FIGS. 1 and 2 are optical microscope images and SEM images of the surface of a coral stone contained in the composition of the present invention. Hereinafter, the composition of the present invention will be described with reference to Figs. 1 and 2.

The present invention relates to a composition for woogoo attractiveness, which comprises a fossilized coral, and the coral stone has a porosity structure.

The pores of the porous structure may have an average diameter of 50 to 100 mu m.

Such a porous structure enables natural humidity control, and it is possible to create an environment in which the worms such as external parasites can live.

The above-mentioned corals refers to the corals and coral reefs that have been damaged by fossilization, weathering, and deposited on the seabed. In addition, the coral stone includes aragonite, and the crystal structure of the aragonite is orthorhombic.

The aragonite is a mineral belonging to the orthotropic system and is the same minerals as calcite, but the crystal system corresponds to different homogeneous anomalies. The appearance of the aragonite is colorless, white, purple, yellow, green and blue, transparent or translucent, and glassy.

The Ryukyu limestone, which is distinguished from the above-mentioned coral stone included in the composition of the present invention, is, for example, Ryukyu limestone. Ryukyu limestone is formed by the rising of coral reefs and is the same as the coral stone as a harmful element of the coral reef creature group, but there is a difference in crystal structure and composition. Since Ryukyu limestone is exposed to rain and the like on the land, there is no crystal structure at the time of reproduction of coral reef, and it contains calcite of hexagonal system, and is not porous but massive and lacks minerals such as magnesium. . This massive Ryukyu limestone has no porous structure, which makes it difficult to create a favorable environment for habitat.

Such coral stones can be collected from the beach, but it is not preferable from the viewpoint of nature protection, so it is preferable to collect them from the ocean. It is preferable that the above-described coral stone is used after cleaning, drying, removal of foreign matter, and particle size adjustment after collection from the sea floor.

It is preferable that the coral stone is a particle-shaped coral stone.

The average particle size of the particulate corpuscles may be 3 to 10 mm, but more preferably 5 to 7 mm.

When the average particle size of the coral stone is larger than the above range, it is difficult to manufacture a catcher because the particles are large because the particles are accommodated in the catcher. If the average particle size is smaller than the above range, the trapping ability of the catcher can be significantly reduced. There is a possibility that particles may be lost through the exposed passage of the trapper.

However, the scope of the present invention is not limited thereto, and the average particle size of the coral stone may vary depending on the size of the coral stone receiving space of the captor, the diameter of the wedge passage, or the type of insect pest .

As for the chemical composition of the above-mentioned coral stone, the above-mentioned coral stone contains 250-330 parts by weight of carbon (C) relative to 100 parts by weight of calcium (Ca); 0.1 to 0.2 parts by weight of chloride; 0.4 to 0.6 parts by weight of iron (Fe); 3.5 to 6 parts by weight of magnesium (Mg); 0.3 to 0.5 parts by weight of silicon (Si); 0.05 to 0.15 parts by weight of sodium (Na); 0.2 to 0.4 parts by weight of strontium (Sr); And 0.7 to 1.3 parts by weight of sulfur (S).

In addition, the above-mentioned acid stone may further contain 0.0005 to 0.015 part by weight of antimony (Sb) based on 100 parts by weight of calcium (Ca); 0.03 to 0.05 part by weight of potassium (K); And 0.001 to 0.005 part by weight of rubidium (Ru).

In addition, the above-mentioned coral stone preferably contains 0.001 to 0.002 parts by weight of barium (Ba) based on 100 parts by weight of calcium (Ca); 0.004 to 0.006 parts by weight of boron (B); 0.0005 to 0.0015 parts by weight of cerium (Ce); 0.0005 to 0.0015 parts by weight of neodymium (Nd); 0.0005 to 0.0015 parts by weight of phosphorus (P); 0.003 to 0.005 parts by weight praseodymium (Pr); 0.001 to 0.002 parts by weight of copper (Cu); 0.001 to 0.002 parts by weight of erbium (Er); 0.004 to 0.006 parts by weight of a fluoride; 0.005 to 0.02 parts by weight of iodine (I); 0.0005 to 0.0015 parts by weight of manganese (Mn); And more preferably at least one selected from the group consisting of

In some cases, the oxides may further contain trace elements such as arsenic, beryllium, bismuth, nickel, molybdenum, palladium, osmium, chlorine, gadolinium, lithium, tungsten, tantalum, tin, zinc, yttrium, have.

