Description

  The present invention relates to a method for controlling pests for preventing the spread of infections mediated by insects.

  Many blood-sucking pests cause infections by transmitting pathogens to people and animals. In tropical regions in particular, mosquito-borne infections such as malaria and dengue fever kill many people and hinder economic development. In order to control these disease-borne pests, a method of spraying an insecticide or a method of applying a contact insecticide to the surface of an indoor wall (indoor residue spraying method) has been used. However, these methods have poor sustainability, and their duration is several hours for the spraying method and up to 6 months for the indoor residual spraying method. In recent years, insecticide-treated mosquito nets in which a pyrethroid compound is supported on a fiber have been developed (Patent Document 1).

  By sleeping in this mosquito net, humans are cut off from contact with disease-borne pests and unpleasant pests, and can prevent disease infection. The advantage of this method is that the insecticide remains in the fiber for a long period of time, and the control effect is maintained for over 5 years (Non-patent Document 1).

  In addition, there is known a technique for controlling pests such as mosquitoes by sticking a pest control material containing a pest control component on the wall of the room. The pest control material is called Wall Lining (wallpaper) or Insecticide treated plastic sheeting (ITPS). A pyrethroid compound is known as a pest control component (Non-patent Document 2).

  In connection with the invention described in Patent Document 1, a pest control net having a first resin yarn containing a pest control component and a second resin yarn containing an insect growth control agent is known (patent) Reference 2).

(2006) The indoor use of plastic sheeting pre-impregnated with insecticide for control of malaria vectors.Tropical Medicine and International Health 11: 597-603.

  In recent years, vector pests that have acquired resistance to pyrethroid compounds have emerged and have become a major problem. Therefore, it is desired to develop a technology capable of effectively excluding blood-sucking arthropods and preventing the spread of infectious diseases while preventing the development of drug resistance in vector pests.

  For example, malaria is transmitted from person to person by anopheles mosquito vector-borne. In addition, mosquitoes that have just emerged do not have malaria parasites, but possess malaria parasites only after sucking the blood of a person infected with malaria. Therefore, even if a mosquito sucks a person infected with malaria, malaria will not be transmitted unless the mosquito sucks another person's blood.

Here, it is known that an anopheles after sucking blood has a habit of stopping on an indoor wall. Therefore, if a pest control component is supported on a sheet-like carrier and this sheet is placed on the wall surface of the room, an anopheles after blood sucking can be killed, which is an effective measure for preventing the transmission of malaria. .
As described above, malaria is transmitted from person to person, and anopheles just after emergence has no malaria parasite. Therefore, if the above-mentioned seats can be installed in the majority of houses in the village, the transmission of malaria from within the village can be prevented and malaria can be eradicated.

  However, when a sheet-shaped pest control material containing a pest control component is installed on the entire wall surface of the room, infants, pets, livestock, and the like may peel off the pest control material. For this reason, the malaria control effect is not sufficient.

Infants and pets may also lick sheets containing pest control ingredients. Most insecticides carried on the sheet are harmless to humans but may have a harmful image and should not be installed in households with infants or pets such as dogs and cats. Is done.
In other words, as described above, in order to eradicate malaria from the village, the villagers need to be united and cooperated to install the above-mentioned seats in the majority of houses. In a house that keeps pets, etc., it becomes uncooperative with respect to the installation of the seat.

  In addition, considerable costs are required to install the above-described seats in the majority of houses.

  Therefore, the present invention pays attention to the above-mentioned problems and proposes a measure that prevents the spread of infectious diseases because it is difficult to peel off after installation and the bioactive substance can be installed without resistance in any household. An object of the present invention is to provide a technique capable of preventing the development of drug resistance in pests.

  One aspect of the present invention for solving the above-mentioned problems is that imidacloprid and bendiocarb are selected in any region except a region 50 cm from the bottom of a human livelihood space where at least one of humans and livestock enters. Any one of the pesticides (a) and the pesticide (a) has at least one biologically active substance that exhibits different activity against pests and has substantially no repellent activity against pests ( a pest control method characterized in that b) is installed with a wide area.

