Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a gastropod trap for slugs and the like.

[Prior Art] Conventionally, as a gastropod trap of this type, a container-shaped container containing a bait agent containing metaaldehyde as a main component (Japanese Patent Laid-Open No. 56-1
27035) was known.

[Problems to be solved by the invention]

In the trapping method in which the bait agent is simply pulled into the container like the conventional gastropod trap, since the bait agent itself has an attractive force, many slugs gather around the bait, but the lethal force is not so great. In some cases, they have escaped and the actual capture effect has not been obtained.

The present invention has been made in order to eliminate the above-mentioned conventional problems.

[Means for solving problems]

The present invention is a gastropod trap in which a spherical step is floated in a container containing a fluid, and a tread plate having an opening at the center is provided on the upper part of the container body, and further, on the back surface of the tread plate. A pin is provided, and the tip of the pin is in contact with the side of the spherical step. An attractant may be attached to the back surface of the footboard, or the tip of the pin may be spherical.

In the present invention, the tread plate also serves as a lid, and it is preferable that the entrance opening at the center is circular.

In the present invention, the fluid may be water, solution, sol or the like. Further, an attractant, a surfactant, an inorganic salt or an organic substance capable of giving a high osmotic pressure such as sodium chloride or sorbitol may be added to the fluid.

[Action]

The present invention has the structure as described above, and the position of the spherical step can be held constant by the pin. As soon as the gastropod attracted by the attractant rises to the upper part of the spherical step, the spherical step rotates and loses balance and sinks in the fluid, so large and small gastropods can be surely killed. Further, if the tip of the pin is spherical, the spherical step can be rotated more smoothly.

〔Example〕

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a vertical sectional view showing an embodiment of the present invention.
(1) is a container main body, the upper surface of the container main body (1) is opened, and a tread (2) is attached to the fitting part (2
The fitting plate is fitted in a), and the entrance port (3) is opened at the center of the footboard (2). An attractant (4) is attached to the back surface of the footboard (2). A fluid (5) is filled inside the container body (1), and a spherical step (6) floats in the fluid (5), and the upper part of the spherical step (6) having a diameter larger than the diameter of the entrance (3). The spherical step (6) and / or the fluid (5) so that is below the entry port (3).
The specific gravity or the volume of the fluid (5) in the container is adjusted. When the amount of the fluid (5) increases, the upper part of the spherical step (6) may protrude above the entrance (3), but the diameter of the spherical step (6) is larger than the diameter of the entrance (3). Since it is large, the spherical step (6) does not jump out of the entrance (3) and fall.

A pin (9) having a spherical tip is provided on the back surface of the step plate (2) of the container body (1) with the spherical portion of the pin (9) facing downward. The tip of the pin (9) contacts the side of the spherical step (6). The pin (9) having a spherical tip makes the spherical step (6) rotate more smoothly.

Further, the roof (10) is provided so as to be slidable in the vertical direction with the body portion of the container body (1) as a support portion. This roof (1
0) has an advantage that it can prevent rain from entering when it is installed outdoors, and can function as a lid of the container body (1) when not in use.

In use, the gastropod trap of the present invention configured as described above only requires that the container body (1) be installed at a location where gastropods such as slugs pass. The gastropod climbs up the container body (1) and reaches the footboard (2), is attracted by the attractant (4), and further advances to the upper part of the spherical footstep (6). Rotates. Therefore, the gastropod loses its balance and sinks in the fluid (5), and since the mucus produced from the pedicle is diluted in the fluid (5), the gastropod cannot support its own weight and the container body (1) remains as it is. As it sinks to the bottom, the gastropod is killed. In addition, since the upper part of the spherical step (6) projects above the fluid (5) and is always located at the center of the entrance (3) by the pin (9), the gastropods are placed on the spherical step (6). You can go up from any direction without hesitation.

Although not shown, if a regulation hole provided with a cover for preventing gastropods from entering is provided on the side surface of the container body (1), even if rainwater enters the container body (1), the fluid (5) will not flow. The capacity can always be kept constant. In addition, the intrusion prevention cover prevents gastropods from clogging the adjustment hole.

FIG. 2 is a vertical cross-sectional view showing another embodiment of the present invention, in which the container body (1) is transparent and the step board (2) has an entrance (3).
Substantially the same as that of FIG. 1 except that two containers are provided and a mark (12) for confirming the height of the fluid (5) in the container is provided on the container body (1). Is.

In this case, since two entrances (3) are provided, there is an advantage that many gastropods can be killed at one time. Further, since the mark for confirming the capacity of the fluid (5) is provided, there is an advantage that there is no fear of excessively filling the fluid (5).

[Effect of device]

INDUSTRIAL APPLICABILITY The present invention has the configuration as described above, and therefore, it is possible to surely kill gastropods such as slugs, so that there is no decrease in the trapping effect due to escape from the trap and a sufficient trapping effect is obtained. be able to.
