Description

  The present invention relates to a flying pest trap that attracts and captures flying pests.

  For the purpose of controlling flying pests such as fly flies, various flying pest traps with an attractant inside are commercially available. In order to attract flying insects efficiently to the flying insect trap, it is necessary to use an attractant with a high attracting effect and to devise the structure of the flying insect trap. For example, since flying pests tend to react to a specific color under specific conditions, it is thought that the attracting effect can be enhanced if the color that appears on the appearance of the flying pest catcher is a color that the flying pest likes. .

  Conventionally, in a flying insect trap used to capture a fly, etc., there is one that attempts to enhance the attracting ability of the flying insect by coloring the vicinity of the opening where the flying insect invades in a color close to black. (For example, see Patent Document 1). According to Patent Document 1, a flying pest is attracted to a color close to black in the color space in the CIE 1976 lightness L * of the L * a * b * color system, and the CIE 1976 lightness L * is 70 or less It is shown that the tendency is remarkable. For this reason, it is said that the flying pest can be efficiently captured by coloring the vicinity of the opening of the flying pest trapper in a color close to black (CIE 1976 brightness L * is 70 or less).

  In addition, there has been an attempt to improve the attractiveness of flying insects by visualizing the flying insect traps with two different colors (see, for example, Patent Document 2). According to Patent Document 2, it is said that the attractiveness can be improved by coloring the flying pest catcher into two colors of black and green or blue where the flying pest exhibits attractiveness.

JP 2005-245279 A JP 2011-142876 A

  The flying pest trap of Patent Document 1 is examining the color around the opening into which the flying pest invades, but it is not a color scheme for the entire appearance of the flying pest trap. For this reason, the effect of attracting flying insects by color is limited, and there is much room for improvement. In addition, the attractiveness of flying insects to colors varies depending on the environment in which the flying insects exist and the type of flying insects, so it is difficult to determine that the attractiveness of black is generally high.

  Since the appearance of the flying insect trap of Patent Document 2 is a combination of black and green or blue, its overall hue and saturation are low. Considering this, when the installation environment of the flying pest trap is in the dark or at night, there is a possibility that a sufficient attraction effect cannot be exhibited.

  The present invention has been made in view of the above-mentioned problems, and in particular, by focusing on the combination of colors appearing on the appearance of the flying insect trap, fruit flies such as Drosophila, flea flies, mushroom flies, mushroom flies, and fly flies An object of the present invention is to provide a flying insect trap capable of exhibiting an excellent attracting effect against flying insects represented by.

The characteristic configuration of the flying pest trap according to the present invention for solving the above problems is as follows.
A flying pest trap that attracts and captures flying pests,
A lid portion formed with an attraction opening for attracting the flying pests inside;
A tray portion for storing flying pests that have entered the interior from the attraction opening;
With
The lid part and the tray part are L * a * b * color system (CIE 1976), and both have a color tone of L *: 20 or more, a *: 0 or more, b *: 0 or more, and both At least one of a * and b * has a different color tone.

The present inventors diligently investigated the attractiveness of flying insects to colors, and in an environment where flying insects such as kitchens appear favorably, flying insects have a relatively large hue and saturation (orange, brown) Etc.) and was found to be attracted effectively in such a color direction.
Therefore, the flying insect trap of this configuration has the lid portion and the tray portion in the L * a * b * color system (CIE 1976), both L *: 20 or more, a *: 0 or more, b *: 0 or more. And at least one of both a * and b * has a different color tone. As a result, the lid part and the tray part of the flying pest trap have a lightness of a certain level or higher and a relatively high hue and saturation, so that the flying pests can be attracted effectively. Further, since the colors of the lid and the tray are different from each other, the flying insects can easily distinguish the lid from the tray. Accordingly, it is possible to design a flying insect trap that has an attractive effect that facilitates attracting flying insects, particularly toward the lid.

In the flying insect trap according to the present invention,
The lid part and the tray part are L * a * b * color system (CIE 1976), and the color tone is set so that the difference between both a * and / or the difference between both b * is 10 or more. Preferably it is.