In the method for controlling pests of the present invention, any one insecticide (a) selected from imidacloprid (imidacloprid) and bendiocarb (b) and the insecticide (a) are different from the insect pests. It uses at least one biologically active substance (b) that exhibits activity and has substantially no repellent activity against pests. Therefore, compared with the method using the conventional sheet | seat etc. which carry | supported only one type of insecticide as a chemical | medical agent, a pest hardly acquires the resistance with respect to an insecticide.
In the present invention, the insecticide (a) is any one selected from imidacloprid and bendiocarb, and these have substantially no repellent activity against pests. Furthermore, the biologically active substance (b) also has substantially no repellent activity against pests. Therefore, the pest control method of the present invention does not inhibit the pest from contacting the insecticide (a) or the bioactive substance (b), and can cause the agent to act on the pest more reliably.

  Moreover, in the pest control method of this invention, a chemical | medical agent is not installed in the area | region of 50 cm from the bottom of the human livelihood space. Therefore, the medicine is not installed in a range where the hand of an infant can reach or a range where a pet's mouth or front foot can reach. On the other hand, since pests often remain at high positions, the effect of controlling pests does not change greatly even if no chemical is installed in the lower part of the human livelihood. Moreover, according to this structure, since the installation amount of an insecticide (a) and a bioactive substance (b) reduces substantially, it also contributes to reduction of cost. More preferably, it is recommended not to install the insecticide (a) or the bioactive substance (b) in an area 1 m from the bottom of the human livelihood.

  Preferably, the insecticide (a) and the bioactive substance (b) are installed inside a wall surface that forms the human livelihood space.

  Preferably, the bioactive substance (b) is an insect growth regulator.

  According to this preferable aspect, the pest which escaped from the insecticidal action of the insecticide (a) can be sterilized. That is, when an insecticide and an insect growth control agent component are used in combination, the insecticide acts on a pest that has not acquired resistance to the insecticide, and can exert an insecticidal effect. On the other hand, an insect growth control agent component acts on a pest that has acquired resistance to an insecticide, so that the pest can be sterilized. Furthermore, for blood-sucking arthropods such as mosquitoes, the blood-sucking inhibitory effect can be enhanced by the synergistic effect of the insecticide and the insect growth regulator component, and further development of resistance to the insecticide can be prevented.

  Preferably, the insect growth regulator is at least one selected from juvenile hormone-like substances and chitin synthesis inhibitors.

  Preferably, the insect growth regulator is pyriproxyfen.

  Preferably, the insecticide (a) and the bioactive substance (b) are installed in a state of being supported on a carrier.

  Preferably, the insecticide (a) and the bioactive substance (b) are respectively carried on different parts of the carrier.

  Preferably, the separate portions are arranged so as to form a stripe or mosaic pattern having a width of 0.1 mm to 50 mm.

  Preferably, the pest control material is in the form of a sheet.

  According to this preferable aspect, installation on a wall of a room or the like is easy.

  Preferably, the carrier has a woven structure or a knitted structure.

  Preferably, the carrier is made of resin or paper.

  According to this preferred aspect, it is possible to easily carry the biologically active substance.

  Preferably, the insecticide (a) and the bioactive substance (b) are kneaded in a carrier, coated on the surface of the carrier, or kneaded in the carrier and coated on the surface of the carrier. Yes.

  Preferably, the insecticide (a) and the bioactive substance (b) are supported on a carrier by printing or laminating.

  Preferably, the insecticide (a) and the bioactive substance (b) are installed in a state where they are carried on wallpaper, curtains or screen doors.

  The pest is a blood-sucking arthropod.

  The blood-sucking arthropod is, for example, a mosquito.

According to the present invention, since the medicine is not peeled off by infants and pets, the effectiveness of preventing infectious diseases is high. Furthermore, since there is no concern about the licking of infants and pets, the residents do not have a sense of resistance to installing drugs, and it is easy to install them in the majority of houses that make up the village.
Further, according to the present invention, it is difficult for a pest to acquire resistance to a biologically active substance. Further, the insecticide (a) and the biologically active substance (b) can be caused to act on the pests more reliably without inhibiting the insects from coming into contact with the drug.
In particular, according to the configuration in which the biologically active substance (b) contains an insect growth control agent, it is possible to infertize the pests that have escaped from the action of the insecticide while killing the pests by the action of the insecticide.

