Description

TECHNICAL FIELD The present invention relates to a flying pest control product for garbage containers that suppresses the propagation of flying pests in the inner space of the garbage container.

Various products are commercially available for the purpose of controlling flying pests such as flies. In order to properly control flying pests, various active ingredients such as repellent and insecticidal ingredients against flying pests are required. The use of highly safe active ingredients is being considered.

For example, a spray agent for controlling small flies using natural pyrethrin, which is highly safe for humans and animals, has been developed (see, for example, Patent Document 1). The product of Patent Document 1 enhances the insecticidal effect by blending a pyrethroid-based insect repellent component in addition to natural pyrethrin.

Also, a flying insect repellent tool using a polyether compound as a repelling component against flying insects has been developed (see, for example, Patent Document 2). The product of Patent Document 2 enhances the repelling effect against flying pests by blending a pyrethroid drug and a plant essential oil in addition to the polyether compound in the flying pest repellent. The flying pest repellent can be volatilized over a long period of time by accommodating the flying pest repellent in a container body and closing the upper surface with a gas permeable film.

Drosophila, flea flies, etc. are likely to be generated from trash cans with lids (hereinafter referred to as "garbage containers") where raw food waste is discarded. A product that suppresses the propagation of flying pests in the environment is desired. In order to suppress the propagation of flying pests in a garbage container, it is necessary to keep the insecticidal component, the repellent component, etc. at an appropriate concentration for a long period of time in the internal space of the garbage container.

The product of Patent Document 1 is a spray agent that directly controls incoming flying pests, and is not a product intended to retain the blended natural pyrethrins and pyrethroid-based insect repellent ingredients for a long period of time.

The product of Patent Document 2 does not consider the difference in permeability with respect to gas-permeable films such as polyether compounds, pyrethroid drugs, and plant essential oils blended in flying insect repellents, and each component has an appropriate concentration. There is a risk that it will not be volatilized in

As described above, the current products have much room for improvement in terms of keeping the active ingredient at an appropriate concentration for a long period of time in order to suppress the propagation of flying pests in the inner space of the garbage container. The present invention has been made in view of the above problems, and is intended to prevent flying pests, particularly flying pests typified by fruit flies such as fruit flies, flea flies, blackfly flies, mushroom flies, and moth flies. It is an object of the present invention to provide a product for controlling flying insect pests for garbage containers that can suppress breeding in space.

The characteristic configuration of the flying pest control product for garbage containers according to the present invention for solving the above problems is as follows:
A flying pest control product for a garbage container that suppresses propagation of flying pests in the internal space of the garbage container,
an insecticidal component carrier carrying an insecticidal component that kills flying pests;
an antibacterial component carrier that carries an antibacterial component that suppresses the growth of bacteria on the surface of the garbage;
a main body on which the insecticidal component carrier and the antibacterial component carrier are installed;
a cover part mounted so as to cover the insecticidal component carrier and the antibacterial component carrier;
with
The cover part has an insecticidal component releasing part for releasing the insecticidal component into the internal space and an antibacterial component releasing part for releasing the antibacterial component into the internal space in different sizes and in different regions. That's what it is.

According to the flying pest control product for a garbage container of this configuration, the cover portion has the insecticidal component releasing portion and the antibacterial component releasing portion in different regions with different sizes, so that the insecticidal components are carried by different carriers. and the antibacterial component can volatilize at appropriate concentrations according to their volatilities. For this reason, the insecticidal component and the antibacterial component are maintained at effective concentrations in the internal space of the garbage container, and the insecticidal component not only kills the flying pests that enter the internal space, but also prevents the propagation of bacteria on the surface of the garbage. The antibacterial component suppresses the generation of rotten odors and prevents flying pests from approaching. As a result, breeding of flying pests in the internal space of the garbage container can be suppressed.

According to the flying pest control product for a garbage container of this configuration, the area ratio Sa/Aa is configured to be 0.5 to 0.9, so that the opening area Sa of the insecticidal component releasing part is small and the insecticidal component is sufficiently released. It is not necessary to increase the size of the main body to secure the installation area Aa of the insecticidal component carrier, and the insecticidal component with relatively low volatility can be volatilized appropriately in the internal space of the garbage container. In addition, since the area ratio Sb/Ab is configured to be 0.1 to 0.7, it is necessary to increase the size of the main body in order to secure the installation area Ab of the antimicrobial component carrier, and a sufficient amount of antimicrobial component carrier. It is not necessary to increase the thickness of the antibacterial component-carrying member to hold the body, and the antibacterial component-carrying member can carry a sufficient amount of the antibacterial component. Therefore, the flying pest control product for a garbage container of this configuration does not get in the way even if it is installed in the internal space of the garbage container, and is convenient to use.