  According to the flying insect trap of this configuration, the difference in color tone between the lid portion and the tray portion becomes clearer, so that the flying insects can more easily distinguish between the lid portion and the tray portion. As a result, the flying pest is easily attracted by the lid, and the attracting effect of the flying pest trap can be further enhanced.

In the flying insect trap according to the present invention,
The lid has an L * a * b * color system (CIE 1976) and has a color tone of L *: 30 or more, a *: 15 or more, b *: 15 or more,
The tray portion preferably has a color tone of L *: 40 or more, a *: 5 or more, and b *: 5 or more in an L * a * b * color system (CIE 1976).

  According to the flying insect trap of this configuration, the lid portion has an orange color tone and the tray portion has a brown color tone. Flying pests exhibit particularly good reaction (attractiveness) to such color combinations, so that they can be attracted and captured more efficiently.

In the flying insect trap according to the present invention,
The lid part preferably includes an inclined part capable of reflecting light.

  According to the flying pest trap of this configuration, the lid part in which the inclined part of the lid part reflects the light so that the flying part can be surely visually recognized by the flying pest, the lid part on which the flying pest is formed It becomes possible to attract more effectively.

In the flying insect trap according to the present invention,
The tray part is preferably configured to be transparent or translucent.

  According to the flying pest trap of this configuration, the inside of the tray part where the flying pests accumulate can be surely seen from the outside. It can be a trap.

  Hereinafter, embodiments relating to the flying insect trap of the present invention will be described. However, the present invention is not intended to be limited to the configurations described in the embodiments and drawings described below.

<Structure of flying insect trap>
FIG. 1 is a perspective view of a flying insect trap 100 according to an embodiment of the present invention. The flying pest trap 100 is used to capture and control various flying pests (particularly fruit flies), and includes a tray unit 10 and a lid unit 20. Hereinafter, the tray unit 10 and the lid unit 20 will be described in detail.

[Tray part]
FIG. 2 is a perspective view of the tray unit 10 constituting the lower part of the flying pest trap 100. The tray unit 10 is a cup-shaped container that stores dead insects. As shown in FIG. 2, the tray unit 10 is configured such that a later-described drug unit 30 is installed at or near the inner bottom thereof, and the flying pests are killed by the insecticidal components contained in the drug held in the drug unit 30. Has been. The tray part 10 is provided with an arrangement member 11 for positioning the drug part 30 at substantially the center. In the present embodiment, by restricting the side surface of the drug part 30 with the four arrangement members 11, the drug part 30 is arranged at substantially the center of the tray part 10. After setting the drug part 30 between the four arrangement members 11, a fixing part (not shown) is mounted on the arrangement member 11, and the drug part 30 is fixed. In addition, for fixing the drug part 30, it is possible to employ a rod-like member that penetrates the center of the drug part 30, a clamp that holds the drug part 30, or the like instead of the arrangement member 11 and the fixing parts.

  The tray portion 10 is provided with a flange portion 12 for attaching and detaching a lid portion 20 described later. In the new state, for example, a barrier film (not shown) formed by laminating an aluminum film and a resin film is adhered to the flange portion 12 to seal the inside, and the medicine contained in the medicine portion 30 is dried. Is preventing. At the time of use, the barrier film is peeled off from the flange portion 12 and fitted with the lid portion 20 with the inside exposed.

  On the inner side surface of the tray part 10, a band-like protrusion 13 for guiding the flying pests to the drug part 30 is provided. In the present embodiment, four strip-shaped protrusions 13 are provided at equal intervals on the inner side surface of the tray unit 10. The size of one band-shaped protrusion 13 is set to a width of 3 to 10 mm, a thickness of 0.5 to 3 mm, and a length of about 10 to 30 mm. Each of the band-shaped protrusions 13 is provided over a range from the flange 12 to the vicinity of the root of the arrangement member 11. The drug part 30 is installed so as to be in contact with at least a part of each belt-like projection part 13. The flying pest that has entered the inside of the flying pest trap 100 moves toward the drug part 30 below while traveling along the belt-like protrusion 13. And if it reaches | attains to the position where the strip | belt-shaped projection part 13 and the chemical | medical agent part 30 contact, or its vicinity, a flying insect will die by the effect | action of the insecticidal component contained in a chemical | medical agent. Thus, by providing the belt-like protrusion 13 on the inner side surface of the tray unit 10, the captured flying pest is reliably guided to a deep position of the tray unit 10 where the drug unit 30 is installed, and the drug unit 30. The flying pests that have reached and died can be stored in the tray section 10.

