TECHNICAL FIELD OF THE INVENTION
The present invention relates to a breeding method and a breeding container for subculturing and managing microscopic organisms such as mites, and in particular, a container-like sorting device for selecting ticks and the like, a breeding container that can easily take out mites and the like out of the container. The present invention relates to a collection device for collecting ticks and the like in a breeding container, a container for laying eggs such as ticks, and a breeding method using these sorting devices, breeding containers and the like.
[0002]
[Prior art]
Conventionally, as a tool to subculture and breed this kind of small creatures such as mites, put a wet cotton in a large test tube, lay a sponge on it, put a tick on it By attaching a cotton plug, the container was used as a tick breeding container or an egg-laying container. In addition, when exchanging the breeding container and attaching the mites by the ear bag method, the mites were gradually removed from the container into bats or ear bags. Here, the tick attachment by the ear bag method is to put a tick in a cloth bag or the like and attach it to the ears of livestock or the like to cause blood loss.
[0003]
[Problems to be solved by the invention]
By the way, in the method of breeding by subculture management with the breeding equipment as described above, ticks are vulnerable to drying and mold, and therefore, it is necessary to prevent drying and prevent the occurrence of mold due to shells and excrement due to the removal of mites in the breeding container. Therefore, it is necessary to appropriately replace the breeding container with a new breeding container. However, there is a problem that it is difficult to remove mites attached to the breeding container and the working efficiency is low.
[0004]
In addition, when sucking and collecting ticks into a new breeding container, it is necessary to temporarily remove the ticks from the container, but there is a problem in that the ticks are highly likely to escape due to escape from the clouds. A suction device is used for sucking and collecting ticks. However, there is a problem in that the ticks gather at the bottom of the suction joint connected to a container such as a test tube, and there is a high possibility that the ticks are escaped when the suction joint and the stopper are replaced. Furthermore, in order to carry out the systematic passage of ticks, it is necessary to put one saturating adult mite in each breeding container and manage it, and there is a problem that the breeding space is increased.
[0005]
The present invention has been made in view of such a problem, and an object of the present invention is to easily, safely, and quickly carry out systematic subculture management work of microscopic organisms such as mites, An object of the present invention is to provide a breeding method that can efficiently breed mites and the like. It is another object of the present invention to provide an instrument for selecting and collecting microscopic organisms such as mites used in the above-described breeding method, and a breeding container and an egg-laying container capable of breeding efficiently.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, the method of breeding small creatures such as ticks according to the present invention comprises collecting small creatures such as hatched ticks by spontaneously moving them from unnecessary materials such as dead bodies by placing them in a sorting device, The collected micro-organisms are bred in a breeding container for a predetermined period of time, and the grown micro-organisms are laid in a spawning container having a plurality of spawning spaces arranged side by side. For the sorting of ticks and the like, a tick or the like is put into the center of a sorting tool having a wall portion containing water on the outer periphery with a container-like sorting tool and separated from unnecessary substances such as dead bodies. The collection of mites or the like may be carried out by directly sucking them into the incubator using a suction device or the like, or may be collected using a dropper or the like and put in the incubator.
[0007]
According to this breeding method, ticks have a property of avoiding moisture while being cloudy, so that they can be easily separated from dead matter such as dead bodies, excreta, and shed shells in the sorting container. In addition, the breeding container can be easily sucked and put into the breeding container, and the breeding container can be easily replaced for the purpose of preventing contamination. Therefore, the breeding container is bred in a clean environment, and can be prevented from weakening or dying. The ticks and the like that have been bred and grown for a predetermined period are taken out of the breeding container and put into an egg-laying container, so that the egg-laying can be intensively managed in a small space. In this way, it is easy to sort out ticks, replace breeding containers, and move them to egg-laying containers, so that work efficiency is good, the inside of breeding containers can be kept clean, and the passage control of ticks etc. can be done safely and quickly. Can be done.
[0008]
Further, the sorting device according to the present invention is used in the breeding method described above, is a container-like sorting device that separates small creatures such as mites from unnecessary matters such as dead bodies, and has a space in the center, It is characterized in that it has a wall portion containing a substance for avoiding microscopic organisms on the outer peripheral portion. As a substance that avoids microscopic organisms, substances such as water and alcohol that are not preferred by microscopic organisms such as mites are used. This sorting device is preferably a white and flat circular container, and it is preferable that a water-absorbing material such as a sponge is inserted between the outer peripheral wall and the inner peripheral wall to form a wall containing moisture.