The antibacterial component is at least one selected from the group consisting of thymol, linalool, terpineol, benzyl acetate, citral, citronellal, tetrahydrolinalool, dihydromyrcenol, 2-transhexenal, iso-E-super, and estragole. It is preferably an antibacterial fragrance containing.

According to the flying pest control product for garbage containers of this configuration, since the appropriate antibacterial fragrance is used as the antibacterial component, the growth of bacteria on the surface of the garbage contained in the garbage container is suppressed, It is possible to prevent garbage from rotting. As a result, it is possible to suppress the generation of offensive odors and the generation of substances that attract flying insects due to putrefaction of garbage, and prevent the arrival of flying insects.

In the flying pest control product for garbage containers according to the present invention,
The insecticidal component is preferably a pyrethroid insecticidal component.

According to the product for controlling flying insects for garbage containers of this configuration, a pyrethroid-based insecticidal component is used as the insecticidal component, so that a good insecticidal effect can be obtained.

In the flying pest control product for garbage containers according to the present invention,
It is preferably attached to the inside of the garbage container or hung from the inside of the garbage container so as to face the garbage accommodated in the internal space.

According to the flying pest control product for a garbage container of this configuration, the insecticidal component and the antibacterial component can be combined in a garbage container with a lid by attaching it to the inside of the garbage container or by hanging it from the inside of the garbage container. effective concentration can be maintained.

A carrying antibacterial component carrier 40 is installed. A concave attachment portion 15 is further formed at the bottom of the carrier installation portion 13 . As shown in FIG. 1(b), the bottom of the sticking portion 15 is formed to the same depth as the edge portion 12, and the flying pest control product 100 for the garbage container is attached to the back of the bottom of the garbage container 200. As shown in FIG. An affixing member 50 is affixed for fixing to.

The cover part 20 has a pedestal part 21 and an edge part 22, and is attached to the main body 10 so that the pedestal part 21 covers the insecticidal component carrier 30 and the antibacterial component carrier 40 installed on the main body 10. be. The platform portion 21 includes an insecticidal component release portion 23 for releasing the insecticidal component into the internal space S of the trash container 200, and an antibacterial component release portion 24 for releasing the antibacterial component into the internal space S of the trash container 200. are provided in different regions with different sizes. Further, as shown in FIG. 1(a), the cover portion 20 is provided with a pressing portion 25 for fixing the insecticidal component carrier 30 installed on the main body 10 when the cover portion 20 is attached to the main body 10. As shown in FIG.

The insecticidal component release portion 23 is an opening formed at a position facing the insecticidal component carrier 30 installed in the carrier installing portion 13 when the cover portion 20 is attached to the main body 10 . The insecticidal component volatilized from is discharged into the internal space S of the garbage container 200. - 特許庁In this embodiment, the insecticidal component release part 23 is divided into a plurality of openings by the pressing part 25, and is composed of three openings in FIG. 1(a). The opening area of the insecticidal component release portion 23, which is the sum of the areas of the plurality of divided openings, is preferably 1 to 49 cm ² , more preferably 4 to 36 cm ² , and still more preferably 9 to 25 cm ² . be. The antibacterial component release portion 24 is an opening formed at a position facing the antibacterial component carrier 40 installed in the carrier installation portion 14 when the cover portion 20 is attached to the main body 10 . The antibacterial component volatilized from the waste container 200 is released into the internal space S of the waste container 200 . In this embodiment, the antibacterial component used has a higher vapor pressure at 20° C. than the insecticidal component, and the period during which the insecticidal component volatilizes at an effective concentration and the period during which the antibacterial component volatilizes at an effective concentration are used. , the opening area of the antibacterial component releasing portion 24 is configured to be smaller than the opening area of the insecticidal component releasing portion 23 .

The rate is slow, and there is a risk that a sufficient amount of the antibacterial component cannot be released from the beginning of use.

