Description

[Detailed explanation of the idea] [Industrial application field]

This invention mainly relates to a device for controlling pests that damage trees such as grapes, mandarin oranges, peaches, plums, apricots, plums, chestnuts, walnuts, cucumbers, and other fruit trees, as well as gardening trees. especially,
This invention mainly relates to a device that can effectively control the long-eared longhorn beetle, the long-eared longhorn beetle, or the long-eared longhorn moth.

[Conventional technology]

Regarding the Gomadara longhorn beetle, the following is explained in ``Diagnosis of Pests and Pests of Primary Colored Fruit Trees, Pages 28-29, Rural Culture Association, Published December 25, 1980.'' Adult beetles emerge from June to July. Adults lay eggs in July-August. Eggs are laid one by one just inside a wound in the bark.
The larvae initially feed on the underside of the bark, and as they grow a little, they may penetrate the cambium layer and some of the material. Grows for almost two years or so. Chemical control is only part of the total control of this pest. Emphasis will be placed on other methods such as capture and killing. Trees that have been eaten by the Gomadara longhorn beetles have insect droppings that look like fine wood chips pushed out from the bark. There are also many of them located slightly above the ground edge of the main trunk. They often damage the cambium layer under the bark of the main trunk by digging diagonally spiral tunnels. Once the tree goes around the main trunk, the flow of water and nutrients is cut off and the tree dies. Gomadara beetles, which cannot be controlled with chemicals, are exterminated using the following method. Capture and kill the adults when they arrive. Either kill the adult insects with a wire at the beginning of their infestation, or
Or beat him to death with a hammer. To prevent adult beetles from laying eggs, wrap the tree with cottonwood fibers or wrap newspaper around the base of the tree trunk.

[Problem that the idea aims to solve]

However, this method is extremely time-consuming because it involves inspecting every tree one by one during the period when the beetles are active. In practice, it is extremely difficult for orange and grape growers, who have extremely large numbers of trees, to prevent the damage caused by the spotted beetle using this method. In addition, the method cannot reliably prevent spawning. In the method using whitetails, if there are gaps in the whitetails that are wrapped around the trunk, the beetles can invade through these gaps. It takes a lot of effort to completely wrap the clover in a timely manner to prevent pests from entering. In addition, wrapping newspaper or the like around the material is not durable, and it easily peels off or gets damaged due to wind and rain, and loses its effectiveness in exterminating pests. The reality is that currently no effective method has been developed to efficiently prevent the damage caused by the long-eared longhorn beetle. The beetles are not the only pests of trees.
Peaches, plums, plums, apricots, etc. are affected by the stag beetle. To exterminate the larvae, the larvae are killed by scraping off the affected area with a knife around March or April, and the wound is treated with wax, etc. Extermination of these pests also requires considerable effort. Furthermore, grapes and the like are damaged by bat moths. Bat moth larvae grow by feeding on the leaves of plants and trees, and from mid-June to late July they burrow into the trunks of grapes and other plants. At first, it damages the branches, and then
It feeds on main branches and trunks. The invading bat moth causes circular damage and then burrows deep into the woody parts, causing the trees to become severely weakened and often die. Like the long-eared beetles, bat moths have a complex ecology, so no effective control methods have been established. In particular, bat moths are active at night, making them even more difficult to control than the spotted beetles. Current control methods involve weeding thoroughly in a 30 to 40 cm area around the base of the plant, and early detection of larvae that invade this area at night. Also, since they hatch from eggs and feed on plants and trees, we spray Diazin fine granules or whole granules on the undergrowth around mid-May to exterminate them. Furthermore, in the early stages of encroachment on trees, inject a 4-5 times solution of emulsion such as Sumithion or Elsan into the encroachment hole and block the encroachment hole with soil to prevent the encroachment, or if the encroachment hole is shallow. , and kill him by sticking an iron needle into the hole. Bat moths that have invaded deeply cannot be killed by pricking them with iron needles, making it almost impossible to control them. No matter which control method you use, it is extremely difficult to carefully manage all of the large numbers of grapes and other trees over a long period from June to July. The reality is that the yield is decreasing. The present invention developed a device having the structure shown in Fig. 4, and succeeded in effectively exterminating the Japanese curlew moth (Japanese Patent Application No. 62-314935). This control method involves providing a barrier groove around the trunk and filling the barrier groove with water. This control device was installed on approximately 600 vines by mid-May, when bat moths are active.
Afterwards, two grapes were observed to be eaten by bat moths. Although this control device could effectively prevent the feeding damage of bat moths, it could not completely eliminate them. If the theory that bat moths crawl on the ground and feed on grapes is correct, then a control device with this structure can completely eliminate bat moth infestation.
However, in reality, bat moths invaded the ground edges of the two grape trunks. The inventor was unable to determine the route by which the invading bat moth entered the tree. However, the present inventor discovered that bat moths lay eggs while flying, and these eggs attach to grape leaves.
It was discovered that this hatches and moves to the ground edge of the trunk, where it feeds. Although there are significantly fewer bat moths that eat this way than those that crawl up from the ground, we found that they do eat this way very rarely. The technology to control the beetle beetle was developed in 1972.
-Described in Publication No. 139887. The pest control device described in this publication wraps a hollow nonwoven fabric, which is finer than the eggs of the beetle beetle, around the lower part of the tree trunk. The lower edge of the nonwoven fabric is fixed to the ground with a nail-like fastener. The non-woven fabric is wrapped 10 to 30 centimeters above the ground, where the beetles fly and prefer to lay their eggs. The non-woven fabric prevents the spotted beetle from laying eggs on the tree. Furthermore, even if a pest tries to crawl up, its legs and claws become entangled in the nonwoven fabric and it is trapped. When a pest control device with this structure functions in an ideal state, it can prevent pests from spawning. However, with a nonwoven fabric having this structure, it is difficult to reliably prevent damage from pests. This is because the nonwoven fabric is fixed to the ground with fasteners, so the lower edge of the nonwoven fabric cannot be fixed to the ground immediately, and pests can enter the back of the nonwoven fabric from between the nonwoven fabric and the ground. By placing soil on top of the nonwoven fabric fixed in the ground, pests can be prevented from entering the back side of the nonwoven fabric. However, in reality, it is not possible to prevent pests from entering the back side of the nonwoven fabric from the outer periphery in this way. The reason for this is that it is difficult to keep soil on the entire circumference of the nonwoven fabric forever due to wind and rain. The non-woven fabric vibrates when blown by the wind, and the soil is washed away when rainwater flows.
It is extremely difficult to keep soil on the outer periphery of the nonwoven fabric for a long period of time, and the soil disappears in some areas, creating gaps between the nonwoven fabric and the ground, which allow pests to enter. This invention was developed to further solve this drawback, and the important purpose of this invention is to reliably exterminate pests such as the bat moth, the long-eared beetle, and the long-eared beetle in an extremely effective and labor-saving manner. The goal is to provide equipment.