  Hereinafter, embodiments of the present invention will be described. However, the present invention is not limited to the following embodiments.

  The outline of the pest control method according to one embodiment of the present invention to be described below is that the insecticide (a) which is imidacloprid or bendiocarb has different activity against the pests. Two kinds of drugs of the biologically active substance (b) having substantially no repellent activity against pests are carried on a carrier, and this carrier is placed in an area excluding the lower part of the house wall.

  First, the carrier for supporting the insecticide (a) and the bioactive substance (b) will be described. The carrier is not particularly limited as long as it has a planar spread, and may be a sheet, a net, a paper or cloth, or a board.

A structure recommended as a carrier is, for example, the carrier 1 shown in FIG. The carrier 1 is made by plain weaving of ribbon-like films 2 and 3. Specifically, it is composed of a vertical ribbon 2 and a horizontal ribbon 3, which are woven so as to float up and down alternately. Therefore, a mosaic pattern is formed by the vertical ribbon 2 and the horizontal ribbon 3.
The width of the ribbon-like films 2 and 3 is arbitrary, but is preferably 0.1 mm to 50 mm, and more preferably 0.1 mm to 5 mm.
The woven structure is not limited to a plain weave, and may be a twill weave, a satin weave or the like. A configuration using a ribbon as a woven yarn is recommended because it is simple and inexpensive.

  The widths of the ribbons may be the same or different. In the carrier 5 shown in FIG. 2, the widths of the vertical ribbon 6 and the horizontal ribbon 7 are different. In addition, this structure is a sheet | seat structure employ | adopted as a sandbag bag.

Further, the present invention does not exclude the carrier 10 having a structure using the yarn 8 as shown in FIG. Furthermore, it may be a net using a metal wire (not shown).
In addition, like the support | carrier 11 shown in FIG. 4, the thing with the clearance gap 15 between the warp 12 and the weft 13 may be sufficient.

Another recommended structure is a so-called saddle structure. The ridge structure is, for example, a structure like the carrier 17 shown in FIG. 5, in which ribbon-like films 18 are arranged in parallel and in a plane, and these are joined by crossing yarns 20.
Instead of a ribbon, a thread may be used.
Further, in the carrier 17 shown in FIG. 5, the ribbon-like films 18 are arranged closely, but the ribbon-like films 18 may be roughly arranged like the carrier 22 shown in FIG.

  Moreover, the thing of the knitting structure like the support | carrier 26 shown in FIG. 7 may be sufficient. The knitted structure carrier 26 is net-like and inevitably has an opening 27, but the size of the opening is preferably such that mosquitoes cannot pass through.

Moreover, the mat shape like the support | carrier 28 shown in FIG. 8 may be sufficient. Here, the mat is a material having a fabric shape in which yarns having a length of about several centimeters to several tens of centimeters are entangled, and is represented by felt.
The mats may be bonded simply by entanglement of threads, ribbons, or the like, or may be bonded via some adhesive. Further, a combination of heat fusion and the like may be used.

  Further, as a material having a structure similar to a mat, there are natural products such as palm skin (not shown) and insulator fiber (not shown), and these may be used as a carrier.

  Furthermore, paper as shown in FIG. 9, a nonwoven fabric (not shown), or a film-like sheet (not shown) can be used as the carrier 30.

  Further, a plate having rigidity as shown in FIG. 10 can be used as the carrier 31. Specific examples of the plate-like carrier 31 include a plywood represented by a veneer plate, a molded board such as a gypsum board and a resin plate.

  Also, carriers 35, 36, 37, and 38 having a three-dimensional structure as shown in FIGS. 11 to 14 can be employed.

  The material of the carrier is arbitrary, but a material containing a resin as a main component is preferable. In addition, you may use fiber materials, such as a natural fiber and glass fiber, instead of resin. Examples of natural fibers include pulp, cellulose, cotton, and hair.

  As the resin, a thermoplastic resin is preferable. Examples of the thermoplastic resin that can be used include polyolefin resin, polyvinyl alcohol, polyvinyl acetate, polycarbonate, polyester, polyamide, polystyrene, polymethyl methacrylate, acrylonitrile-butadiene-styrene copolymer, and polyvinyl chloride.

