Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a cockroach catcher that captures cockroaches using electric shock.
[0002]
[Prior art]
Conventionally, as this type of cockroach catcher, a capture device described in JP-B-48-24228 and a capture device and a capture technique described in JP-T-56-500479 have been filed.
[0003]
In the former capturing device, a strip-shaped electrode is attached to the inside of a cylindrical container, and the cockroach attracted to the inside of the container is attracted to the band-shaped electrode by a bait or the like installed inside the container. Upon contact, it falls into the container due to electric shock. This is a device that captures this dropped cockroach.
[0004]
In the latter trap and catching technique, a conductor is arranged near the top of a substantially mountain-shaped container formed for cockroach guidance, and the conductor is provided so as to emit a pulse with a current of 300 to 400 volts. . When the cockroach attracted by an attractant such as a synthetic pheromone agent comes into contact with the conductor, the cockroach is provided so as to fall into the container from a gap formed between the conductors, and the dropped cockroach is arranged inside the container. Captured by a trap.
[0005]
[Problems to be solved by the invention]
The following problems remain in the conventional trap using the electric shock. A first problem is that the conductive effect of a strip electrode or a conductor that gives an electric shock to a cockroach decreases every time a cockroach is captured. That is, the electrodes used in the trap are those in which elongated electrodes are arranged in parallel on the surface of the band-shaped base. When the cockroach comes into contact with the positive electrode and the negative electrode at the same time, the cockroach falls down due to electric shock. However, the cockroach that has received an electric shock releases body fluid due to an electric shock and adheres to the electrode surface or remains between the electrodes. Therefore, the greater the number of cockroaches that have received an electric shock at the electrode, the more the electrode becomes dirty, and if used for about a month, it will be difficult for current to flow from the electrode surface, and if body fluids etc. accumulate between the electrodes, the electrodes will short-circuit. There was also an inconvenience. Therefore, maintenance of the electrode, such as always cleaning the electrode surface, has been a very important task. In addition, there is also an inconvenience that the life of the electrode itself is shortened due to repeated cleaning of the electrode surface.
[0006]
The second problem lies in the timing of supplying the electric charge. It is known that if a current is constantly applied to the electrode, the cockroach will be alert and the capture rate will decrease. Therefore, the latter capturing device and capturing technique raise the capturing effect by setting the energization within 1 second at 10-second intervals in a pulsed manner. However, although this timing is more effective than the state where power is constantly supplied, this timing is not the optimal timing for capturing cockroaches.
[0007]
A third problem is the relationship between the shape of the container and the attractant. The latter traps and capture techniques use synthetic pheromone agents as attractants. This synthetic pheromone agent has been found to have an extremely high attracting effect as compared with other attractants such as baits. However, in the latter catcher and catching technology, a lid is placed over the entire container on which the cockroach travels, and a space for attracting the cockroach is formed in a gap shape preferred by the cockroach, so that the synthetic device mounted inside the container is used. The pheromone agent had a structure that was difficult to spread to the outside of the container from this gap. Therefore, by improving the container shape suitable for the synthetic pheromone agent having an excellent attraction effect, it becomes possible to capture more cockroaches.
[0008]
In view of the above, the present invention has been made to solve the above-described problem.In a trap using an electric shock, it is possible to provide an electrode having excellent durability and to supply electricity at an optimal timing for capturing a cockroach. Another object of the present invention is to provide a cockroach trap that can extend the attracting effect when a synthetic pheromone agent is used as an attractant.
[0009]
[Means for Solving the Problems]
In order to achieve the above object, a first means of the present invention is a cockroach trap using a synthetic pheromone agent as an attractant 3 in which a strip-shaped electrode plate 2 is arranged in a capture container 1 having a mountain-shaped cross section. The strip-shaped electrode plate 2 has an insulating rail 2C disposed between substantially linear electrodes 2B provided on the surface of a strip-shaped base 2A.
