The present invention relates to a small-package quantitative distribution and long-term sustained radial structure of natural enemies for control of agricultural pests and pest control method using the same, more specifically, for convenient quantitative radiation and continuous radiation of natural enemies, The present invention relates to a structure manufactured by placing a substitute feed and / or a filling material in a container, and a method of controlling pests by radiating natural enemies to crops using the same.

Until now, agricultural pest control in our country has relied mainly on chemical crop protection agents. However, due to excessive dependence on return-based chemical control methods, many side effects such as environmental pollution, damage to human beings, resistance to insect pests, major pests of latent pests, and weak competitiveness of crops are caused. In order to alleviate these side effects, the use of chemical crop protection agents is discouraged and a new agricultural pest control method is required.

In particular, in recent years, the social quality of safety and environmental protection for agricultural products and other foods is increasing due to the improvement of the quality of life of the people, and the competitiveness of domestic agricultural products due to the import of agricultural products is called for. There is also a need for a wise and effective way to deal with current issues such as the absence of effective pesticides against foreign pests, the emergence of resistant pests due to the abuse of chemical crop protection agents, and the deterioration of farmers' health. Natural pest control methods have been proposed as methods for controlling pests in agriculture that can best meet these demands. Natural enemies have not only coexisted with pests in natural ecosystems, but also have the advantage of being safe for useful organisms, including crops and humans, which can be useful for controlling pests.

In the case of the use of natural enemies for the control of agricultural pests, the mass packing method was adopted, and the user was required to distribute and use the secondary products in consideration of the characteristics of each natural product. This has been the main reason for the effective emission of natural enemies and the control of the generated pests due to poor distribution, the consumer's rejection due to the complexity and inconvenience in use. In addition, bulk packaging often results in the loss of value due to product deterioration during delivery.

In addition, some predatory mites, which are a kind of natural enemies, often fail to achieve the expected effect without the target pests when they are applied to crops for prevention. Therefore, it is necessary to prevent such a situation by mixing alternative foods when commercializing predatory mites.

In order to solve the above problems and to implement effective pest control using natural enemies, there is a demand for development of technologies related to quantitatively distributed radiation and continuous radiation of natural enemies.

In order to meet the above requirements, the present invention is to provide a structure for the quantitative distribution spinning and long-term sustained spinning of natural enemies made of a natural enemy, a substitute feed and / or filler material of the natural enemies in a box-shaped container. do.

It is another object of the present invention to provide a pest control method for controlling pests by radiating nemesis to crops using such a structure.

The present invention relates to a small-package quantitative distribution and long-term sustained radial structure of natural enemies for agricultural pest control and pest control method using the same, more specifically, for convenient quantitative radiation and continuous radiation of natural enemies, natural enemies, the natural enemies The present invention relates to a structure manufactured by placing a feed and / or filling material in a box-shaped container and a method of controlling pests by radiating natural enemies to crops using the same.

The present invention is characterized in that it is possible to quantitatively distribute to small packages to easily and effectively spin natural enemies, to maintain the best product condition for a long time and to increase the settling rate on crops. In addition, it has the advantage that it can produce safe agricultural products more easily and effectively because it reduces instability that can occur in the process of delivering natural enemies to consumers and improves user convenience.

The present invention aims to contribute to the quick production of safe agricultural products using eco-friendly farming methods and the convenience of consumer use, and to facilitate the faster conversion to eco-friendly farming methods, and furthermore, to ensure that safe farm products and natural enemies of the home country are commonly used throughout the world.

Existing products used for spinning natural enemies for agricultural pest control are mainly packaged products using plastic containers, which must be spun directly into crops or in other containers. At this time, there is a hassle to be distributed and applied according to the characteristics of each natural enemy, random distribution, misapplication of crops and adverse environment in the distribution and application process will reduce the control effect. In addition, when pests occur in the entire arable land, it is necessary to evenly distribute a certain amount of the natural enemy, but because the use and distribution work is inconvenient, the natural enemy is concentrated on the part of the arable land, so the control effect is lowered. In addition, in the case of predatory mites, it is necessary to use a substitute feed when used for prevention, if there is a shortage of extinction before achieving the purpose is difficult to expect effective control.

