Description

The present invention relates to a container for fishing bait and larvae of moths used for research.

When fishing in mountain streams such as char, yamame trout, trout, haya, and amago, insect larvae such as grape worms (honey honey moths) are often used as live bait for fishing. The grape larvae are accommodated and carried in the case in a live state. Conventionally, a cardboard-shaped paper protective body having a large number of holes is rolled up and accommodated in the case, and the grapes are accommodated in the holes. Insect larvae were made and kept alive in this (Patent Document 1).

When fishing in a mountain stream, the cardboard-shaped paper protective body rolled out from the case is taken out, the outer paper forming the hole is broken by hand, and the larvae are taken out one by one and attached to the tip of the needle. However, it is difficult to take out a protective body made of strong paper without damaging the larvae, and the larvae may be crushed or broken. Also, there are larvae that enter the hole of the cardboard-shaped paper protective body and make a nest, and those that do not enter and make a nest outside, and the opening part of the hole that does not contain the larva is covered with cocoons However, it was not possible to accurately determine how many larvae were in the corrugated cardboard protective body.

For this reason, there has been proposed a larvae storage container that uses a cylindrical plant “Yoshi” and is cut into a certain length while leaving a node in the middle (Patent Document 2). This is a storage of two vines at the middle node, and when using, you can easily remove the worms by splitting “good” with the toes, and easily the remaining number in the case There is an advantage that can be confirmed. However, since it is a natural product to use “good” of plants, it takes time and effort to harvest and cut, and the inner diameter and thickness are not constant, so the work of selecting the optimal “good” is troublesome. There was a problem that could not be put into practical use.

Also, it is described that instead of the plant “Yoshi”, a cylinder formed of paper or synthetic resin is used, but when the larva is taken out from the inside by breaking the cylinder formed of paper or synthetic resin, There was a problem of crushing the larvae because it was difficult to tear.

The container for moth larvae according to claim 4 of the present invention is characterized in that, in claim 1, caps are attached to both ends of a cylindrical body in which larvae that have formed moths are stored.

According to the container for moth larvae according to claim 1 of the present invention, since slits are formed in the entire circumference of the cylindrical body with perforations or intervals, when taking out the larvae, When one hand grasps one of the storage containers and the other hand grasps the other side of the storage container and folds it, it breaks at an intermediate perforation or slit, and half of the larvae body is exposed. By pulling out the exposed part of the larvae with a finger, the larvae can be taken out easily without being crushed. In addition, the number of larvae in each container is easy to check.

According to the second aspect of the container for moth larvae, the one in which the cylindrical body is made of paper has few environmental problems even if it is discarded as it is after the larvae are taken out. . A synthetic resin formed in a straw shape is easy to manufacture.

According to the container for moth larvae according to claim 3, when grape worms are used as moth larvae for making moths, breeding is easy and effective as live bait for mountain stream fishing.

According to the moth larva storage container of claim 4, since the caps are attached to both ends of the cylindrical body containing the larvae that have produced cocoons inside, the cocoon larvae can be Can be prevented from going outside, especially when used in a laboratory.

Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. FIG. 1 shows a production process of the storage container 1. As shown in FIG. 1A, for example, cardboard paper is cut into a rectangular shape having a length of about 1.5 to 2 cm and a width of about 4 cm. A perforation 3 is formed in the middle of the rectangular cardboard 2 in the lateral direction. Next, the cardboard 2 is wound about twice to form a cylinder, and the ends are glued to form a cylindrical body 4 having both ends opened as shown in FIG.

Next, as shown in FIG. 1C, a larva 5 of, for example, a worm (Honey honey moth) is placed in the cylindrical body 4. In this case, the insertion means puts the cylindrical body 4 and the larvae 5 in the case so that the larvae themselves enter the cylindrical body 4 from themselves. In this way, when the cylindrical body 4 containing the larvae 5 is put in the refrigerator and the temperature is lowered, the larvae 5 spit out the thread and form a cocoon 6 in a few hours, as shown in FIG. 1 (D) and FIG. 2 (A). In this way, the opening of the cylindrical body 4 is closed to form the storage container 1.

Thereafter, a predetermined number of the storage containers 1 in which the baskets 6 are made are placed in a case 8 and stored in a refrigerator as shown in FIG. The case 8 is composed of a case body 9 and a lid portion 10 that is openably and closably connected.
