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.

Furthermore, Patent Document 3 (Patent No. 4430121) describes a pest trapping device in which a large number of gel particles containing a pest attractant are contained in a layer in a container having an opening. Clarification of the trapping effect caused by the entry of fruit flies. Pest traps that use gel particles are somewhat inferior in capture performance to liquid pests that make flying pests easily lick drugs, but they have the advantage that they do not spill and the appearance of the pests.
On the other hand, some ideas for improving the attraction performance by improving the shape of the container have been proposed. For example, according to Patent Document 4 (Japanese Patent No. 4463325), if a linear protrusion is provided on the inner surface of the container so as to project toward the drug, the flying pests are attracted to the drug while traveling upward. It is said that However, all the examples of Patent Document 4 use gel particles as a drug carrier, and it is unclear whether such means is appropriate for a drug carrier rich in wettability. As described above, for the type using a drug carrier having high wettability other than gel particles, for example, although it is advantageous in terms of capture performance, it is useful for the ecology and habits of flying pests, particularly the fly flies. The current situation is that the examination based on this has not progressed sufficiently.

The present invention shows a high attracting effect and capture efficiency over a long period of time against flying pests, especially fly flies, when using a chemical solution carrier rich in wettability, and has a simple structure and is easy to use. It is intended to provide ingredients.

The present invention has been found that the following constitution has an excellent effect for achieving the above-mentioned object.
(1) The inside of the tray portion is configured such that a liquid medicine composition in which a liquid medicine composition is held in a wet state on a non-woven carrier is exposed in the tray section, and at least a part of the side end face of the liquid medicine holding body is exposed. In a flying insect trap that is stored with a side and a gap, and a lid having an opening is fitted to the hollow top surface of the tray, the pharmaceutical composition contains an insecticidal component, an attracting component, and a moisturizing component. The moisturizing component is one or more selected from aliphatic polyhydric alcohols, sugar alcohols, and thickening polysaccharides, and the nonwoven carrier has a bulk density of 0.02 to 0.1, And the flying insect trap which the thickness of the side part end surface is 5-30 mm.
(2) The flying insect trap according to (1) , wherein the aliphatic polyhydric alcohol is glycerin.
(3) The flying insect trap according to (1) or (2) , wherein the insecticidal component is dinotefuran.
(4) The flying pest trap according to any one of (1) to (3) , which is for controlling fly flies.

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 of the flying insect trap according to the embodiment of the present invention is shown. The disassembled perspective view of the flying insect trap according to the embodiment of the present invention is shown.

The flying pest capturing tool of the present invention is configured by fitting a lid portion provided with an opening on the hollow top surface of a tray portion in which a chemical solution holder is stored.
Examples of the material of the tray part include plastics such as polyester (PET), polyester / polyethylene (PET / PE), and polypropylene (PP), metals, and glass. Molded products are preferred. The shape and size are arbitrary, but for example, a cup-shaped one having a diameter of 4 to 10 cm and a height of about 2 to 5 cm is easy to use, and it is usually easy to fit the lid around the hollow top surface. In addition, a flange portion having a width of several millimeters is provided for a seal described later. In addition, a fixing piece for storing the chemical liquid holding body is provided at the bottom of the tray section, and the chemical liquid holding body is preferably stored with a gap from the inner side surface of the tray section. By adopting such a configuration, it is possible to provide a situation in which flying pests, in particular, fly flies stay on the side end face of the chemical solution holder exposed in a wet state and are easily licked, thereby contributing to an improvement in capture performance. In addition, although the side surface and bottom part surface of a plastic-made tray part may be flat, you may form in arbitrary cross-sectional shapes, such as an uneven | corrugated pattern, for example.

The flying pest capturing tool of the present invention preferably has a hollow top surface covered with a barrier film in order to prevent the volatile attraction component from evaporating from the chemical solution holder in the tray before use. The flange portion is used for 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 portion usually has an inverted cup shape including an attracting portion and a base portion, and an injection molded product using a plastic such as PP is suitable for the present invention. The attracting part located above may be flat or concave, or the attracting part and the base part may form a dome shape continuously without a boundary. Furthermore, it is possible to imitate the shape of an animal or a leaf to give design.
Further, the attracting part is generally installed in parallel to the hollow lower end surface of the base part, but in the process of proceeding with the present invention, it is better to provide an angle between the attracting part and the hollow lower end surface. It was found that it is more efficient in terms of attracting performance.
The installation method, number, shape, and size of the opening as a pest entrance are not particularly limited, and may be determined as appropriate. Of course, there is no problem even if it is a normal type in which a plurality of circular openings having a diameter of about 2 to 20 mm are installed in the attracting part, but for example, the attracting part is installed inclined with respect to the hollow lower end surface of the base part. The attraction portion is formed as a concave region recessed inward, and the edge portion and the concentric opening portions having a width of about 2 to 8 mm are alternately arranged from the center to the periphery of the concave region. Can be adopted. And it is also possible to install the light reflection part which attracts a flying insect by reflecting external light in the connection part which connects an opening part mutually, and it is also possible to improve attraction performance. Furthermore, if an opening is also provided in the base portion so as to act as a vent for introducing outside air, the volatile attracting component can be efficiently diffused and the attracting performance can be improved.
The edge portion refers to a member having a projecting cross section that protrudes outward, and is newly introduced in the present invention on the basis of ecology and habits that flying insect pests, especially fly flies are likely to stop here. It is a thing.