In order to solve the above problems, the inventors of the present invention provide quantitative distribution for each characteristic of natural enemies, improvement of user convenience, improvement of delivery and storage stability, improvement of aesthetics and robustness of products, supply of substitute foods and provision of artificial habitats. The present invention was completed by constructing a product structure capable of effective pest control through long-term persistence improvement.

The present invention improves the use and settlement of natural enemies for the purpose of controlling pests in agriculture, and improves the efficiency of pest control, and can be applied before the occurrence of pests on arable land, and the cost of controlling them can be reduced more easily and harmless to the living body. It has the advantage of being able to produce agricultural products.

Hereinafter, the present invention will be described in more detail.

The present invention provides a container including a spinneret and a small package quantitative spinning and long-lasting radial structure comprising a natural enemy contained in the container, a substitute feed of the natural enemy, and a filling material.

In the present invention, the nephew means a biological factor among environmental resistance that inhibits the growth of pests, and the parasitic nematodes, which are parasitic by laying eggs in the body of pests and predatory nemesis that eat insects, are classified according to their lifestyle. It includes all and includes both crawling and flying assaults as a classification according to the type of movement, and two or more different kinds may be included together.

An example of the parasitic nephew is Aphidius ervi ), Trichogramma evanescens ), Greenhouse pollen ( Encarsia formosa ), Aphids ( Aphidius) abdominalis ), Kolemanijindibul ( Aphidius colemani), hwangon jombeol (Eretmocerus There are eremicus), such as predatory as the slippery cheonjeokryu aekkot norinjae (Orius strigicollis), Switzerland Le Ski mites (Amblyseius swirskii ) Amblyseius cucumeris , Amblyseius californicus ), Orius laevigatus , Aphidoletes aphidimyza ), ladybug ( Harmonia axyridis ), Amblyseius barkeri ), Amblyseius womersleyi Evans ), Amblyseius fallacies , Phytoseiulus persimilis , Galendromus occidentalis), mites fishing hump Paris (Feltiella acarisuga), Erasmus moundou's (Erasmus Mundus ).

When the nemesis is classified according to the movement type, the crawling nemesis is classified as Amblyseius. swirskii ), Amblyseius cucumeris ), Amblyseius californicus ), Amblyseius barkeri ), Amblyseius womersleyi Evans ), Amblyseius fallacies , and Phytoseiulus persimilis ), Galendromus occidentalis ) are classified as crawling nemesis, and the bearded bee ( Aphidius) ervi ), Trichogramma evanescens , Encarsia formosa , Aphidius abdominalis , Aphidius colemani), hwangon jombeol (Eretmocerus eremicus) slippery aekkot norinjae (Orius strigicollis), the European aekkot norinjae (Orius laevigatus), aphids Gall Midge (Aphidoletes aphidimyza ), ladybug ( Harmonia axyridis ), Feltiella acarisuga), Erasmus moundou's (Erasmus Mundus ) is classified as a flying nephew.

Considering that parasitic nematodes can be hatched into larvae at the egg stage in the structure of the present invention, the parasitic nematodes included in the structure of the present invention can use all the life cycle stages from eggs to adult stage. In addition, the predatory nephew has a life history of eggs, larvae, nymphs, nymphs, adult stages, among which the stages to prey pests are all stages except the egg stage. Considering that the predatory nematodes can be hatched into larvae in the egg stage in the structure of the present invention, the predatory nematodes included in the structure of the present invention can use all the life cycle stages from eggs to adult stages.

The 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.

There is no restriction on the crop to which the structure of the present invention is applied, and it is applicable to all crops in which the pest is likely to occur.

