By the way, when the inventors of the present application conducted an attraction test for small flies using the attractant of Patent Document 2, they found that although the attractant of Patent Document 2 has excellent attractability from a relatively long distance, even though it was attracted It has been discovered that some flies fly away without entering the trap. Therefore, there has been a need for an attractant that can reliably attract the flies that have been attracted to the vicinity of the trap further into the trap.

The present invention has been made in view of the above, and its purpose is to draw the flies that are close to the trap into the trap without sacrificing the attractiveness of the flies that are located relatively far away. The goal is to be able to attract people.

In order to achieve the above object, the present invention includes a brewing seasoning derived from rice or rice malt.

The fly attractant for attracting fly flies contains brewed seasonings derived from rice or rice malt, so if the fly attractant is used by storing it in a fly trap, for example, the flies near the trap will be removed. , and are attracted to the inside of the trap by rice or brewed seasonings derived from rice malt.

Since it contains vinegar and alcohol, the attracting effect of the vinegar and alcohol is exerted on the flies that are far away in the comparative example, and the flies that are far away in the comparative example are attracted to the vicinity of the trap.

It is possible to contain vinegar containing aroma components derived from ripened fruits and alcohol containing aroma components derived from flowers obtained by soaking flowers in brewed liquor.

In addition, by containing starch syrup, the effect of attracting fly flies is further enhanced.

Furthermore, by containing citric acid, the effect of attracting fly flies near the trap is further enhanced.

In addition, by diffusing the aromatic components of matured wildflowers into the air, the effect of attracting fly flies is further enhanced.

In addition, by adding katsura wine, which is made by pickling osmanthus flowers to brewed alcoholic fermented rice or grapes, the matured aromatic components of osmanthus will be diffused into the air, making it more effective at attracting fly flies. It increases even more.

Further, water may be added in an amount of 10% to 40% of the total volume of the fly attractant. According to this configuration, the effect of adding water makes it easier for flower-derived aroma components contained in alcoholic beverages to fly, further increasing the effect of attracting fly flies.

Further, the fly trap may include a container containing the fly attractant and having an open opening formed at the top, and a cover member disposed to cover the opening of the container from above. can.

According to this configuration, the cover member is a member that is easy to recognize from flies, and by providing the cover member with a straight edge, contrast is created at the boundary between the surface that is exposed to light and the surface that is in the shadow, and Fly flies are attracted to the part and easily land on the cover member. When a fly lands on a cover member, it becomes easy to enter the inside of the cover member through the entry hole of the cover member due to the attracting effect of the attractant. invaded and was captured.

Furthermore, the cover member is characterized in that it is provided with an intrusion hole for flies and an edge that extends linearly.

According to this configuration, since the entry hole is provided in the planar part of the cover member, for example, a fly that lands on the planar part can easily see the edge of the entry hole and enter into the entry hole. The fly that has entered the entry hole becomes easier to enter the inside of the cover member due to the attracting effect of the attractant, and the fly that has entered the inside of the cover member enters the inside of the container from the open mouth of the container and is captured. Ru.

Further, the cover member is provided with a flat part, and the flat part is provided with an entry hole for fly flies.

According to this configuration, since the entry hole is provided in the planar part of the cover member, for example, a fly that lands on the planar part can easily see the edge of the entry hole and enter into the entry hole. The fly that has entered the entry hole becomes easier to enter the inside of the cover member due to the attracting effect of the attractant, and the fly that has entered the inside of the cover member enters the inside of the container from the open mouth of the container and is captured. Ru.

According to the first invention, since the brewing seasoning derived from rice or rice malt is contained, the fly trap can be used to trap fly flies that are near the trap without sacrificing the attractiveness of flies that are located relatively far away. It can be drawn inside.

According to the second and third aspects of the invention, the effect of attracting fly flies near the trap can be further enhanced.

According to the fourth to sixth inventions, the effect of attracting fly flies located relatively far away can be further enhanced.

Hereinafter, embodiments of the present invention will be described in detail based on the drawings. Note that the following description of preferred embodiments is essentially just an example, and is not intended to limit the present invention, its applications, or its uses.

