JPH073896Y2 - Gastropod trap - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a gastropod trap for slugs and the like.

<Prior Art> Heretofore, there has been known a container-shaped container (Japanese Patent Laid-Open No. 56-127035) containing a bait which is mainly composed of methaaldehyde.

<Problems to be solved by the present invention> In the conventional pest control method in which the bait is simply drawn into the container,
The bait itself is attractive, but its lethal power is not so great, so many slugs gather around the bait, but sometimes they escape, and the actual effect is that they are not sufficiently effective.

The present invention has been made to eliminate the above-mentioned conventional drawbacks.

<Means for Solving the Problems> The present invention has a portion having at least one surface having a tapered tip shape in at least a part of a container main body, and forms an entry port on the slope of the tapered portion, and the entry port. The gastropod trap is characterized in that the step is floated below the tapered portion at the lower end position of the.

In the present invention, the shape of the main body is arbitrary as long as it has a cone, a pyramid, a truncated cone, a truncated pyramid, or the like in part or in whole, and the material is water resistant to synthetic resin, metal, glass, wood and paper, and pulp. Examples include processed products and synthetic papers alone or in combination. It does not matter whether it is transparent or opaque.

In the present invention, the means for floating the main body may be any fluid, such as water, solution or sol. In addition, an attractant, a surfactant, an inorganic salt or an organic substance capable of imparting a high osmotic pressure, such as sodium chloride or sorbitol, may be added to the liquid substance.

<Operation> Since the present invention uses the closed type container having the tapered tip portion as described above, it is not necessary to provide the center of the step, and it is difficult for rainwater to enter when it rains, and water vaporizes when it is dry. It keeps the water level constant and prevents slugs from catching very efficiently.

<Embodiment> A detailed description will be given below with reference to the drawings of an embodiment of the present invention. First
FIG. 1 is a vertical cross-sectional view showing an embodiment of the present invention, in which a container main body (1) having a triangular pyramid shape is provided with an entrance (2) above the inclined side peripheral surface.
Are provided, the spherical step (3) floats on the liquid (4), and the attractant (5) is applied to the top surface (1a) of the main body.

When using, simply place the container body (1) on a place where slugs are likely to appear and disappear. For slugs that prefer high humidity, dark place, and appropriate temperature, go to the side of body (1) and enter the entrance (2 ) Intrudes into the main body (1) and rides on the spherical step (3) as it is without any caution, and at that moment, the step (3) rotates under the weight of the slug and falls into the water. The viscous substance from the foot glands of the slug is trying to be squeezed, but this viscous substance is diluted with the fluid and immediately sinks away from the step (3).

In this case, since the closed-type container has a tapered tip, it is not necessary to purposely provide a separate center, and it is difficult for rainwater due to rainfall to enter the container, and because the container is dark and moist, slugs easily enter. There is an advantage.

FIG. 2 is a vertical cross-sectional view and a perspective view showing another example of implementation of the present invention, in which the container body (1) has a sideways triangular prism shape, and the front surface (1-1) of the body (1). And back (1-2)
A rectangular entrance (2) is provided on the upper side, and a roll-like step (3) floats in the water in the main body (1).
The case where the attractant (5) impregnated in the tape (5a) is attached to the top surface portion inside the main body (1) is shown. In this case, since the roll-shaped step (3) floats over the width of the long side of the entrance (2), a large number of slugs can be caught at one time.

FIG. 3 is a vertical cross-sectional view showing still another example of implementation of the present invention, in which the container body (1) has a truncated cone shape, and a large number of small diameters of about 0.5 mm are provided at the center of the side peripheral surface. It is substantially the same as that of FIG. 1 except that a fluid volume adjusting hole (6) consisting of a hole is provided. In this case, since the fluid volume adjusting hole (6) is provided, the height of the fluid can be kept constant, and since it is composed of a large number of small holes, a slug can block the adjusting hole (6). Absent.

FIG. 4 is a vertical cross-sectional view showing still another example of implementation of the present invention, in which two roll-like steps (3) are floated in water in the main body (1) having a mountain-shaped cross section. ) On the inner bottom surface, Na
The case where the sheet (7) holding Cl is attached is shown. In this case, since the sheet (6) is attached to the bottom surface of the main body (1), if the fluid is put into the main body (1) when in use, the NaCl retained in the sheet (6) will enter the fluid. Since it is eluted and becomes a high osmotic pressure fluid, there is an advantage that the slugs are immediately separated from the spherical step (3) and sink to the inner bottom surface of the main body (1). Since the main body (1) is mountain-shaped, there are many entrances, and since the spherical step (3) is floating, there is an advantage that many slugs can be captured at the same time.

<Effect of Device> As described above, the device of the present invention has the portion having the tapered tip, so that it is not necessary to provide the center separately, and the slugs can be captured very effectively.
In addition, it is difficult for rainwater to enter when it rains and prevents evaporation of the fluid when it is dry, so that the height of the fluid in the main body can be kept constant.