[Means to solve conventional problems]

The pest control device of this invention has the following configuration. The pest control device includes a buried ring 1 and a breathable sheet material 2 connected to the buried ring 1. The buried ring 1 has a divisible annular shape as a whole so that it can be attached to the ground edge of a tree, and has a trunk hole 3 in the center through which the tree trunk can pass. The sheet material 2 is still used to prevent pests from entering the ground edge of the trunk and causing damage.
The overall shape is cylindrical, and the lower edge is connected to the buried ring 1 through a gap through which pests cannot penetrate. A flexible binding member 4 is provided at the upper end of the sheet material 2 to be tied to the trunk to prevent pests from entering the ground edge of the trunk from above. The sheet material 2 has ventilation holes through which pests cannot pass through, so that pests do not enter through it. In order to prevent pests from entering the ground edge of the trunk with the buried ring 1 and the sheet material 2, the length between the lower end of the buried ring 1 and the upper end of the sheet material 2 is set as follows.
Made over 10cm. Furthermore, the buried ring 1 is provided with a barrier groove 5 which is open upward and has a watertight structure. The sheet material 2 is connected to the side periphery of the barrier groove 5 of the buried ring 1 so that it can be installed directly between the buried ring 1 and the ground. The buried ring 1 includes a buried protrusion 11 that protrudes downward from the barrier groove 5 and is buried underground.

[Preferred embodiment]

