DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a catcher capable of efficiently catching (controlling) a domestic fowl, which is most disliked by cattle, such as a cow leukemia, at low cost.

[0002]

2. Description of the Prior Art Flying squirrels are blood-sucking insects found in grasslands and forests in the summer and are the most harmful pests of livestock, especially cattle.
Abu, in particular, mediates bovine leukemia, and therefore its control is strongly required. As a method for controlling flies, spraying of insecticides and trapping with insect nets have been performed for a long time, but flies have a strong flight power, a wide habitat range, and a short blood-feeding time Therefore, effective control could not be performed by this method. In addition, the control method by dust bag is that the drug adheres heavily to the back of the cow, but there is little adhesion to the abdomen of the core, so it is a type that parasitizes the back like the sand flies and a long time like the mites. It is effective for the species that do, but it was mostly useless for the flies that are mainly parasitic on the abdomen and have a short attachment time. Furthermore, a method of attaching a powerful insecticide to the cow's body to kill the fly was also tried, but the effect of being washed away by rain etc. immediately disappeared, and although the fly was killed, the cow sucked blood. If that is the case, it will not be a control, so at present the control of insects with insecticides is rarely done.

Therefore, in recent years, as one of the methods for attracting and capturing the flies, a trap method utilizing the property of the flies attracted by the carbon dioxide gas contained in the exhaled breath of the animal has been developed and spread in the field. (Japanese Patent Publication No. 55-40212). The instrument shown in FIG. 4 is a perspective view showing a mode of an apparatus used for this trap method. In this device, carbon dioxide gas filled in the gas cylinder 5 is used as an attractant, and the carbon dioxide gas is discharged to the upper capture chamber 10 to collect the fly trapping chamber 10.
It is diffused to the outside through the entrance 9 to the upper part of the quadrangular pyramid-shaped umbrella plate 11, which is the entrance to The fly is attracted to this carbon dioxide gas, and enters the upper capture chamber 10 made of a transparent acrylic plate through the entry hole at the bottom bottom of the umbrella plate 11, but cannot escape from the capture chamber 10 and is heated by solar heat. Rises,
It is said that it is dehydrated by heat.

However, in the trap by the trap method, there are many flying flies that do not enter the trap chamber and stop around the trap, and fly away, so that only part of the attracted flies can be captured. There are drawbacks. Moreover, the trap by the trap method is not so inexpensive. Furthermore, although the fly that has entered the capture chamber has a return so that it will not easily escape, there is a problem that some of the fly that enters the capture chamber will escape.

[0005]

DISCLOSURE OF THE INVENTION The present inventor has conducted extensive studies in order to solve the above-mentioned conventional problems. In the process, the present inventor noticed that the attracted fly had the property of piercing a needle-shaped mouth device and licking the mouth even if the stopping position was not the skin of a living organism, and utilized this. hand,
Unlike the conventional method of confining it in the capture chamber, the wooden board coated with poison bait is used to kill the fly, thus successfully solving the above-mentioned conventional problem. For Abu, the continuation of blood-sucking behavior depends on whether a needle-shaped mouth device can be easily inserted, and if it can be inserted, it has the habit of licking with a sponge-like mouth like a fly, so it can be used as a wooden board . It was found that the fly can be effectively controlled by using the attracting plate combined with the poison bait.

[0006] That is, an object of the present invention is to solve the above-mentioned conventional problems, and to provide a trap which can efficiently and inexpensively catch a horsefly that cattle dislike, such as transmitting bovine leukemia. Is.

[0007]

[Means for Solving the Problems] That is, the present invention is directed to a poison bait.
A large number of attracting plates made of wood that adheres or penetrates
When combined with a square shape and having a roof structure
Both provide a fly scavenger having a carbon dioxide gas supply means .

Hereinafter, the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view showing one embodiment of the fly catcher of the present invention. FIG. 2 is a sectional view of the attracting plate in the fly catcher of the present invention.

The fly catcher of the present invention attaches or soaks poison bait.
The attracting plate A made of the transparent wooden board 1 is formed into a polygonal shape.
It has a structure with a combination and a roof . Attraction board A
Is not particularly limited as long as it is made of a wood plate that allows the fly to take a blood-sucking action and lasts, but it is preferable to select a plate whose surface condition and hardness are as close as possible to the cow body. As such a wooden board, it is preferable to use a board made of a plywood board, etc., in consideration of the easiness of piercing the flies and the cost.

