Description

  The present invention relates to a collection device used for collecting fireflies and laying eggs, and a method for taking out eggs and larvae.

  When collecting fireflies, as shown in Japanese Utility Model Publication No. 7-7420 (Patent Document 1), the fireflies can be captured with an insect trapping net and stored in a plastic insect cage to capture a certain number of insects. It was common to grow with this insect cage until it was transferred to an empty aquarium and lay eggs on a spawning bed placed on the bottom of the aquarium.

Japanese Utility Model Publication No. 7-7420

  However, depending on the place where the plastic insect worms are placed, the humidity of the internal space becomes high and the steaming state is high, and it is stressed by growing a large number of captured fireflies in a narrow space for several hours to several days, resulting in a low egg-laying rate. In many cases, he often died. On the other hand, even if the aquarium is placed in a natural environment aiming at the same environment where fireflies naturally inhabit, problems such as adults being preyed on by moths have been pointed out.

  This invention is made | formed in view of such a point, and makes it a technical subject to provide the technique which can raise the egg-laying rate of a firefly.

  The present invention employs the following means in order to solve the above problems.

  Claim 1 of the present invention is placed on the bottom surface of the internal space of the collection box composed of a net surface that can be visually observed and capable of circulating natural wind to accommodate the captured firefly adults, and the upper surface is open. And a spawning bed comprising a container filled with a liquid and a net that is stretched between the container wall parts so as to be partially immersed in the liquid and on which dry moss is placed. This is a firefly collecting and egg-laying device.

  According to a second aspect of the present invention, the captured firefly is housed in a collection box composed of a mesh surface that can be visually observed and distributed in a natural wind, and is placed on the bottom surface of the internal space of the collection box, In a container filled with a liquid in an open state, it is arranged between the container walls in a state where a part of the liquid is immersed in the liquid, and fireflies on a spawning bed consisting of a net on which dry moss is placed on the top. This is a method for collecting, laying eggs, and removing larvae, which is obtained by immersing the firefly larvae that have hatched in the liquid in the container and washing them out after laying eggs.

  According to a third aspect of the present invention, a container filled with a liquid in a state where the upper surface is opened, and a heat-treated dry moss are placed on the container, and a part of the dry moss is immersed in the liquid. A firefly laying apparatus characterized by a spawning bed comprising a net stretched between the container walls.

According to the present invention, the adult box is grown in the collection box itself for storing the captured fireflies, and the egg laying in the egg laying apparatus arranged in the inside is made possible. It can be passed in the same environment that ensures the distribution of natural wind, and the spawning rate can be increased without giving stress to the captured fireflies.

  In addition, the dried moss that has been heat-treated as the egg-laying bed of the egg-laying apparatus is soaked in a part of the liquid so that egg-laying can be promoted while preventing the propagation of various bacteria.

  The present invention will be described with reference to the drawings.

  FIG. 1 shows a collection box, and FIG. 2 shows a spawning bed.

  The collection box 1 has a frame 2 made of wood, metal or synthetic resin, and a net member 3 made of metal or synthetic resin is stretched on the four side surfaces and the upper surface of the frame 2. The front part 4 of the frame body 2 can be opened and closed like a door, and it is possible to receive or capture adult firefly insects captured through this part. In addition, the net surface may be all six surfaces of the entire side surface and the upper and lower surfaces. By using the entire 6 surfaces as a mesh surface, ventilation is further improved and the same temperature and humidity environment as the outside environment can be maintained. The advantage of using a lower surface as a net surface is that drainage is good even when water leaks from a spawning bed, which will be described later, and generation of mold and the like can be suppressed.

  This collection box 1 contains perch plants in which the firefly can stay. This perch plant is not shown in the figure, but the middle part of the stem with leaves of relatively long leaves, such as Japanese knotweed and mugwort, is gathered with a rubber band and the tip is rounded with moisture for supplying water. Inserted into tissue paper. When such a perch plant is prepared, it must be prepared while the surrounding environment is bright, and care must be taken so that fire enemies such as firewood, moths and ants do not enter the collection box.