  As described above, the drug unit 30 installed in the tray unit 10 volatilizes the attracting component contained in the soaked drug to the outside, attracts the flying pests to the inside of the flying pest trap 100, and attracted flying. The insecticide is killed by contacting or ingesting the insecticide contained in the drug against the pest. The drug part 30 is obtained by soaking a drug in an absorbent carrier. For the carrier, for example, a pulp nonwoven fabric or felt can be used. In order to make the carrier thick, a plurality of thin pulp nonwoven fabrics or felts may be laminated. In order to efficiently absorb the drug while maintaining the shape of the pulp nonwoven fabric or felt, a web can be formed on the surface or embossed by the spunlace method. Instead of pulp nonwoven fabric or felt, the carrier of the drug part 30 may be composed of sponge, paper, fiber aggregate, etc. that can absorb liquid. Alternatively, a liquid attracting component and an insecticidal component mixed into a gel may be used as the drug part 30. The medicine includes an attractant for causing the flying pests to enter the inside of the tray unit 10 and an insecticide for killing the flying pests. Examples of attractants include balsamic vinegar, apple vinegar, rice vinegar, brown rice vinegar, rice vinegar, soybean vinegar, black vinegar, wine vinegar, sudachi vinegar, red vinegar, straw vinegar, malt vinegar, purple potato vinegar, sugarcane vinegar, etc. These may be used alone or in combination. Among these attractants, balsamic vinegar is particularly preferable because of its excellent attracting effect against flying pests. Insecticides include, for example, allethrin, praretrin, imiprothrin, phthalthrin, transfluthrin, resmethrin, phenothrin, ciphenothrin, permethrin, cypermethrin, etofenprox, cyfluthrin, deltamethrin, bifenthrin, fenvalerate, fenpropathrin, empfenthrin, silafluoline , Methofluthrin, profluthrin, natural pyrethrin, pyrethroid compounds such as Pyrethrum extract, carbaryl, propoxur, mesomil, carbamate compounds such as thiodicarb, organic phosphorus compounds such as fenitrothion, diazinon, marathon, pyridafenthion, prothiophos, phoxime, chlorpyrifos, dichlorvos , Oxadiazole compounds such as methoxadiazone, fipro Phenylpyrazole compounds such as sulfone, sulfonamide compounds such as amidoflumet, neonicotinoid compounds such as dinotefuran and imidacloprid, insect growth control compounds such as metoprene, hydroprene, pyriproxyfen, etc. Can be used as a mixture. Among these insecticides, dinotefuran, which is a neonicotinoid compound, is particularly preferable because it has low repellency against flying insects and does not inhibit the attracting action of the attracting agent. In addition to the above attractants and insecticides, for example, alcoholic beverages, sake lees, sugars, fruits, fruit processed products, lactic acid products, seafood, processed seafood products, seafood extracts, meat, processed meat products Other attractants such as meat extract and fragrance may be included. Furthermore, if a moisturizing component such as an aliphatic polyhydric alcohol such as glycerin, a sugar alcohol such as sorbitol, or a thickening polysaccharide such as xanthan gum is included, the efficacy of the drug can be exhibited over a long period of time.