FIG. 1 is a perspective view of a fly trap 1 according to an embodiment of the present invention, FIG. 2 is a side view of the fly trap 1, and FIG. 3 is a left side view of the fly trap 1. Moreover, FIG. 4 is a longitudinal cross-sectional view of the fly trap 1. As shown in FIG. 4, the fly trap 1 accommodates an attractant S for attracting flies, and includes a container 10 having an opening 10a formed in the upper part, and a container 10 that covers the opening 10a of the container 10 from above. A cover member 20 is provided. The fly trap 1 can be installed and used indoors, for example, in a general home, office, store, factory, or the like. Specifically, it is preferable to install and use it in a place where food is handled, such as a kitchen, but there are no particular restrictions on the installation location, and it should be installed and used as a preventive measure in a place where there are almost no fly flies. be able to. The fly trap 1 can also be called a fly exterminator because it is a device that can capture and exterminate fly flies, and by exterminating fly flies, it can prevent further occurrence of fly flies. Since it is a device, it can also be called a fly prevention device.

Although the dimensions of each part of the fly trap 1 are not particularly limited, for example, the width and depth of the fly trap 1 can be set in a range of about 5 cm to 10 cm. Further, the height of the fly trap 1 can also be set within a range of about 5 cm to 10 cm. The fly attractant S is absorbed into the absorbent liquid E. The liquid absorbent E can be made of something that has the property of absorbing liquid, such as a nonwoven fabric or a sponge, and is housed in the bottom of the container 10. Before using the fly trap 1, the opening 10a of the container 10 is sealed with a liquid-impermeable film (not shown), and the film must be peeled off before use. There is. The absorbent liquid E is not essential and may be omitted.

(Composition of attractant S)
The fly attractant S is a liquid agent for attracting fly flies. As schematically shown in FIG. 6, the fly attractant S is used to attract flies that are in the vicinity of the fly trap 1 (nearby space R1) in which the fly attractant S is accommodated into the fly trap 1. The present invention contains a second attractant that attracts flies located in a distant space that is further away from the fly trap 1 than the nearby space R1 where the attracting effect of the first attractant is significant. The attracting effect of the first attractant is significant around several centimeters to several tens of centimeters around the fly trap 1, and the space near the fly trap 1 is defined as a nearby space R1. Further, the distant space R2, which is farther from the fly trap 1 than the nearby space R1, is several tens of cm or more away from the fly trap 1, and the upper limit is about 1 m to several meters.

The first attractant shows a significant attracting effect in the nearby space R1, but does not show a significant attracting effect in the far space R2. On the other hand, the second attractant shows a significant attracting effect in the far space R2, but does not show a significant attracting effect in the nearby space R1. A significant attracting effect is one in which the presence of an attractant statistically clearly attracts fly flies. For example, when comparing the attraction effect in the nearby space R1, the second attractant is significantly lower than the first attractant, and when comparing the attraction effect in the far space R2, the first attractant is significantly lower than the second attractant. Significantly lower.

The first attractant contains a brewing seasoning derived from rice or rice malt, starch syrup, and citric acid. Brewed seasonings derived from rice or rice malt are seasonings obtained by applying the fermentation effect of rice or rice malt, and can generally be used in cooking. Commercially available starch syrup can be used, and is also called slimy candy or soup candy. Here, candy is a sweet and sticky food made by saccharifying starch or starch-containing raw materials such as rice and sweet potato with malt and acid, and may also be made by boiling down sugar. In addition, citric acid is a carboxylic acid containing a hydroxyl group that exists freely in citrus fruits and is widely distributed throughout the living world.

The reason for mixing the brewing seasoning derived from rice or rice malt, starch syrup, and citric acid to the fly attractant S is that the present inventors conducted experiments and research on various components that attract fly flies in the nearby space R1. It is results-based. That is, by blending the first attractant, the flies that have come to the space R1 near the fly trap 1 can be effectively attracted into the fly trap 1 and captured.

The second attractant contains alcohol and vinegar. Specifically, it contains liquor containing aroma components derived from flowers obtained by soaking flowers in brewed liquor, and vinegar containing aroma components derived from ripened fruits. An example of the alcoholic beverage constituting the second attractant is a mixed alcoholic beverage (Keikazake) made by soaking and aging Osmanthus flowers in a brewed alcoholic beverage made by alcohol-fermenting rice or grapes with yeast. Therefore, Katsura Flower Sake contains aroma components derived from flowers obtained by ripening Osmanthus flowers. As a brewed alcoholic beverage, white wine made from green grapes is preferred. White wine contains aromatic components obtained from ripening grapes, and since it is a brewed alcoholic beverage, unlike distilled alcoholic beverages, it also contains yeast. For example, Japanese sake is preferable as a brewed liquor made by alcohol-fermenting rice.

