Pine nematode vector trapping device with improved disaster prevention performance {APPARATUS FOR CATCHING INSECT VECTOR OF PINE WILT DISEASE WITH IMPROVED CONTROLLING PERFORMANCE}

The present invention relates to a pine wood nematode vector trapping device with improved disaster prevention performance. More specifically, the present invention, in capturing the vector of the pine nematode disease, includes a pheromone pocket loaded with pheromone, which is an attracting material for capturing the vector of the pine nematode disease, and the amount of pheromone released from the pheromone pocket It relates to a device that can more efficiently capture the vector of the pine wilt disease by maximizing the

The pine wood nematode is a parasitic nematode on plants, and the size is approximately 0.7 to 1.0 mm for females and 0.6 to 0.8 mm for males.

When a healthy tree is infected with pine wilt nematode, moisture and nutrients cannot move properly, so pine needles droop down and begin to wither. If a large amount of pine wilt nematode invades during a period of high temperature, symptoms appear quickly, and after about a month, the entire leaf As the trees turn brown, the trees begin to die.

The pine wood nematode cannot move from tree to tree on its own, and moves to other trees by being parasitic on the body of Monochamus alternatus, an insect vector.

The Monochamus alternatus moves as short as 100m when food is plentiful, but can move long distances up to about 4km when food is scarce.

On the other hand, in the process of taking wood infected with wood nematodes without permission and using them as building materials, fish boxes, pallets, cooking fuel, etc., damage may rapidly spread.

Until now, research on pine wilt nematodes in Korea has focused on Monochamus alternatus, which mediates them, rather than pine wilt nematodes, which have little mobility and live in host trees and have little mobility.

As it was found that the bearded alternatus also mediates, studies on this species are being conducted.

Regional distribution of the two species to date (Kwon et al, 2006), eclosion breakout characteristics by period (Kim et al, 2003; Han et al, 2009), individual morphology (Lee et al, 2004; Han et al, 2007) , distribution within pine trees (Chung et al, 2003), migration and escape from pine wood nematode vectors (Kim et al, 2009), occurrence of damage from pine wood nematode disease associated with the migration behavior of insect vectors (Kim et al, 2011), types of conifers Biological and ecological basic research, such as growth, development, and reproduction (Hwang et al, 2008), has been conducted.

On the other hand, a funnel-shaped capture frame is used as an existing trap for capturing Monochamus alternatus or Northern Mustache alternatus using these lures.

These existing capture frames are exclusively for those developed for capturing insects that harm general fruit trees or horticulture, so there is a problem in that escape occurs after being lured and captured by attractants.

Furthermore, the existing overseas pheromone traps are more suitable for moving by vehicle even though they are large and heavy because many wiltworms are distributed in plains rather than mountains in accordance with the characteristics of European countries, but they are not suitable for use in Korea with deep and high mountains Yes, there were labor costs and difficulties in installing the product.

Therefore, the present invention focused on making the product strong and light by taking advantage of the moving characteristics of "Pine mustache longhorn", a vector of pine wilt nematodes.

In addition, the present invention discloses a trap to be installed outdoors due to the nature of the product, in case of rain and with a light and durable waterproof cloth.

Furthermore, the present invention requires a work of installing and replacing pheromones in traps to attract insect vectors, but since the work takes a long time, a mesh pocket is attached to the trap waterproof cloth to easily replace the existing pheromones started possible.

On the other hand, conventionally, pesticides have been used to eradicate pine wood nematode vectors, but pesticides damage not only pests but also farmhouses, private houses, and organic cultivation places, and consequently affecting food eaten by humans.

Accordingly, the present invention was disclosed as an eco-friendly method of attracting and capturing insect vectors without eradicating them, and considering the fact that existing products are made of plastic and thus talk about problems in carbon emission, the product is a more friendly product. developed into fibers.

Patent Document 1: Korean Patent Publication No. 10-2016-0143161 (published on December 14, 2016)

Conventionally, in order to capture the "Mono mustache longhorn" and "Northern beard long beetle", which are vectors that inhabit only pine trees, pine trees, and cypress trees, it is necessary to go to a place where pine trees are gathered and install them. Since there are many traps and pheromones to install, there was a problem of carrying a large amount of traps and pheromones at once.

Accordingly, an object of the present invention is to provide a trap that can lightly and firmly install traps for pine wilt nematodes as well as other pests and at the same time provide a trap that can exhibit more efficient control performance.

A pine wilt disease vector trapping device with improved control performance is introduced.

