Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to shiitake mushrooms, oyster mushrooms, maitake, bunashimeji, nameko, mushroom,
Culture and cultivation of mushrooms such as enokitake, vegetables, flowers, etc.
Alternatively, in livestock, sericulture, and insect cultivation, the breeding of flies, which occur in the facility and reduce the yield and quality of mushrooms and the like, and are often claimed in the distribution process,
The present invention relates to a method for suppressing the density to a low level efficiently and without relying on a drug that may affect the human body.

[0002]

2. Description of the Related Art In cultivation and cultivation of mushrooms, vegetables, flowers, and the like, or livestock, sericulture, and insect cultivation, which are performed intensively in a house or facility, a fly rots a fungus bed or mushroom fruit body. It is strongly attracted to odors and compost odors, and is also attracted to breeding foods. Moreover, since the life cycle is repeated in a closed system, a large outbreak often occurs. In particular,
It is said that flies that occur during mushroom cultivation, for example, transmit pathogens and mites in adults, and larvae directly harm bacterial beds and fruiting bodies, but not only do they damage the fruiting bodies as commodities. Attach and hide, causing complaints in the distribution process and at retail stores. The use of chemicals as a method of removing these flies is restricted in the case of edible mushroom cultivation, and commercial fly fly ribbons are ineffective, and in electric shock insects using blue fluorescent lights, flies are blue. Although they were attracted to near by fluorescent light, the number of insects actually caught by electric shock was small and the types were limited.

[0003]

DISCLOSURE OF THE INVENTION The present invention has been made in view of the above circumstances, and does not use any chemicals or the like that may affect the edible mushrooms. The purpose was to propose a method of catching flying pests that can keep the species low.

[0004] That is, the environment inside the mushroom cultivation facility is
Mushroom cultivation is carried out at a relatively low temperature of 20 to 25 ° C or lower, and is maintained at a high humidity, such as artificially watering or humidifying, and at a low luminous intensity (2000 Lux or less) that dislikes direct sunlight. Flies generated in the facility are also limited to some extent.

[0005] For example, those which are attracted to a relatively color represented by the family Drosophilidae, mushrooms and flies, and those which are easily attracted to the aroma components represented by the fruit flies, mushrooms, and rugamidae. There is
It is necessary to fully assess the nature of the flies that occur during mushroom cultivation, and to use both efficiently to synergistically kill them.

[0006]

In order to solve the above problems, the present invention has the following arrangement. That is, an attractant for catching flying pests generated in a mushroom cultivation facility, which is characterized by containing an oily or / and aqueous yogurt flavor. A flying insect pest-killing sheet, comprising: an adhesive sheet member having an outer surface coated with an adhesive on part or all of its outer surface; and an attracting mat member impregnated with an attractant. Is a synthetic resin sheet colored with the attraction of flies, and a pressure-sensitive adhesive applied to part or all of the outer surface of the synthetic resin sheet. System (L
L (brightness) is 30 to 7 in transmission color measurement using ab)
The flying pest-killing sheet and the adhesive sheet are characterized in that 0, b (saturation) is in the range of -10 or more, and a part of the flying sheet is provided with a hanging tab. On the other hand, the flying pest-killing sheet, wherein the hole diameter in the horizontal direction is longer than the hole diameter in the vertical direction, is used. For example, a method of catching flying pests that occur in a cultivation facility such as mushrooms, after tearing part or all of the sealing film of the induction mat, characterized in that it is used by attaching to an adhesive sheet. It is a method of catching flying pests.

A pressure-sensitive adhesive sheet in which a pressure-sensitive adhesive is applied to a synthetic resin sheet is installed at a target place, and an attraction mat impregnated with, for example, a fragrance favored by flies is fixed to a part thereof by post-attachment. At the time, because a part of the attraction mat that was sealed in a film with high gas barrier properties is newly opened and attached, the quick action is much faster than the one in which the fragrance was kneaded into the adhesive layer previously seen High, it is possible to kill pests efficiently with its color and fragrance. Further, by applying a color tone utilizing the luminosity of flying pests such as flies, more efficient killing is possible.

This flying insect pest-killing sheet can be used not only for mushroom cultivation but also for livestock such as pigs, cows, birds, sheep, horses, ostriches, and vegetables and flowers such as green onions, tomatoes, cuttles, leaves, and the like. Insect culture (including hydroponic culture), sericulture, beetles, stag beetles, ladybugs, and other insects such as sparrows and crickets. It can be used to control flying pests, especially flies, that come to feeds and the like.

Next, the present invention will be described in detail with reference to the drawings.