An example of the vinegar constituting the second attractant is brewed vinegar made from the fruit of the Yamasako tree (Yamasako vinegar). Therefore, Sansako vinegar contains aroma components derived from the fruit called Sansako, which is obtained by ripening the fruit.

The reason why the fly attractant S is mixed with the Sansako vinegar and the Katsura wine is based on the results of experiments and research conducted by the present inventors on various components that attract fly flies in the distant space R2. That is, in general, vinegar and alcohol have moderate transpiration properties and are therefore suitable as attractants for attracting insects from a distance, but among them, the combination of Sansako vinegar and Keika wine is particularly excellent in attracting fly flies. Sansako vinegar and Keika wine can be mixed at a volume ratio of 1:1, but the mixing ratio may be varied, for example, within the range of 4:6 to 6:4.

The fly attractant S may contain an insecticide. Insecticides have traditionally been used to kill fly flies, and are almost odorless chemicals. Examples of insecticides include dinotefuran and the like. The fly attractant S may contain a salt. Salt can be added for preservative purposes. The fly attractant S may contain water. That is, water may be added in an amount ranging from 10% to 40% of the total volume of the fly attractant S. By containing water, the water-added effect makes it easier for the flower-derived aroma components contained in the sake to fly, further increasing the effect of attracting fly flies. The fly attractant S may contain an antibacterial agent or a fungicidal agent, and examples of such agents include Amolden FS-14D.

(How to use fly trap 1)
The fly trap 1 is used by attaching the cover member 20 to the container 10 after peeling off the film sealing the container 20. When the fly trap 1 is placed on a stand or floor, the fly attractant S transpires at room temperature, resulting in the upper entry port 21a, front entry port 22a, back entry port 23a, left entry port 24a, and right entry port 25a. The particles then scatter outward from the cover member 20. The fly attractant S may be dispersed over a wide area by the convection of the surrounding air.

The flies in the distant space R2, which is away from the fly trap 1 shown in FIG. 6, approach the fly trap 1 by being attracted by the second attractant containing Katsura flower wine and Sansako vinegar. The flies in the nearby space R1 are attracted by the first attractant containing brewing seasoning derived from rice or rice malt, starch syrup, and citric acid, and enter the upper entry port 21a, the front entry port 22a, and the back entry port. It enters the inside of the cover member 20 through the opening 23a, the left side entrance 24a, and the right side entrance 25a. The flies that have invaded the interior of the cover member 20 enter the interior of the container 10 through the opening 10a of the container 10, and are exterminated by the insecticide contained in the fly attractant S.

(Small scale efficacy test results)
A chamber of 70 cm x 70 cm x 70 cm was prepared, and the inside of this chamber was used as a test space. The temperature during the test was 25°C plus or minus 3°C, and the humidity was 75% plus or minus 5%.

The test method is as follows. First, a fixative (a piece of orange) is placed in the above-mentioned chamber, which is maintained at humidity using the saturated salt method, and 20 Drosophila melanogaster flies are released. After the flies have settled, the colonizer is placed at a corner of the bottom of the chamber, and the fly trap 1 is placed at a corner diagonally opposite to the colonizer on the bottom of the chamber. After 18 hours, the number of flies caught by the fly trap 1 is measured.

Table 1 shows the formulation of the fly attractant according to Comparative Example 1.

Table 2 shows the formulation of the fly attractant according to Comparative Example 2.

Table 3 shows the formulation of the fly attractant according to Example 1.

In Tables 2 and 3, the first attractant includes a brewing seasoning derived from rice or rice malt, starch syrup, and citric acid. In the first attractant, the content of starch syrup is about 70 wt%, and the rest is a brewing seasoning derived from rice or rice malt and citric acid. However, the content of starch syrup can be adjusted as appropriate. The ratio of the brewing seasoning derived from rice or rice malt to citric acid can be set arbitrarily, and for example, the weight ratio can be in the range of 1:99 to 99:1.