Hereinafter, embodiments of this invention will be described based on the drawings. However, the embodiments shown below illustrate a pest control device for embodying the technical idea of this invention.
The shape, structure, and arrangement are not limited to the following structures. Various changes can be made to the pest control device of this invention within the scope of the claims for utility model registration. Further, in this specification, numbers corresponding to the members shown in the embodiments are added to the members shown in the claims for utility model registration so that the claims for utility model registration can be easily understood. However, the members described in the claims for utility model registration are by no means limited to the members shown in the examples. The pest control device of this invention is mainly installed on grapes, peaches, plums, apricots, plums, mandarin oranges, chestnuts, walnuts, cucumbers, etc., and is used to control pests that feed on the ground edge of the trunks, such as the long-eared beetle, the white-spotted moth, and the bat moth. . The pest control device shown in Figure 1 consists of a buried ring 1
and sheet material 2. The buried ring 1 has a divisible annular shape as a whole, and has a trunk hole 3 in the center through which a tree trunk can pass. The buried ring 1 is made of durable synthetic resin, metal, or the like. The divisible embedded ring 1 preferably has a structure that can be divided into two in the diameter direction. It is preferable that the connecting portions of the divided embedded rings 1 be shaped so that they can be connected quickly and easily. The buried ring 1 having the barrier grooves 5 opening upwardly needs to connect the barrier grooves 5 in a water-tight manner.
This is because the barrier groove 5 is filled with water. The embedded ring 1 can be connected in a watertight manner by closely adhering the connecting portions with an adhesive or by coating the connecting portions with an adhesive. In the embedded ring 1 shown in FIG. 1, an outer cylinder 8 and an inner cylinder 7 are connected by a bottom plate 6. The bottom plate 6 connects the lower end of the outer cylinder 8 to the outer surface of the middle cylinder 7. A barrier groove 5 open at the top is provided between the outer cylinder 8 and the middle cylinder 7. The middle cylinder 7 extends downward from the outer cylinder 8, projects downward from the barrier groove 5, and has a buried protrusion 1.
1 is formed. The lower end of the middle tube 7 constituting the buried convex strip 11 is formed sharply so that it can be smoothly pushed into the ground. The lower end of the middle cylinder 7 is pushed into the ground. In this state, the outer periphery of the trunk is surrounded by a partition wall that prevents pests from entering. A sheet material 2 is connected to the upper edge of the middle cylinder of the embedded ring 1, that is, to the inner peripheral edge of the barrier groove 5. The sheet material 2 is connected to the upper end of the middle cylinder, which is the inner periphery of the barrier groove 5, to prevent pests from penetrating between the embedded ring 1 and the sheet material 2. The third structure is to easily connect the sheet material 2 to the inner cylinder.
As shown in the figure. The sheet material 2 shown in this figure is connected to the inner tube 7 with clamps 9. Pincer 9
is made of an elastic material such as metal or hard synthetic resin, and is shaped like an inverted U. This clamping tool 9 places the sheet material 2 along the upper end of the middle tube 7, and clamps the middle tube with the sheet material 2 covering the middle tube. The clamping tool 9 is arranged at a certain interval between the sheet material 2 and the middle tube 7 so that there is no gap between the sheet material 2 and the middle tube 7.
For example, sheet materials 2 are sandwiched between embedded rings 1 at intervals of several centimeters. The clamping tool 9 having this structure has the advantage of being able to simply and reliably connect the sheet material 2 to the embedded ring 1. The sheet material 2 can be made of flexible fibers, such as a net woven from synthetic fibers, a breathable woven or nonwoven fabric, or a synthetic resin sheet with a large number of ventilation holes. The sheet material 2 prevents pests from entering. Therefore, the sheet material 2 has ventilation holes through which pests cannot pass, in other words, ventilation holes that are smaller than the pests. If the ventilation holes in the sheet material 2 are made large enough to prevent pests from entering, and if the number is increased, ventilation is improved. The upper end of the sheet material 2 is tied to the trunk. In order to prevent pests from passing between the sheet material 2 and the trunk, the sheet material 2 is connected to the trunk at a gap through which pests cannot pass. A flexible binding member 4 is provided at the upper end of the sheet material 2, and the sheet material 2 is bound to the trunk with this binding member 4. The length between the lower end of the buried ring 1 and the upper end of the sheet material 2 is adjusted to a range of 10 to 150 cm. If this length is short, only the low part of the trunk will be covered with sheet material.
It cannot be covered with The sheet material and the embedded ring 1 having this length can efficiently control pests that invade the ground edge of the trunk. If this interval is too short, only the lower part of the trunk can be covered with the sheet material 2, and pests will eat into the area covered by the sheet material 2. Also,
If the sheet material 2 is too long, the material cost will increase and the product will be expensive. The buried ring 1 shown in FIG. 1 is provided with a barrier groove 5. The barrier groove 5 is preferably formed to have a width of 1 cm or more so that larvae such as bat moths do not cross over the barrier groove 5. Bat moth larvae have a body length of 5~
Although it is 7.5 cm, it does not exceed the water-filled barrier groove 5, which is narrower than its body length. This is because the bat moth larva approaches the water 10 in the barrier groove 5 and avoids the water 10 when its antennae touch the water 10. Although barrier grooves 5 having a shallow depth can be used, shallow barrier grooves 5 do not retain water well and must be replenished with water. In particular, this pest control method is used during the rainy season and early summer when the temperature is high, so water evaporates easily. Therefore, the barrier groove 5 is preferably as deep as possible, for example, 1 cm or more. By applying a thin oil film to the water stored in the barrier groove 5, water evaporation can be reduced. An oil film is formed when oil is added to water and it floats on the water and spreads. Even when water is replenished, oil always floats on the water surface and prevents water from evaporating. The lower end of the buried convex strip 11 is buried underground in the barrier groove 5 so that bat moth larvae do not pass through the barrier groove 5. The barrier groove 5 having this structure can be easily fixed around the trunk by pushing the lower end of the middle tube 7 into the ground. By the way, if undergrowth grows over the barrier groove 5, bat moth larvae will cross over the barrier groove 5, so it is better to remove the undergrowth to prevent weeds from crossing over the barrier groove 5. . Sunlight does not pass through the area where the undergrowth has been removed,
By laying a synthetic resin film colored in a dark color such as black, it is possible to prevent undergrowth from growing.