Here, the thermoplastic resin is preferably a polyolefin resin. As the polyolefin resin, the following compounds are preferable.
Α-olefin homopolymer: for example, polyethylene, polypropylene and the like.
-Ethylene-α-olefin copolymer: For example, ethylene-propylene copolymer, ethylene-butene-1 copolymer, ethylene-4-methyl-1-pentene copolymer, ethylene-hexene copolymer and the like.
-Copolymer of an organic carboxylic acid derivative having an ethylenically unsaturated bond and ethylene: for example, ethylene-methyl methacrylate copolymer, ethylene-vinyl acetate copolymer, ethylene-acrylic acid copolymer, ethylene-vinyl acetate -Methyl methacrylate copolymer and the like.

  Next, the insecticide (a) and the bioactive substance (b) that are drugs carried on the carrier 1 will be described.

  The insecticide (a) in the present invention is bendiocarb, which is a kind of carbamate insecticide, or imidacloprid, which is a kind of neonicotinoid insecticide.

  The biologically active substance (b) in the present invention exhibits a different action against insect pests than the insecticide (a) and has substantially no repellent activity against insect pests. The biologically active substance “having a different action against insect pests than the insecticide (a)” is a biologically active substance other than carbamate insecticides for bendiocarb, and neonicoti for imidacloprid. It is a biologically active substance other than a noid insecticide.

  Examples of biologically active substances that can be used as the biologically active substance (b) include insecticides other than the insecticide (a), insect growth regulators (including fertility agents), and the like.

  Furthermore, you may carry | support arbitrary compounding agents on a support | carrier as needed. Examples of the compounding agents include antioxidants, pigments, fragrances, deodorants, spreading agents, ultraviolet absorbers, light stabilizers, lubricants, antiblocking agents, antistatic agents, surfactants, fillers, Examples include difficult agents, plasticizers, and rust inhibitors.

In the pest control method of this embodiment, the insecticide (a) and the biologically active substance (b) are supported on any of the aforementioned carriers.
Here, the loading of the drug may be carried by mixing the insecticide (a) and the insect growth control agent, but it is recommended that the drug be loaded separately in each region.
For example, if the carrier 1 or the like has a distinction between warp (or ribbon) and weft (or ribbon) as shown in FIGS. 1, 2, 3, and 4, the insecticide (a) is supported on either the warp or weft. The insect growth control agent is supported on the other side.
For example, as shown in FIGS. 1, 2, 3, and 4, the carrier 1 has a distinction between warp (or ribbon) and weft (or ribbon), and the ribbon-like films 2 and 3 have a width of 0.1 mm to 50 mm. If this is the case, the drug-carrying portion forms a stripe or mosaic pattern having a width of 0.1 mm to 50 mm. Similarly, if the widths of the ribbon-like films 2 and 3 are 0.1 mm to 5 mm, the drug carrying portion forms a stripe or mosaic pattern having a width of 0.1 mm to 5 mm. Become.

  Further, in the case of the carrier 26 having a knitted structure as shown in FIG. 7, the insecticide (a) is carried on one of the blackened yarn 24 and the white yarn 25, and the insect growth control agent is carried on the other. .

  It is also recommended that an insect growth control agent be mixed with several yarns or ribbons carrying the insecticide (a).

  Alternatively, the carrier may be divided into regions, and the insecticide (a) and the insect growth control agent may be supported for each region. In the example shown in FIG. 15, the insecticide-carrying site 40 and the insect growth control agent component-carrying site 41 are arranged so as to form a mosaic pattern. Specifically, the insecticide carrying part 40 and the insect growth control agent component carrying part 41 are both rectangular, and these parts constitute “small pieces”, and the small pieces gather to form a mosaic pattern. Yes. The arrangement of each small piece (each part) is regular such that the insecticide carrying part 40 and the insect growth controlling agent component carrying part 41 are alternated. Although it does not specifically limit as a size of a small piece, The length of the short side becomes like this. Preferably it is 0.1 mm to 50 mm, More preferably, it is 0.1 mm to 5 mm. In addition, the arrangement of the small pieces may be a regular pattern repetition or irregular. Further, the shape of the small piece is not limited to a rectangular shape, and may be another shape.