Since the tray unit 10 and the lid unit 20 are configured to be detachable, the lid unit 20 is removed as necessary to replace the drug unit 30 inside the tray unit 10 or to attract the inside of the tray unit 10. It is possible to take out the dead bodies of flying pests that have been killed. The horizontal section of the tray unit 10 is configured to be rectangular, circular, or the like so that it can be easily installed in a living space such as a kitchen or living room, but may be indefinite. The bottom area of the tray unit 10 is set to about 10 to 100 cm ² so that the flying pest trap 100 can be installed without conspicuous. Moreover, if the depth of the tray part 10 shall be about 1-10 cm, stability will become favorable, installing the chemical | medical agent part 30 reliably. The tray unit 10 is formed into a cup shape by injection molding, vacuum molding, bulging molding, blow molding, or the like using a thermoplastic resin.

  On the outer surface of the tray portion 10, a recess 14 is formed in which the belt-like protrusion 13 is engaged. The recess 14 is provided in order to improve the loading efficiency of the tray unit 10. When a large number of cup-shaped tray portions 10 are manufactured and stacked in the height direction, the upper ends of the strip-shaped protrusions 13 provided on the outer surface of the tray portion 10 are placed on the outer surface of the tray portion 10 stacked thereon. Engages with the formed recess 14. For this reason, it becomes possible to stack a plurality of tray sections 10 in a compact manner, and the loading efficiency during storage and transportation of products is improved.

  The tray unit 10 is preferably configured to be transparent or translucent. In this case, since the inside of the tray part 10 in which the flying pests accumulate can be surely seen from the outside, for example, the flying pest trap 100 can be easily handled by confirming the attracting effect and grasping the replacement time. be able to. In order to configure the tray unit 10 to be transparent or translucent, for example, a colorless material such as polypropylene resin, PET resin, acrylic resin, polyethylene resin, polystyrene resin or the like is used as the material of the tray unit 10. Or The thickness of the tray part 10 may be formed thin so that the inside can be seen through.

[Cover]
FIG. 3 is a side view of the flying insect trap 100 in which the lid portion 20 is attached to the tray portion 10. FIG. 4 is a side sectional view of the flying pest trap 100. FIG. 5 is a plan view of the flying pest trap 100 as seen from the lid 20 side. The lid 20 attracts flying pests by introducing outside air into the flying pest trap 100 and diffusing the attracting component from the drug unit 30 to the outside. Moreover, the cover part 20 prevents the medicine part 30 accommodated in the tray part 10 from being exposed. As shown in FIG. 3, the lid portion 20 includes an attracting structure portion 21 that attracts flying pests and a connection portion 22 that engages with the flange portion 12 of the tray portion 10. The lid portion 20 is formed by injection molding using a thermoplastic resin, vacuum molding, bulging molding, blow molding, or the like, and as shown in FIG. 4, the hollow structure in which the attracting structure portion 21 and the connection portion 22 are integrated. Configured as a structure.

  As shown in FIG. 5, the attracting structure 21 includes a plurality of attracting openings 23 that attract the flying pests into the flying pest trap 100. In the present invention, in order to efficiently evaporate the attracting component contained in the drug part 30 to the outside through the attracting port 23, the attracting structure part 21 is composed of four step parts 21a to 21d having different heights as shown in FIG. It comprises and attracting openings 23a-23e are formed in each step part 21a-21d. FIG. 4 is a side sectional view passing through the center of the flying pest trap 100 (point P in FIG. 5), so that the induction port does not appear in the step portion 21c, but in reality, the induction port is formed in the step portion 21c. 23c and 23d are formed. In the present embodiment, the step portions 21a to 21c are provided adjacent to each other in order, and the step portion 21d is provided on the opposite side of the step portion 21a. The step portion 21a is formed with an induction port 23a, the step portion 21b is formed with an induction port 23b, the step portion 21c is formed with induction ports 23c and 23d, and the step portion 21d is formed with an induction port 23e. As described above, when the plurality of attracting openings 23 are arranged in a step shape, the air permeability of the flying insect trap 100 is increased and the air flow path is complicated, so that the diffusion of the attracting component volatilized from the drug part 30 is promoted, As a result, the effect of attracting flying pests can be improved.

