Abstract

[PROBLEMS] To provide a trapping device that enables safe use of attractants tending to, when ingested in human, pets, etc., cause poisoning therein, and that reduces maintenance management labor and consumable supplies, and that is free from generation of putrefactive smell of mollusks. [MEANS FOR SOLVING PROBLEMS] There is provided a mollusk trapping device wherein in order to paralyze the sensory organ of mollusks to thereby lower the capability of risk aversion and thus cause them to fail to avert a substance capable of inducing a body fluid secretion reaction, the mollusks are caused to ingest an attractant disposed in the trapping device, or exposed to an aroma of attractant held in aroma retaining part (8), or both. The attractant is also used for paralyzing of the sensory organ. The mollusks having their sensory organs paralyzed would fail to avert a substance capable of inducing a body fluid secretion reaction and would die by dehydration or drowning. Putrefaction of the mollusks can be prevented by using 10 mass% or more supersaturated or granular chlorides as the substance capable of inducing a body fluid secretion reaction. For avoiding contact of human, pets, etc. with the attractant, breathable screen (19) through which only aroma can pass is disposed at an opening of attractant container (5).

Description

Specification

Mollusk trap

Technical field

[0001] The present invention relates to a mollusc trap.

Background art

[0002] Methaldehyde has been used as an attractant to evaporate molluscs by inhaling the fruit-like fragrance of low concentrations of acetoaldehyde, and then intoxicated when ingested. The evasion ability decline was an unknown force. Also, there was no known method to capture by reducing the ability to avoid danger by paralyzing the sensory organs even when no addictive amount of attractant was taken!

[0003] Salt is a substance that causes mollusc secretion in the mollusk, and is known to avoid contact, but has not been used in traps for the purpose of preserving molluscs.

[0004] There has been a trap that attracts ripe fruits and vegetables by floating them in salt water (see Non-Patent Document 1, for example).

There was an attractant that paralyzes and exterminates sensory organs (see, for example, Patent Document 1). There has been a trap that places an attractant on cardboard or the like whose surface is thinly covered with salt to cause dehydration due to salt or to take the attractant and cause poisoning (see, for example, Patent Document 2).

There was a trap where the attractant was placed at the top of the trap and the poison was ingested in the trap. (For example, see Patent Document 3).

There was a trap that caused water to die with a device that attracted and dropped (see, for example, Patent Document 4). Shielded by the cover, there is a trap having a plurality of holes (for example, see Patent Document 5.) ₀

Disclosure of the invention

Problems to be solved by the invention

[0006] Conventionally, mollusc attractants have the danger of causing poisoning by humans, pets, and wildlife, and there has been a risk of releasing molluscs and attractants to the environment. The traps had to be cleaned every few days, and if there was a cleaning leak, a rotting odor was generated, and spiders were attracted and propagated, or poisoning and rot occurred around the trap.

[0007] The present invention provides a trap that safely uses an attractant that causes poisoning when ingested by a person, a pet, or the like, and that does not generate a rotting odor of a captured mollusk with less maintenance and consumables. With the goal.

Means for solving the problem

In order to achieve the above object, the present invention, as a first problem-solving means, reduces the risk avoidance ability by paralyzing the mollusk's sensory organs with an attractant that also functions as a sensory organ paralysis agent, thereby reducing the fluid secretion reaction. Molluscs that cause molluscs to ingest attractants placed in traps, expose the fragrances of attractants that have accumulated in the fragrance reservoir 8, or are used together Provide a trap.

[0009] The second means for solving the problem is to use metaaldehyde, paraaldehyde, or ethanol alone or in combination as an attractant that also serves as a sensory organ paralysis agent.

[0010] The third problem solving means is to use 10% by mass or more of a supersaturated or granular salty soot to preserve a mollusk captured also as a substance that causes a fluid secretion reaction. .

[0011] A fourth problem solving means uses an attractant container 5 provided with a ventilation screen 19 in an opening.

The invention's effect

[0012] According to the first problem solving means, the fragrance of the attractant accumulated in the fragrance reservoir 8 paralyzes the sensory organs of the soft body animals and reduces the danger avoidance ability. In addition, the soft body that took the attractant Animals are paralyzed and their ability to avoid danger is reduced. Because of the reduced risk-avoidance ability, contact with a substance that causes a fluid secretion reaction fails. A salt solution with a concentration of 1% by mass or more, which is about twice the salinity of molluscs, can be used as a substance that causes a fluid secretion reaction. Although stalagmite can also cause fluid secretion, in the case of inverted sarcophagus, which is a chemical substance that is a toxic and difficult-to-decompose chemical detergent, it is contaminated with soil, rivers, etc. It is necessary to consider the dangers.

