Description

  The present invention relates to a container containing a centipede poison bait capable of efficiently guiding and feeding the centipede to the poison bait.

  Centipedes inhabit the fallen leaves of the forest and prey on small insects. In Japan, they are distributed in Honshu, Shikoku, and Kyushu. Tobism cadets with a body length of 80 to 150 mm are known. These centipedes have jaws and limbs with poisonous glands in the first torso and use them to catch insects and protect themselves from enemies. Normally, centipedes inhabit forests as described above, but may invade people's gardens and houses for the purpose of seeking food depending on changes in the natural environment. Therefore, if a person inadvertently touches a centipede, it may be bitten by the centipede, which may be accompanied by strong pain due to poison.

  Under such circumstances, arthropod repellents for preventing arthropods such as centipedes from entering a house or the like are known (for example, see Patent Document 1). If this arthropod repellent is applied and used in a place where invasion is expected, it is expected to prevent intrusion into the human living environment and prevent biting.

JP 2002-145704 A

  However, the invasion preventing effect by the repellent is not always sufficient, and contact may occur if the centipede enters the living environment of a person through the gap of the repellent. Then, bite caused by contact with the centipede may occur. Therefore, pretreatment of the repellent in a wide range where the centipede is likely to invade so that the centipede does not pass through the gap of the repellent is very troublesome and very troublesome.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a container containing a centipede poisonous bait that allows the centipede to feed a poison bait and kill insects instead of repelling the centipede. is there.
The container containing a poisonous bait for centipedes according to the present invention has been completed as a result of various studies on the habit and behavior of centipedes.
Usually, ants and cockroaches have a habit of gathering and eating food if they are placed on a flat surface such as the ground or floor. However, the centipede has found that it is not eaten only by placing food on a flat surface such as the ground or floor. Further investigation of this behavior and behavior revealed that the centipede does not recognize the bait even if it touches the antenna while moving, but recognizes it as an obstacle and takes action to avoid it. Inferred. Then, when the antenna of the centipede touched the mouth without touching the food, the centipede found that it eats the food. The container containing the poisonous bait for centipedes according to the present invention is made based on such behavior and behavior of centipedes.

The above object of the present invention is achieved by the following configurations (1) and (2).
(1) Poisonous bait to be eaten by centipede, poisonous bait receiving recess for receiving the poisonous bait, and extending from the entire periphery of the poisonous bait receiving recess to the mounting surface on the outer peripheral side, with a predetermined inclination angle enclose, centipede a centipede poison bait container filled with, a container body and a possible inclined portion approaching the poison bait from the entire circumference, beyond the height of the top portion of the inclined portion, and, A container containing centipede poison bait, wherein the poison bait is accommodated in the poison bait accommodation recess so as not to exceed a virtual extension surface formed on an extended line of an inclination angle of the inclined portion.

  According to the container for centipede poison bait (hereinafter simply abbreviated as “container”) having the configuration of (1) above, when the centipede reaches the inclined portion of the container, the centipede has the antennae angle. It will turn diagonally upward. If the centipede proceeds as it is, the poison bait is accommodated in the poison bait accommodation recess so as not to exceed the virtual extension surface formed on the extended line of the inclination angle of the inclined portion, so that the antennae of the centipede does not touch the bait, The centipede's mouth gets close to the food, so the centipede can eat it.

(2) A container containing a centipede poison bait having the structure of (1) above, wherein the inclination angle is 45 ° or less from a mounting surface on which the container body is installed. container.

According to the container for poisonous feed for centipedes having the configuration of (2) above, the centipede climbs this inclined portion because the inclined angle is 45 ° or less. Therefore, the centipede can create a state where the feed approaches the mouth of the centipede without touching the feed.
However, when the inclined portion is 60 ° or more, the antennae of the centipede may come into contact with the inclined portion, and it may be mistaken for an obstacle and not climb the inclined portion.

  According to the container for poisonous bait for centipede according to the present invention, the centipede can be efficiently guided to the poisonous bait and eaten as described above. Can easily and effectively control centipedes.

  Although the present invention has been briefly described above, modes for carrying out the present invention (hereinafter referred to as “embodiments”) will be described in detail with reference to the drawings.