[Effect of the idea]

In the pest control device of this invention, the lower end of the sheet material is connected to the inner peripheral edge of the barrier groove of the buried ring, and the buried ring is further provided with a buried convex strip that projects downward from the barrier groove. A pest control device having this structure has the advantage of being able to reliably prevent pests from entering the back side of the sheet material. The inner periphery of the barrier groove is different from the ground and has a shape that allows the sheet materials to be connected without any problems. Therefore, by connecting the sheet material here, there is no space between the sheet material and the buried ring for pests to enter. moreover,
Since the buried ring has a buried protrusion that protrudes downward, by inserting the buried protrusion into the ground and burying it, there is no path for pests to enter between the ring and the underground.
Furthermore, even if the sheet material is vibrated by the wind, the buried ring, in which the buried protrusions are buried and fixed underground, will not vibrate. Therefore, even if the sheet material is vibrated by the wind, there is no path for pests to enter the back surface of the sheet material. Furthermore, even if some soil is washed away by rain, since the buried protrusions are buried underground, the bottom ends will not be exposed to the ground, and pests will not be able to invade the back side of the sheet material from the buried rings. can be effectively prevented. In particular, the buried protrusions are inserted into the ground and fixed, so they do not easily flow away, unlike soil placed on non-woven fabric. Therefore, the insect pest control device of this invention has the advantage of being able to extremely effectively and reliably exterminate insect pests such as the bat moth, the long-eared beetle, and the long-eared longhorn beetle even with the sheet material. Furthermore, the pest control device of this invention does not require the trouble of fixing the sheet material underground and placing soil on it, and the upper end of the sheet material is tied around the outer circumference of the tree, and the buried convex strip is buried in the ground. It also has the feature that it can be easily and quickly installed on many trees by pushing it into the ground. In addition, since the pest control device of this invention covers the lower end of the tree with a breathable sheet material, this part has good ventilation and has the advantage of preventing this part from becoming damp and becoming parasitic with viruses. Trunks covered with breathable sheet material can also prevent death due to high temperature damage. Furthermore, since the pest control device of this invention buries and fixes the buried convex strips underground, it requires no maintenance after installation, and unlike conventional pest control methods, it does not require repeated visits to the garden. There is no need to search for pests by searching for pests, and it is possible to realize the feature of preventing pest feeding damage in an extremely labor-saving manner. Therefore, by installing the pest control device of this invention on trees in orchards, yields can be increased without much effort. Furthermore, a noteworthy feature of this invention is that since pests are controlled without the use of chemicals, the fruit is not contaminated with pesticides at all, and delicious, safe food can be harvested and eaten with peace of mind. In particular, the pest control device of this invention has the advantage of being able to extremely effectively exterminate pests such as the long-eared beetle, the long-eared beetle, and the bat moth, which are extremely difficult to exterminate. This is because most of these pests feed on the ground. Therefore,
The pest control device of this invention can effectively control most pests. By the way, pests that invade areas other than the ground can be exterminated relatively easily. Grapes, mandarin oranges, peaches, plums, apricots, plums, chestnuts, walnuts, cucumbers, etc. are not used to look for pests, but in order to produce fine fruit, it is important to take good care of the areas where the fruit grows. That's the reason. Also, if pests invade the ground, they will weaken the entire tree, but if they invade the branches of a tree, they will only partially weaken the branch, causing very little damage.