If the number of fish caught using the recipe of Comparative Example 1 was 100, the number of fish caught using the recipe of Comparative Example 2 was 120, and the number of fish caught using the recipe of Example 1 was 188. In this way, by including the first attractant in the second attractant (in this example, Sansako vinegar and Keika wine), the attracting effect on a small scale is significantly enhanced. However, as in the case of Comparative Example 2, on a small scale, even the first attractant alone (without the second attractant) exhibits a better attracting effect than the second attractant. Note that the content of the first attractant is not limited to 4.68 g, and a significant effect can be exerted even if the content is greater or less than this. For example, the lower limit of the content of the first attractant may be set to 2 g, and the upper limit may be set to about 10 g.

(Large scale efficacy test results)
A room with an area of 8 tatami mats was prepared, and the interior of this room was used as a test space. The temperature at the time of the test was normal temperature, and the humidity was normal.

The test method is as follows. First, a fixing substance (a piece of orange) is placed in the room, and a large number of Drosophila melanogaster and Drosophila melanogaster are allowed to settle there. Thereafter, the fly trap 1 containing the fly attractant of Example 1 and the fly catcher 1 containing the fly attractant of Comparative Example 1 were placed at a place equidistant from the fixed object, and the number of flies caught after several minutes to several hours was counted. It was measured.
As a result, when the number of fish caught using the recipe of Comparative Example 1 was 100, the number of fish caught using the recipe of Example 1 was 168. In this way, when the first attractant is contained in the second attractant (in this example, Sansako vinegar and Keikashu), the attracting effect is significantly enhanced even on a large scale.

Next, the results of comparing the prescriptions of Comparative Example 1 and Comparative Example 2 using the same method will be explained. If the number of fish caught using the recipe of Comparative Example 1 was 100, the number of fish caught using the recipe of Comparative Example 2 was 8. Thus, on a large scale, the first attractant alone exhibits almost no attracting effect.

Based on the above small-scale and large-scale test results, the second attractant is superior in attracting flies from a relatively long distance, but is inferior to the first attractant in attracting flies from a short distance. I can say it. It can be said that the first attractant is inferior in attracting flies from a relatively long distance, but is superior to the first attractant in attracting flies from a short distance. Therefore, by containing the first attractant and the second attractant, flies that are far away (far space R2) are attracted by the second attractant, and flies that come closer (fly that has entered the nearby space R1) are attracted. can be reliably attracted into the fly trap 1 by the first attractant.

Next, each component of the first attractant will be explained. As mentioned above, the first attractant contains a brewing seasoning derived from rice or rice malt, starch syrup, and citric acid, and the content of starch syrup is about 70 wt%. Therefore, in terms of quantity, starch syrup is the main ingredient, but even when starch syrup was added to the formulation of Comparative Example 1, no improvement in the attracting effect could be confirmed. Furthermore, citric acid is a nonvolatile and odorless substance, and has no attracting effect on its own. Therefore, the main attractant component in the first attractant is a brewed seasoning derived from rice or rice malt. By blending starch syrup and citric acid with this, the viscosity and pH are appropriately set, and the attracting effect of the brewing seasoning derived from rice or rice malt is maximized.

(Shape comparison test 1 of fly traps)
As a comparative example container, a cylindrical container with an open top was prepared. As a container of an example, a container having a rectangular cylindrical shape with a square cross section and an open top was prepared. The comparative container has no straight edges, only curved edges. Since the container of the example has a rectangular tube shape, it has a vertically extending edge and a horizontally extending edge. The container of the comparative example and the container of the example were both black in color, and had the same height and maximum outer diameter. Inside the container of the comparative example and the container of the example, a fly attractant having the formulation of Example 1 shown in Table 2 was contained, respectively. An adhesive spray was applied to the surface of the container, and the number of Drosophila melanogaster adhering to the adhesive surface was measured. This is to compare the ease with which flies land on the surface of the container.

A room with an area of 8 tatami mats was prepared, and the interior of this room was used as a test space. The temperature at the time of the test was normal temperature, and the humidity was normal. The illumination intensity was set at approximately 230 Lux, assuming the level of light in everyday spaces. The test insects were Drosophila melanogaster and Drosophila melanogaster. The test was conducted twice.

