Description

  The present invention relates to a device for enhancing the establishment of natural enemy organisms, and further assisting the movement of natural enemy organisms between strains of cultivated plants such as crops and horticultural plants, and a method for increasing the dispersion of natural enemy organisms using this device. .

  In recent years, for example, as shown in Patent Documents 1 to 3, biological pesticides that release predatory natural enemy organisms that prey on harmful pests have been used for crops such as eggplants and horticultural plants such as verbena. These predatory natural enemies are of the type that does not fly like the ticks, and the type that cannot fly at the time of larvae, such as stink bugs and ladybirds, and can fly when it becomes an adult Exists.

  Predatory natural enemy organisms must be released to farms, fields, gardens, plastic houses, etc. as biological pesticides in the early days when the number of pests is low. However, since there are few pests that feed, there is a risk that flying predatory natural enemies can easily fly and move to other places. Even when predatory natural enemies that do not fly or predatory natural enemies that can fly when they become adults are released in the state of larvae, they may move to other places by walking. For this reason, predatory natural enemy organisms, as they are, have a poor adult colonization rate in farms, fields, gardens, greenhouses, etc., and therefore measures to obtain sufficient effects as biological pesticides are required.

  Therefore, in order to increase the prevalence of predatory natural enemies in farms, fields, gardens, and greenhouses even in the early stages of pests, substitute feeds such as frozen eggs, Artemia (brine) A method of preventing movement by spraying durable shrimp eggs, cattail pollen, etc. on the leaves of agricultural crops or horticultural plants and feeding them. Moreover, in order to increase the colonization rate of the predatory natural enemy organism in the adult stage, for example, as shown in Patent Documents 2 and 3, a method of releasing a ladybird that does not have a flying ability even if it becomes an adult is developed. .

  However, some of the leaves of agricultural crops and horticultural plants have narrow widths, and some have their distal ends extending upward or downward from the horizontal relative to the base end. Even if a substitute bait is sprayed on such leaves, it will fall to the ground and may not be sufficiently supplied as a bait to increase the rate of establishment of predatory natural enemies. Furthermore, since it is cumbersome to spray substitute food one by one for crops and horticultural plants, it is not widely used in practice.

  Moreover, in order to allow predatory natural enemy organisms to function as biological pesticides throughout farms, fields, gardens, greenhouses, etc., it is preferable to release them uniformly in small amounts to all the crops and horticultural plants. Actually difficult. For this reason, it is a reality that the predetermined number is released and the animals are released together to some extent. When the crops and horticultural plants are separated from each other, the adjacent crops and horticultural leaves are not adjacent to each other, and the predatory natural enemy organisms travel along the overlapping parts of the leaves and other plants. Cannot move to plant.

  In this case, as shown in Patent Documents 2 and 3, if the flying ability of predatory natural enemy organisms is lost, it is necessary to descend from the crops and horticultural plants to the ground. It becomes difficult to move to the next crop or horticultural plant. For this reason, predatory natural enemy organisms cannot be dispersed from farmed or horticultural plant strains released to other crops or horticultural plant strains, and are sufficient as biological pesticides in farms, fields, gardens, and greenhouses as a whole. A malfunction that does not function properly is considered. This defect is also conceivable in the same way for non-flying predatory natural enemy organisms such as larvae and turnip mites of flying predatory natural enemy organisms.

  Accordingly, the present invention provides a predatory natural enemy organism even in the early stage of occurrence with a small number of pests that become food by stably feeding a substitute feed regardless of the state of leaves such as crops or horticultural plants. In addition, it is possible to increase the retention rate, and even when using predatory natural enemy organisms that do not have the ability to fly as biological pesticides, it can be used for other crops such as released farm products or horticultural plants. It is an object of the present invention to provide an auxiliary instrument for promoting the establishment and movement of natural enemy organisms, which can disperse cultivated plants into strains, and a method for dispersing natural enemy organisms using the same.