[insecticidal component carrier, antibacterial component carrier]
The insecticidal component carrier 30 is an absorbent carrier impregnated with a chemical. For the carrier, for example, pulp nonwoven fabric or felt can be used. In order to increase the thickness of the carrier, a plurality of thin pulp nonwoven fabrics or felts may be laminated. Pulp non-woven fabrics and felts can be spunlaced to form a web on the surface or embossed in order to efficiently absorb the drug while retaining their shape. Instead of pulp nonwoven fabric or felt, the carrier may be composed of liquid-absorbing sponge, paper, fiber assembly, or the like. The drug contains an insecticidal component that kills flying pests. As the insecticidal component, a pyrethroid-based insecticidal component that is volatile at room temperature is used. Here, "having volatility at room temperature" means exhibiting a vapor pressure of 0.001 Pa or more at 25°C, and if the amount of volatilization is 0.005 mg/hr or more, it is volatile at room temperature. can be considered to have Such pyrethroid insecticidal components include, for example, transfluthrin, metofluthrin, profluthrin, empentrin, and the like, and profluthrin is particularly preferably used. These pyrethroid-based insecticidal components can be used alone, but may be used in the form of a mixture of two or more. Some pyrethroid insecticidal components have optical isomers or geometric isomers based on an asymmetric carbon in the acid or alcohol moieties. , or mixtures of isomers in any ratio can be used.

The insecticidal component carrier 30 is configured in a shape corresponding to the space formed between the carrier installation portion 13 of the main body 10 and the pedestal portion 21 of the cover portion 20 . In the flying pest control product 100 for garbage containers, the insecticidal component release part 23 is formed larger than the antibacterial component release part 24, and the volatilizing surface 30V of the insecticidal component carrier 30 is larger than the volatilizing surface 40V of the antimicrobial component carrier 40. It is possible to configure a large area. Therefore, as shown in FIG. 1(b), even if the thickness Ta of the insecticidal component carrier 30 is smaller than the thickness Tb of the antibacterial component carrier 40, it is possible to carry a sufficient amount of medicine. The flying pest control product for a garbage container ¹⁰⁰ has ^an area ratio Sa/ Aa is preferably comprised between 0.5 and 0.9, more preferably between 0.5 and 0.7. When the area ratio Sa/Aa is 0.5 to 0.9, the insecticidal component with relatively low volatility is appropriately volatilized in the internal space S of the garbage container 200, and the flying pest control product 100 for the garbage container is produced. It is possible to prevent an increase in size. If the area ratio Sa/Aa is less than 0.5, there is a risk that the opening area Sa of the insecticidal component release part 23 is too small to sufficiently release the insecticidal component, or that the flying pest control product for a garbage container is used to secure the installation area Aa. 100 becomes large, and there is a possibility that usability may deteriorate. If the area ratio Sa/Aa is greater than 0.9, the carrier mounting portion 13 may not be sufficiently fixed by the cover portion 20, and the carrier mounting portion 13 may fall off.

Similar to the insecticidal component carrier 30, the antibacterial component carrier 40 is an absorbent carrier impregnated with a drug. In the antibacterial component carrier 40, the agent impregnated into the carrier contains an antibacterial component and a plant-derived volatile component having a repelling effect against flying pests. As the antibacterial component, an antibacterial fragrance having volatility at room temperature is used. Such antimicrobial fragrances include, for example, thymol, linalool, terpineol, benzyl acetate, citral, citronellal, tetrahydrolinalool, dihydromyrcenol, 2-transhexenal, iso-E-super, and estragole. These antibacterial fragrances can be used alone, but may be used in the form of a mixture of two or more. In particular, a mixture of thymol, linalool, terpineol and benzyl acetate is preferably used. By volatilizing these antibacterial fragrances and releasing them into the internal space S of the garbage container 200, the propagation of bacteria adhering to the garbage contained in the garbage container 200 is suppressed, and the garbage is putrefied (altered). can be prevented. As a result, it is possible to suppress the generation of offensive odors and the generation of substances that attract flying insects due to decomposition of raw garbage, etc., and prevent the approach of flying insects. As the plant-derived volatile component, a plant-derived volatile substance that is volatile at room temperature and is induced by natural enemies of herbivores is used. Examples of such plant-derived volatile components include cis-3-hexenol, cis-jasmon, d-limonene, linalool, l-menthol, and methyl salicylate. In particular, a mixture of cis-3-hexenol, cis-jasmone, d-limonene, linalool, l-menthol and methyl salicylate is preferably used. Although the plant-derived volatile components can be used alone, they may be used in the form of a mixture of two or more. These plant-derived volatile components have a repellent action against flying pests using biological interactions. It is known that the volatile substances induced by herbivore damage and released from plants attract natural enemy organisms of herbivores. It is known to have a repellent effect on individuals of the same species. In addition, it is known that exposure to plant volatiles induced by natural enemies of herbivores leads to reduced fecundity and fecundity of herbivores. Furthermore, it has been reported that natural enemy organism-induced plant volatiles of a herbivore induced by damage by a certain herbivore also show a repellent effect on another species of herbivore. These repellent actions are considered to be natural laws to avoid predation by natural enemies of herbivores and to avoid competition for resources among herbivores. The medicament may further contain retention ingredients such as kerosene, glycols, glycol ethers, and the like. By including the retention component, the efficacy of the drug can be exhibited over a long period of time.