[0013] Mollusks are paralyzed by sensory organs and exposed to high-concentration fragrances, or are exposed to fragrances for a long time, and cannot move. Conventionally, the low-concentration aroma of the attractant has been used for the attracting action, but in the present invention, the aroma reservoir 8 is provided and the aroma of the attractant is used as a sensory organ paralyzing agent. In addition, when attracting an attractant, if the sensory organ is paralyzed as a sensory organ paralyzing agent, it is not necessary to ingest the lethal dose necessary for toxic death. Even if there is no device that can slip on a powdered attractant placed on a tilted shelf, sink by a mollusk on vegetables floating in the water, or rotate or deform by the weight of the mollusk can do.

[0014] However, when the amount of released fragrance is large or the wind is shielded more than necessary, strong stimulating force also causes a repellent reaction and the mollusk does not enter the trap. There are the following methods to avoid the repelling reaction.

(Ii) Limit the amount of fragrance released.

(Mouth) By paralyzing the sensory organs with a low-concentration fragrance, a wind-proof structure is formed so that it can move for a higher concentration.

(C) Arrange the attractant at a position lower than the inlet 6.

[0015] As with mollusks, the fragrance that attracts flower buds and germinated buds is also attracted to aroma. However, it is a repellent reaction at a lower concentration of fragrance than molluscs. It can also be used as a guide for reducing the amount of fragrance generated by attractants when they are caught. In the case of a low-concentration fragrance, if the attractant is placed at a position lower than the inlet 6, both molluscs and snails may be captured.

[0016] By arranging the attractant in the upper part of the trap, the aroma concentration of the aroma reservoir 8 can be increased because the aroma specific gravity is heavier than air. When the inlet 6 is provided at a position lower than the attractant, the fragrance flows out of the inlet due to air convection and is effective for diffusion of the fragrance. There are fruits. When the attractant is installed at a position lower than the inlet of the fragrance reservoir 8 or the like, the release of fragrance out of the trap due to air convection is reduced, but the trap concentration is lower because the fragrance concentration in the upper trap 1 is lower Molluscs easily enter the upper vessel. In this case, mollusks approach a substance that produces a fluid secretion reaction, increasing the chance of contact with a substance that produces a fluid secretion reaction. However, the attractant may be immersed in a substance that causes a fluid secretion reaction.

[0017] When an attractant is placed in the upper part 1 of the trap and the placed surface is faced down on the ceiling or sideways on the wall, the mollusk killed by poisoning falls and the attractant is less deteriorated. When ingested and hesitated, due to sensory organ paralysis, avoidance of substances that cause fluid secretion reaction fails, leading to death from water or dehydration.

[0018] In order to maintain the attractant fragrance concentration moderately, the following structure is used.

The bottle structure can reduce the ventilation volume by making the inlet part 6 narrower than the diameter of the aroma storage part 8. If the entrance 6 is a single power point, the ventilation effect that occurs in multiple cases can be prevented. The upper part of the fragrance storage part 8 can be made low concentration and the lower part can be made high concentration by partial ventilation by wind and convection by specific gravity of fragrance.

[0019] By providing the windproof passage 10 with the opening at a position lower than the inlet 6 at the inlet 6, the wind can be prevented from being directly blown into the fragrance reservoir 8. Since the fragrance convects by making the opening of the windbreak passage 10 lower than the inlet 6, the mollusk can move to the fragrance reservoir 8.

[0020] The windproof cover 11 can keep the fragrance of the fragrance reservoir 8 by covering the trap so that the wind is not directly applied to the trap. An inlet 13 is provided below the windproof cover 11 to diffuse the fragrance out of the windproof cover 11. The fragrance concentration can be a low concentration in the upper part of the fragrance storage part 8 and a high concentration in the lower part of the fragrance storage part 8. A plurality of inlets 13 may be provided. Alternatively, the attractant loading unit 3 may be disposed above the windproof cover 11 and the aroma storage unit 8 may be disposed below.