  The assisting instrument for promoting and moving natural enemy organisms according to the invention of claim 1 is the auxiliary instrument for promoting and moving natural enemy organisms that can be bridged between strains of a plurality of cultivated plants so that the natural enemy organisms can move along the outer surface. It is an auxiliary device for promotion, and can improve the fixation of natural enemy organisms by being composed of a string-like member and a natural enemy food material attached to the outer surface of the string-like member by an adhesive. Features.

  Natural enemy organisms are insects such as predatory stink bugs and ladybirds that have lost flight ability even in their larvae and adult stages, and are organisms such as red mites that have flight ability from the beginning. Not applicable. Examples of cultivated plants include a wide variety of agricultural products such as cucumber, eggplant, and tomato, and horticultural plants such as verbena, carnation, and rose.

This makes it possible to feed natural enemy organisms with the food material attached to the outer surface of the auxiliary device for promoting fixation and movement, so that natural enemy organisms can be detected even in the initial stage where there are few occurrences of pests to be preyed on by natural enemy organisms. Increases the rate of establishment in the place of release. By laying the auxiliary equipment for promoting fixation and movement promoting the food material on a plurality of cultivated plants, it is possible to obtain the same effect as arranging the food material for each cultivated plant.
In addition, natural enemy organisms released to a certain crop or horticultural plant stock are transmitted to auxiliary farming or horticultural plant stocks through the auxiliary equipment for promoting settlement and migration, It moves along the string-like member of the auxiliary device for promoting movement. In addition, since the food material is attached to the outer surface of the string-like member of the auxiliary device for promoting fixation and movement, the movement rate of natural enemy organisms is increased by being attracted by the food material.

  An auxiliary instrument for promoting the fixation and movement of natural enemy organisms according to the invention of claim 2 is characterized by having a cylindrical member attached to the outer periphery of the string-like member. A gap is formed between the cylindrical members attached to the string-like member, and the food material attached to the string-like member and the string-like member is exposed from the gap between the cylindrical members (invention). Item 3). An inner diameter of the tubular member is larger than an outer diameter of the string-like member so that a gap is formed between the tubular member. The material of the cylindrical member is, for example, a synthetic resin such as polyethylene terephthalate or paper. For example, the cylindrical member may have an elliptical shape or an oval shape when viewed from the axial direction so that the string-shaped member does not rotate about the axis.

  As a result, certain species of natural enemy creatures enter the gap between the tubular member and the string member from between the tubular member and the tubular member, so that the inside of the tubular member is a hidden place, The retention rate of natural enemy creatures further increases. Moreover, the food which adhered to the string-like member and the string-like member from water, rainwater, and dew condensation which are sprinkled for cultivation by forming the cylindrical member with a material having excellent water resistance such as plastic or applying water-resistant processing It becomes possible to protect the material. Furthermore, when spraying agricultural chemicals on cultivated plant strains, it is possible to reduce the risk of exposure to natural enemy organisms.

  A method for dispersing natural enemy organisms according to the invention of claim 5 is a method for dispersing natural enemy organisms using the auxiliary instrument for promoting the establishment and movement of natural enemy organisms according to any one of claims 1 to 4, The step of releasing natural enemy organisms to one or two or more cultivated plant strains arbitrarily selected from a plurality of cultivated plant strains, and at least the plurality of string-like members to which a food material is added with an adhesive Between one or more cultivated plant strains of which the natural enemy organisms have been released and one or more cultivated plant strains that have not been released. And a process.

  As a result, it becomes possible to feed natural enemy organisms with the food material attached to the outer surface of the auxiliary device for promoting fixation and movement, so that the food material can be used even at the initial stage when there are few pests to be preyed on by natural enemy organisms. Since natural enemy organisms eat, it is possible to increase the rate of establishment in places where natural enemy organisms are released. Then, natural enemies released in a certain crop or horticultural plant stock are transmitted to auxiliary farming or horticultural plant strains through the auxiliary equipment for promoting settlement and migration, and the establishment of It can be moved along the string-like member of the auxiliary device for promoting movement. Moreover, by attaching the food material to the outer surface of the string-like member of the auxiliary device for promoting fixation / movement promotion, natural enemy organisms are attracted to the food material, so that the movement rate of the natural enemy organisms can be increased.