The antibacterial component carrier 40 is configured in a shape corresponding to the space formed between the carrier installation portion 14 of the main body 10 and the pedestal portion 21 of the cover portion 20 . ^The flying pest ^control product 100 for a garbage container has an area ratio Sb/ Ab is preferably comprised between 0.1 and 0.7, more preferably comprised between 0.2 and 0.5. If the area ratio Sb/Ab is 0.1 to 0.7, the size of the flying pest control product 100 for garbage containers can be increased while allowing the carrier to carry a sufficient amount of the antibacterial component and the plant-derived volatile component. can be prevented. If the area ratio Sb/Ab is less than 0.1, the size of the flying pest control product 100 for a garbage container is increased in order to secure the installation area Ab, which may deteriorate usability. If the area ratio Sb/Ab is greater than 0.7, the thickness of the carrier needs to be increased in order to retain a sufficient amount of the drug, and the increase in the thickness of the flying pest control product 100 for a garbage container may deteriorate usability. There is

[Confirmation test for attracting flies]
Using odorous substances (ammonia, amines, and methyl mercaptan), a test to confirm the effect of attracting small flies was carried out. An acrylic cylinder (inner diameter: 20 cm, height: 20 cm) was prepared for each odorant, and each cylinder was placed on a blank sheet of paper. Two plastic cups with lids (inner diameter: 101 mm, height: 44 mm) were placed upside down in each cylinder, and a piece of cut cotton was placed on both lids and impregnated with 2 g of a 3% aqueous solution of balsamic vinegar. After that, absorbent cotton to which 1 mL of an odorant was added was placed side by side on one of the lids to form a malodor treatment area. Plastic cups with entry holes (2 mm in diameter, 5 pieces) provided on the bottom surface were turned upside down and placed on top so as to match each lid. After closing the top of the acrylic cylinder with a stocking, fruit flies were released into the cylinder. . The number of test insects (landing number) that invaded each cup over time was counted, and the attracting performance of the offensive odor treatment area was evaluated based on the relative ratio to the untreated area. The landing numbers and relative ratios are shown in Table 2.

The addition of any of ammonia, amines, and methyl mercaptan increased the number of Drosophila landings, confirming that these odorants have an effect of attracting fruit flies.

[Foul odor suppression effect confirmation test]
In order to confirm the odor suppression effect against odorous substances (ammonia, amines, and methyl mercaptan) that have been confirmed to attract flies, a malodor suppression effect confirmation test was carried out using various food materials assumed to be garbage. A drug-treated section and an untreated control section of Examples 1-3 were prepared for each food material, and the drug-treated section and untreated control section of Examples 1-3 were stored at room temperature (25° C.) for one week. The drug-treated plots and non-treated control plots in Examples 1 to 3 were the same as those used in the alteration inhibition effect confirmation test. One week after the start of the test, odorants (ammonia, amines, and methyl mercaptan) were measured using gas detector tubes (manufactured by GASTEC Co., Ltd.) in each of the drug-treated area and the untreated control area of Examples 1 to 3. ) was measured, and the odor suppression rate (%) was determined by the following formula.
Offensive odor control rate (%) = (Cc - Tc)/Cc x 100
Tc: Odor substance concentration (ppm) in the chemical treatment area
Cc: Odor substance concentration (ppm) in untreated control plot
Table 3 shows the concentration of odorous substances in the untreated control section, and Table 4 shows the odor suppression rate for each food type.