[0021] According to the second means for solving the problem, metaaldehyde, noraldehyde, or ethanol can be used alone or in combination as an attractant that also functions as a sensory organ paralysis agent. Metaaldehyde paraaldehyde slowly releases cetaldehyde. Ethanol is absorbed from the sensory organs, breathing apparatus or body surface and decomposed in the body to become cetaldehyde. ethanol Since it is easy to evaporate, it is necessary to devise methods such as evaporating slowly through a permeable membrane. Many aromatic compounds have sensory organ paralysis, but it is desirable not to use those that are inappropriate as agricultural materials due to toxicity and persistent properties.

[0022] According to the third problem-solving means, the captured mollusk is preserved by using 10% by mass or more of supersaturated or granular chloride, which also serves as a substance that causes a fluid secretion reaction. . In the case of 10% by mass or more, there is an effect of suppressing the growth of microorganisms. A salty product with a concentration of 1% by mass or more, which is about twice the salinity of the mollusc, also produces a fluid secretion reaction. Rot odors can evade molluscs and attract and propagate pupae. When using salt water mixed with yeast as an attractant, it was not used at fermented salt concentrations to prevent spoilage. It was necessary to wash every few days due to spoilage in traps that floated lettuce, etc. in lithic acid solution or salt water, or used beer.

[0023] Use a 10% or more by weight or supersaturated saline solution when the amount of trapping is high after the trap is installed. Granular chloride can be used when the amount captured is low. By preserving it, maintenance work such as cleaning the trap can be reduced. However, if scales such as cocoons float on the surface of the salt water, mold may propagate, so it is desirable to wash once a month even when the amount of catch is reduced. When the substance causing the body fluid secretion reaction is an aqueous solution, it is difficult to avoid because the antennae of the mollusk with the body surface covered with mucus suck up and raise the water surface by touching the water surface.

[0024] Salt and bittern can be used for the salty cake. Avoid using salt produced by the sun salt method because it may contain halophilic microorganisms. Chloride of 10% by mass or more can prevent the growth of salt-tolerant microorganisms such as food poisoning bacteria. Suppression of fragrance degradation by microorganisms can also be expected.

[0025] According to the fourth problem solving means, the following effects can be obtained by using the attractant container 5 provided with the ventilation screen 19 in the opening.

(Ii) Prevents contamination of crops, etc., because the attractant does not adhere to fingers during loading and replacement.

(Mouth) To prevent poisoning because pets cannot take the attractant.

(C) Prevent deterioration of attractants due to body fluids of molluscs. (2) Prevent outflow of the attractant into the river by not using the container power.

(E) Since the attractant is not ingested, the loading amount of the attractant can be reduced.

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, embodiments of the present invention will be described.

[0027] Figs. 1 and 2 show that the inlet portion 6 has a bottle structure that is narrower than the diameter of the fragrance storage portion 8, thereby reducing the amount of air blown, and the inlet portion 6 is made into one power point to depend on the wind. This is an embodiment of a catcher having a windproof structure with little ventilation.

[0028] 1 is an upper part of the trap and 2 is a lower part of the trap, and they are connected so that the fragrance does not leak.

[0029] 3 is an attractant loading unit, 5 is an attracting agent container, 18 is an attracting agent, 19 is a ventilation screen, and 4 is an attracting agent loading unit lid. The attractant loading part lid 4 is connected to the upper part 1 of the trap.

[0030] Reference numeral 7 denotes an intrusion prevention screen, which does not block the aeration of the fragrance descending from the attractant loading unit 3.

Let the size of the eye that mollusks cannot pass through.

[0031] Reference numeral 6 denotes an inlet, which prevents rainwater, irrigation to crops and the like from entering the trap. The shape of the inlet 6 can reduce the direct blowing of wind into the trap. Inlet 6 Force S In one case, ventilation can be reduced. If the amount of fragrance released is large, a plurality of inlet portions 6 may be provided.

[0032] Reference numeral 8 denotes an aroma storage unit that stores the aroma that descends from the attractant loading unit 3. In the aroma storage part 8, salty soot is placed. Mollusks are hesitant in the state of danger avoidance due to paralysis of the sensory organs caused by the fragrance stored in the fragrance reservoir 8, and contact with salt and dehydrated or drowned.

[0033] When there is a large amount of capture, add salty soot to keep the concentration of 10% by mass or more.