FIG. 16 shows another example of a mosaic shape. In the example of FIG. 16, the insecticide (a) is carried over the entire surface of the carrier, and the insect growth control agent component carrying sites 46 are dispersed in the inside, as if the insecticide carrying site 45 is the sea, insect growth control. It arrange | positions so that the agent component carrying | support part 46 may become an island. The arrangement of the islands may be a regular pattern repetition or irregular. There is no particular limitation on the size and shape of the island, and there is no particular limitation on the area occupied by the island relative to the sea.
In this example, the sea and the island may be reversed, and the insect growth control agent component carrying site may be the sea and the insecticide carrying site may be the island.

  In the example shown in FIG. 17, the insecticide carrying part 50 and the insect growth control agent component carrying part 51 are arranged so as to form a stripe pattern. More specifically, the insecticide-carrying site 50 and the insect growth control agent component-carrying site 51 are both strip-shaped, and the sites are alternately arranged to form a stripe pattern. The stripe width is preferably 0.1 mm to 50 mm, more preferably 0.1 mm to 5 mm.

  The patterns as shown in FIGS. 15 to 17 can be formed, for example, by weaving or knitting using a yarn carrying an insecticide (a) and a yarn carrying an insect growth control agent. It can also be formed by printing or laminating.

  In the embodiment shown in FIG. 15 to FIG. 17, the site for supporting each drug (site for forming a pattern) may be the entire surface of the carrier or a part thereof. That is, there may be a portion where no drug is carried.

  In addition to the insecticide (a) and the biologically active substance (b), when another drug such as a synergist is further carried, the area can be carried separately for each drug. In addition, a set of drugs other than the insecticide (a) (for example, an insect growth control agent and a synergist) is set, and the pesticide (a) and the set of drugs are carried separately in separate areas. be able to.

  The method of supporting the drug (insecticide (a) and insect growth control agent) on the carrier is arbitrary, and examples thereof include a method of kneading the drug on the carrier and a method of coating the drug on the surface of the carrier. One of these methods may be used, or both may be used in combination. That is, for each drug, there are three types: (A) kneaded in the carrier, (B) coated on the carrier surface, (C) kneaded in the carrier and coated on the carrier surface. These methods can be selected.

  It is also possible to carry the drug on the carrier by printing or laminating. The carrier may be brushed or sprayed with the drug.

  The pest control method of the present embodiment is a method in which the carrier carrying the insecticide (a) and the insect growth control agent (bioactive substance (b)) is installed in an area excluding the lower part of the house wall. . Hereinafter, the relationship between the house and the carrier will be described.

  The house 60 is a building where people live, and is composed of an outer wall 61 and a roof 62 as shown in FIG. The outer wall 61 surrounds four sides, and a door 63 is provided in part.

In the house 60, a region surrounded by the outer wall 61 is a living space 65. Actually, there is a partition in the living space 65, and the partition is divided into a plurality of rooms. However, in order to facilitate the description, the living space 65 will be described as having no partition.
Accordingly, the area surrounded by the inner surface of the outer wall 61 (hereinafter referred to as the inner wall) is the living space 65 of the house 60. In this embodiment, the area is surrounded by four inner walls 66, 67, 68, 70 as shown in FIG. It is.
In this embodiment, carriers and the like are provided on all four inner walls 66, 67, 68, 70. The carrier may be any of those described above, but is a plain weave carrier 1 as shown in FIG. In the present embodiment, the carrier 1 is attached to the inner walls 66, 67, 68, 70 by a plurality of pins 71 as shown in FIG.

  The region where the carrier 1 is affixed is substantially the entire inner wall, but the lower ends of the inner walls 66, 67, 68, 70 are excluded. That is, the carrier 1 does not exist in the region of the height H from the floor surface 72 or the soil surface. As described above, in this embodiment, the carrier excluding portion 75 is provided below the inner walls 66, 67, 68 and 70. The height H of the carrier exclusion portion 75 is 50 cm or more, and preferably 1 m or more.
