[Private Technology]

So far, pest control in Korea has been mainly dependent on chemical crop protection agents. However, this caused many side effects such as side effects due to environmental pollution, damage to livestock, resistance to pests, major pests of latent pests, and weakened competitiveness of crops. Therefore, the use of chemical crop protection agents is avoided, and thus new pest control methods have been required.

Parasitic nemesis parasites in the body of pests, controlling pests. For example, colemanijin dives control parasitic bodies in the body of aphids, and oyster fly bees parasitic outside the body of oysters and control them. It is a natural enemy that has high utility, such as killing pests through host feeding.

In particular, in recent years, the social concern for the safety and environmental protection of agricultural products and other foods due to the improvement of the quality of people's living, the competitiveness of domestically produced agricultural products due to the import of agricultural products, the absence of effective pesticides against foreign pests, chemical crop protection agents There is a need for a control method that can respond wisely and effectively to the emergence of resistant pests and the deterioration of farmers' health due to abuse. As a control method that best meets these demands, a natural enemy control method has emerged. In particular, parasitic nemesis has not only coexisted as a prey for insects in natural ecosystems, but also can be used safely for crops and humans and useful organisms. There is an advantage.

The use of these parasitic nemesis as a means of biological control requires the mass breeding and commercialization of them. Among them, the existing products for greenhouse dust and yellow-hot zombie spinning have one attachment hole to which the chrysalis of chrysalis are attached, and the loss of natural enemies is very large due to the high rate of fabled adults attaching to the attachment surface of the attachment holes. There was a drawback in that it took a lot of time and effort to apply each of the crops to a large number of cards. Therefore, there is a need for the development of a natural spinning structure of natural enemies low natural loss rate, easy to apply crops.

The present invention is to solve the above problems, low loss ratio of natural enemies, and easy to apply the crops to the development of continuous spinning structure of natural enemies completed the present invention.

It is therefore an object of the present invention to provide a card-like structure for spun-rays, characterized in that it has two or more attachment parts to which the natural mummies are attached.

It is still another object of the present invention to provide a pest control method using the above structure for carding for spontaneous spinning.

The present invention relates to a card-like structure for continuous spinning of natural enemies for pest control, and a pest control method using the same. Cardit structure for continuous spinning of natural enemies of the present invention has two or more attachment parts to which the natural enemy mummies are attached, thereby improving the anchorage and long-term persistence of natural enemies can be obtained more excellent pest control effect, can be safely applied to plants That has the advantage.

As interest in the use of environmentally safe natural enemies for pest control is increasing, the development of products using natural enemies as biological pesticides has become active, and natural natural spinning structures capable of controlling pests by emitting natural enemies when applying crops Is being developed. The natural spinning structure may be classified into a bottle type, an encapsulated type, a box type, and a card type according to a shape. Among them, the card-like structure forms an attachment hole in the card and installs an attachment means inside the attachment hole to attach the mummies of natural enemies and apply them to crops, so that the natural enemies of the mummies can control pests present in the crop. As a product to be used, it takes up little space and has the advantage of easy production and application of crops.

However, as described above, the existing card-like structure has only one attachment hole to which natural mummies are attached, so that a relatively wide attachment surface is formed to provide a sufficient attachment surface for attaching the necessary number of mums for pest control. Because it should be, the adult nature of the allegory of natural enemies from the mother does not escape from the attachment surface is attached to the attachment surface is high death rate, there was a problem that the number of natural enemies that can not be used for actual pest control and lost. In addition, if the size of the attachment hole is reduced, the number of attachable mummies is reduced, so that a relatively large number of cards are required to control pests of the same cultivation area or crop population. The problem arises.

The present invention has been made to solve such a problem, by increasing the number of natural attachment portion of the natural enemy of the card-like structure for natural emissive spinning, by reducing the area of the attachment surface that is more likely to be attached to the adult, Reduces the loss of natural enemies, improves the attachment of the structure to crops by improving the orientation of the hooks on the crop, makes it easier for the adult to move to the site of the pest, and for long-lasting spontaneous spinning The card-like structure was developed and completed.