[0010]
In the second means, the strip-shaped electrode plate 2 is energized in a pulse shape within 1 second at intervals of 20 seconds to 25 seconds.
[0011]
The third means uses an electrode 2B in the strip-shaped electrode plate 2 in which a surface of a copper foil 2Ba printed on a strip-shaped base 2A is plated with solder 2Bb.
[0012]
The attractant 3 in the fourth means is disposed at the central top of the trapping vessel 1, and the inclination toward the central top of the trapping vessel 1 is set at an inclination angle of 25 ° to 35 ° to solve the problem. Means.
[0013]
According to the present invention, since the insulating rail 2C is disposed between the electrodes 2B of the strip-shaped electrode plate 2, there is no short circuit even if the cockroach body fluid accumulates between the electrodes 2B. Further, the solder plating 2Bb applied to the surface of the copper foil 2Ba can improve the durability of the electrode 2B. The band-shaped electrode plate 2, which is energized in a pulsed manner at intervals of 20 seconds to 25 seconds, captures cockroaches most effectively without giving a caution.
[0014]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. The basic configuration of the support device of the present invention is composed of a capture container 1, a strip-shaped electrode plate 2, and an attractant 3.
[0015]
The capture container 1 is a container having an open top and a mountain-shaped cross section, and has a pair of inclined side plates 1B from the bottom 1A. In the illustrated example, the bottom 1A and the inclined side plate 1B are formed so as to be splittable (see FIG. 2). By attaching the adhesive sheet 1C detachably in advance in the bottom 1A, the captured cockroaches can be disposed of together with the sheet.
[0016]
The strip-shaped electrode plate 2 is disposed inside the open upper part of the capture container 1. In the illustrated example, a capture plate 1C which is inclined from the top of the inclined side plate 1B to the inside of the capture container 1 is provided, and a pair of band-shaped electrode plates 2 are mounted along the longitudinal direction of the vertical side plate 1C. Then, the attractant 3 is placed above the opening between the strip-shaped electrode plates 2. For this reason, in the embodiment, the mounting table 4 is detachably installed above the opening of the capture container 1, and the attractant 3 is mounted on the lower surface of the mounting table 4 (see FIG. 3). By using the mounting table 4 in this way, an electric system component such as a battery 5, a switch 6, or an electronic circuit for supplying electricity to the strip-shaped electrode plate 2 can be mounted on the mounting table 4. The electric system of the illustrated example includes a battery 7 and a switch 6, a lamp 7 for indicating an energized state, and a power connector 8 (see FIG. 6). The power supply connector 8 is connected to the mounting table 4 and the capture container 1 to energize it. When the mounting table 4 is mounted on the capture container 1, it is connected to a power jack 9 protruding from the capture container 1. (See FIG. 2). By providing the power jack 9, the installation position of the mounting table 4 can be fixed at a fixed position, and when the mounting table 4 is not installed, the power can be reliably turned off.
[0017]
The band-shaped electrode plate 2 has a plurality of substantially linear electrodes 2B provided on the surface of an insulating band-shaped base 2A (see FIG. 4). Then, an insulating rail 2C is arranged between the electrodes 2B (see FIG. 5). The insulating rail 2C is provided along the electrode 2B and functions as a weir provided in a gap between the electrodes 2B. That is, even when moisture is accumulated between the electrodes 2B, the insulating rail 2C blocks the short-circuit of the adjacent electrodes 2B. The electrode 2B is obtained by printing a copper foil 2Ba on the surface of the strip-shaped base 2A and further applying a solder plating 2Bb on the surface of the copper foil 2Ba. Thus, by making the electrode 2B have a double structure, the durability of the strip-shaped electrode plate 2 can be increased.
