier by an insecticide, A method for preventing and controlling pests entering the house is also useful.