[0009]
According to the sorting device configured in this way, when a large number of ticks during breeding are put into the central space, the ticks move in clouds in all directions, and when approaching the wall containing moisture on the outer circumference, the moisture is removed. Avoid and retreat. For this reason, mites can be easily selected and separated from the dead body, excrement, shed shells and the like in the central portion, and escape can be prevented. When the temperature is high, the mites move around actively.However, when the temperature is low, the activities are suppressed or stopped, so the moisture and the like on the outer peripheral wall are cooled by using the sorting device of the present invention under cooling, so that the mites move. Therefore, the mites can be further efficiently separated and separated from unnecessary substances. In addition, when alcohol is appropriately contained in the wall, the alcohol evaporates to remove heat from the outer peripheral wall, thereby effectively isolating mites by the effect of lowering the temperature of the wall. Since alcohol is harmful to mites, it is preferable to use it at the lowest possible concentration.
[0010]
The breeding container according to the present invention is used in the breeding method described above, and is a breeding container for breeding small creatures such as ticks, and has a cylindrical case and a bottom for closing an opening at a lower end of the cylindrical case.

The breeding container preferably further includes a piston which is inserted from below into the cylindrical case with the bottom plug and the water supply means removed, and which can push up the breeding floor and move out of the cylindrical case.
[0011]
According to this breeding container, it is possible to easily supply water while the mite remains in the container, and it is possible to keep the inside of the container at an appropriate humidity, so that breeding management of ticks and the like can be easily performed. it can. Although the ticks during breeding are attached to the inner wall of the cylindrical case, the breeding floor can be pushed up by using a piston and taken out of the container at a time, and the cylindrical case can be easily cleaned.
[0012]
The collection device according to the present invention is a collection device that is attached to the cylindrical case of the breeding container and collects small organisms, and has a wall that can be inserted into the cylindrical case and has a downwardly opened holder, A lower plug that closes the lower opening of the holder to form an internal space; an upper plug that is connected to the upper part of the holder to close the opening of the cylindrical case; and a lower plug that is formed from below on the wall surface of the holder to reach the inner space. And a pipe penetrating the upper and lower plugs and a pipe penetrating the upper plug.
[0013]
According to the configuration of this collecting instrument, when placing the ticks separated by spontaneous movement from unnecessary objects into the breeding container in the sorting container for sorting the ticks and the like, a suction device is connected to a pipe penetrating the upper stopper, When a tube or the like connected to a pipe penetrating the lower stopper is brought close to the mites, the mites are inserted into the upper space of the breeding floor of the breeding container through a pipe penetrating to the lower stopper via the tube, and a collecting device. The collecting device can be removed from the cylindrical case while holding the lower stopper in the cylindrical case by inserting a tool such as tweezers into the notch of the holder, thereby preventing the mites from escaping out of the breeding container. .

[0016]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, as a breeding container and a sorting device used in the method for breeding small creatures such as mites according to the present invention, first, an embodiment of a sorting container as a container-like device for sorting ticks will be described in detail based on the drawings. . FIG. 1 is a perspective view of a sorting container according to the present embodiment, and FIG. 2 is a sectional view taken along line AA of FIG.
[0017]
In FIGS. 1 and 2, the sorting container 1 temporarily isolates mites in the container by utilizing the property of mites to avoid water when sorting and collecting microscopic organisms such as Tickle mite. The sorting container 1 has a container shape composed of a bottom wall 2 and an outer peripheral wall 3 made of plastic or metal. The inner peripheral wall 4 has a predetermined distance from the outer peripheral wall 3 to the inside. Is formed, and the height of the inner peripheral wall 4 is set smaller than that of the outer peripheral wall 3. The space inside the inner peripheral wall 4 serves as a mite isolation part 5. If the sorting container 1 is formed in a circular flat container shape from, for example, a white synthetic resin, it is convenient to easily find mites.