When pork, shiitake mushrooms, dried sardines, and cheese were used, ammonia was not detected in any of the drug-treated plots of Examples 1 to 3 and the non-treated control plot. In the other foodstuffs, the bad odor suppression rate of ammonia was 67% or more in Example 1, 84% or more in Example 2, and 75% or more in Example 3. Amines were not detected in any of the drug-treated plots of Examples 1 to 3 and the untreated control plot when pork and shiitake mushrooms were used. In the other food materials, the odor suppression rate of amines was 80% or more in Example 1, 75% or more in Example 2, and 70% or more in Example 3. Methyl mercaptan was not detected in any of the drug-treated plots of Examples 1 to 3 and the untreated control plot when cheese was used. In the other foodstuffs, the malodor suppression rate of methyl mercaptan was 93% or more in Example 1, 90% or more in Example 2, and 94% or more in Example 3. From the above results, it was confirmed that the products for controlling flying pests for garbage containers of Examples 1 to 3 were effective in suppressing offensive odors for all of ammonia, amines, and methyl mercaptan. In particular, the malodor suppression rate of methyl mercaptan is as high as 93% or more in Example 1, 90% or more in Example 2, and 94% or more in Example 3, regardless of the food ingredients. It was confirmed that the flying insect control product for garbage containers strongly suppresses the generation of methyl mercaptan.

[Sensory test 1]
Sensory test 1 below was conducted in order to confirm the effect of suppressing offensive odors by the product for controlling flying insects for garbage containers. Five plastic cylinders (inner diameter 20 cm, height 43 cm) were prepared, each containing pork and squid and a small amount of water, and covered with a glass plate on top. After containing the food and water, the glass plate was pasted with the flying insect pest control product of Example 1 on the inside of the glass plate, and the glass plate was pasted with the flying insect pest control product of Example 2 on the inside of the glass plate. , the glass plate with the flying pest control product for garbage containers of Example 3 attached, and the glass plate with the flying pest control product for garbage containers of Comparative Example 1 attached to the inside, respectively. Examples 1 to 3 and Comparative Example 1 were treated with chemicals. After the foodstuffs and water were contained, the glass plate was placed on the container and the lid was kept on. After storing these plastic cylinders at room temperature (25° C.) for one week, the odor inside the cylinders was evaluated by nine monitors using a six-level odor intensity display method. The evaluation criteria of the 6-step odor intensity indication method are "0: no odor", "1: barely perceptible odor", "2: weak odor that makes it possible to identify what it is", "3: easily perceptible odor", " 4: strong odor" and "5: strong odor".

As a result of the sensory test 1, the average evaluation of the drug-treated plots of Example 1 was 2.4, the average evaluation of the drug-treated plots of Example 2 was 2.5, and the average evaluation of the drug-treated plots of Example 3 was The average was 2.8, the average evaluation of the drug-treated plot in Comparative Example 1 was 2.9, and the average evaluation of the non-treated control plot was 4.7. From the above results, it was confirmed also in the sensory test that the products for controlling flying insects for garbage containers of Examples 1 to 3 had an excellent odor suppressing effect.

[Sensory test 2]
Sensory test 2 below was carried out in order to confirm the effect of suppressing offensive odors when a certain period of time had passed since the product for controlling flying insects for garbage containers was installed. Three plastic cylinders (inner diameter: 20 cm, height: 43 cm) were prepared, and a glass plate was placed on the top to cover the cylinder. A glass plate with the flying pest control product for garbage containers of Example 1 attached to the inside thereof, and a glass plate with the flying pest control product for garbage containers of Comparative Example 2 attached to the inside of the glass plate of Example 1 and This was used as the drug-treated section of Comparative Example 2. A non-treated control was obtained by placing a glass plate on it and keeping the lid on. After storing these plastic cylinders at room temperature (25° C.) for 19 days, pork and squid and a small amount of water were placed in each plastic cylinder and stored at room temperature (25° C.) for one week. One week after the foodstuffs and water were stored, the odor inside the cylinder was evaluated by 8 monitors according to the 6-level odor intensity display method. The evaluation criteria of the 6-step odor intensity indication method are "0: no odor", "1: barely perceptible odor", "2: weak odor that makes it possible to identify what it is", "3: easily perceptible odor", " 4: strong odor" and "5: strong odor".