The present invention devised the configuration of the tray part and the lid part of the flying pest trapping tool and specified a non-woven carrier capable of holding a liquid drug composition in a wet state as described later, and as a drug composition In addition to the insecticidal component and the attracting component, it is characterized by blending a moisturizing component.

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 above insecticidal components originally have repellent properties, but they may be used within a range that does not affect the attracting performance of the attracting components.

Attracting ingredients include brewed vinegars such as balsamic vinegar, wine vinegar, black vinegar, beer, wine, brewed liquor such as Shaoxing liquor, katsuobushi flavor, roasted sugar flavor, sesame oil flavor, shrimp flavor, onion flavor, cabbage flavor, nuka flavor , Flavors such as miso flavor, roasted shoyu flavor, and maple essence, various fruit extracts, fermented products of vegetables and fruits, and the like, and may be appropriately selected according to the type of target flying pest.
The range of 1.0-30 mass% is suitable for the compounding quantity of this volatile attractant component, and a high attraction effect can be acquired with this compounding 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 moisturizing component in addition to the above components. Examples of moisturizing ingredients include aliphatic polyhydric alcohols, sugar alcohols such as sorbitol, thickening polysaccharides such as xanthan gum, water-soluble solvents having a boiling point of 200 ° C. or higher, surfactants, and the like. Alcohols, sugar alcohols, and thickening polysaccharides 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.

In the present invention, the liquid drug composition thus obtained has a bulk density of 0.02 to 0.1 and a side end face of 5 as a carrier capable of holding the liquid pharmaceutical composition in a wet state for a long time without causing liquid leakage. A nonwoven carrier having a thickness of ˜30 mm is employed. Specifically, pulp nonwoven fabrics and felts with a bulk density in the range of 0.02 to 0.1, preferably 0.03 to 0.08, can be mentioned, which has the advantage that stagnant flying pests can easily lick the chemicals. doing. Usually, a configuration in which an inner layer having a smaller bulk density is sandwiched between somewhat dense outer layers is common, but a single layer configuration may of course be used.
Conventionally, it has been known that a chemical holding body rich in wettability is more advantageous than gel particles in terms of capture performance, but there are many problems in commercialization. However, the present inventors have efficiently used a volatile attractant component by combining a pharmaceutical composition containing a specific moisturizing component and a non-woven carrier having a specific bulk density and side end face thickness. Volatilized and achieved high capture performance against flying insects.
That is, when the bulk density of the non-woven carrier is less than 0.02, there is a risk of liquid leakage. On the other hand, when the bulk density exceeds 0.1, the retention performance of the pharmaceutical composition is inferior and the wet state cannot be sufficiently maintained.

In addition, as the drug composition gradually evaporates from the surface and side end face of the drug solution holding body, the drug composition moves from the inside of the drug solution holding body to the surface and side end face to compensate for this. The volatilization contribution from the side end face is also great. Therefore, by setting the thickness of the side end face of the nonwoven fabric carrier to 5 to 30 mm, preferably 10 to 20 mm, it is possible to keep the chemical solution holder moist throughout the predetermined period and to maintain the volatilization performance. It becomes. In the case of a non-woven carrier having a rectangular shape of about 50 mm in length and width and having a side end face thickness of 10 to 20 mm, the amount of impregnation of the drug composition is about 20 to 50 g.

In preparing the drug solution holder, a known conventional method can be appropriately adopted. However, a method of filling the pharmaceutical composition after fixing the nonwoven carrier with a fixing piece provided at the bottom of the tray portion is easy. In addition, if the chemical solution holding body is covered with, for example, a lattice-shaped plastic piece having a large opening, it not only helps to fix the chemical solution holding body, but also the flying pests, particularly the fly flies, can stop here and easily lick the chemical solution. It is more effective because it provides.

In the present invention, it is preferable to store the chemical solution holding body in a state where at least a part of the side end face thereof is exposed, or by providing a gap with the inner side surface of the tray portion. This is based on the habit that flying insect pests, especially fly flies, tend to stay on the side end face of the porous medicinal solution holding body exposed in a wet state after descending along the inner side surface of the tray part. Advantages based on the exposed state or the gap cannot be obtained with a preparation of a type in which gel particles are filled in close contact with the inner surface of the tray portion.
According to Patent Document 4, if a linear protrusion is provided on the inner surface of the tray portion so as to project toward the medicine, the flying pests are attracted to the medicine while traveling on it, and thus are effective. However, in this invention, the effect by another factor is large and the necessity of installing a linear protrusion part was not recognized.
As described above, the packaging form of the flying insect trap of the present invention is preferably a method in which the hollow top surface of the tray portion is sealed with a barrier film, and the barrier film is peeled off during use and then the lid portion is fitted. On the other hand, a configuration in which the tray portion and the lid portion are fitted in advance and the whole is sealed with a barrier film may be adopted. However, in this case, if the fitting is not complete, the medicine from the tray portion is stored during distribution storage. It is necessary to be more careful because the composition may leak or the drug composition may adhere to the opening and affect the attraction performance and capture performance.

When using the flying insect trap of the present invention, it is only necessary to place it on the kitchen, cupboard, in the vicinity of the trash can, on the soil of the flower pot, or the like. Examples of target pests include flying insects such as flies, mosquitoes, and fly flies, and are particularly effective for fly flies such as Drosophila, flea flies, mushroom flies, mushroom flies, and fly flies. 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.