[0018]
The outer peripheral side of the mite isolation part 5 is a ring-shaped space sandwiched between the outer peripheral wall 3 and the inner peripheral wall 4, and a ring-shaped sponge 6 is fitted into this space as a water-absorbing material. The sponge 6 is sufficiently hydrated when used. As described above, the sorting container 1 has the space of the separating part 5 in the center part, and the ring-shaped sponge 6 containing water is located on the outer peripheral part to form a wall. The sponge 6 may contain an alcohol having a property to avoid mites.
[0019]
The height of the sponge 6 is lower than the outer peripheral wall 3 and higher than the inner peripheral wall 4. The inner peripheral wall 4 has a certain height in order to prevent the mites from climbing up their backs and forming a bridge to escape. The water-absorbing material is not limited to a sponge, and any material such as cotton or glass wool may be used as long as it sufficiently contains water. The sponge 6 preferably has a protruding portion 6a that covers the upper end surface of the inner peripheral wall 4 as shown in FIG.
[0020]
The operation of the sorting container 1 for sorting ticks and the like according to the present embodiment configured as described above will be described below. When breeding ticks are placed in the isolation part 5 at the center of the sorting container 1, living ticks, mite carcasses, excreta of the ticks, shed shells and the like are concentrated in the center. Then, as time elapses, the mites escape in all directions, leaving only unnecessary objects in the center. When the mite that has climbed the inner peripheral wall 4 touches the sponge 6 that has absorbed water, it retreats and returns to the bottom surface, so that living mites gather around the bottom surface and are separated by spontaneous movement. For this reason, by sucking this part, the experimental mites can be separated and collected, and can be sorted out from unnecessary substances.
[0021]
Next, an example of a cylindrical rearing container as a rearing container for mites or the like will be described with reference to FIGS. The breeding container 10 includes a transparent or translucent cylindrical case 11, and a cylindrical mite floor 12 is fitted to a center of the cylindrical case 11 as a breeding floor formed of a sponge or the like. A water supply tank 13 is inserted as a water supply means so as to be in contact therewith, a bottom plug 14 supporting the water supply tank 13 is fitted and fixed to a lower end of the cylindrical case 11, and a sponge or the like is formed at an upper end of the cylindrical case 11. The air-permeable top cover 15 is fitted, and the space between the top cover 15 and the tick floor 12 is a breeding space 11a. The mite floor 12 serves to supply moisture to the breeding space 11a to prevent the mite from drying, and to receive the mites, dead mites and shells.
[0022]
As shown in FIG. 3 (c), the water supply tank 13 includes a water supply container 13a having an outer diameter that is loosely inserted into the cylindrical case 11, and a water absorption wick 13b fitted into an upper opening of the water supply container. You. The water absorption wick 13b is for sucking up water in the water supply container and supplying water to the tick floor 12 of the sponge. The upper portion is a large diameter portion fitted to the inner periphery of the water supply container 13a. A small-diameter portion 13c is provided which hangs downward from above and absorbs water, and is entirely formed of a water-absorbing material such as a sponge.
[0023]
The bottom stopper 14 is formed of a rubber stopper having a truncated cone shape, and is firmly fitted to the lower opening of the cylindrical case 11 to prevent the water supply tank 13 from dropping. The upper lid 15 is formed of sponge, cotton, or the like, and is configured to transmit air to the ticks breeding on the tick floor 12 and, when the ticks climb the inner surface of the cylindrical case 11, the cylindrical case 11 Prevents escape from inside.
[0024]
The breeding container 10 further includes a piston 16 inserted into the cylindrical case 11 shown in FIG. The upper part of the piston 16 is a push-up part 16a that fits loosely on the inner surface of the cylindrical case 11, the lower part is an operation part 16b that is pressed by a finger, and the middle part is a connection shaft part 16c. The piston 16 is removed from the bottom case 14 and the water supply tank 13 and inserted into the cylindrical case 11 from below. The piston 16 pushes up the tick floor 12 and moves out of the cylindrical case 11 as shown in FIG. It goes out. By removing the bottom plug 14 and the water supply tank 13 of the breeding container 10 and inserting the piston 16, the breeding container 10 becomes an injection type.