As described above, according to the inventions according to claims 1 to 5, it becomes possible to feed natural enemy organisms with the food material attached to the outer surface of the auxiliary device for promoting fixation and movement, Even in the initial stage where there are few pests to be preyed on by natural enemy organisms, the natural enemy organisms eat the food, so that the rate of establishment in the place where natural enemy organisms are released can be increased.
By laying the auxiliary equipment for promoting fixation and movement promoting the food material on a plurality of cultivated plants, it is possible to obtain the same effect as arranging the food material for each cultivated plant.
Since food materials are secured from the beginning, natural enemies are expected to breed by feeding them, so the number of natural enemies to be released first is less than when no food materials are supplied. It is possible to reduce the number of cells, and the proliferation is performed quickly.
In addition, the natural enemy organisms released in a certain crop or horticultural plant strain are transferred to the adjacent crop or horticultural plant strain through the string member of the auxiliary device for promoting fixation and movement that is spread between the strains. Can be moved.
In addition, by attaching the food material to the outer surface of the string-like member of the auxiliary device for promoting fixation / movement promotion, natural enemy organisms are attracted by the food material, so that the movement rate of the natural enemy organisms can be increased.
Therefore, even natural enemies with no flying ability can be diffused to farms, fields, gardens, greenhouses, and the like, and can be effectively used as biological pesticides.

In particular, according to the inventions according to claims 2 to 5, a certain kind of natural creatures of the cylindrical member is formed between the cylindrical member and the cylindrical member between the cylindrical member and the string member. Since it enters the gap and makes the inside of the cylindrical member a hidden place, it is possible to further increase the fixation rate of natural enemy creatures.
In addition, by forming the cylindrical member with a material excellent in water resistance such as plastic or applying water-resistant processing, the food material attached to the string-like member or string-like member from water, rainwater, or condensation that is spread for cultivation Can be protected.
Furthermore, when spraying agricultural chemicals on cultivated plant strains, it is possible to reduce the risk of exposure to natural enemy organisms.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  As shown in FIG. 1, an auxiliary instrument for promoting fixation / movement promotion of natural enemy organisms (hereinafter referred to as an auxiliary instrument for promoting fixation / movement promotion) 1 of the present invention includes a string-like member 2 and a string-like member 2. It is composed of at least the attached food material 3.

  The string-like member 2 is, for example, a hemp string as shown in FIGS. 2 (a) and 2 (b), wool as shown in FIGS. 3 (a) and 3 (b) and FIGS. 4 (a) and 4 (b). And the like, a felt string as shown in FIGS. 5 (a) and 5 (b), a vinyl string (not shown), and the like. When hemp string or yarn string is used as the string-like member 2, it can be easily decomposed in the soil, so that it can be swallowed into the soil together with the plant residue after plant cultivation. . Moreover, when the material which does not have water absorption properties, such as a vinyl string, is used as the string-like member 2, it does not corrode even when sprayed with water or rain water, and can be used for a long time. The total length of the string-like member 2 is, for example, from 2 to 3 m to 10 m, and is properly used depending on various conditions such as the type of cultivated plant, the place where natural enemy organisms such as farms, fields, gardens, and greenhouses are released.

  The food material 3 is referred to as a substitute food that is provided in place of the pests that prey on natural enemies, and for predatory insects, for example, FIG. 2 (b), FIG. 3 (b), and FIG. Artemia (brine shrimp) durable eggs as shown in (b) are used. Although not shown in the figure, eggs of the white scallop that have been processed so as not to hatch (for example, frozen processing etc.) are also used. For predatory mites, for example, catfish pollen as shown in FIG. 4 (b) or pine pollen (not shown) is used. In addition, it is not particularly limited as long as natural enemies to be released can feed, such as artificial feed processed into powder. Further, a mixture of two or more kinds such as a mixed egg of a white-spotted snail that has been treated so as not to hatch (such as a freezing treatment) and a durable egg of Artemia may be used.