  At least half of the attracting openings 23a to 23e formed in the step portions 21a to 21d have shapes different from each other. “Different shapes” means shapes that do not completely match when superimposed. Therefore, for example, a similar shape or a shape having a line symmetry (mirror image) relationship does not completely coincide with each other even if they are overlapped with each other. In addition, although it is most preferable if all of the plurality of attracting openings 23 formed in the attracting structure portion 21 have different shapes, it is not essential, and more than half of the attracting openings 23 have different shapes. It only has to be. If more than half of the attracting openings 23 have different shapes, the attracting ingredients included in the drug part 30 inside the flying insect trap 100 are volatilized to the outside via the attracting openings 23. The attracting component is released while diffusing in a complicated manner due to the difference in the shape of 23. Therefore, the attracting component can easily reach the flying pests flying in various patterns in various environments, and as a result, the flying pests can be attracted to the flying pest trap 100 effectively and continuously.

  The attracting openings 23a to 23e are formed at random positions or point-symmetric positions with respect to the center of the lid portion 20 when viewed from above. The “center of the lid portion 20” corresponds to the position of the center of gravity of the shape in a top view. For example, as shown in FIG. 5, when the lid 20 is configured to be circular in a top view, the center of the circle corresponds to the center P of the lid 20. “Random position with respect to the center P of the lid part 20” means, in particular, when the attracting openings 23a to 23e are viewed from the center P of the lid part 20 and the distances to the respective attracting openings 23a to 23e and the respective attracting openings 23a. It means a positional relationship in which at least one of the shapes of ˜23e is different from each other. That is, the plurality of attracting openings 23 are formed in the lid portion 20 so as to be substantially irregularly arranged in a top view. In this way, when a plurality of attracting openings 23 are formed in the lid portion 20 in a random arrangement, diffusion of the attracting components from the attracting openings 23 becomes more complicated, so that the attracting components can be diffused over a wide range, and flying insect pests. The effect of attracting flying insects to the trap 100 can be further improved. Although not shown, when the attracting openings 23a to 23e are formed at positions that are point-symmetric with respect to the center P of the lid portion 20 when viewed from the top, the diffusion amount of the attracting components from the attracting openings 23a to 23e is Since it can be made different according to a certain rule, the diffusion state of the attracting component can be easily controlled. For example, the attracting component can be diffused upward so as to form a vortex with a perpendicular passing through the center P of the lid 20 as an axis to enhance the effect of attracting the flying pest to the flying pest trap 100 in a specific direction. It becomes.

  The attracting structure portion 21 includes an inclined portion 24 that can reflect light. In the present embodiment, the inclined portion 24 is provided so as to surround the step portions 21a to 21c. The inclined portion 24 reflects light, so that the lid 20 can be surely visually recognized by the flying pest, and the flying pest can be effectively attracted toward the lid 20 where the attracting port 23 is formed. As described above, by providing the inclined portion 24, it is possible to assist the attractive effect by the attractive component by the inclined portion 24 while effectively using the surface of the lid portion 20. The inclination angle of the inclined portion 24 is preferably set to 15 degrees or more with respect to the connecting portion 22 in a side view.

  The connection unit 22 connects the attracting structure unit 21 to the tray unit 10. For this reason, the connection part 22 is comprised in the shape which can receive the flange part 12 of the tray part 10. FIG. Although it is preferable that the connection part 22 can be easily attached to and detached from the flange part 12 by engagement of protrusions or the like, for example, the connection part 22 may be screwed into the flange part 12. When the connecting portion 22 on the lid portion 20 side and the flange portion 12 on the tray portion 10 side are engaged, the flying pest trap 100 is in use.

<Color scheme of flying insect traps>
Flying pests are known to exhibit different reactivity (attraction) for various colors. Therefore, the present inventors have conducted an intensive study on the attractiveness of flying pests with respect to color, and in an environment where flying pests such as kitchens appear and appear, flying pests have a relatively large hue and saturation (orange color). , Brown color, etc.). It has been found that flying pests are effectively attracted in such a color direction. Based on this new knowledge, as a result of trying to color the flying pest trap 100 described above in a color excellent in the flying pest attracting effect, the attracting effect by the color appearing on the appearance of the tray part 10 and the lid part 20; A synergistic effect with the attracting effect by the attracting component that volatilizes from the drug part 30 inside the flying insect trap 100 is recognized, and it has been found that a remarkable attracting effect of flying insects can be obtained compared to the conventional one. Hereinafter, the color arrangement of the tray unit 10 and the lid unit 20 in the flying pest trap 100 will be described.