If the amount captured is reduced, granular salty soot can be used in the aroma reservoir 8.

[0034] In the case where the volume of the fragrance reservoir 8 is 500 ml, when using sodium chloride as chloride, 20 g of sodium chloride is added to 50 ml of water to form supersaturated saline. When the water level reaches 40% of the volume, the concentration of salt and soot drops to 10% by mass, creating a risk of spoilage. The captured mollusks are disposed and washed. With 5g of salt, there is a risk of spoilage when the water level reaches 10% of the volume. If the aqueous solution becomes cloudy or if the captured mollusk has swollen due to water absorption, the mollusk should be disposed of and washed because there is a risk of spoilage. [0035] The aroma storage unit 8 can be taken out from the lower trap 2 and washed. The aroma storage part 8 and the catcher lower part 2 may be integrally formed. If the salt and soot placed in the fragrance reservoir 8 is mixed with the surrounding soil, it may affect the growth of some crops, so it is necessary to dispose of it appropriately.

[0036] Reference numeral 9 denotes a fall prevention plate, which prevents the fall by widening the bottom. If the trap is installed underneath the soil, it will be pulled out and can be installed stably. In this case, the ground clearance at the entrance 6 is lowered, so that the rubber dungeon easily enters the trap.

[0037] Instead of the intrusion prevention screen 7 and the attractant container 5, the attractant may be fixed with glue or the like and placed downward or sideways so that mollusks can ingest it. Mollusks that are ingested and killed by poisoning fall. If sensory organs are paralyzed by ingestion, salty sores can be avoided. In the case of traps that can receive attractants, limited use of a very small amount of attractant is desirable.

[0038] FIGS. 3 and 4 show an embodiment in which a windbreak passage is provided in the inlet portion 6 in the trap of the embodiment shown in FIGS. 1 and 2 in order to reduce diffusion of fragrance in the fragrance reservoir 8 by wind. It is. 10 is a windbreak passage.

FIGS. 5 and 6 show an embodiment in which a windproof cover 11 covering the trap is installed. 11 is the windproof cover. 12 is a bottom cover of the windproof cover. Reference numeral 13 denotes an entrance for a mollusk to enter the windproof cover 11. The bottom cover 12 of the windproof cover 11 and the aroma storage part 8 may be integrally formed.

FIGS. 7 and 8 show an embodiment in which the attractant loading portion 3 is fixed inside the windproof cover 11 and the fragrance storing portion 8 provided with the slit of the inlet portion 6 is disposed below the attractant loading portion 3. However, there is no gap between the wall surface of the attractant loading unit 3 and the upper end of the aroma storage unit 8 so that the mollusk can move to the aroma storage unit 8.

[0041] By forming the attractant loading portion 3 inside the trap, it becomes difficult to be destroyed by a pet or the like. This loading method can also be employed in the embodiment of FIGS.

[0042] As an example of the shape of the windproof cover 11, it is sufficient that there is a space in which a trap can be formed inside, so that an object that decorates the garden can be in any form such as a person, animal, house, vehicle, stump, rock, etc. Can do.

[0043] Figures 9 and 10 are traps that are installed inside a windproof cover made of ceramic or the like. . 14 is a hook. 15 is a holding plate and 16 is a screw. Provide a protrusion to attach the trap inside the windbreak cover and fix it. 17 is a taxiway. This is a passage for mollusks to move to the catcher when the aroma storage part 8 is separated from the ground force by the attachment position of the catcher to the cover made of ceramics. Use a flexible material, and adjust the distance from the ground to the fragrance reservoir 8.

FIG. 11 shows an example in which a throttle for adjusting the amount of released fragrance is attached to the attractant loading unit lid 4 of FIGS. 7 to 10.

21 is an aperture. It is used to adjust the amount of fragrance released in the case of attractant container 5 with a large amount of fragrance released by combining the ventilation part and the shielding part. After loading the attractant container 5, squeeze the throttle 21 for several days so that no repellent reaction occurs.

FIGS. 12 and 13 are explanatory diagrams of the attractant container 5 used for the trap.

[0046] Reference numeral 19 denotes a ventilation screen. Use a board or net with a fine hole and a non-woven fabric.

[0047] Reference numeral 20 denotes an attractant container lid. Remove when loading attractant container 5. Fix non-breathable film, etc. in the opening with adhesive, etc. to prevent chemicals from evaporating during storage.