[0025]
Since the cylindrical rearing container 10 can be supplied with water by removing the bottom plug 14 and removing the water supply tank 13 while rearing the mites on the tick floor 12, the rearing management of the mites can be easily performed. Further, the structure is simple, and when all of them are removed, only the cylindrical case 11 is provided, so that cleaning is easy and cleanliness can be maintained. Then, when the mites during rearing are moved, the bottom plug 14 is removed, the water supply tank 13 is pulled out, the piston 16 is inserted from below, the mite floor 12 is pushed up, and the mites can be easily moved by being pushed out together with the upper lid 15. .
[0026]
By winding or wrapping the side or entire surface of the mite floor 12 with a net (not shown) made of a slippery material such as polyethylene, the tick floor can be smoothly extruded with reduced frictional resistance when sliding. That is, if the cylindrical case 11 is made of glass, the inner wall surface will be finely scratched by washing, and if the tick bed 12 is pushed up by the piston 16, friction will occur between the inner wall surface and the tick floor, and It is possible to prevent the floor from being twisted or the like, so that the mite floor 12 cannot be pushed out smoothly.
[0027]
As an embodiment of the collecting device according to the present invention, an example of a suction joint 20 attached to a cylindrical case 11 for putting a tick into a breeding container 10 shown in FIG. 3 will be described with reference to FIGS. The suction joint 20 is a joint device for efficiently collecting and placing ticks and the like in the injection-type breeding container 10. The suction joint 20 has a cylindrical wall having an outer diameter that can be inserted into the cylindrical case 11 of the breeding container 10. A container-like holder 21 having a downward opening, a lower stopper 22 formed of a sponge or the like closing the lower opening of the holder 21 and functioning as a temporary plug, a rubber stopper connected to an upper portion of the holder 21 by a set screw 21a, and the like. The upper stopper 23 is provided. One set screw 21a may be provided at the center of the holder 21, or two or more set screws may be provided on the circumference.
[0028]
The upper stopper 23 has an inverted truncated cone shape, and the outer diameter of the upper end is formed larger than the inner diameter of the cylindrical case 11 of the breeding container 10. The lower stopper 22 has a truncated cone shape, and the diameter of the lower end is formed larger than the inner diameter of the cylindrical case 11 of the breeding container 10. The lower stopper is not limited to a truncated cone, but may be formed in a columnar shape. In this case, the outer diameter of the lower stopper is formed to be larger than the inner diameter of the cylindrical case, and the lower stopper is fitted to the inner periphery of the holder and is brought into close contact with the inner wall of the cylindrical case to close the gap.
[0029]
The holder 21 is formed of transparent plastic, metal, or the like, and the lower opening is closed by a lower stopper 22 to form an internal space 24. Two cuts 25 are formed in the outer peripheral surface of the holder 21 in the axial direction from below, and the cuts 25 are formed so as to reach the internal space 24. For this reason, a tool such as tweezers can be inserted into the internal space 24 avoiding the lower stopper 22. A long suction pipe 26 penetrating the upper plug 23 also penetrates the lower plug 22. Another short suction pipe 27 penetrating through the upper plug 23 opens into the internal space 24. The suction joint 20 functions as a suction joint of a suction device (not shown) that sucks and collects mites and the like into the breeding container 10.
[0030]
The suction joint may be formed by forming the holder 21A from a cylinder and fitting the upper plug 23A to the upper opening of the holder 21A and connecting the holder 21A like a suction joint 20A shown in FIG. 5C. In this example, the number of cuts 25A formed in the holder 21A is one, but it is needless to say that two may be used.
[0031]
When the suction joint 20 is used, the upper lid 15 of the breeding container 10 shown in FIG. 3 is removed, and the lower plug 22 and the holder 21 of the suction joint 20 are opened through the upper opening of the cylindrical case 11 as shown in FIG. And the upper plug 23 is fitted. Then, an aspirator (not shown) is connected to the suction pipe 27 of the upper plug 23 by a connecting pipe, and the mites are sucked by the tube connected to the suction pipe 26. As a result, the mites are connected to the tick bed 12 and the lower plug 22 as shown by an arrow Y1. And the exhaust can be discharged as shown by an arrow Y2. When the mites are sucked into the breeding container, the water supply tank 13 is removed, and after the mites are suctioned and collected, the water supply tank 13 is inserted, and the bottom stopper 14 is fitted and fixed to the cylindrical case 11.