The poison bait 2 is a combination of literally a poisonous food and a bait food for the fly, for example, a pesticide to which sugar water is added. Using only a poison like an insecticide makes it difficult for the horsefly to take a blood-sucking action, and it is difficult to continue the blood-sucking action. As the insecticide, organophosphorus insecticide, carbamate insecticide,
Although there are chlorine-based insecticides and the like, organophosphorus insecticides are particularly preferable because they have a weak irritating odor and have a high rate of transfer of flies to blood-sucking behavior. According to the organophosphorus insecticide (commercial name: Alphacron, manufactured by Mitsubishi Kasei) used in Examples described later, if the blood-sucking behavior continues for 10 seconds, the fly will convulsively die. It is necessary for Abu to swallow a lethal dose of insecticide in a short time. For the purpose of maintaining the insecticidal effect of the insecticide and enhancing the spreading effect on the attracting plate A, an appropriate additive can be selected as necessary.

The larva catcher of the present invention uses such a poison bait 2
Attracting plate A consisting of a wooden board 1 to which is adhered or permeated
Has a structure in which a roof is provided by combining
It is those that. Adhesion or penetration of the poison bait 2 into the wood board 1
For example, by adding sugar to an insecticide and dissolving it in water, applying it to a wooden board 1 with a brush or the like, or adding sugar to the insecticide and soaking the wooden board 1 in a solution dissolved in water. You can go by. This is the fly catcher of the present invention.
It consists of a wooden board 1 to which eel bait 2 is attached or permeated.
4 attracting plates A combined in a cross shape as shown
It is a combination of polygonal shapes. Further, the attracting plate A may be reinforced by a metal frame material or the like (not shown). Furthermore, the attracting plate A may be attached to a building, a vehicle, or the like, if necessary. Further
In addition, the fly catcher of the present invention, for the purpose of rain protection,
A roof 3 is provided. The shape of the roof 3 is not particularly limited
As the attracting plate A, a set of four in a cross shape as shown
If you use a combination, it looks like a square pyramid,
If you use an umbrella-shaped one, it will improve the efficiency of rain protection and carbon dioxide gas.
It is preferable because a high diffusion effect can be obtained. Also, the material of the roof 3
The quality is not particularly limited, but usually a transparent acrylic plate
Which one should be used?

The fly scavenger of the present invention is further provided with carbon dioxide gas.
It has a feeding means. The carbon dioxide is used as an attractant to attract the flies. The carbon dioxide gas supply means usually comprises a gas cylinder 5 and a rubber hose 6. As such a carbon dioxide gas supply means, the same one as heretofore known can be used.

The fly catcher of the present invention has the structure as described above. Such a fly trap of the present invention,
The attractant bait 2 is attached to or permeates the wood board 1 to manufacture the attracting board A, which is combined in a polygonal shape, and further combined with the carbon dioxide gas supply means and the roof 3. The rubber hose 6 of the carbon dioxide gas supply means is usually inserted from the upper part of the roof 3 toward the inside.

Regarding the usage of the fly catcher of the present invention,
An example of one embodiment of the fly catcher of the present invention shown in FIG. 1 will be described. First, carbon dioxide gas is discharged from the gas cylinder 5 through the rubber hose 6 to the upper part inside the roof 3. FIG. 3 is an explanatory view mainly showing the structure of the head of the fly. The fly attracted by the carbon dioxide gas stops at the attracting plate A and pierces the attracting plate A with the needle-shaped mouth device 7. Since the attracting plate A is made of the wooden plate 1, the attracting plate A is easily stabbed, and the fly is licked by the sponge-like lower lip 8 which is behind the needle-shaped mouth device 7. As described above, since the bait 2 has the bait 2 attached or permeated to the attracting plate A , the fly will swallow it and die.