FIG. 1 shows an example of handling a flying insect pest-killing sheet of the present invention.
It consists of a synthetic resin sheet 2 and an adhesive 3, and is installed with the cover sheet 4 removed. Further, a hanging tab 5 is provided, which can be used for fixing in a facility, and the tabs 5 can be overlapped and used as shown in FIG. Numeral 6 denotes an attraction mat impregnated with a fragrance favored by flies, which is opened and affixed at the time of setting the adhesive sheet to enhance the attraction effect.

The material of the adhesive sheet is that mushroom cultivation and the like are performed in a high humidity environment using a humidifier or a sprinkler.
In consideration of water resistance, it is desirable to use a synthetic resin or a waterproofed one. Similarly, the pressure-sensitive adhesive is required to have water resistance, and even if it is exposed to water, it is required to recover its adhesive strength when dried.

The color tone is described in, for example, Japanese Utility Model Application Laid-Open No. 56-122381.
Various color tones such as yellow, blue in Japanese Patent Application Laid-Open No. 58-76036, and white in Japanese Patent Application Laid-Open No. 5-30885 have been proposed.

However, when examining the luminosity of flying pests such as flies, for example, they are widely distributed in the visible light range and are not particularly limited. Conversely, the sense of brightness, for example, yellow or green light, It was found that the sensation of feeling similar to human standard relative luminous efficiency (photopic vision) was strong, such as feeling bright and red and blue light being dark. In other words, the adhesive sheet itself does not emit light,
Colors are illuminated by natural light, fluorescent lamps, light bulbs, and the like, so that the brightness and color tone that can be seen through are problematic. Therefore, it is difficult to limit the attractive color by the difference (color) of the wavelength of visible light, and when the attractive color is defined by the brightness, hue, and saturation, a correlation with the attractiveness of the fly was obtained.

That is, when the transmitted color is measured using the Hunter's color system (Lab) (field of view 2 °, standard light C), L (brightness) is 30 to 70 and b (saturation) is -10 or more. If the color is too bright and close to transparent, or if it becomes dark and inconspicuous, flies will not be present and the vividness is more greatly affected than the color attribute.

[0015] The attraction effect of the fragrance is very high, and some of them have been used for hand-made fly traps such as rotten odor of fruit, carrion (fish), miso, etc., but considering their use in mushroom cultivation. , The fragrance itself will rot,
It must not be a source of mold or bacteria and must not cause discomfort to indoor workers.

[0016] Commercially available drugs include attractants for fruit flies, citrus fruit flies, and sea fruit flies, but the effect of attracting flies generated in mushroom cultivation was small.

Further, the fruit flavors such as bananas found in Japanese Patent Application Laid-Open No. 59-156232 were investigated, but none of them had an attracting effect. We found that yogurt flavor is optimal.

As the yogurt flavor, those used for business can be purchased and used. However, food additives added to and contained in confectionery such as candy, jelly, gum and the like, beverages, frozen desserts and the like can be used. It can be selected as appropriate.
Included as fragrance components are direct attraction effects of lactones, esters, fatty acids, ketones, thioethers, phenols, higher aliphatic alcohols, higher aliphatic aldehydes, aromatic alcohols, etc. It is a component that has ethanol, propylene glycol, glycerin,
Components having a volatilizing effect of a solvent such as vegetable oil can be mentioned. As the yogurt flavor, a water-soluble flavor having a high immediate effect and an oily flavor having a long lasting scent can be selected and used in some cases, and these can also be used in combination. Further, an example of the main fragrance component of the yogurt flavor is specifically described as follows.
Methyl butyric acid, cis-3
-Hexenol, Linalool, γ-Dodec
a lactone, Ethyl butyrate,
Diacetyl, Vanilline, Ethyl
Vanilline, Ethylacetoaceta
te, Ione, Linarylatetate,
Ethylhexanoate, trans-2-He
There are xen-1-ylacetate and the like, which work in combination to form an aroma component.

The flying pests to be attracted by the attractant of the present invention are all pests flying in the air, and are particularly suitable for those that explode in an enclosed space, such as flies. Is a typical example. Specific examples include black mushroom fly, mushroom fly, tama fly, drosophila, crane fly and the like.

FIG. 2 shows an example of using the invitation mat. The attraction mat 6 is composed of a mat 7 made of a water-absorbing material and a sealing film 8 having a high gas barrier property, and is sealed by a heat seal 9. It is embedded.

