  Next, with reference to FIG. 15 in addition to FIGS. 1 to 14, a method for raising pupae according to an embodiment of the present invention will be described. Here, FIG. 15 is a diagram showing a method for raising pupae according to an embodiment of the present invention.

  First, a 1-year-old vinyl bag 13 laid on a 1-3-year-old net 12 laid in a 1-3-year-old breeding container 11 with the 1-year-old straw and feed hatched from eggs. House in. The inside of the 1st to 3rd year old vinyl bag 13 is ventilated through a small hole as shown by an arrow in FIG. 1 so that it is maintained in a moderately humid environment (for example, a relative humidity of 85% or more). Since it becomes moisturized, it grows by eating its feed. In this case, when water repellent processing is applied to the inner surface of the breeding container 11 for 1 to 3 years of age, there is no possibility that the breeding container 11 for 1 to 3 years of age absorbs moisture generated from the feed and loses its shape. .

  Next, the 1st-aged straw and feed are placed on the 1st-3rd-year net 12 via the doorway 16 opened by operating the chuck 17 of the 1st-3rd-year vinyl bag 13. The breeding container 11 is taken out from the vinyl bag 13 for the first to third ages, placed in an indoor environment adjusted to a temperature of about 25 ° C. and a relative humidity of about 50%, and the feed is dried to feed the feed to the fast growing straw. Align growth by making people unable to eat. After that, the first-year moth undergoes the first molting and becomes a second-year moth.

  In addition, the 2nd and 3rd-year pupae were reared in the same manner as the 1st-year pupae as described above, so that the 2nd and 3rd-year pupae were peeled off at the second and third times respectively. To grow into 3 and 4 year old pupae.

  Next, in the breeding container 21 for 4 to 5 years old, the paper 22 and the 4 to 5 years old net 23 are laid in order on the partition plate 28 and the side bent pieces 32, and this 4 to 5 years old net is placed. 23, the 4th-year old straw and feed grown as described above are placed. And the opening of the upper surface of the breeding container 21 for 4-5 years old is covered with the vinyl sheet 24 for 4-5 years old, and the four corners of the vinyl sheet 24 for 4-5 years old are fixed to the latching part 36 with a rubber band. As shown by arrows in FIG. 6, the 4-5 year-old breeding cage 20 is ventilated through a ventilation port 31, a through-hole 33, a small hole in paper 22, and a 4-5 year-old net 23. Since the feed is kept in a moderately humid environment (for example, a relative humidity of 85% or more) and the feed is moisturized, the straw grows by eating the feed.

  During this time, the paper 22 and the 4-5 year-old net 23 are supported by the partition plate 28 and the side bent pieces 32 and fixed at the four corners by the corner bent pieces 35, so that they shift during the breeding of the pupae, There is no bending. Moreover, since the vinyl sheet 24 for 4-5 years old is being fixed to the latching | locking part 36 by the rubber band in the four corners, it does not remove | deviate or bend | curve during breeding of a pupa. Furthermore, by placing the paper 22 below the 4-5 year old net 23, it is possible to prevent the wrinkles that have passed through the 4-5 year old net 23 from falling to the bottom surface 29 of the tray 25.

  Next, the 4 to 5 year old vinyl sheet 24 is removed, and the 4 to 5 year old breeding container 21 on which the 4th to 5th year old net and the feed are placed on the 4 to 5 year old net 23 is placed at a temperature of about 25 ° C. It is placed in an indoor environment adjusted to a relative humidity of 50%, and the feed is dried, so that the growth of the straw is aligned. Thereafter, the 4th-year-old moths undergo the fourth molting and become 5th-year-old moths.

  Also, 5 year old pupae are reared in the same manner as the above 4 year old pupae during the first half. Since feces from the 4th to the 5th ages fall from the 4th to 5th age nets 23 and accumulate on the paper 22, the feces are cleaned by removing the paper 22 after the 5th age. To do.

  On the other hand, when the pupae grow up to the second half of the fifth year of age, the pupae grow larger and there is no risk of the pupae falling from the net 5 for the fourth to fifth ages. . In this case, since the feces of the salmon fall on the paper 22, the feces are cleaned by discarding the feces deposited on the paper 22. In addition, since there is no molting at the age of 5 and it is not necessary to adjust the growth rate of the straw, the feed is always kept moist in a humid environment.

  The cocoons that have become mature as described above are transferred to the bottom surface 42 of the upper culm breeding container 41 in a state of being placed on the 4-5 year-old net 23. Thereafter, four ridges 44 are juxtaposed on the bottom surface 42 via the upper heel spacer 43, and the opening on the upper surface of the upper ridge breeding container 41 is covered with an upper heel net 45. At this time, the upper rod spacers 43 are disposed at the four corners of each rod 44, and the lower piece 48 of the upper rod spacer 43 is interposed between the bottom surface 46 and the rod 44. Thereby, the cage 44 is supported at a predetermined height (for example, 20 mm) from the bottom surface 46 of the upper cage breeding container 41. Further, the upper piece 49 of the upper collar spacer 43 is inserted into the lattices at the four corners of each collar, whereby the upper collar spacer 43 is attached to each collar 44.

  The assembled upper container 41 is placed in an indoor environment adjusted to a temperature of about 25 ° C. and a relative humidity of about 50%. Climb the ridge 44 from the bottom surface 42 and make a ridge in the lattice of the ridge 44.

  At this time, since the opening on the upper surface of the upper cage breeding container 41 is covered with the upper cage net 45, the cage can be prevented from escaping from the upper cage breeding container 41. In addition, since the heel 44 is supported on the bottom surface 46 via the upper heel spacer 43, a space can be secured between the heel 44 and the bottom surface 46, so that the urine and feces that have fallen on the bottom surface 46 cause It can prevent getting dirty. Furthermore, when the inner surface of the upper cage breeding container 41 is water-repellent, there is no possibility that the urine of the kite penetrates into the upper cage breeding container 41 and leaks to the outside. Furthermore, because the upper cage breeding container 41 is set to a low height (for example, 50 mm), it can be stacked on a rack or the like in multiple stages, making it possible to produce a large number of kites in a small space, and producing kites. Efficiency can be increased.

  According to the cage breeding tool and breeding method according to the above-described embodiment of the present invention, the vinyl bag 13 and the vinyl sheet 24 are attached to and detached from the breeding containers 11 and 21, and the shape and structure of the breeding containers 11, 21 and 41 are used. It is possible to easily manage the breeding environment of the salmon (moisturizing and drying the feed, etc.), simplifying the breeding management work of the salmon and improving the production efficiency. Furthermore, since it is not necessary to install a humidification facility or the like in order to control the relative humidity that is important as a breeding environment for salmon, the initial cost and running cost can be reduced.

  The breeding containers 11, 21, 41 are made of paper or cardboard and can be used disposable. Therefore, by using a new breeding container 11, 21, 41 for each breeding of the pupa, it is possible to prevent the pupae from being infected with a disease, and it is not necessary to clean the breeding containers 11, 21, 41. .

  Moreover, since the breeding cages 10, 20, and 40 are made of a lightweight material and are compactly formed and can be easily handled, labor saving and efficiency of the breeding management work can be further improved. .
