Description

The present invention relates to a flying insect trap that attracts and captures flying insects such as flies, mosquitoes, and fly flies, and in particular, fly flies such as Drosophila, flea flies, black leaf mushrooms, mushroom flies, and fly flies.

Conventionally, several traps have been proposed for capturing flying insects. For example, Patent Document 1 (Japanese Patent Application Laid-Open No. 2002-272344) discloses a flying insect trap that is a container provided with an insect entrance and contains a water-soluble attractant and a trapping agent that is oil or fat. Although described, there were problems such as liquid spilling and larvae being generated in the container, causing discomfort to the user. The subject of this patent document 1 includes various flying pests such as house flies, and in the examples, an intrusion port having a diameter of 0.8 cm (50 mm ² ) is described. That wasn't true.
Patent Document 2 (Japanese Patent Application Laid-Open No. 2009-112197) includes a main body having an opening through which a flying pest can enter, and a medicine that contains a pest-attracting component and is contained in the main body. Discloses a pest trap or the like that constitutes an escape prevention material formed in a foam shape having a predetermined viscosity. However, these pest traps require the use of a specific escape prevention material, are complicated in construction, and, for example, have not been fully studied on the specifications of the opening.
Further, Reference 3 (Japanese Utility Model Laid-Open No. 6-68463) discloses a flight comprising an adhesive capturing plate having an adhesive layer provided on at least one surface of a base material, and a fixing jig for holding the adhesive capturing plate. A pest capturing tool is described, and the fixing jig is illustrated to have a shape that pierces into the soil of a flowerpot, for example. This flying pest trap was intended for use around foliage plants, but it was not practical because it was sticky to the user's hand during use and was unusable. .

An object of the present invention is to provide a flying pest capturing tool which exhibits a high attracting effect and capture efficiency over a long period of time against flying pests, particularly fly flies, and which is simple in structure and easy to use.

The present invention has been found that the following constitution has an excellent effect for achieving the above-mentioned object.
(1) A flying insect pest trapping device in which a medicine holder in which a liquid medicine composition is held on a carrier is housed in a container, and a lid-like body having a plurality of insect pest entrances is fitted to the opening top surface of the container. The drug composition contains an insecticidal component, a volatile attraction component, and a transpiration-inhibiting substance, and the gap between the drug holder and the lid is 0.2 to 0.6 times the volume of the container A flying pest catcher.

(6) The flying insect trap according to any one of (1) to (5), wherein the carrier is a cellulosic carrier.
(7) The flying insect trap according to any one of (1) to (6), which is used for controlling a fly.

The flying insect trap of the present invention exhibits a high attracting effect and capturing efficiency over a long period of time against flying insects, in particular, fly flies, and since the structure is simple and easy to use, its practicality is extremely high.

The perspective view from the back of one Example of this invention flying insect pest capturing tool is shown. The perspective view from the front is shown.

The flying pest capturing tool of the present invention is configured by fitting a lid-like body having a plurality of pest entrances on the top of the opening of a container containing a medicine holder.
Examples of the material of the container include plastics such as polyester (PET), polyester / polyethylene (PET / PE), polypropylene (PP), metal, and glass. Molded products are preferred. Although the size is arbitrary, for example, a square of 20 to 40 mm and a height of about 10 to 20 mm is easy to use, and a flange portion having a width of several mm is usually provided around the top of the opening. Moreover, although the side surface and bottom part surface of a plastic container may be flat, you may form in arbitrary cross-sectional shapes, such as a parallel protruding pattern, for example.
The flying pest trap of the present invention is preferably such that the top surface of the opening is covered with a barrier film in order to prevent the volatile attraction component from evaporating from the drug carrier in the container before use. The part is used for the sealing. Here, examples of the barrier film include those obtained by laminating PET or PP on an aluminum film layer, but are not limited as long as barrier properties can be imparted and peel properties are excellent.

On the other hand, the lid-like body is an injection-molded product using a plastic such as PP, and a plurality of pest entrances are formed in the portion corresponding to the opening top surface of the container, preferably 20 to 80. Individually drilled. Further, if the support member is extended from one peripheral portion of the lid and / or the container, various installation methods are possible as well as for placement. For example, if it is a hook-shaped support member, it can be used by hooking it to a trash can near the water, and it is particularly useful for controlling Drosophila generated in the kitchen, etc., while the support member converges in a tapered manner. In the case of a stick shape, it can be used by inserting it in the soil of a flower pot, and is therefore particularly suitable for controlling mushroom flies that occur around foliage plants.

The present invention, as will be described later, contains a transpiration inhibitor together with an insecticidal component and a volatile attraction component as a drug composition held in a drug holder, and the gap between the drug holder and the lid is a container. By making the volume 0.2 to 0.6 times the volume, the volatile evaporation attraction component is adjusted to evaporate, and a high attraction effect and capture efficiency are achieved.
In other words, we found that the effective attraction space formed between the top surface of the drug holder and the lid-like body, and the capture space improve the attraction and capture performance against flying pests, and use adhesives The present invention has been completed by taking into account the ease of use.
It is.

In the present invention, the opening area per one pest entrance provided in the lid is preferably set to 1.0 to ²⁰ mm ² , more preferably 2.0 to 10 mm ² .
Conventionally, little attention has been paid to the technical significance of the opening area of the pest entrance. For example, in the embodiment of Patent Document 1 (Japanese Patent Laid-Open No. 2002-272344), the diameter is 0.8 cm (50 mm ² ). An intrusion port is described, and Patent Document 2 (Japanese Patent Laid-Open No. 2009-112197) defines a wide range of 10 to 300 mm ² , while in the examples, the description about the opening area of the opening is omitted. However, as a result of investigating the habits of various flying pests and intensively studying their attracting and capturing properties, the inventors have determined that the opening area of the pest entrance is 1.0 to 20 mm ² , preferably 2.0 to 10 mm. by ² it is was found that may to particularly improve the attractant performance and capturing performance to Kobae acids.