  The adhesive for adhering the dietary material 3 to the string-like member 2 is not illustrated due to its nature. For example, starch-based adhesives, acrylic resin-based adhesives, rubber-based adhesives, rosin, glue, etc. A variety of things are used. In places where there is a risk of splashing water or rainwater, it is preferable to use a water-insoluble adhesive such as rubber.

  Next, an example of the manufacturing process of the fixing / promoting auxiliary instrument 1 and the arrangement in a farm, a field, a garden, a greenhouse, etc. will be described.

  The manufacturing process of the fixing / promoting auxiliary device 1 is performed by, for example, immersing the string-like member 2 in an adhesive and passing the string-like member 2 through the food material 3 before the adhesive dries. This is done by attaching the food material 3 to the outer surface of 2. In such a manufacturing process, it is suitable for the full length of the string-like member 2 to be 2-3 m, for example.

  The arrangement of the auxiliary device 1 for promoting fixation / promotion is because, when the plant P for cultivation is an agricultural crop, the plants P for the plant P are lined up along a row of straws such as fields and plastic greenhouses. For example, as shown in FIG. 6 to FIG. 8, the leaves and stems of the respective strains are spread and passed between the strains as necessary. The interval between each strain of the plant P for cultivation is, for example, 45 cm. For this reason, also in the experiment shown below, the space | interval of each strain | stump | stock of the plant P for cultivation is set to 45 cm.

  The arrangement of the auxiliary device 1 for promoting fixation / movement promotion varies depending on the way the leaf of the cultivation plant P is attached, the shape thereof, the height of the cultivation plant, and the like. FIG. 6 is an arrangement example of the auxiliary instrument 1 for promoting and promoting the fixation when the plant P for cultivation is cucumber, and FIG. 7 is the auxiliary instrument 1 for promoting and promoting the fixation when the plant P for cultivation is eggplant. FIG. 8 is an arrangement example of the auxiliary instrument 1 for promoting fixation and promoting movement when the plant P for cultivation is a tomato.

In the case of using the auxiliary device 1 for promoting fixation / movement promotion manufactured in the above-described process, the increase in natural enemy creature fixing rate is shown in comparison with the case where the auxiliary device 1 for promoting fixation / movement promotion is not used. A description will be made based on eight experimental results shown in FIGS. In each experiment, on the one hand, two strains of the plant P for cultivation are placed in a 15 m ² greenhouse, and the auxiliary device 1 for promoting fixation and movement is bridged between the two strains of the plant P for cultivation. In total, 10 natural enemies were released between the two strains. On the other hand, two strains of the cultivation plant P were placed in a 15 m ² plastic house, and the establishment of the two cultivation plants P was promoted.・ A total of 10 natural enemies were released in two stocks without the movement-promoting auxiliary device 1 being installed, and observation was performed to count the number of natural enemy organisms in each stock every week. This is an average of several experiments.

  FIG. 9 shows experimental results when tobacco turtle (a kind of stink bug) was released in cucumber. One week after the start date of the experiment (when there is no auxiliary device 1 for promoting and / or moving promotion) between the two strains of the plant P for cultivation (when there is no auxiliary device 1 for promoting and / or moving and promoting) 16/7/24) The number of tobacco turtles is already zero. One week after the start date of the experiment (when there is an auxiliary instrument 1 for the promotion of migration and movement promotion) when the auxiliary instrument 1 for the promotion of migration and fixation is spread between two strains of the plant P for cultivation In '16 / 7/24), the number of tobacco turtles decreased from 10 to 2, but in the measurement of observation days every week thereafter ('16 / 7/31, '16 / 8/1)) The number of individuals will never be zero.

  FIG. 10 shows the experimental results when tobacco turtles were released on tomatoes. In the case of the absence of the auxiliary device 1 for promoting fixation / movement, the number of tobacco turtles is already zero one week after the experiment start date ('16 / 7/1). In the case where there is an auxiliary device 1 for promoting fixation and movement, the number of cigarette turtles decreases from 10 after one week ('16 / 7/1) from the start of the experiment, but every week thereafter (' 16/7/8, '16 / 7/15) In the measurement when observed, the number of individuals changed between 4 and 6.