Accordingly, the present invention provides two or more attachment portions for attachment of the chrysalis of the natural enemy; Chrysalis chrysalis of nemesis attached to the attachment portion; And a fixing means fixable to the crop, the card-like structure for continuous spinning of natural enemies.

The natural nebula attached to the card-like structure of the present invention refers to a biological factor among environmental resistance that suppresses the growth of pests, and according to the lifestyle, it lays eggs in the body of predatory nemesis and pests that eat insects. Includes all parasitic parasitic nemesis, and two or more different species may be included together.

Examples of the parasitic nemesis include Aphidius ervi , Trichogramma evanescens , Encarsia formosa , Aphelinus abdominalis , Aphelinus abdominalis , Aphidius colemani There are (Eretmocerus eremicus), such as predatory cheonjeokryu as the chief aekkot norinjae (Orius strigicollis), Mediterranean Come mites (Amblyseius swirskii), cucumbers come mites (Amblyseius cucumeris) desert Come mites (Amblyseius californicus), slippery aekkot norinjae (Orius laevigatus ), aphids Gall Midge (Aphidoletes aphidimyza), ladybug (Harmonia axyridis), trumpets come mites (Amblyseius barkeri), ginteol come mites (Amblyseius womersleyi Evans), Palazzo systems come mites (Amblyseius fallacies), Chile come mites (Phytoseiulus persimilis) , the Western wolves, etc. mites (Galendromus occidentalis), mites fishing hump Paris (Feltiella acarisuga), seventh bit moundou's Russ Moses (Eretmocerus mundus).

The card-like structure of the present invention has a control effect against various pests according to the included natural enemies, for example, aphids; Flower Yellow Lancera Beetle, Taiwan Lancera Beetle; Thrips, including cucumber thrips; Dietary mites, including spotted mites, chaff mites, dust mites, and the like; And tobacco powder, greenhouse powder, powdered powder containing strawberry powder, thief moth, Chinese cabbage moth, moths including extinct moths, and the like.

In a preferred embodiment of the present invention, the nemesis may be a parasitic nemesis, such as greenhouse pollen zombie ( Encarsia formosa ) and yellow- hot zombie ( Eretmocerus eremicus ). The life cycle of Encarsia formosa , a temporary example of the present invention, is a stage of eggs, larvae, pupa and adult, while parasitic in the body of greenhouse powder and tobacco powder nymphs generated in crops and eggs of greenhouse powder and tobacco powder. They eat or kill parasites in their bodies. Encarsia formosa ( Encarsia formosa ) used in the examples of the present invention is a species licensed for biological control under the National Plant Quarantine Notice No. 2003-9.

The number of mummies attached to the card-like structure of the present invention can be appropriately adjusted in consideration of the type and distribution of pests present in the arable land and crops to be applied, the type and the propagation force of natural enemies, for example, a total of 20 to 150 It can be made into pieces, and it can attach to each attachment part suitably. The number of mummies is determined in consideration of the moving distance of natural enemies. Given that there is a limit to the area the natural object can move, the natural area of action is limited to a certain range around the structure position. When the structure is actually applied to an appropriate number by calculating the total arable land area and the number of natural enemies contained, if the number of natural enemies contained in one structure is excessive, the excess number of objects acts in a certain range while This can create a space where natural enemies cannot act, which can reduce pest control efficiency. The structure of the present invention is applied to a small package to contain an appropriate number of natural enemies, thereby solving this problem, and has the advantage that quantitatively distributed spinning is possible.

The attachment portion formed in the card-like structure of the present invention is a portion to which the chrysalis of natural enemies are safely stored and transported and applied to the crop chair to be secured to adulthood, and all forms for attachment of the mummy are possible. For example, the attachment portion is formed in a hole in the card, the adhesive tape is attached to one side of the hole, the mumminess is attached to the adhesive side of the adhesive tape exposed to the hole, or simply a suitable area on one side of the card It may be in the form of an adhesive surface is coated with an adhesive or a double-sided adhesive tape is attached to the mummies.