As long as the material of the mat is water-absorbing, there are polymer polymers, ceramics, fibers, foamed plastics, etc., but it is not particularly limited to these materials, but wood pulp and synthetic pulp laminates are relatively inexpensive. This is preferred because it is easy to handle.

The sealing film is preferably made of a material having a high gas barrier property (for example, a laminate of aluminum foil, nylon, polyethylene terephthalate, polyethylene, etc.) so that the fragrance therein does not evaporate. Cut a part of the bag and affix it to the center of the above adhesive sheet.

The fragrance contained in the attracting mat is fast-acting, long-lasting and less wasteful when the flying pest-killing sheet is opened for the first time when used.

The cutting position of the bag can be freely selected.
For example, in the case where water is applied such as water sprinkling, if the lower portion is cut as shown in FIG.

The attraction mat may be individually wrapped or packaged together. For example, the attraction mat is individually wrapped with a highly gas-permeable film having fine holes 11 as shown in FIG. If you put together a plurality of sheets and seal them with a film with high gas barrier properties, when using a flying pest killing sheet, take out the individual packaging invitation mat from the large bag,
It is also possible to eliminate the work of cutting the film simply by sticking it on the adhesive sheet.

Next, the installation of the flying pest killing sheet in the facility is performed using the tab 5 described with reference to FIG. The tab 5 may be attached to any position of the adhesive sheet 1 according to the installation method.

This tab is made of a synthetic resin having a thickness of 0.1 mm to 1.0 mm, and has a long slot for hanging substantially horizontally long with respect to the ground.
About 5.0 cm is practical. The reason why the flying pest killing sheet is made longer in the horizontal direction than in the vertical direction with respect to the ground is to stably fix the flying pest killing sheet. For example, as shown in FIG. If one tab 5 is set, it can be installed stably with little movement due to indoor wind or opening and closing of doors. However, on the ceiling,
Depending on the mode of use, the elongated hole may not be slightly horizontal to the ground, such as when it is hung on a string, a rope, a wire, or the like that is stretched diagonally.

In actual mushroom cultivation, there are many cases in which air conditioning is controlled in the facility, and the air is circulated by turning on / off the cooling / heating and operating the blower fan.
It reaches almost 0m / sec, and it is 1
Wind speeds of up to 2 m / s can be reached.

In such an air-conditioned cultivation, the conventional fly paper has a hanging hole having a circular shape as shown in FIG. 3B or a ring shape as shown in FIG. It only has a simple string, and it winds around the hanging part and swings like a pendulum due to the wind generated in the room,
Many problems occurred after the fly paper was installed, such as the adhesive surfaces being twisted and bound, or falling and sticking to the worker's clothes.

On the other hand, in the flying insect trapping sheet of the present invention, the long hole of the tab can minimize the shaking and can stably maintain the sheet.

In addition, mushroom cultivation uses cultivation shelves and containers for cultivation and arranges mushroom beds in multiple stages to perform intensive production. The flying pest-killing sheet of the present invention is directly provided on the shelves and containers. It is also possible to attach.

In recent years, in the cultivation of mushrooms such as shiitake,
An artificial cultivation method has been developed and widely used, in which after the mycelium has spread in a culture vessel filled with a culture medium, the hyphal-agglomerated culture medium (bacterial bed, artificial log) is taken out of the container and cultivated as a mushroom. For example, FIG. 4 shows an embodiment described in Japanese Utility Model Publication No. 6-16488.
It is practiced to line up 4 and obtain fruiting bodies. The flying pest catching sheet of the present invention may be attached to the shelf frame member 15 or the shelf support member 16. If the cross section of the shelf 17 is L-shaped as shown in FIG. It can be processed according to the shelf material and can be easily and stably mounted.

Next, the effects of the sheet for killing flying pests of the present invention will be specifically described with reference to examples.

[0034]

Examples 1 to 7 and Comparative Examples 1 to 3 A transparent synthetic resin sheet having a size of 20 cm × 30 cm and a thickness of 150 μm coated with an acrylic adhesive was used as an adhesive sheet. The numbers of insect traps of flies associated with the change in color tone were compared by combining the synthetic resin films having the numerical values of (1) and (2).

On another day, the adhesive sheet having the different color tone was used, and as a new test, 0.5 ml of yogurt flavor was adsorbed on a water-absorbent mat of a laminated product of wood pulp and synthetic pulp having a diameter of 4 cm and a thickness of 4 mm. The attracting mat was attached to the center of the adhesive sheet, and the number of insects trapped by the flies due to the change in color tone when the attracting mat was set was compared.

The method of attaching the tub and installing it in the shiitake mushroom cultivation facility was in accordance with FIG.