[0018]
When a current is constantly flowing through the strip-shaped electrode plate 2, cockroaches are warned and power consumption is increased. Therefore, according to the present invention, it is set so that the belt-shaped electrode plate 2 is energized at regular intervals. That is, the intervals between the energization of the strip-shaped electrode plate 2 are 20 to 25 seconds, and the energization is performed in a pulse shape within 1 second (see FIG. 7). Experiments by the inventor have shown that if the energization interval is changed to 10 seconds, cockroaches are alerted and the capture rate drops sharply. Also, when the energizing interval is set to 30 seconds, the cockroach approaching the attractant 3 starts moving away from the strip-shaped electrode plate 2 to the periphery, so that the capture rate decreases. Therefore, it was found that the cycle of 20 to 25 seconds in which the cockroach was approaching the strip-shaped electrode plate 2 was the cycle having the highest capture rate. More preferably, the energizing pulse time is set to about 0.4 seconds, and a setting is made so that a current of about 200 V flows at a frequency of about 600 Hz (see FIG. 8). According to such a setting, it can be operated for about six months with four single batteries (6 V).
[0019]
When the cockroach attracted by the attractant 3 climbs the inclined side plate 1B and comes into contact with the strip-shaped electrode plate 2, it receives an electric shock and is captured in the capture container 1. This attracting agent 3 is provided with a synthetic pheromone agent at the upper central portion of the capture container 1. In this case, the inclination angle of the inclined side plate 1B is set to an angle at which the synthetic pheromone agent is more easily diffused and the caution of cockroaches is reduced, that is, an inclination angle of 25 ° to 35 °. By setting this angle, the synthetic pheromone agent installed in the upper center of the capture container 1 diffuses around along the inclined side plate 1B and attracts cockroaches from a wide area. The cockroach that has come near the capture container 1 runs up the inclined side plate 1B without resistance and comes into contact with the strip-shaped electrode plate 2 on the upper portion of the capture container 1.
[0020]
The attractant 3 uses a synthetic pheromone agent as the attractant 3. It is known that the use of a synthetic pheromone agent called periplaneta americana or platera germanica produces an extremely high attracting effect. Since the attractant 3 is placed on the upper part of the strip-shaped electrode plates 2, the cockroach that has climbed the inclined side plate 1 </ b> B tries to further approach the attractant 3 using the strip-shaped electrode plate 2 as a foothold. At this time, when a pulse-like current flows through the strip-shaped electrode plate 2, it can be instantaneously captured in the capture container 1. The cockroach captured by applying the electric shock in this way releases the body fluid, but does not give time for laying eggs, so that it can be reliably exterminated by the adhesive sheet installed in the capturing container 1.
[0021]
【The invention's effect】
The present invention achieves the original object by being configured as described above. That is, since the insulating rails 2C are arranged between the substantially linear electrodes 2B provided on the surface of the strip-shaped base 2A, even if the cockroach body fluid accumulates between the electrodes 2B, the electrodes 2B can be prevented from short-circuiting.
[0022]
In addition, when the strip-shaped electrode plate 2 is energized in a pulse shape within 1 second at intervals of 20 seconds to 25 seconds, the timing becomes optimal for capturing a cockroach.
[0023]
The strip-shaped electrode plate 2 is formed by printing a copper foil 2Ba on a strip-shaped base 2A and forming an electrode 2B on the surface of the copper foil 2Ba on which a solder plating 2Bb is applied. It can withstand maintenance such as cleaning.
[0024]
Further, when a synthetic pheromone agent is used as the attractant 3 and the attractant 3 is disposed at the top of the center of the capture vessel 1, the inclination toward the center of the capture vessel 1 is set at an inclination angle of 25 ° to 35 °. Then, since the attracting range of the attractant 3 can be expanded, cockroaches can be induced from a wide area.
[0025]
As described above, according to the present invention, in a catcher using an electric shock, it is possible to provide an electrode having excellent durability, to supply electricity at an optimal timing for capturing a cockroach, and to attract a synthetic pheromone agent. When used as an agent, various beneficial effects such as the attraction effect can be widened.