In the container of the comparative example, the number of catches was 79, while in the container of the example, the number of catches was 98. In this way, by using a container with a straight edge, the attracting effect can be improved even if the fly attractant is the same. In other words, it is thought that by providing a container with a linear edge, a contrast is created at the boundary between the light-exposed surface and the shaded surface, and that flies are attracted to this area and are more likely to land on the container.

(Shape comparison test 2 of fly traps)
As a comparative example, a container was prepared in which a cover member curved upward was provided at the top and a rectangular entry opening was provided near the center of the cover member. As a container of the example, a container was prepared in which a cover member having a substantially horizontal plane portion was provided on the upper part, and a rectangular entry hole similar to that of the comparative example was provided near the center of the cover member. The cover member of the comparative example and the cover member of the example were both black in color and had the same size. Inside the container of the comparative example and the container of the example, a fly attractant having the formulation of Example 1 shown in Table 2 was contained, respectively.

In addition, in this test, the entry port was only provided on the top surface and not on the side surface. Therefore, the contrast is not affected by side edges and shadows. Also, unlike the above test, no adhesive was provided on the surface, allowing the flies that landed to further infiltrate the interior through the entrance. In other words, this is a test to compare the ease of intrusion into the interior through the entrance on a curved surface and a flat surface.

A room with an area of 8 tatami mats was prepared, and the interior of this room was used as a test space. The temperature at the time of the test was normal temperature, and the humidity was normal. The test insects were Drosophila melanogaster and Drosophila melanogaster. The test was conducted once.

In the container of the comparative example, the number of catches was 33, while in the container of the example, the number of catches was 114. In this way, by providing the penetration hole in the flat part, the attracting effect can be improved even if the fly attractant is the same. The reason for this is unknown, but for flies that land on a bay surface, the edge of the entry hole is beyond the horizon and difficult to see, whereas for flies that land on a flat surface, the edge of the entry hole is easier to see. It is thought that it becomes easier to enter the penetration hole.

(Operations and effects of embodiments)
As explained above, according to this embodiment, since the edges 30 to 37 extending linearly are provided on the cover member 20, the shape of the cover member 20 can enhance the effect of attracting fly flies. can improve the catch rate.

Further, since the penetration hole 21a is provided in the flat part 21 of the cover member 20, the shape of the cover member 20 can enhance the effect of attracting the flies, thereby improving the rate of catching the flies.

It also contains vinegar containing aroma components derived from ripened fruits, sake containing aroma components derived from flowers obtained by soaking flowers in brewed liquor, and brewed seasoning derived from rice or rice malt. Therefore, the flies near the fly trap 1 can be attracted to the interior of the fly trap 1 without sacrificing the attractiveness of flies located relatively far away. In particular, by containing a first attractant that acts on a nearby space and a second attractant that acts on a distant space, the attracting effect can be enhanced over a wide range.

The embodiments described above are merely illustrative in all respects and should not be interpreted in a limiting manner. Furthermore, all modifications and changes that come within the scope of equivalents of the claims are intended to be within the scope of the present invention.

For example, as in Modification 1 of the embodiment shown in FIGS. 7 and 8, it is not necessary to form a recess in the cover member 20. This simplifies the shape of the cover member 20, but since it has linear edges 30 to 37 and the entry port 21a can be provided in the upper surface portion 21, which is a flat surface, for example, it is possible to provide the cover member 20 with a simple shape. It can increase the effectiveness of catching flies.

Further, as in a second modification of the embodiment shown in FIG. 9, each entry port 24a (only the left side is shown) may have a circular shape. Further, although not shown, the entrance may be in the shape of an ellipse, an oval, a slit, or a polygon such as a triangle, pentagon, or hexagon. Furthermore, all the entry ports may have the same shape and size, or may have different shapes and sizes. Further, for example, a plurality of entry ports may be provided in the upper surface portion 21 or the like.

Further, the cover member 20 may have a shape close to a cube or a shape close to a rectangular parallelepiped. Further, the cover member 20 may have a rectangular tube shape having a pentagonal horizontal cross section, or a rectangular tube shape having a hexagonal horizontal cross section, for example.

As explained above, the present invention can be used, for example, to capture flying flies indoors.