The number of tests was n = 5 for each item. In the case of sticking the adhesive sheet alone and sticking the yogurt flavor B shown in Table 3, two separate days were installed, and the number of flies trapped was counted. Table 1 shows the results.

[0038]

[Table 1]

First, in the case where only the adhesive sheet is used, it can be seen that the number of insects trapped by Drosophila is extremely small and is not affected by the color tone.

The black fly mushroom has a trapping effect,
The b (saturation) of Comparative Examples 1 to 3 was low, the color tone of a dark image and the number of insects were small although transparent, and the L (lightness) of Examples 1 to 7 was 30 to 70 and the b (saturation) was -10. The above bright ones obtained 2.3 to 7 times the number of insect traps compared to the comparative example, and did not affect the change in a (hue). This tendency was not changed even when the attracting mat (yogurt flavor B) was applied, and it was found that flies represented by the black fly were attracted more strongly to the vividness than the color type (attribute).

Next, the flies represented by Drosophila are clearly shown by the difference between the presence and absence of the attracting mat,
By attaching yogurt flavor, it becomes 32-1
The insect trapping effect increased up to 20 times.

The vivid color tone was also popular among workers in the house, because the more prominent color tone of the pressure-sensitive adhesive sheet makes it easier to identify and does not touch the sheet.

Examples 8 to 10, Comparative Examples 4 to 13, and Control Examples 1 to 2 Next, the difference in the fragrance of the attracting mat was compared with the case of a general commercial fly removing method.

A 10 cm × 60 cm, 100 μ thick synthetic resin colored sheet (yellow, L = 45.8, a = 3.2, b
= 31.9) and fixed on a cultivation shelf as shown in FIG. 5 using an adhesive sheet coated with an acrylic adhesive on one side. The attracting mat was prepared by adsorbing the fragrance shown in each item of Table 2 on a water-absorbing mat (laminated wood pulp) having a diameter of 5 cm and a thickness of 5 mm, and then sealing it by heat sealing as shown in FIG.

At this time, as a sealing film, K nylon 15 / polyethylene 60 having high gas barrier properties and dry laminating were used. At the start of the test, two lower corners were cut off as shown in FIG. Affixed to

The test was conducted in a shiitake mushroom cultivation house where many flies were found, and the number of insects trapped after one day of exposure for each item n = 4 was counted. Table 2 shows the results.

[0047]

[Table 2]

[0048]

[Table 3]

Most of the flies were Drosophila and Drosophila melanogaster, but some of the flies were tamaflies, dragonfly mushrooms, gagbo, midge, and mosquitoes.

The yogurt flavors of Examples 8, 9, and 10 had an extremely large number of flies and insects irrespective of whether they were oily or aqueous. In addition, the oily yogurt flavor had a long lasting scent, and the scent of the invitation mat continued even after one month had passed, and was very popular as a scent that was easy for workers in the house.

In Comparative Examples 4 to 10, the effect of attracting flies was observed mainly on the fruit flavor, but the effect was slightly attracted by the peach flavor.

Comparative Examples 11 and 12 compared commercial attractants of other types of flies, and showed no effect on flies generated by mushroom cultivation. In addition, the case of only the adhesive sheet was used in Comparative Example 13
Shown in

Further, although it is not possible to simply compare, the number of insect traps on the same day of a commercial electric strike insecticide and a commercial fly catching ribbon is shown in Control Examples 1 and 2 as an ordinary insect repelling method.

Using the flying pest killing sheet of the present invention,
With an adhesive sheet having an area of 0 cm × 60 cm and one yogurt flavor attraction mat, an effect similar to that of one electric shock insect killer and 8 to 13 times (per adhesive area) of the fly removing ribbon was obtained.

[0055]

As described above, the flying insect pest-killing sheet of the present invention reduces flies, which are generated in a facility and cause a decrease in the yield and quality of mushrooms and vegetables, to a low density without using pesticides. A yogurt flavor-inducing mat and colored adhesive that efficiently maintain photoreceptors, olfactory organs, and taste organs by thoroughly studying the types and properties of flies generated during mushroom cultivation. When the sheet is newly opened at the time of use, the sheet is very fast-acting, inexpensive, and has a fresh fragrance.

Further, the cover sheet and the hanging tab can be easily attached without soiling the hand with the adhesive surface, and the hole of the tab is longer in the horizontal direction than in the vertical direction with respect to the ground. There is no trouble such as being stably fixed and moving due to the wind in the room, the adhesive surfaces being twisted and bound, and being attached to the clothes of the worker.