  FIG. 11 shows the experimental results when tobacco turtles were released from eggplants. In the case of the absence of the auxiliary device 1 for promoting fixation and movement, the number of tobacco turtles is zero after two weeks ('16 / 6/17) from the start of the experiment. In the case where there is an auxiliary instrument 1 for promoting fixation and movement, the number of individuals is 2 or more in the measurement 2 weeks after the experiment start date ('16 / 6/17), and 3 weeks later ( '16 / 6/24), on the contrary, the number of individuals increased.

  FIG. 12 shows the experimental results when tobacco turtles were released in verbena. One week after the start of the experiment ('16 / 6/3), 2 weeks, when the case without the auxiliary device 1 for fixing / moving promotion is compared with the case with the auxiliary device 1 for fixing / moving promotion After ('16 / 6/10) and after 3 weeks ('16 / 6/17), when there is an auxiliary instrument 1 for promoting fixation / movement promotion, an auxiliary instrument 1 for promoting fixation / movement promotion The number of individuals measured on the observation day is larger than the case of none.

  FIG. 13 shows the experimental results when the black gourd turtle (a kind of stink bug) was released in cucumber. In the case where the auxiliary device 1 for promoting settlement / movement promotion is not laid between two strains (without the auxiliary device 1 for promoting fixation / movement promotion), two weeks after the experiment start date ('16 / 7/31 ), The number of black gourd turtles is zero. In the case where an auxiliary device 1 for promoting fixation / movement promotion is placed between two strains (when the auxiliary device 1 for fixing / moving promotion is present), one week after the experiment start date ('16 / 7/24 ), The number of black gourd turtles decreases from 10 to less than 2 but the number measured after 2 weeks ('16 / 7/31) and 3 weeks ('16 / 8/7) is 0. There is no head.

  FIG. 14 shows the experimental results when the black gourd turtle was released on the tomato. One week after the start of the experiment ('16 / 7/1), 2 weeks, when the case without the auxiliary device 1 for promoting fixation / movement promotion is compared with the case with the auxiliary device 1 for promoting fixation / movement promotion After ('16 / 7/8) and after about 3 weeks ('16 / 7/18), in the case of using the auxiliary device 1 for promoting fixation / moving promotion, fixing / moving promotion is better. The measured number of individuals is larger than in the case without the auxiliary device 1 for use.

  FIG. 15 shows the results of an experiment in which black leopard tongue turtles were released from eggplants. In the case without the anchorage promotion / movement promotion auxiliary device 1, the population of black gourd turtles is already zero two weeks after the experiment start date ('16 / 6/10). In the case where there is an auxiliary device 1 for promoting fixation and movement, the number of individuals is 4 or more in the measurement 2 weeks after the experiment start date ('16 / 6/17), and 3 weeks later ( '16 / 6/24), on the contrary, the number of individuals measured increased.

  FIG. 16 shows the experimental results when the black gourd turtle is released in verbena. In the case without the auxiliary device 1 for fixing / moving promotion, one week after the experiment start date ('16 / 6/3), two weeks later ('16 / 6/10), three weeks later ('16 / 6/17), the measured number of black gourd turtle turtles has decreased for a while. In the case of using the auxiliary device 1 for fixing / promoting fixation, the fixing is performed in any measurement after one week ('16 / 6/3) and two weeks ('16 / 6/10) from the start date of the experiment. More individuals were measured than without the aid / promotion aid 1 and moreover, after 3 weeks ('16 / 6/17) than after 2 weeks ('16 / 6/10) The number of individuals measured has also increased.

  From these experimental results, even when various patterns of experiments are performed, the case of using the fixing promotion / movement promotion auxiliary device 1 is more than the case of not using the fixing promotion / movement promotion auxiliary device 1. It can be seen that natural enemy creatures are highly established.