FIG. 3 is a perspective view of a catcher according to an embodiment of the present invention, FIG. 4 is an enlarged side view of part A of FIG. 3, FIG. 5 is a side view of a corrugated cardboard according to an embodiment of the present invention, Fig. Hereinafter, a catcher according to an embodiment of the present invention will be described with reference to FIGS. 3 to 5. FIG.

3 through 5, the catcher according to an embodiment of the present invention includes a body 100, 200, a hole H formed in the center of the body 100, 200, a hole cover 300, 400, (C) contained in the globular glove (C) accommodated in the glove box (H).

The main body 100 and 200 have concave and convex portions 110 and 210 having corrugated surfaces and planar supports 120, 130, 220 and 230 disposed on one side or both sides of the concave and convex portions 110 and 210, And a plurality of passageways 112 and 212 may be formed in the lateral direction between the recesses and protrusions 110 and 210 and the supports 120, 130, 220 and 230.

The main body 100, 200 is preferably a corrugated cardboard.

Accordingly, the concave and convex portions 110 and 210 correspond to the corrugated sheets 110 and 210, and the supports 120, 130, 220, and 230 correspond to the paperboard 120, 130, 220, and 230, respectively.

The corrugated cardboards 100 and 200 can be divided into a double-sided corrugated cardboard and a single-sided corrugated cardboard, and can selectively apply the type of corrugated cardboard.

The double-sided corrugated cardboard has discs disposed on both sides of the corrugated cardboard, and the single-sided corrugated cardboard means that the discs are disposed on one side of the corrugated cardboard.

The main body 100, 200 may be composed of one double-side corrugated cardboard or one-side corrugated cardboard. At this time, when the double-sided corrugated board is used as shown in the figure, the corrugated corrugated passageway can be formed about twice as much as the single-sided corrugated board. Therefore, the use of double-sided corrugated cardboard rather than single-sided corrugated cardboard can be more advantageous for increasing the probability of trapping of woogeomo, and can be more advantageous for laminating the main body.

In addition, the main bodies 100 and 200 may be formed of a plurality of stacked bodies, thereby increasing the number of the wedge-shaped passages to increase the probability of capturing the wedge, and preferably formed of a laminate of 2 to 4 layers. When a single body is used, the probability of trapping the wagumo can be lowered. If a laminate having five or more layers is applied, the volume may become large and the installation may be inconvenient, and the manufacturing cost may increase. There is a risk of emitting smoke.

Although FIG. 3 illustrates formation of a laminate in which two bodies 100 and 200 are laminated, the scope of the present invention is not limited thereto, and the laminate may have various layers as required.

The holes H are formed through the centers of the main bodies 100 and 200 and a composition C for a wedge-like attractant containing a coral stone can be accommodated in a space formed by the holes H. [

Since the composition (C) for Wakumo attractant is as described above, the details of the composition will be referred to.

The hole covers 300 and 400 cover both opening portions of the hole H to prevent the deteriorated composition C contained in the detainee from being released to the outside.

Hereinafter, with reference to FIG. 3, a catcher constructed of a double laminate according to an embodiment of the present invention will be described.

The double laminate according to an embodiment of the present invention may include a first corrugated cardboard 100, a second corrugated cardboard 200, a first hole cover 300, and a second hole cover 400.

The first corrugated cardboard 100 may have a corrugated cardboard 110 and upper corrugated cardboard 120 disposed on the corrugated cardboard 110 and a lower corrugated cardboard 130 disposed on a lower side of the corrugated cardboard 110.

4, since the corrugated sheet 110 has a corrugated surface, the corrugated sheet 110 is positioned between the upper circular sheet 120 and the lower circular sheet 130 to form a space, (112) can be formed. Therefore, the size of the wedge-shaped channel 112 can be adjusted according to the magnitude of the corrugation formed on the corrugated plate 110.