  In performing the color arrangement of the flying insect trap 100, the color tone (object color) of the tray unit 10 and the lid unit 20 was determined based on the L * a * b * color system. The L * a * b * color system is a three-dimensional approximate uniform color space recommended by the International Commission on Illumination (CIE) in 1976 to express lightness, hue, and saturation. The L * a * b * color system (CIE 1976) is defined as JIS Z 8729 in the Japanese Industrial Standard. In the L * a * b * color system (CIE 1976), L * is an index representing lightness, L *: 0 is black, and L *: 100 is white. a * and b * are indices representing hue and saturation. At a *, the plus approaches red and the minus approaches green. At b *, plus approaches yellow and minus approaches blue. In the L * a * b * color system (CIE 1976), for example, a C light source that is a standard light source is used and measured at a viewing angle of 10 degrees. The lightness, hue, and saturation in the L * a * b * color system (CIE 1976) are measured using, for example, a color difference meter (for example, a color and color meter “CR-400” manufactured by Konica Minolta Co., Ltd.), spectral The measurement is performed using a color densitometer (for example, a spectral color densitometer “X-Rite 939” manufactured by Nippon Flat Equipment Co., Ltd.).

  In this embodiment, the tray part 10 and the lid part 20 constituting the flying pest trap 100 are both L *: 20 or more, a *: 0 or more, b in the L * a * b * color system (CIE 1976). *: It was set so that it had a color tone of 0 or more and at least one of both a * and b * had a different color tone. L *: 20 or more means that the tray unit 10 and the lid unit 20 have a certain level of brightness. a *: 0 or more, b *: 0 or more means that the tray 10 and the lid 20 are red to brown to yellow. Further, when at least one of a * and b * is different from each other, the color tone of the tray portion 10 and the lid portion 20 is different from each other. Here, it is preferable that the a * and b * of the tray part 10 and the lid part 20 are set so that the difference between both a * and / or the difference between both b * is 10 or more. That is, only the difference of a * between the tray part 10 and the lid part 20 is 10 or more, only the difference of b * is 10 or more, and both the difference of a * and the difference of b * are 10 or more. Set to be. When set to such a color tone, the tray unit 10 and the lid unit 20 have a lightness of a certain level or more and a relatively high hue and saturation. You can be attracted to 100. Further, when the difference in color tone between the tray portion 10 and the lid portion 20 becomes clear, it becomes easy for the flying insects to distinguish between the tray portion 10 and the lid portion 20, so that the color tone of the tray portion 10 and the lid portion 20 is appropriately set. For example, a flying pest trap 100 that is easy to handle and that can visually inspect the inside of the tray 10 where the flying pests accumulate while attracting the flying pests effectively toward the lid 20 is designed. can do.

  In the color arrangement of the flying pest trap 100, preferably, the color of the lid 20 is L *: 30 * or more, a *: 15 or more, b *: L * a * b * color system (CIE1976). The color tone of the tray unit 10 is set to L *: 40 or more, a *: 5 or more, b *: 5 or more in the L * a * b * color system (CIE 1976). More preferably, the color tone of the lid 20 is set to L *: 30 or higher, a *: 30 or higher, b *: 20 or higher in the L * a * b * color system (CIE 1976). The color tone is set to L *: 40 or more, a *: 10 or more, b *: 10 or more in the L * a * b * color system (CIE 1976). When the color tone is set in this way, generally, the lid portion 20 has an orange color tone and the tray portion 10 has a brown color tone. Since the flying pest exhibits a particularly favorable reaction (attracting property) with respect to this color combination, it is possible to attract and capture the flying pest more efficiently inside the flying pest trap 100.