[0032]
After the ticks are collected by suction and placed in the breeding space 11a, the suction joint 20 is pulled up to a position where the lower stopper 22 coincides with the upper end of the cylindrical case 11, as shown in FIG. Then, a tool 28 such as tweezers is inserted into the internal space 24 through the cut 25, and the upper portion of the suction joint 20 is pulled out from the holder 21 while pressing the lower stopper 22 to prevent the movement. As a result, as shown in FIG. 6C, since the lower plug 22 remains in the cylindrical case 11, the mites are blocked by the lower plug 22 and are prevented from moving upward, so that the mites can be prevented from escaping. Since the lower stopper 22 is formed of a sponge, the hole 26a from which the suction pipe 26 penetrating through the lower stopper 22 is naturally closed by the restoring force, so that the mites can be prevented from escaping.
[0033]
As an embodiment of the egg-laying container of the present invention, an example of an egg-laying bed on which mites lay eggs will be described with reference to FIGS. The spawning bed 30 has a rectangular lower case 31 opening upward, an intermediate holder portion 32 detachably fitted into the opening of the lower case 31 to form a plurality of sections, and an upper case covering an upper portion of the intermediate holder portion. 33. The lower case 31 stores water for supplying water to the mites bred for spawning, and is formed of, for example, a rectangular plastic case.
[0034]
The intermediate holder portion 32 includes an outer peripheral wall portion 32a fitted inside the lower case 31, a bottom wall portion 32b forming an inner bottom surface of the outer peripheral wall portion, and a flange portion 32c extending outside the outer peripheral wall portion. When the flange portion 32c is in contact with the upper end of the lower case 31, a space S that is a water supply section is formed between the bottom wall portion 32b and the bottom surface of the lower case 31. A plurality of partitions used as the spawning space 35 are formed by the circumferential wall portion 32d extending upward from the bottom wall portion 32b, and in the illustrated example, 24 circumferential wall portions are formed. For example, one section located at the corner has a bottom wall portion penetrating therethrough, and serves as a water supply section 34 to the space S of the lower case 31. A through-hole 36 is formed in the center of the bottom wall 32b of each section, and the space S of the lower case 31 and the plurality of egg laying spaces 35 communicate with each other. On the lower surface of the upper case 33, a circumferential projection 33a fitted to the outer periphery of the circumferential wall portion 32d is formed to prevent the mites from escaping upward and moving to the adjacent section.
[0035]
A mesh material 37 is spread over the plurality of egg-laying spaces 35 to support the rising of ticks and prevent the ticks from rolling over. The mesh material 37 is formed, for example, by pressing gauze with a finger to form a container having an open top, but is not limited to this, and may be a container formed of synthetic resin into a mesh. In the egg-laying space 35, water supplied to the lower case 31 is evaporated and rises from the through-hole 36 to maintain an appropriate amount of water, which provides an environment suitable for egg-laying. Since the plurality of spawning spaces 35 are arranged horizontally and vertically, the mite situation and the spawning situation can be easily grasped at a glance.
[0036]
In the method for breeding small creatures such as ticks according to the present invention, as a first step, small creatures such as ticks are separated from unnecessary substances and sorted using the sorting container 1 shown in FIGS. In other words, mites weaken and die during breeding, husks scatter shedding shells, and are covered with excrement and become dirty. Live mites are screened from such a filthy environment. For example, when a tick kept in a test tube is put into the center of the sorting container 1, the tick becomes cloudy with time, and the fast-moving tick moves up the inner peripheral wall 4 and approaches the sponge 6 containing water. However, since the mites have a property of avoiding water, when they come into contact with the sponge 6, they retreat and separate and concentrate on the outer peripheral portion of the bottom surface of the sorting container 1 by spontaneous movement. As described above, the mite may be separated by including a low concentration of alcohol in the sponge 6 as the wall.