In the present invention, when the predator is included as a natural enemy, it is necessary to add a replacement feed for the predatory natural enemy. The substitute food may be all nutrients, eggs, larvae, and adults that may be prey to predatory nemesis, preferably, Tetranychus urticae ), Tyrophagus putrescentiae and Sugar mite (Carpoglyphus lactis), and a group consisting of eggs of various moths such as Cadra cautella and Barley moth (Sitotroga cerealella). The amount of the replacement food is dependent on the number of predatory nemesis included in the structure, the desired duration, and the like. Generally, the ratio of natural prey to substitute food in the structure is 1: 5 to 1:40 based on the number of individuals. In addition, alternative food may include pollen, sugar, honey and the like.

When the parasitic nemesis is included as the nemesis, a material capable of absorbing the liquid, such as cotton, fiber pieces or the like, containing an aqueous sugar solution or honey water, may be included in the product to prepare for a feeding member that may occur during delivery.

In the case of food-borne nematodes or parasitic nemesis, additional fillings can be added that serve as artificial habitats by providing their spawning or hiding place. The filling material may be any material capable of serving as an artificial habitat such as, preferably, shells of grains such as sawdust, buckwheat, wheat bran, rice bran and rice bran, which are not toxic to insects, expanded vermiculite, dried moss, And it may be one or more selected from the group consisting of plant tissues and bark. The amount of the filling material used depends on the scattering characteristics of the natural enemies included in the structure and the compositional difference of the habitat environment, and generally, it is preferably in the range of 2 ml to 50 ml per structure. The filling material contains suitable moisture, thereby maintaining an appropriate humidity in the container, thereby providing an optimal scattering and habitat environment of natural enemies. In order to maintain the equatorial humidity, the water content of the filler is preferably 10% to 70% by volume.

In addition, the filling material may contain additional nutrients to provide food for larvae and adults fed as a substitute for parasitic nematodes or predatory nemesis. The nutritional substance may be water, sugar, and the like contained in the filling material. For the input of such nutritional substance, the filling material may be used by absorbing sugar and water-containing substances such as an aqueous sugar solution and honey water. In order to provide sufficient nutrition to parasitic nemesis or alternative feed, the content of sugar contained in the filling material is preferably 5% to 80% by volume.

The initial population of the nemesis included in the small package quantitative distribution and long-term sustained radiation 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, and the propagation power of the nemesis. . In the case of predatory nemesis, the initial population of the predatory nemesis included in the container is the total volume of the filling material in the structure, or the substitute food and the filling material, in consideration of securing sufficient populations and securing adequate space and food for their growth. It is good to make 2 to 150 based on 1ml. Parasitic nematodes vary in size from 20 to as many as 150, depending on their characteristics. The number of natural enemies included in the structure according to the present invention is determined in consideration of the moving distance of each natural enemy. 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 location of the structure application. When the structure is applied by calculating the total area and the number of natural enemies included, if the number of natural enemies contained in one structure is excessive, a large number of objects act in a certain range, but a space where natural enemies cannot function between neighboring structures. This may cause the pest control efficiency to decrease. 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.

In the structure of the present invention, the container containing the material that can be a substitute feed for natural enemies and artificial spawning and hiding place may be in the form of a polyhedron having five or more sides. The material of the container may be made of a material having a certain strength selected from the group consisting of various papers including natural pulp and recycled paper. The paper may be selected from the group consisting of general printing paper such as newspaper paper, white paper, heavy paper, and packaging paper including kraft paper. The thickness of the container of the present invention can be adjusted in various ways depending on the application form, and in general, it is preferable that it is 240g / ㎡ or more, more preferably, 240g / ㎡ to 450g / ㎡.

The container may be coated with a synthetic resin on the inner or outer surface. Synthetic resin used for such coating can be used as long as it can provide high humidity resistance and waterproofness to the coating layer. For example, polyethylene (PE), PP (polypropylene), polyester, PS (polystyrene), paraffin, etc. are used. can do. The coating solution including the synthetic resin may be applied by applying a surface of papers to be a container material, followed by heat treatment. In this way, by coating the inner or outer surface of the container with a synthetic resin, it is possible to maintain the moisture of the internal filling material, block the external poor environment, and increase the strength of the structure.