  As a coloring method of the flying insect trap 100, when the tray portion 10 and the lid portion 20 are molded, a pigment or a colorant is mixed with a resin as a raw material. Or the method of coloring the surface of the tray part 10 and the cover part 20 after shaping | molding with a coating material, and the method of sticking the colored film or seal | sticker to the tray part 10 and the cover part 20 after shaping | molding may be sufficient.

  The flying pest trap 100 having the color tone set as described above has a higher effect of attracting flying pests by combining the color of the tray portion 10 and the color of the lid portion 20, and also has an attracting component that evaporates from the drug portion 30. Combined with the flying pest attracting effect, a remarkable attracting effect (synergistic effect) can be exhibited.

<Another embodiment>
(1) Although it has been described in the above embodiment that the tray portion 10 can be configured to be transparent or translucent, the lid portion 20 can also be configured to be transparent or translucent. In this case, the flying insect trap 100 can easily visually recognize the inside of the tray part 10 without removing the lid part 20 while maintaining a high attraction effect.

(2) In the above embodiment, it has been described that the lid 20 preferably has an orange color tone, but the lid 20 may be colored in a color close to black. In this case, since the dead bodies of the flying pests accumulated inside the tray unit 10 are difficult to see from above, it is difficult to give an unpleasant impression to the user.

(3) In the above embodiment, it is assumed that one part is colored with the same color for each of the tray part 10 and the lid part 20, but a part of the tray part 10 or the lid part 20 is replaced with the other part. You may color with the same color as a color. For example, in the lid part 20, the attracting structure part 21 can be colored in orange, and the connection part 22 can be colored in the same brown as the tray part 10. In this case as well, an attractive effect similar to that of the flying insect trap 100 of the above embodiment can be obtained.

Regarding the flying pest traps of the present invention, in particular, in order to confirm the influence on the capture performance due to the difference in the color scheme of the flying pest traps, a plurality of flying pest traps having the characteristic configuration of the present invention (Examples 1 to 6) ) Was prepared and a flying insect capture test was conducted. For comparison, a flying pest catcher (Comparative Examples 1 to 5) that does not have the characteristic configuration of the present invention was prepared, and a similar flying pest capture test was performed. In addition, the sum total of the area of the attracting port of the flying insect trap was adjusted to be 960 mm ² in all the examples and comparative examples.

Arranged so that any one of the flying insect traps of Examples 1 to 6 and Comparative Examples 2 to 5 and the flying insect trap of Comparative Example 1 are arranged approximately at the center of the floor surface of the test room of about 25 m ^3. Then 200 Drosophila were released in the test room. After 2 hours, the number of Drosophila captured in each flying pest trap was counted. The capture performance of the flying insect trap was expressed as a capture multiple of Comparative Example 1 based on the number of Drosophila individuals captured by the flying insect trap of Comparative Example 1 (this is 1.0). The flying pest capture test was performed twice, and the average value was obtained. The test results are shown in Table 1.

  As shown in Table 1, the lid and tray parts are L * a * b * color system (CIE 1976) and both have a color tone of L *: 20 or more, a *: 0 or more, b *: 0 or more. In addition, Examples 1 to 6 using the flying pest traps in which at least one of the a * and b * of both had different color tones showed higher capturing performance compared to Comparative Example 1. In particular, the lid part and the tray part have an L * a * b * color system (CIE 1976) and the difference of a * and / or b * is 10 or more, and the lid part is L * a * b *. The color system (CIE 1976) has a color tone of L *: 30 or more, a *: 15 or more, b *: 15 or more, and the tray portion is L * a * b * color system (CIE 1976). *: Examples 1 to 4 using flying insect traps having a color tone of 40 or more, a *: 5 or more, and b *: 5 or more showed higher capturing performance compared to Comparative Example 1.

  As described above, the flying pest traps (Examples 1 to 6) having the configuration of the present invention can exhibit high capture performance against fruit flies such as Drosophila and are useful insect repellent products. confirmed.

  The flying insect trap of the present invention can be suitably used for flying insects, particularly for fruit flies such as Drosophila, flea flies, mushroom flies, mushroom flies, butterflies, but house flies, black flies, yellow flies, powder flies, etc. It can also be used against flies.