  As a result of experiments on the movement rate of natural enemy organisms from one cultivated plant to another cultivated plant, in the case where the auxiliary device 1 for promoting fixation / movement promotion is installed (when there is an auxiliary device 1 for promoting fixation / movement promotion) FIG. 17 and FIG. 18 explain that the movement rate is higher than when the auxiliary device 1 for promoting fixation / movement promotion is not laid over (without the auxiliary device 1 for fixing / moving promotion). To do. Since natural enemy organisms used in this experiment need to be unable to fly, larvae of tobacco turtles are used in FIG. 17, and larvae of Nami Tentou are used in FIG. In this experiment, 10 natural enemies were released in one of the two cultivated plant strains, and how much moved from one released strain to the other one week after the release date. These experiments were performed several times and averaged.

  FIG. 17 shows the experimental results when tobacco turtle larvae were released in eggplant. When there is no auxiliary device 1 for promoting fixation and movement between the two strains of eggplant and when there is an auxiliary device 1 for promoting fixation and movement, and when there is no auxiliary device 1 for promoting fixation and movement In contrast, the movement rate is 0%, while in the case of the fixing promotion / movement promotion auxiliary device 1, the movement rate is between 12% and 13%.

  FIG. 18 shows the experimental results when the larvae of Nami Tentou were released in verbena. When there is no auxiliary device 1 for promoting and moving between the two strains of verbena, and when there is no auxiliary device 1 for promoting and moving, and when there is no auxiliary device 1 for promoting and moving In contrast, the movement rate is 0%, while in the case of the fixing promotion / movement promotion auxiliary device 1, the movement rate is between 10% and 11%.

  In this way, in the case where the auxiliary planting promotion / movement promotion tool 1 is not provided between two strains of cultivated plants, there is no movement from an exiled natural enemy living strain to an adjacent strain. When the auxiliary device 1 for promoting fixation / movement promotion is placed between two strains of plants, for example, the flying form of the non-flying natural enemy E shown in FIGS. 6, 7 and 8 is used. Movement of inanimate creatures that cannot be released from a released stock to an adjacent strain is permitted.

  The above experiment is an example of larvae of tobacco turtles and larvae of Nami Tentou, but it is considered that similar results can be obtained when the experiment is performed on all the natural enemy organisms that cannot fly.

  From these experimental results, it is clear that the case where the auxiliary instrument 1 for promoting establishment / movement promotion is placed between two strains of cultivated plants is more effective than the case where the auxiliary instrument 1 for promoting establishment / movement is not used. It can be seen that the migration rate is high.

  By the way, as shown in FIG. 19, the fixing promoting / moving promoting auxiliary instrument 1 may further be provided with a tubular member 4 attached to the outer periphery of the string-like member 2. For example, as shown in FIG. 19, the cylindrical member 4 has a circular shape when viewed from the axial direction. However, the shape viewed from the axial direction may be an elliptical shape or an oval shape so as not to rotate when attached to the string-like member 2. Furthermore, it may be a rectangular shape or other polygonal shapes. It is preferable that the cylindrical member 4 is made of plastic or has a water resistance and a waterproof property by coating the outer surface of paper.

  The axial dimension of the cylindrical member 4 is, for example, 5 cm, and when the total length of the string-like member 2 is 2 m, as shown in FIG. 19, a large number of cylindrical members 4 have one string-like member 2. It is attached to. Accordingly, an interval of, for example, 2 cm can be provided between the tubular members 4 and 4, and the string-like member 2 and the food material 3 attached to the string-like member 2 are exposed from this interval.

  When the tubular member 4 is attached to the outer periphery of the string-like member 2, all or part of the inner diameter is smaller than the outer diameter of the string-like member 2 so that a gap S is formed between the tubular member 4 and the string-like member 2. Is also getting bigger.

  As a result, a certain kind of natural enemy creature enters the gap S between the cylindrical member 4 and the string-like member 2 from between the cylindrical members 4 and 4, so that the cylindrical member 4 is a hidden place of natural enemy creatures ( It is possible to improve the fixation of natural enemy organisms than the eight experimental results shown in FIGS. 9 to 16 described above.