As a result of sensory test 2, the average evaluation of the drug-treated group in Example 1 was 2.8, the average evaluation of the drug-treated group of Comparative Example 2 was 3.4, and the average evaluation of the untreated control group was was 4.6. From the above results, it was confirmed that the product for controlling flying insects for garbage containers of Example 1 had an excellent odor suppressing effect even in sensory test 2 in which time had elapsed since installation. In Comparative Example 2, in which the insecticidal and antibacterial components are the same as those in Example 1, the bad odor suppressing effect is inferior because the area ratio Sa/Sb between the insecticidal component-releasing portion and the antibacterial component-releasing portion is 1, and the antibacterial component-releasing portion is It is thought that the antibacterial component was released at an early stage after installation due to the relatively large formation, and the effect of the antibacterial component did not last.

[Confirmation test for inhibitory effect on attracting small flies]
We conducted tests to confirm the effect of inhibiting the attraction of small flies to various foodstuffs that are assumed to be raw garbage. Adult fruit flies and adult flea flies were used in the test. A drug-treated section and an untreated control section of Examples 1-3 were prepared for each food material, and the drug-treated section and untreated control section of Examples 1-3 were stored at room temperature (25° C.) for one week. The drug-treated plots and non-treated control plots in Examples 1 to 3 were the same as those used in the alteration inhibition effect confirmation test. One week after the start of the test, the foodstuff was taken out from each glass container and transferred to a clean cup having a hole with an inner diameter of 3 mm on the top surface. The cup containing the ingredients transferred from the drug-treated area of Examples 1 to 3 and the cup containing the ingredients transferred from the non-treated control area were placed side by side in a container in which the flies were released, and after 24 hours had passed, each cup was invaded. The number of flying flies was counted, and the attraction inhibition rate (%) was determined by the following formula.
Attraction inhibition rate (%) = (Cn-Tn)/Cn x 100
Tn: Number of flies invading the cup into which the ingredients were transferred from the drug-treated area (individuals)
Cn: Number of flies intruding into the cup into which the ingredients were transferred from the non-treated control group (individuals)
Table 5 shows the attraction inhibition rate of fruit flies and flea flies for each food type.

In Example 1, the lowest attraction inhibition rate for Drosophila was 83% when konjac was used as the food material. When any one of apples, dried sardines, and shrimp was used as the food material, the attraction inhibition rate for Drosophila was 100%. In addition, the lowest rate of inhibition of flea fly attraction was 76% when crab miso was used as the food material. When any one of bread, bananas, apples, dried sardines, and shrimp was used as the food material, the attraction inhibition rate for flea flies was 100%. In Example 2, the lowest rate of inhibition of Drosophila attraction was 85% when crab miso was used as the food material. When any one of bread, apples, dried sardines, shrimp, and cheese was used as food materials, the attraction inhibition rate for Drosophila was 100%. In addition, the lowest rate of inhibition of flea fly attraction was 76% when crab miso was used as the food material. When any one of pork, banana, apple, dried sardines, shrimp, and cheese was used as the food material, the attraction inhibition rate for flea flies was 100%. In Example 3, the lowest attraction inhibition rate for Drosophila was 83% when konjac was used as the food material. When any one of bread, bananas, apples, dried sardines, and cheese was used as the food material, the attraction inhibition rate for Drosophila was 100%. In addition, the lowest rate of inhibition of flea fly attraction was 72% when crab miso was used as the food material. When any one of bread, bananas, apples, and dried sardines was used as the food material, the attraction inhibition rate for flea flies was 100%. From the above results, it was confirmed that the products for controlling flying insect pests for garbage containers of Examples 1 to 3 exhibited an excellent inhibitory effect on attracting and inhibiting the attraction of flying insects to any foodstuff.