The second corrugated cardboard 200 may include a corrugated cardboard 210 and upper corrugated cardboard 120 disposed on the corrugated cardboard 210 and a lower corrugated cardboard 130 disposed on the lower side of the corrugated cardboard 210.

Since the corrugated cardboard 210 has a corrugated surface, the corrugated cardboard 210 is positioned between the upper and lower circular paperboards 220 and 230 to form a space, thereby forming a passageway 212. Therefore, the diameter of the corrugated channel 212 can be adjusted according to the magnitude of the corrugation formed on the corrugated cardboard 210.

The first corrugated cardboard 100 and the second corrugated cardboard 200 have the same area, and the holes H formed at the center may be completely overlapped with each other due to the same position and shape. The inner wall surface of the hole (H) can be connected to the outside by the wedge-shaped passage (112, 212).

The first corrugated cardboard 100 and the second corrugated cardboard 200 are laminated and the holes H formed in the center of the first corrugated cardboard 100 and the second corrugated cardboard 200 are formed in a shape and size It is preferred that they match, but they do not overlap or may not match in size. However, if the two holes H do not coincide with each other, it is preferable that both the first corrugated cardboard 100 and the second corrugated cardboard 200 have holes H, respectively.

The average diameter of the Wagome attractant composition (C) can be appropriately adjusted in consideration of the height of the inner wall surface of the hole to be accommodated, that is, the thickness of the entire retainer, and the trapping rate of the worm.

The retractor can be used as an axial retractor.

Pests captured by the captor may be applied to other external parasites in addition to Wagome. The external parasite is a parasitic parasite parasitic on the surface of the host's body, and may be one selected from among a blood-sucking insect, an amphibian, and a cyclic animal.

The captor of the present invention is characterized in that it comprises the above-described composition of the present invention for woogoo, and if it is a structure capable of attracting and capturing woogee by the composition for woogoo attractiveness, regardless of structure, shape, And can be included in the scope of the present invention.

[Test Example]

Pest Performance test

From October 2, 2016 to October 5, 2016, the poultry performance was tested at a poultry house in the poultry farm located in Sumohara City, Kanagawa Prefecture, where damage to wakumo (chicken mite, chickens)

Specifically, six captors manufactured in accordance with Example 1 and Comparative Examples 1 to 4 were randomly installed in a house, and three days later, they were recovered as sealed vinyl. One of the recovered captors of Example 1 was photographed 8.

The pellet performance was analyzed by examining the weight gain of the pellet before and after installation of the pelletizer. The results are shown in Table 2 below.

division Coral stone Particle size (mm) Ryukyu limestone lavender Before installation
(g) after installing
(g) Increase
(g) Example 1 include 5 ~ 7 - - 51.5 55.3 3.8 Comparative Example 1 - - - - 46.7 48.8 2.1 Comparative Example 2 include 5 ~ 7 - include 51.9 55.6 3.7 Comparative Example 3 - 5 ~ 7 include - 50.5 53.1 2.6 Comparative Example 4 - 5 ~ 7 - include 49.6 50.8 1.2 Comparative Example 5 include 2 to 4 - - 50.8 2.9

According to Table 2, the trapping performance of the trapping apparatus manufactured according to Example 1 including only the porous coral stone was the best, and the trapping apparatus of Comparative Example 1 in which nothing was inserted into the trapping apparatus was analyzed to have the lowest performance. In addition, the capturing performance of Comparative Example 3 including Ryukyu limestone having no porous structure was almost the same level as that of Comparative Example 1, and the pellet performance was low.

On the other hand, in Comparative Example 4, the pesticidal performance is very low, which can be judged to be due to the insecticidal performance of lavender. On the other hand, the captor of Comparative Example 2 showed insecticidal performance almost similar to that of Example 1, even though it contained lavender having insecticidal performance, and it was found that the coral stone is very effective in attracting the womb.

In addition, the captor of Comparative Example 5, which used a relatively small particle size of corals, had a significantly lower level of collapsing performance than the captor of Example 1, suggesting that the use of corundum granules at a level of 5 to 7 mm optimizes crawling performance Could know.
