Description

  The present invention mainly relates to an apparatus for breeding and observing stag beetle larvae.

  Patent Document 1 discloses a device for raising and monitoring larvae of beetles such as stag beetles. This technique is characterized by a structure in which two transparent plates with a predetermined interval are inserted into a slit of a support plate to form an observation room, and this is detachably attached to a transparent breeding case. A mat and larvae are placed in this observation room from above, and are reared while observing the larvae in the nest through the rearing case and transparent plate. After the larvae have transformed into adults, the transparent plate and support plate are removed and the adults are raised. It can be reared in a case.

  By the way, since the width of the observation room is fixed in this technique, the size of the grown larvae nest is predicted in advance so that even if the larva grows large, it can operate without problems. It is necessary to increase the interval between them. However, when breeding is started from the first instar larvae, the larvae body is still small, so that the cross section of the nest does not appear on the surface of the transparent plate, and the larvae cannot be observed unless they grow to some extent.

It is also possible to form a plurality of slits on the support plate and replace the transparent plate with other slits to increase the spacing between the transparent plates along the growth of the larvae. It was necessary to take out the larvae once, and even if it was done carefully, the nest broke each time and the larvae were damaged or shocked.

  As shown in FIGS. 1 and 2, the larva breeding observation apparatus 1 of the present embodiment is arranged in a vertical orientation with a transparent plastic thin outer box 2 and an inner box 3 open on one side so that the open surfaces face each other. The inside box 3 is slidably inserted inside the outside box 2 to form a breeding room 4 into which the mat M and the larva B are placed. The overlapping portions of the outer box 2 and the inner box 3 are in close contact with each other so that the mat M does not leak to the outside.

  An elliptical slide hole 2a and a scale 2b are formed on the upper and lower sides of the left and right side surfaces of the outer box 2, and the screw 3b is fixed to the screw hole 3a screwed into the inner box 3 through the slide hole 2a. The slide position can be held at four locations. The upper surfaces of the outer box 2 and the inner box 3 are opened so that the mat M can be replenished and moisture can be replenished. The depth of the breeding room 4 can be adjusted within a range of 1 to 5 cm.

  A water heater 5 is integrally attached to the lower part of the outer box 2. The water heater 5 is formed with a water inlet 5a and a water outlet 5b each having a stopper 5c on the front surface, and an underwater 55W heater 5d driven by a 100V power source is arranged in a stand 5e, and the power cord 5g is a water heater. 5 can be attached in a detachable manner through connecting portions 5f and 5i having magnets on the side surfaces.

  In this embodiment, as shown in FIG. 5, the larva breeding observation apparatus 1 is laid down, the plug 5c of the water heater 5 is removed, and water W is fully poured from the water injection port 5a by means of, for example, a tube 7 and the plug 5c. Block with. At this time, if the drain outlet 5b is also opened, water can be poured smoothly while the air is removed. Subsequently, the outer box 2 is removed as shown in FIG. 6 (a), the mat M and several larvae B are put into the inner box 3, and the outer box 2 is covered from above as shown in FIG. 6 (b). Wear the original state. The inner box 3 is fixed with a screw 3b at the position of the scale 2b at the leftmost end (the rightmost end on the left side), and the depth of the breeding room 4 is made the narrowest.

  The larva breeding observation apparatus 1 is set up on two stands 6, and the connection portion 5 i of the power cord 5 g with the plug 5 h inserted into an outlet (not shown) is magnetically attached to the connection portion 5 f of the water heater 5. The water W is heated to 40-50 ° C. and the mat M in the breeding room 4 is heated from below. The temperature of the mat M is different between the upper and lower positions, and the larva B moves to the position of the desired temperature, eats the mat M, and creates a nest Ma with feces and body fluids on the spot. In this state, a cross section of the nest Ma appears on the surface of the outer box 2 as shown in FIGS.

  After that, when the larva B grows and becomes slightly larger, the screw 3b is loosened as shown in FIG. 7 (b), and the inner box 3 is gently slid outward while confirming the four scales 2b. Extend the depth of the chamber 4 and retighten the screws 3b. At this time, the mat M flows and fills the gap formed by expansion. The inner wall of the nest Ma is solidified with feces and body fluids, and is not easily broken by slight shaking caused by the sliding of the inner box 3. Further, by accurately adjusting the slide amount of the inner box 3 with the four scales 2b, the depth of the breeding room 4 becomes the same everywhere, and the larva B can move anywhere without any influence on the breeding room 4.

  The larva B further eats the mat M and gradually grows the nest Ma while growing to 1 to 3 years old, but since the depth of the breeding room 4 has been expanded in advance, the body of the larva B contacts the inner surface of the outer box 2 The cross section of the nest Ma always appears on the surface of the outer box 2 and observation can be continued. When the third-instar larva matures, it hatches in about a month, and the adult adult that has emerged will continue to be raised until it starts its activity, and when it becomes active, it will be transferred to a general breeding case.

  In this way, the grown larva B comes into contact with the inner surface of the outer box 2 by sliding the inner box 3 outward along the growth of the larva B and adjusting the depth of the breeding room 4 little by little in the enlargement direction. Thus, the cross-section of the nest Ma always appeared on the surface of the outer box 2 without being affected, and the entire growth process of the larva B can be reliably observed.