[Knockdown effect confirmation test]
Five plastic cylinders (inner diameter: 20 cm, height: 43 cm) covered with glass plates were prepared. In the first plastic cylinder, the flying pest control product for garbage containers of Example 1 was attached to the inside of the glass plate, and in the second plastic cylinder, the glass plate of Example 2 was attached to the inside of the glass plate. The flying pest control product is pasted, and in the third plastic cylinder, the flying pest control product for garbage containers of Example 3 is pasted on the inside of the glass plate, and in the fourth plastic cylinder, the inside of the glass plate. The flying pest control product for garbage containers of Example 4 was attached to the fifth plastic cylinder, and the flying pest control product for garbage containers of Comparative Example 1 was attached to the inside of the glass plate of the fifth plastic cylinder. These were stored at room temperature (25°C), and 4 days, 19 days, and 30 days after the start of storage, 30 Drosophila were released into each plastic cylinder, and the number of knockdown flies was counted over time. KT50 values were determined. Table 6 shows the results of the knockdown effect confirmation test in Examples 1 to 4 and Comparative Example 1.

As a result of the knockdown effect confirmation test, the products for controlling flying pests for garbage containers of Examples 1 to 4 did not suppress the flying pests for garbage containers of Comparative Example 1 at any time point of 4 days, 19 days, and 30 days after the start of storage. KT50 values were lower than control products. From the above results, it was confirmed that the products for controlling flying insect pests for garbage containers of Examples exhibit excellent knockdown effects over a long period of time. Among the flying insect control products for garbage containers of Examples 1 to 4, the increase in KT50 value from 4 days to 30 days was 13.1 minutes with the flying insect control product for garbage containers of Example 4. , Compared to this, the flying pest control product for garbage containers of Example 1 took 1.3 minutes, the flying pest control product for garbage containers of Example 2 took 4.6 minutes, and the flying pest control product for garbage containers of Example 3 took 1.3 minutes. The product was 5.3 minutes, and the increase in the KT50 value from the 4th day to the 30th day was suppressed for the flying insect control products for garbage containers of Examples 1 to 3. This is because the area ratio Sa/Sb between the insecticidal component-releasing portion and the antibacterial component-releasing portion was 10.7 in the flying pest control product for trash containers of Example 4, whereas the trash of Examples 1 to 3 This is probably because the insecticidal component-releasing portion of the container-use product for controlling flying insects had a relatively small area ratio Sa/Sb of 6.7, and thus the effect of the insecticidal component was maintained for a long period of time.

[Repellent effect confirmation test]
A glass plate was placed on top of a plastic cylinder (inner diameter: 20 cm, height: 43 cm) to cover it. The flying pest control product for garbage containers of Example 1 was adhered to the inside of this glass plate, and the plastic cylinder was stored at room temperature (25° C.) for 30 days. After 30 days had passed, the plastic cylinder was placed in a position where the glass plate was displaced from the upper part, and a bait for attracting small flies was placed in the cylinder, which was used as a drug-treated area. Furthermore, a plastic cylinder of the same shape was prepared, and a bait for attracting small flies was placed in the cylinder, which was used as an untreated control group. A drug-treated area and an untreated control area were placed side by side in a test room of 6 m ³ , and 100 adult fruit flies and 100 adult flea flies were released into the test room. After 24 hours, the number of insects invading each cylinder was counted, and the repelling rate (%) was determined by the following formula.
Repellency rate (%) = (Ci-Ti)/Ci x 100
Ti: Number of insects (individuals) invading the drug-treated area
Ci: the number of invading insects (individuals) in the untreated control plot

In the same procedure, the repellent rate (%) of the products for controlling flying insects for garbage containers of Examples 2 and 3 and Comparative Example 1 was also determined. Table 7 shows the results of repellent effect confirmation tests in Examples 1 to 3 and Comparative Example 1.

As a result of the repelling effect confirmation test, the flying pest control products for garbage containers of Examples 1 to 3 had a higher repelling rate than the flying pest control product for garbage containers of Comparative Example 1 against both Drosophila and flea flies. . In particular, the flying pest control products for litter containers of Examples 1 and 3 exhibited 100% repellency against Drosophila. From the above, it was confirmed that the products for controlling flying insect pests for garbage containers of Examples 1 to 3 exhibited an excellent repelling effect against fruit flies.

The product for controlling flying insects for garbage containers of the present invention can be suitably used as garbage containers, but can also be used in closed spaces for storing food such as rice bins and vegetable bins.