It is a figure for demonstrating the behavior and action of a centipede, and is a figure which shows the state which a centipede does not eat the food which touches the antenna of a centipede. It is a disassembled perspective view of the container containing poisonous bait for centipedes according to an embodiment of the present invention. FIG. 3 is an assembled perspective view and a front view of the container containing poisonous bait for centipede shown in FIG. 2. It is the bottom view which looked at the roof body shown in FIG. 2 from the lower side. It is a figure for demonstrating the positional relationship of the inclination part of a container, a bait | feed, the antenna of a centipede, and the mouth of a centipede in the container containing the poison bait for centipedes according to the present invention. (A) is a figure explaining the accommodation method which concerns on this invention of a poison bait about two types of inclination parts from which an inclination angle differs, (b) is two types of inclination from which an centipede does not eat, and an inclination angle differs It is a figure explaining a part.

Embodiments according to the present invention will be described below with reference to the drawings.
As shown in FIG. 1, the centipede 13 has a pair of antennal 15 at the tip of the head 23. A plurality of trunks 25 are connected to the rear of the head 23, and each trunk 25 has a pair of limbs 27 on both sides. The first trunk 29 has a pair of limbs 31 having a poisonous gland (not shown).
And as a result of studying the habit and behavior of the centipede 13, the centipede 13 that moves the placement surface (floor or ground) 19 by the limbs 27 is the food 11a that is a favorite food of the centipede 13. When the antenna 15 touches for the first time, the centipede 13 shows an avoiding action and does not try to eat the bait 11a.

Further pursuing, the centipede 13 does not recognize it as the bait 11a even if its antennae tip 21 touches the bait 11a, recognizes it as an obstacle, and proceeds to avoid this. It is inferred that it proceeds without touching the bait 11a, and when the bait 11a first touches the mouth 17 of the centipede 13, it is recognized as the bait 11a.
Therefore, the container 33 containing the poisonous bait for centipede according to the present invention is based on the behavior and behavior of the centipede 13 and the antenna 15 of the centipede 13 does not touch the bait 11a, Ingeniously designed to touch the bait 11a.

Based on FIGS. 2-4, the container 33 containing the poisonous bait for centipedes which concerns on one Embodiment of this invention is demonstrated.
The container 33 containing centipede poison bait according to the present embodiment includes a container body 37 and a roof body 35 covering the container body 37. The container body 37 includes a poison bait accommodation recess 39 in which the poison bait 11 serving as a bait is accommodated, and an inclined portion 61 extending from the entire periphery of the poison bait accommodation recess 39 to the mounting surface 19 on the outer peripheral side at a predetermined angle. And having.

  In the container main body 37, the peripheral wall portion 45 stands around the bottom plate portion 43. In the present embodiment, the bottom plate portion 43 is formed in a square shape. In the illustrated example, it is a square. The peripheral wall portion 45 is continuous along each side of the bottom plate portion 43 to form a concave space in the central portion. This concave space becomes the poison bait accommodation recess 39. In the cross-sectional shape of the surface perpendicular to the extending direction, the peripheral wall portion 45 has a walking surface portion 41 on the outer side and an inner wall surface portion 47 on the inner side. A top flat surface 49 parallel to the bottom plate portion 43 is formed between the walking surface portion 41 and the accommodating portion inner wall surface portion 47 with a slight width.

  At the four corners of the peripheral wall portion 45, the roof body support shaft 51 is erected so that the axis is perpendicular to the bottom plate portion 43. The roof body support shaft 51 is a tapered shaft 53 whose tip end is tapered. In the base portion of the roof body support shaft 51, the upper end surface 55 is higher than the top flat surface 49. A partition wall 57 is provided upright at each corner of the peripheral wall 45 so as to stand up from the top flat surface 49 and have the same height as the upper end surface 55 of the base of the roof body support shaft 51. The partition wall 57 is formed in a direction along the diagonal line of the bottom plate portion 43.