In the structure of the present invention, the thickness of the container used is not less than a predetermined range as described above, the appropriate moisture supply is made by the moisture contained in the filling material, it is easy to maintain the proper temperature and humidity in the container, the strength that can be protected from the external environment It has the advantage that it can have.

The container of the present invention is a container having a polygonal volume that includes a fixing ring that can be fixed to a crop, and can be manufactured in an adhesive or pulp mold manner and includes a spinneret. The pulp mold refers to a container made by compressing natural pulp into a special mold by dissolving it in a special solution, and in some cases, synthetic resin coating may be performed inside or outside.

The fixing ring for applying to the crop serves as a cover to prevent the external exposure and leakage of the product by blocking the spinneret until it is integrated with the main body or attached to the main body until it is delivered to the consumer from production. When used after delivery to the consumer, the part blocking the spinneret is separated from the main body to open the spinneret, and the separated part may be used as a fixing ring. The fixing means includes all means capable of fixing the container containing the predatory mite and the replacement food to the crop, for example, by opening the ring to insert the loop hole and the branch of the crop into the loop hole. A ring structure with a ring groove to enable it (see Fig. 2), or one end of which is a thread or wire structure fixed to the container and capable of being tied to the branches of the crop, or with one side of the container being held together It may be a tong-like structure (see FIG. 5), such as clampable clip or clip pin. In the case of a thread or wire structure, one end may be fixed to the container, the other end may be a structure that can be attached to the knot paper to further improve the adhesion when bound to the crop (see Fig. 4). The material of the ring is not limited, and may be made of synthetic resins including fibers, metals, plastic castings, etc., including the above-described paper, it is preferable to use the same material as the main body.

The container includes at least one spinneret on at least one surface except for the bottom of the main body for spinning the nemesis, the size is 0.5mm to 10mm, the number is suitable 1 to 5, the shape is limited none. The location of the spinneret is preferably located at least half above the container length in order to reduce the loss of individuals other than normal spinning when applied to the crop. In another embodiment, the structure of the present invention does not include a separate spinneret, by opening one side of the polyhedral container having five or more sides to serve as a spinneret of the natural flow. Such spinneret location and size may vary depending on the type of movement of the natural enemy. For example, in the case of a crawling nebula, the size of the spinneret does not matter much, whereas in the case of a flying nebula, the position of the spinneret is preferably relatively high, and most preferably, the upper side of the container is an open top. The larger the spinneret, the better.

In the present invention, the spinneret is manufactured and stored and transported in a closed state by means of easily detachable means, and is characterized in that it is easily detachable and used during use. As the spinneret is easily detachably closed in this manner, natural enemies are prevented from being lost during storage and transportation, and the environment inside the structure can be maintained under a certain condition, thereby enabling more effective pest control. The easily detachable spinneret closure method as described above is produced by discontinuously making the opening part so that the spinneret can be easily removed without covering the spinneret by the fixing ring as described above or completely opening the spinneret. How to do it.

Although the structure of the present invention is not particularly limited in size, it is advantageous to apply to crops having a width of 2 cm to 10 cm, a length of 0.5 cm to 10 cm, and a height of 2 cm to 20 cm.

[ Experimental Example ]

Experimental Example  One: Natural  Internal temperature of small package quantitative spinning and long-lasting radial structures, and Moisture retention  exam

The structure of the present invention was tested as follows to test whether the interior of the structure was suitable for creating a long-lasting environment in the interior of the greenhouse when applied to crops for predatory nematode radiation. Box-shaped structure for the small-package quantitative distribution and long-term continuous spinning produced in Example 2 (6cm × 2cm × 7cm in height, hereinafter referred to as "box-type structure") and the same as that produced in Example 2 The encapsulated structure (6 cm x 7 cm, hereinafter referred to as "encapsulated structure") was placed in a plastic greenhouse under the same conditions, and the temperature change and humidity change were observed and measured for 3 days, and the results are shown in FIG. 6. .