  The spawning bed 11 is placed on the bottom surface of the collection box 1, and a liquid (water 13) is filled in a synthetic resin or glass container 12 whose top surface is open, and the top surface further includes a saran net 14. Is stretched. The saran net 14 has a center section processed into a concave shape, and the dried moss 15 is placed on the upper part of the saran net processed into the recess. Here, the container can be formed of a plastic container, and the planar shape thereof may be either a circle or a rectangle. In the case of a quadrangle, the length of the long side and the short side is preferably about 40 cm × 25 cm. The egg-laying bed 11 is placed on a part of the bottom surface in the collection box 1. One egg-laying bed 11 is standard for one collection box 11, but may be two or more.

  It is conceivable to use a gauze or sponge soaked in water as an alternative to the saran net 14, but the gauze soaked in water is difficult to handle and prone to mold, and the sponge dries quickly and If larvae get inside the sponge, it is not suitable because it is difficult to collect. Moreover, if it is a net-like thing, it can be used as a substitute for a saran net.

  As the dry moss 15 placed on the saran net 14, it is preferable to use dry moss. In this regard, general raw moss has the advantage that it is easier to obtain, but there is a possibility that fungi are breeding and it is easy for mold to grow, so it should be noted.

Mineral water is preferable as the water 13 filling the container. Originally, firefly habitat water is the most suitable, but it is difficult to keep it in place, and tap water is not suitable because it requires work such as removing chalk.

  The dried water moss 15 is obtained by heat-treating the water moss and has high water retention characteristics, and is generally used for growing plants such as orchids. Since it is sterilized by heat treatment, it is possible to suppress the propagation of germs even if water is given again.

  The amount of the dried moss 15 is adjusted so that ¼ to ３ is immersed in the water 13. If all of the dry moss 15 is immersed, it will be in a water-immersed state, which is unsuitable as a spawning environment. Even if it is 1/2, there is too much water content and it is unsuitable as a spawning environment. It is considered that it is preferable as a spawning environment to immerse about 1/4 to 1/3 and to absorb water by natural capillary phenomenon. When the amount of dry moss 15 is small, the amount of dents in the recess of the saran net 14 may be adjusted manually or with a tool. Further, the saran net 14 may be only a recessed portion, and the periphery of the recessed portion may be locked to the edge of the container 12 with a wire or the like.

  Eggs laid on the dry moss 15 begin to hatch about 20 days in the case of Heike fireflies and about 25 days in the case of Genji fireflies. The hatched larva falls into the water 13 from the periphery of the recess and lives underwater.

  The saran net 14 is removed from the container 12 every day or every few days, and the larvae that have fallen into the water are transferred to a larva breeder (not shown). Since some larvae stay in the dry moss 15 without falling into the water even after hatching, the saran net 14 with the dry moss 15 still placed on the water 13 in the container 12 is washed out. Thus, it is desirable to reliably recover hatched larvae.

  According to the experiment using the collection / spawning apparatus (spawning bed 11) of the present embodiment, Heike firefly adults (30) were collected in early July, and dried moss 15 on the saran net 14 as described above. As a result of egg laying, hatching began in late July and most of the eggs hatched in about one week. Eventually, about 900 larvae of Heike fireflies were obtained.

On the other hand, according to May 12, 1983, published by Hirakawa Kogyo Co., Ltd. and published by Ichiro Nanki, “Reprinted Firefly Research”, page 12 There is a description that the larva of the individual was obtained.

  From this, it is understood that very high egg-laying efficiency can be realized in this embodiment.

  As mentioned above, although this invention was demonstrated based on embodiment, this invention is not limited to the above embodiment.

  For example, the collection box has been described as having a rectangular parallelepiped shape with six mesh surfaces, but is not limited to this and has any housing shape such as a cylindrical shape, a polygonal column shape, a side surface, or a front trapezoid shape. It may be.

  The present invention can be applied from the collection of fireflies to egg laying.