The poison bait 11 is accommodated in the poison bait accommodation recess 39. The poison bait 11 includes an attractant, an excipient, an accidental food inhibitor, a preservative, a pH adjuster, and the like. The poison bait 11 becomes, for example, a gel-like solid. The poison bait 11 is disposed so as not to exceed the virtual extension surface S formed on the extension line of the inclined portion 61 with the inclination angle of 45 °.
Moreover, a protective film (not shown) or the like that is peeled off at the time of use can be attached to the upper end surface of the poison bait. The protective film reduces damage due to drying of the poison bait 11 and contact with foreign matter before use. Of course, the poison bait 11 can be accommodated in a sealed bag, opened at the time of use, and accommodated in the poison bait accommodation recess 39 of the container body 37.

  In addition, a plurality of fixed walls 59 are erected in the radial direction on the bottom plate portion 43 serving as the bottom of the poison bait containing recess 39. The fixed wall 59 can be embedded in the poison bait 11 to enhance the retention of the poison bait 11 with respect to the container body 37.

  In the container main body 37 according to the present embodiment, the walking surface portion 41 extending from the entire periphery of the poison bait accommodation recess 39 to the placement surface 19 that is the placement surface on the outer peripheral side is provided on the poison bait 11 from the placement surface 19. The slope 61 has an upward slope toward the top, and a top flat surface 49 is formed on the top of the slope 61. The top flat surface 49 serves as a pasting allowance when the above-described protective film is pasted on the container body 37, and the width is preferably 10 mm or less. When the width exceeds 10 mm, when the head 23 of the centipede 13 reaches the top flat surface 49, the antennae 15 may turn to the horizontal, and there is a possibility of taking action to avoid. Of course, in this embodiment, the walking surface portion 41 has the top flat surface 49, but the top flat surface 49 may be omitted. The height L of the walking surface portion 41 is preferably about 4 to 10 mm.

  The roof body 35 that covers the top of the container body 37 is formed in a square having substantially the same size as the bottom plate portion 43. The upper surface of the roof body 35 is formed with an inclined gradient from the central portion toward each side portion. Thereby, rainwater etc. are drained well. Cylindrical struts 65 are suspended from each corner of the lower surface of the roof body 35. As shown in FIG. 4, the taper shaft 53 of the roof body support shaft 51 in the container body 37 is inserted into the lower surface opening hole 67 of the support column 65. The roof body 35 constitutes a roof integrally with the container body 37 by fitting the respective support portions 65 to the roof body support shaft 51.

  A roof body side partition wall 69 connected to the support column 65 is suspended from the roof body 35 so as to coincide with the partition wall 57 of the container body 37. Therefore, when the roof body 35 is assembled integrally with the container main body 37, as shown in FIGS. 3A and 3B, the roof body 35 and the top flat portion are interposed between the roof body 35 and the container main body 37. A square intrusion port 71 is formed on each side, the upper and lower sides being sandwiched by the surface 49 and the left and right sides being sandwiched by the partition wall 57 and the roof body side partition wall 69. Here, it is desirable that the entry port 71 has an entry port width W of 20 mm or more and a height A of 10 mm or more.

Each of the container main body 37 and the roof body 35 is made of a synthetic resin (for example, polyethylene, polypropylene, polyester, polystyrene, polycarbonate, etc.), and may be transparent, translucent, or opaque. The container body 37 and the roof body 35 may be made of different materials.
Various additives such as an antistatic agent, an ultraviolet ray preventing agent, and an antifungal agent may be added to the synthetic resin.
The shape and size of the container body 37 and the roof body 35 are not particularly limited, and may be a rectangle, a circle, an ellipse, or the like in addition to the square in the figure. The roof body 35 may have a dome shape, an inverted saddle shape, or the like.
The joint between the container body 37 and the roof body 35 may be connected by ultrasonic welding or a thin hinge other than the above-described fitting structure. Of course, the container 33 containing poisonous bait for centipede according to this embodiment can be used with the roof 35 removed, such as when used indoors.