[0037]
As a second step, the mites separated on the outer periphery of the sorting container 1 are put into a column-shaped rearing container 10. At this time, the suction joint 20 is used as a collecting device that is connected to the upper opening of the breeding container 10 to suck and collect the mites. The upper stopper 23 of the suction joint 20 is fitted into the upper opening of the cylindrical case 11 of the breeding container 10, a short suction pipe 27 is connected to a suction device such as an electric suction pump, and the tube connected to the long suction pipe 26 is separated from the sorting container 1. Approach isolated ticks. When the suction device is operated, the mites are sucked into the breeding space 11a of the breeding container 10 through the tube, and the exhaust air is discharged from the short pipe through the suction device. Note that a filter may be provided in the middle of the suction pipe 27 to prevent the mites from being sucked into the suction device.
[0038]
After the mites have been inhaled into the breeding container 10, the suction joint 20 is removed from the breeding container 10. However, as described above, the suction joint 20 is pulled up, a tool 28 such as tweezers is inserted into the cut 25, and the lower stopper 22 is left. The mites can be prevented from escaping from the breeding container 10 because they can be removed in a state where the ticks are removed. The lower stopper 22 functions as the upper lid of the breeding container 10 as it is. That is, ventilation of the breeding space 11a and escape of mites are prevented.
[0039]
As a third step, ticks and the like are bred in the breeding container 10 for a predetermined period. The mites receive moisture from the water supply tank 13 in the breeding container 10 and grow in a clean state in the breeding space 11a having appropriate humidity. First, a young mite with a body length of about 0.8 mm is bred for about 4 weeks or more, and then molted and becomes a young tick when saturated, and when bred and saturated, it molts and becomes an adult mite and has a body length of 3 mm. And grow to such an extent that it can be easily confirmed visually.
[0040]
As a fourth step, the breeding container 10 is replaced as necessary in the third step in order to keep the breeding environment of the mites clean. In this case, the bottom plug 14 is removed, the water supply tank 13 is removed, the piston 16 is inserted from the lower opening of the cylindrical case 11, and the mite floor 12 is taken out from the upper opening of the cylindrical case 11. Then, using a suction device, for example, the mites are placed in the cleaned cylindrical case 11 in which a new mite bed is set, or in the new breeding container 10.
[0041]
As a fifth step, mites and the like raised and raised in the breeding container 10 are replaced with an egg-laying bed 30 which is an egg-laying container. The bottom plug 14 of the breeding container 10 is removed, the water supply tank 13 is removed, and the piston 16 is inserted into the cylindrical case 11 from below. When the piston 16 is pushed up, the tick bed 12 rises, and the tick moves upward together with the tick bed 12 and is taken out of the cylindrical case 11 while being sandwiched by the upper lid 15 or the lower stopper 22. In this manner, the mites easily taken out of the breeding container 10 by the piston 16 are sufficiently saturated and then put into each of the spawning spaces 35 of the spawning bed 30 one by one. Saturated mites have a body length of about 5 to 10 mm, and lay eggs in the spawning space 35 in thousands. In the spawning space 35, the movement of mites is prevented by the projections 33a of the upper case 33, so that individual passage management can be performed reliably.
[0042]
As described above, according to the above-described method for breeding small creatures such as ticks, it is possible to safely and quickly manage from eggs to young ticks, from young ticks to young ticks to adult ticks. In addition, mature adult mites can be engorged and individually managed and spawned in the spawning bed. Individual passage of mites and intensive management of adult mites can be easily performed, and space-saving management is possible. be able to.
[0043]
As described above, the embodiments of the present invention have been described in detail. However, the present invention is not limited to the above embodiments, and various designs may be made without departing from the spirit of the present invention described in the appended claims. Changes can be made. For example, in the column-shaped breeding container, an example of a water supply tank is shown as a water supply means, but it is also possible to prevent water from being dried by putting cotton moistened with water in a cylindrical case. In this case, when the cotton has dried, the bottom plug is removed, the cotton is taken out, and water may be supplied. The cuts of the holder of the suction joint may be provided at a plurality of locations. Although an example of a tick is shown as a small creature, it is needless to say that the present invention can be applied not only to a tick but also to a small creature such as an ant or a spider.
[0044]
Furthermore, the projection 33a is provided on the upper case 33 of the spawning bed 30 to prevent the movement of the mites, but the upper end of the circumferential wall 32d is in contact with the inner surface of the upper case 33 so that the movement of the mites is prevented. May be prevented.