As shown in Figure 6, the two types of structures do not show a significant difference in temperature changes, but the difference between the maximum humidity and the minimum humidity in the mini-box according to the present invention in the humidity maintenance portion, a constant pattern is maintained for 3 days Maintaining proper temperature and humidity has been shown to provide a stable environment for the inhabitants of natural enemies, the biggest survival condition.

Experimental Example  2: duration test

The period of time that predatory nemesis can last in the structure was investigated. In the same manner as in Experimental Example 1, the box-shaped structure according to the present invention and the encapsulated structure as a comparative example were used, and the target crop was paprika at 6 weeks of sowing. The treatment was repeated six times. Irradiation was carried out to investigate the density of cucumber mites in each structure at weekly intervals. The results are shown in Table 1 below.

TABLE 1

Post Processing Period Average number of individuals in each structure Box structure Encapsulated Structure 1 parking 1948.0 1688.2 2 parking 4216.0 3943.0 3 parking 3048.3 2877.7 4 parking 1543.0 933.0 5 parking 524.6 358.0 6 parking 379.6 267.7

As shown in Table 1, the average population of the box-shaped structure was kept high for 6 weeks compared to the encapsulated structure, which shows that it is possible to steadily discharge cucumber cucumber mites of higher density than the existing structure after applying to crops. . In view of the results obtained in Examples 3 and 4 above, maintaining a constant temperature and humidity maintains the feeding mite in the structure at a certain density, which is a driving force for maintaining a high population of cucumber mites for a long time. The settlement effect can also be expected.

Experimental Example  3: predation Natural  Loss population test after delivery

In the box-like structure and the existing encapsulated structure according to the present invention, a test was carried out on the population of predatory natural enemies that escaped and disappeared out of product packaging during delivery. In the box-type container and the conventional paper bag-type container produced in Example 1, about 1000 cucumbers and 5000 long-feeding mites each were replaced with wheat bran, and 10 each of the sealed structures were manufactured, for a total of 20 pieces. The structure was placed in a square transparent plastic container, and the number of individuals escaping after 24 hours, which is an average delivery period after shipping, was measured, and the results are shown in Table 2 below.

TABLE 2

Structure Number of escapes after 24 hours for each structure (Marine) Box structure Encapsulated Structure One 42 118 2 56 204 3 88 92 4 69 146 5 48 128 6 57 161 7 109 137 8 49 152 9 60 89 10 86 143 Average escape population 66.4 137.0

As shown in Table 2, the box-shaped structure according to the present invention was found to be less than the number of individuals lost to escape compared to the conventional encapsulated structure. In the case of the existing encapsulated structure, the predatory nemesis in the structure is delivered to the consumer without covering or blocking the hole in the hole, and it is lost because the predatory nemesis in the structure escapes and disappears. However, by using the above structure, the loss rate is reduced from the producer's point of view to increase the production efficiency and consumers can use a better product.

Experimental Example  4: Flight Natural  Fable Population Test

In the box-shaped container and the existing plastic bottle produced in Example 1, each abyssin dival (cycles in the order of eggs, larvae, nachos chrysalis, and adults, and takes 14 days at 20 ℃ ~ 25 ℃ from eggs to adults) About 100 animals were packed and sealed to prepare three box-type structures and three bottle-type structures. Each of these was placed in a square transparent plastic container, and the average value of the number of flocked individuals from 24 hours after the average delivery period after product shipment was measured and shown in Table 3.

TABLE 3

Average allegory population (mari) Box structure Bottle type structure 1 day later 18 16 2 days later 24 24 5 days later 54 40 Sum 96 80

As can be seen in Table 3, the average allegorical population in the box-shaped structure according to the present invention was found to be larger than the existing bottle-type structure. In addition, the existing bottle-type structure is packaged in a low temperature place and shipped at room temperature, condensation occurs inside the bottle, the wing and body of the abyssin beta clings to the wall of the bottle, so that it does not fly completely, so it does not radiate to the field. there was. However, in the case of the box-shaped structure according to the present invention, the inside of the box can absorb condensation that may occur after shipment, thereby satisfying better flight conditions for flying natural enemies such as abyss.