Next, how to effectively store the poison bait 11 accommodated in the centipede poison-containing container 33 having the above-described configuration will be described with reference to FIG.
In FIG. 5, the container main body 37 is provided with a poison bait accommodation recess 39 for accommodating the poison bait 11 in the center, and an inclined portion 61 surrounds the poison bait accommodation recess 39 with a predetermined inclination angle. In the present embodiment, the inclination angle θ of the inclined portion 61 is 45 °.
The amount of the poison bait 11 accommodated in the poison bait accommodation recess 39 exceeds the virtual extension surface S (in this embodiment, a quadrangular pyramid surface) formed on the extension line of the inclination angle 45 ° formed by the inclination portion 61. There is no such amount.
By doing in this way, when the centipede 13 starts to climb the inclined portion 61 having an inclination angle of 45 °, the antennal tip portion 21 is formed even if the head 23 of the centipede 13 approaches the top of the inclined portion 61 because there is an inclination. The poison bait 11 is not touched. When the centipede 13 reaches the top, the mouth 17 of the centipede 13 approaches the poison bait 11.

FIG. 6 is a diagram for explaining the effective accommodation method of the poison bait 11 in (a) and the ineffective accommodation method in (b). In both figures, (1) shows the container 33 of the inclined part 61 whose inclination angle is 45 °, and (2) shows the container 33 of the inclined part 61 whose inclination angle is smaller than 45 °.
6 (a) and 6 (1), the poison bait 11 is provided in an amount that does not exceed the virtual extension surface S formed on the extension line of the inclined portion 61 of the container 33 with an inclination angle of 45 °. By doing in this way, when the centipede 13 reaches the top of the inclined portion 61, the mouth 17 of the centipede 13 approaches the poison bait 11 without the antennal tip 21 of the centipede 13 coming into contact with the poison bait 11. Therefore, the probability of eating poisonous bait 11 is increased.
6 (a) and (2), even when the container 33 is a container in which the inclination angle of the inclined portion 61 is smaller than 45 °, the poisonous bait 11 also exceeds the virtual extension surface S formed on the extension line. There is no amount installed. By doing in this way, since the mouth 17 of the centipede 13 first approaches the poison bait 11, the probability of eating the poison bait 11 increases.
On the other hand, in (b) and (1) of FIG. 6, the poisonous bait 11 is installed with a large amount of the poisonous bait 11 beyond the virtual extension surface S formed on the extension line of the inclined portion 61 of the inclined portion 61 of the container 33. Has been. In this way, when the centipede 13 reaches the top of the inclined portion 61, the antennal tip 21 of the centipede 13 comes into contact with the poison bait 11, and the centipede 13 exhibits a repellent reaction, and as shown in FIG. I will not try to eat Agent 11.
6 (b) and (2), even when the container 33 having the inclination angle of the inclined portion 61 smaller than 45 ° is used, the amount of the poison bait 11 exceeds the virtual extension surface S that is also formed on the extension line. Is installed, the antennal tip 21 of the centipede 13 comes into contact with the poison bait 11, the centipede 13 shows a repellent reaction, and the poison bait 11 cannot be eaten.

Moreover, the container 33 containing poisonous bait for centipedes according to this embodiment includes a roof body 35 that covers the top of the container body 37. Therefore, when the container body 37 is installed outdoors, it is possible to prevent foreign matters such as rain, dirt, and fallen leaves from entering the poison bait containing recess 39 by attaching the roof body 35. Thereby, the efficacy of the poison bait 11 can be maintained over a long period of time.
Therefore, according to the container 33 for poisonous feed for centipedes according to the present embodiment, the eating property for the centipede 13 can be dramatically improved.

Here, the characteristics of the embodiment of the container for poisonous bait for centipede according to the present invention described above are briefly summarized and listed below.
[1] A container body comprising a poison bait 11 to be fed by the centipede 13, a poison bait accommodating recess 39 for accommodating the poison bait 11, and an inclined portion 61 surrounding the periphery of the poison bait accommodating recess 39 at a predetermined inclination angle. 37, a container 33 containing a centipede poison bait,
A container containing a centipede poison bait, wherein the poison bait 11 is accommodated in the poison bait accommodation recess 39 so as not to exceed a virtual extension surface S formed on an extension line of an inclination angle of the inclined portion 61. 33.
[2] Centipede containing container 33 for poisonous centipede configured as described in [1] above, wherein the inclination angle is 45 ° or less from the mounting surface 19 on which the container body 37 is installed. Container 33 with poison bait.