Examples of the insecticidal components constituting the pharmaceutical composition used in the present invention include neonicotinoid-based insecticidal components such as dinotefuran, imidacloprid, clothianidin, natural pyrethrin, allethrin, framethrin, praretrin, resmethrin, phthalthrin, transfluthrin, metfurthrin, phenothrin, Pyrethroid insecticides such as ciphenothrin, permethrin, cifluthrin, etofenprox, organosilicon insecticides such as silafluophene, organophosphorus insecticides such as fenitrothion, diazinon, marathon, prothiophos, and oxadiazole insecticides such as methoxadiazone Pyrazole insecticides such as fipronil, insect growth control agents such as pyriproxyfen and hydroprene, among others, dinotefuran and imidaclopri , Neonicotinoid insecticidal component such as clothianidin are preferred. In particular, dinotefuran is suitable, and about 0.01 to 1.0% by mass is blended in the pharmaceutical composition.
Some of the insecticidal components originally have repellent properties, but they may be used within a range that does not affect the attracting performance of the volatile attracting component.

Volatile inducing ingredients include cutlet of flavor, roasted sugar flavor, sesame oil flavor, shrimp flavor, onion flavor, cabbage flavor, nuka flavor, miso flavor, roast shoyu flavor, maple essence flavor, beer, wine, vinegar, black Examples include vinegar, various fruit extracts, fermented products of vegetables and fruits, and the like, which may be selected as appropriate according to the type of target flying pest.
The range of 1.0-5.0 mass% is suitable for the compounding quantity of this volatile attraction component, and a high attraction effect can be acquired with this mixing ratio.
Of course, sugars such as tri-warm sugar and brown sugar, and feeding attractants such as yeast, honey, egg powder, and pupa powder may be blended.

The pharmaceutical composition used in the present invention contains a transpiration inhibitor in addition to the above components. Examples of the transpiration inhibitor include aliphatic polyhydric alcohols, water-soluble solvents having a boiling point of 200 ° C. or higher, surfactants, and the like, but aliphatic polyhydric alcohols are preferred. Examples of such aliphatic polyhydric alcohols include glycerin, propylene glycol, triethylene glycol, 1,3-butylene glycol, hexylene glycol, and the like. Among these, glycerin is preferable. For example, it is not preferable to use only a highly volatile solvent such as ethanol because the chemical solution holder cannot be kept moist for a long period of time.
Usually, water is further blended to prepare a liquid pharmaceutical composition, but other components can be appropriately added as long as the attractiveness is not hindered. Examples of such components include stabilizers, preservatives, dispersants, bittering agents such as Vitrex, and various auxiliary components such as pigments.
A number of gel-like flying pest traps have also been proposed. However, in the configuration of the present invention, it was confirmed in the test that liquid is more advantageous in terms of trapping ability.

The carrier for holding the liquid drug composition thus obtained is not limited as long as it has a high liquid absorbency and does not cause liquid leakage, and examples thereof include cellulose-based carriers, plastic resin carriers, and inorganic carriers. Cellulosic carriers are preferred from the standpoint of liquid absorbency, and specific materials include, for example, felt. The size of the cellulosic carrier is approximately square so that it fits into the container, and its thickness is set to 0.4 to 0.8 times the height of the container in order to secure the desired attracting space and capture space. It is good to do.

The flying insect trap with such a configuration is compact and excellent in manufacturability, and when used, it is only necessary to place it on the kitchen, a cupboard, in the vicinity of a trash can, on the soil of a flowerpot or the like. Further, if the support member is extended from one peripheral portion of the lid and / or the container, as described above, various useful installation methods can be provided as well as for placement. . For example, if it is a hook-shaped support member, it can be used by hooking it to a trash can etc. In this case, an effective installation space can be secured and there is a risk that foreign substances such as water may enter even if used near water. Few. On the other hand, when the support member has a stick shape that converges in a tapered manner, it is convenient to use it inserted in the soil of a flower pot. According to such an installation method, when water is supplied to a houseplant, water is trapped inside the trap. It has the merit of being difficult to enter.
The shape of the lid-like body is arbitrary, and design can be imparted by imitating the shape of an animal or leaf.

As described above, the packaging form of the flying insect trap of the present invention is preferably a method in which the top of the opening of the container is sealed with a barrier film, and the barrier film is peeled off at the time of use and then the lid-like body is fitted. On the other hand, it is possible to adopt a configuration in which the container and the lid are fitted in advance and the whole is sealed with a barrier film, but in this case, if the fitting is not complete, the drug composition from the container during distribution storage It is necessary to be more careful because things may leak or the drug composition may adhere to the pest entrance and affect the attraction and capture performance.

Examples of insects targeted by the flying insect trap of the present invention include flying insects such as flies, mosquitoes, and fly flies. Is. In addition, the capture device provided with the hook-shaped support member is particularly useful for controlling Drosophila generated in the kitchen or the like. On the other hand, a stick-shaped support member that converges in a tapered shape is used as a houseplant. It is highly useful for controlling mushroom flies that occur around plants. The attracting performance and capturing performance of the product of the present invention usually last for about 1 month, although depending on the type and amount of the pharmaceutical composition.

Next, the present invention will be described in more detail based on examples and test examples, but the present invention is not limited thereto.