[0015]

EXAMPLES Next, examples of the present invention will be shown, but the present invention is not limited thereto. Examples and Comparative Examples In the Niikappu ranch of the Livestock Improvement Center of the Ministry of Agriculture, Forestry and Fisheries,
FIG. 2 shows a fourth embodiment of the fly catcher according to the present invention;
As shown in the figure, the trap by the conventional trap method (Japanese Patent Publication Sho 5)
No. 5-40212) (comparative example) was used to investigate the number of catches by type of fly that was caught over 14 days in good weather conditions. The results are shown in Table 1. As a fly catcher (embodiment) of the present invention, as shown in FIGS. 1 and 2, a rain shield acrylic plate (roof 3) is attached to a pyramid type attracting plate A made of a plywood plate, and the attracting plate A is used. Was coated with poison bait. As poison bait, an organic phosphorus insecticide (market name: Alphacron, manufactured by Mitsubishi Kasei) per 1 square meter of attracting plate
To 35 g, 46 g of upper sucrose was added, dissolved in 60 ml of water, and applied with a brush. The total area of the attracting plate was 6 square meters. In addition, carbon dioxide is 1 in both traps.
An injection needle was pierced at the tip of the rubber hose 6 so that it could be discharged at a rate of 1500 to 2000 ml per minute, and the atmospheric pressure was adjusted to 1.5 atmospheric pressure. Furthermore, in order to make the conditions the same as much as possible,
The frontage of both traps was the same 120 cm. Both traps were installed 10 m apart so that the same amount of carbon dioxide gas could flow from the bomb through the branch pipe to both traps.
The gas release time was set from 8:30 to 16:00, and the captured fly was collected immediately after the gas release was stopped. Abu was classified based on "Primary Color Insect Encyclopedia" (Hokurikukan) and "Abu Classification, Ecology and Countermeasures" (Hayafumi Hayakawa, Pharmacodynamics Research, Nos. 23-39).

[0016]

[Table 1]

According to the results shown in Table 1, the ab trap of the present invention (embodiment) has about 2.76 times as many traps of the ab as compared to the conventional trap method (comparative example). You can see that there are many. Further, according to the fly scavenger of the present invention (Example), when the blood-sucking behavior continued for about 10 seconds, the slap caused a convulsion in about 20 seconds and fell, and then died within several seconds. In addition,
The capture ratio by the fly trap of the present invention (Example) is almost in accordance with the number of inhabitants of the flies at the installation site (the number of white-fly flies is overwhelmingly large, followed by sesame flies, holbert flies, bull flies, etc.). it is conceivable that. In addition,
Regarding the large-sized species Akaushiabu, the comparative example was able to capture 5 times more than the Example, but this is because the Akaushiabu prefers to parasitize its back, so that the structure shown in Figs. It is considered that the trap by the conventional trap method (comparative example) having a resting table shaped like the back of a cow (comparative example) is more prone to parasitism than the fly trap of the present invention (example). It would be better to re-examine

[0018] As for the fly, since it is attracted by carbon dioxide gas contained in the exhaled breath of the animal and the parasite partner is identified by the visual sense and the sense of smell in the vicinity, blood-sucking behavior is considered to be applied to non-animals such as plywood. Has been thought not to. However, in the present test, it was confirmed that the fly, which was attracted to carbon dioxide, reflexively immediately moved to the blood-sucking behavior even when the place where it adhered was other than the skin of the animal.

[0019]

INDUSTRIAL APPLICABILITY The fly catcher of the present invention has a high efficiency of catching (controlling) the fly, and in the conventional method, it also prevents the fly from stopping outside the catcher and not entering the catcher. You can That is, according to the fly catcher of the present invention, since the flying fly can be misidentified as a cow and poisoned when it takes a blood-sucking action, most of the attached fly can be killed. Moreover, since the fly catcher of the present invention has a simple structure, it is easy to install and carry and assemble. Next, according to the fly catcher of the present invention, the cost of controlling the fly can be reduced. That is, since the fly catcher of the present invention has a simple structure, the manufacturing cost is low,
The cost of pest control will be lower. Furthermore, according to the fly catcher of the present invention, the number of fly can be reduced. That is, according to the larva trap of the present invention, it is possible to capture the larva that has been missed so far, the number of resident larvae decreases, and the number of escaping and breeding also decreases. It can significantly reduce the number of inhabitants.
Therefore, according to the present invention, it is possible to effectively control flies and effectively prevent the spread of bovine leukemia. The present invention uses the same insecticide as compared to a method for killing all living organisms such as aerial spraying of the insecticide, and use of the same insecticide directly to livestock where there is a concern about residues. However, it is environmentally friendly and is expected to be widely used.