As described above, in the present invention, since two or more attachment portions, for example, attachment holes or attachment surfaces are formed, the number of mummies to be attached to each attachment portion is reduced, so that each formed to attach the same number of mummys. Since the adhesion area of R is relatively small, the number of individuals attached to the attachment portion and lost is significantly reduced.

Further, in another embodiment of the present invention, the portion in which the attachment portion is formed is thinner than other card portions, such that the mummies attached to the attachment portion in contact with the neighboring card when the card is stacked or stored several times. It may have a structure that can be prevented from being pressed or lost by (see FIG. 2).

In the card-like structure of the present invention, the number of mummies attached portion may be appropriately determined in consideration of the number of mummies to be attached, the moving distance of the adult, and the like, and two or more, preferably two to five, more preferably Preferably three to four. The area of the attachment part is determined in consideration of the number of attachments, the number of attachment parts, and the like, and may have a diameter of 1 mm to 5 mm, preferably 3 mm to 5 mm. This is because the diameter of the attachment portion of the existing structure is more than 6 mm was improved to a large number of adults lost to be attached to it. The number and area of the attachment portion are appropriately adjusted in consideration of the number of mummies to be attached. In addition, the position of the attachment portion is not limited in any way, it can be located in a row in the horizontal or longitudinal direction, or in parallel, it may be located in a polygonal form, such as a circle, triangle, square, rhombus.

The paper that can be used as a card material of the present invention includes a general paper such as newspaper paper, white paper, heavy paper and packaging paper including kraft paper, the fibers are not limited, it is best to use a nonwoven fabric. In addition, the card of the present invention may be coated on one or both sides with a synthetic resin, the synthetic resin can be used as long as it can impart high humidity resistance and waterproofness to the coating layer, for example, PE (polyethylene), Polypropylene (PP), Polyester, PS (Polystyren), paraffin, etc. can be used.

The shape of the card-like structure of the present invention is not limited, and may be a polygon such as a circle, a rectangle, or a square. The size of the card-like structure of the present invention is also not particularly limited, in the case of a circular may be 5 to 15 cm in diameter, in the case of a square is 2 cm to 15 cm, 3 cm to 20 cm long because it is appropriately applied to crops May be advantageous.

The card-like structure of the present invention may further comprise suitable fastening means for easy application to crops. The fixing means includes all means capable of fixing the structure to the crop, for example, may be integrally present in the card in which the attachment portion of the mummy is located, or may be additionally attached to the loop, thread, and the like.

In the case where the fixing means is integrally present in the card, a portion of the card may be attached to the mummies, and holes may be formed in other parts of the card, and holes may be formed to easily insert the crop into the holes. It may be to include a groove to be opened. The hole is appropriately adjustable according to the thickness of the crop to be applied, and may be usually 0.5 cm or more, preferably 0.5 to 15 cm, more preferably 1 to 10 cm. In addition, the groove is to open the hole by cutting the side of the hole so that the branch of the crop can be easily inserted into the hole located inside the card, the groove was formed in a straight line in the past, preferred embodiment of the present invention In the example, the outer ends (opposite ends of the hole-side end) of the grooves may be diagonally formed to face upwards, so that they may be easily fitted to the crop and may not be easily removed.

In addition, the groove for applying the crop of most existing card-like structure is directed to the right, it is difficult to work with the right hand when applied to the crop had a disadvantage of poor workability, in the present invention the groove is directed to the left The advantage is that it can be easily inserted into the crop with the right hand. This is a very beneficial effect considering the reality of Korea, which is mostly right-handed.

In another embodiment, the fixing means can be fixed by attaching a thread to the top of the card to bind to the crop, or a knot paper is attached to the opposite end of the card attaching part of the thread to form a knot when tying it to the crop.