[0048] 18 is an attractant. An example of a specific method of filling the attractant container 5 with the attractant 18 is as follows:

(Ii) Make a cloth or non-woven bag with rosin as a raw material and enclose the attractant.

(Mouth) The bag of (i) is fixed to the attractant container 5 by heat welding or the like.

(C) A reticulated resin is thermally welded to the opening of the attracting agent container 5 as the ventilation screen 19. (2) Attach the attractant container lid 20 with an adhesive or the like to the opening of the attractant container 5.

As described above, the attractant container 5 that does not directly touch the attractant is configured. Alternatively, the attracting agent container 5 and the attracting agent loading unit lid 4 may be integrally formed and directly loaded with the attracting agent, and the ventilation screen 19 may be provided.

[0049] The attractant 18 is based on metaaldehyde. Moisture absorption, mold generation, yeast, and lactic acid bacteria are easy to ferment. Organic substances expedite the consumption of metaaldehyde, so do not mix. Clays may be mixed for convenience in forming calories. If too much fragrance is released, mollusks are repelled.If processed to release fragrance gently over a long period of time, mixing of a porous material is reduced and fragrance is generated by mixing a thickener such as glycerin. Adjust the amount . In addition, you may mix | blend an emetic etc. for ingestion prevention of a pet etc. However, there shall be no odor that mollusks avoid.

[0050] In the trap shown in Figs. 1 to 10, the attractant loading unit 3 may be provided on the wall surface of the force aroma storage unit 8 shown in the figure attached to the ceiling surface. In this case, the opportunity for mollusks to contact increases because the attractant approaches the substance that causes a fluid secretion reaction. In addition, mollusks can be captured when a commercially available attractant is loaded on the intrusion prevention screen 7 shown in FIGS. 1 and 2 without using the attractant container 5. In addition, when the mollusk is used as a trap that can receive the attractant, it is desirable to keep the attractant loaded in an extremely small amount.

[0051] The material and paint of the trap are those that do not contain or have no effect on formaldehyde that the mollusc repels. Since cetaldehyde is a corrosive gas, avoid using metal materials such as copper.

[0052] Avoid installing traps near ventilation windows or exhaust fans. In windy conditions, the fragrance flows to the lower side, so it is desirable to install the trap on the ground surface.

Example

[0053] Using a laboratory trap simplified in Figs. 1 and 2, the captured mollusk was left untreated for about 1 month. About one month after installation, the aroma reservoir 8 was washed without changing the attractant, and 20 g of granular salt was placed in the same installation location.

[0054] Conditions such as the size of the trap used in the experiment are as follows.

(Ii) The volume of the aroma storage 8 is 500 ml.

(Mouth) Use 10g of salt in 25ml of water.

(C) Attractant containing 3% by mass of methaldehyde 1. Load 5g into the ingress prevention screen 7. (-) 4. Installed one entrance 6 with an opening area of 5 square centimeters.

[0055] The following was observed in this experiment.

(Ii) Observe the first capture 4 days after installation.

(Mouth) The capture of the dandelion is not observed.

(C) About 1 month later, mold was generated on part of the water surface. There is a raw odor but no rot odor. Cockroaches were captured.

(2) Mollusks do not rot and remain in shape. (E) Approximately 1 month after installation, mollusks were observed when granular salt was placed after washing the aroma storage 8.

[0056] The following can be considered in this experiment.

(Ii) Immediately after installation, the amount of fragrance generated is large, and because of the windbreak structure of the trap, it cannot be captured by repelling reaction in the case of high concentration fragrance.

(Mouth) After about 1 week from the start of capture, no new capture will be seen. If the amount of catch is large, it can be inferred that the odor that mollusks avoid is generated even if salty spoilage prevents spoilage.

(C) If left for a long period of time, there may be mold on the surface of the water due to spoilage due to a decrease in salinity due to the amount captured, or scales of straw.

(2) The rot odor was prevented by the antiseptic action of high-concentration chlorides, and the growth of straw was prevented. (E) An effective fragrance was generated after about one month.

[0057] When a trap with an attractant of 0.1 lg and a volume of the scent reservoir 8 of about 100 ml was used, simultaneous capture of mollusks and grasshoppers was observed. It can be inferred that dandelion shows a repellent reaction at a lower concentration than molluscs.