In addition, this invention is not limited to embodiment mentioned above, A deformation | transformation, improvement, etc. are possible suitably. In addition, the material, shape, dimensions, number, arrangement location, and the like of each component in the above-described embodiment are arbitrary and are not limited as long as the present invention can be achieved.
For example, in the above embodiment, since the bottom plate portion 43 of the container body 37 is formed in a square shape, the virtual extension surface S formed on the extension line of the inclination angle of the inclined portion 61 is formed in a quadrangular pyramid surface. However, when the bottom plate portion is formed in a circular shape, the virtual extension surface S is formed in a conical surface. Thus, it goes without saying that the inclined portion and the virtual extension surface of the present invention can take various shapes based on the spirit of the present invention.

(Example)
Next, when the container 33 containing centipede poison bait having the above-described configuration is used (see FIG. 5), and when the bait 11a having an upper end height of 7 mm is directly installed on the placement surface 19 (see FIG. 1). The result of examining the presence or absence of eating by centipede will be explained.

[Prescription]
The prescription of the bait 11a was as shown in Table 1 below.

[Container for poisonous centipede]
As shown in FIG. 3B, a container 33 containing a centipede poison bait with a height A of the entry port 71 of 10 mm, a height L of the walking surface portion 41 of 7 mm, and a lateral width W of the entry port 71 of 20 mm was used. .
The bait 11a is housed in the poison bait housing recess 39 so that the bait 11a has a marginal amount that does not exceed the virtual extension surface S formed on the extended line of the inclination angle 45 ° formed by the inclined portion 61. .

[Test method]
Place soil in a plastic bat 50cm long, 30cm wide and 40cm high, and place the specimen (the bait 11a or the bait 11a contained in the container 33 containing the poison bait for centipedes) along the wall of the bat. installed.
I released one Aozkade in a bat and watched it walk along the wall.
When contacting the specimen, it was confirmed whether or not to eat the bait 11a.
The results are shown in Table 2 below. In Table 2, “x” indicates a case where the sample was in contact with the sample bait 11a but was not eaten, and “◯” indicates a case where the sample was in contact with the sample bait 11a.

As shown in Table 2, in the specimen in which the bait 11a was directly placed on the placement surface 19, the number of times of eating was only once with respect to the contact with the six specimens n1 to n6.
In the sample using the container 33 containing the poisonous bait for centipede, the number of times of eating was 6 times with respect to the contact of 6 samples of n1 to n6.
In the specimen in which the bait 11a was directly placed on the placement surface 19, it was confirmed that the number of times of eating decreased due to the repelling reaction caused by the antennae tip 21 touching the bait 11a.
In the specimen using the centipede poison bait container 33, it was found that the number of times of eating dramatically increases when the mouth 17 comes into contact with the bait 11a before the antenna tip 21.

[Inclination angle of the inclined part used as a walking surface]
Next, the inclination angle θ of the inclined portion as the specimen was changed to 15 °, 30 °, 45 °, 60 °, and 90 °, and the inclination portion passing rate of the centipede 13 was examined.
Soil was laid in a plastic bat having a length of 50 cm, a width of 30 cm, and a height of 40 cm, and a slope table on which the bait 11a having the formulation shown in Table 1 was placed was placed along the wall of the bat.
The slope table was prepared using a polystyrene foam plate so that the width of the inclined portion was 30 mm and the length was 100 mm.
One Aoskadeka was gently released into the bat, and the centipede 13 was observed passing through the slope table as a specimen.
The results are shown in Table 3 below. In Table 6, “◯” indicates a case where the slope portion of the slope base is climbed, and “×” indicates a case where the slope portion of the slope base is tilted or turned back without climbing.

As shown in Table 3, when the slope angle θ is 60 ° or more, the slope passage rate is remarkably reduced.
It has been found that when the slope angle θ is smaller than 60 °, desirably 45 ° or less, the slope passage rate is increased. Therefore, the inclination angle of the walking surface portion 41 in the container main body 37 is desirably 45 ° or less from the installation surface.

[How to contain the bait]