To this end, the present invention is a head connected by a separate connection string; a support coupled to the head through a plurality of head connectors; A capture funnel having a capture hole formed at the lower end of the support with a smaller inner diameter as it goes downward; A capture waterproof cloth having a predetermined shape formed of a plurality of meshes and selectively fastened along the upper circumference of the capture funnel; and a pheromone pocket in which pheromone is supported inside the support or the trapping waterproof fabric.

In particular, the pheromone pocket may be formed of urethane vinyl, and the urethane vinyl may have a predetermined thickness.

The thickness of the urethane vinyl may be 0.1 mm to 0.5 mm, preferably 0.2 mm.

The support is characterized in that it is made of a cross type so that the insect vectors are collided and introduced into the capture hole of the capture funnel, and made of a waterproof fabric of TPU laminate component.

The capture tarpaulin is made up of a plurality of meshes and is characterized in that rainwater can fall, and a motion sensor and a weight sensor are further installed inside the capture tarpaulin, and the motion sensor and the weight sensor It is characterized in that it further includes a smart phone in which a separate application capable of interworking in real time is installed.

When the motion degree sensed by the motion sensor exceeds a set reference value or when the weight sensed by the weight sensor exceeds a set reference value, a text message or an alarm sound is transmitted to the smartphone.

According to the present invention composed of the above configuration, the following various effects are implemented.

First, in conventional traps, it was difficult to capture a larger number of insect vectors because the release of pheromone to attract insect vectors was small, but the present invention improves this and adjusts the material of the pocket for releasing the pheromone and the thickness of the material. By doing so, it is possible to capture more insect vectors and enable efficient control.

Second, in installing existing traps, if one adult can move and transport about two traps (length 1m60cm, weight 4kg), according to the present invention, the pine nematode vector trap, one adult trap (length 15cm, Weight 700g) 30 can be moved and transported.

Third, in the conventional case, when removing and installing pheromones, cable ties must be attached to and fixed to pheromones, and it takes about 5 minutes to cut each pheromone with a knife when removing it, but the present invention, the pine wilt disease vector According to the trapping device, the pheromone pocket containing the pheromone is located inside the trapping tarpaulin, so it can be easily removed and replaced, which can be removed and installed in 30 seconds.

Fourth, in the case of the prior art, when it rains a lot, there are many cases where rainwater collects in the part where the insect vectors are captured, so there are cases where the insect vectors escape. There is an advantage that does not boil.

Fifth, in autumn, many fallen leaves and foreign matter fall and block the trapping funnel hole, which often prevents insect vectors from entering. is implemented

Figure 3 is a schematic diagram of a smart phone that can be interlocked with a motion sensor, which is one component of the present invention.

Hereinafter, a preferred embodiment of a pine wood nematode vector trap with improved control performance according to the present invention will be described with reference to the accompanying drawings.

First, prior to the detailed description of the present invention, the objects and effects of the present invention will be described.

The present invention will be described in detail below, but instead of the conventional insect vector trap made of large and heavy plastic products, a space where insect vectors fly and collide is formed as a support 200, and the support 200 is made of a waterproof cloth. It is characterized by being replaced by .

In addition, it rains a lot during the period when the insect vectors are eclosion in spring and summer, and it is characterized in that the trap 400 made of a plurality of meshes is initiated to prevent rainwater from filling the inside of the trap due to rainwater to allow rainwater to fall.

Furthermore, it is characterized by initiating the pheromone pocket 500 in which the pheromone is supported inside the support 200 or the trapping waterproof cloth 400 to increase the pheromone replacement and attractive force.

According to the present invention, conventional traps are expensive, with a consumer selling price of about 150,000 to 250,000 won, and have difficulty in installing due to their large weight and volume.

Accordingly, it was designed to be easy to capture, light and easy to install in consideration of the movement characteristics of insect vectors (Monochamus alternatus, Northern mustache alternatus), and it was manufactured by replacing the insect vector capture part with waterproof fabric laminated non-toxic TPU, and the activity of the insect vector Considering the fact that the period is from May to September and the fact that it rains a lot, the part to capture the insect vectors was made of mesh to prevent the insect vectors from escaping due to water filling.

1 is an overall configuration diagram of the present invention, FIG. 2 is a photograph of the present invention actually installed, and FIG. 3 is a schematic diagram of a smartphone 800 that can be linked with a motion sensor 600, which is one component of the present invention. am.

As shown in FIGS. 1 and 2, the present invention includes a head 100 connected by a separate connection strap 10, and a support 200 coupled through the head 100 and a plurality of head connectors 110 is initiated.

The present invention is connected to the pine tree to be installed by a separate connection string (10).

A disk-shaped head 100 is located at the lower end of the connection string 10, and the corresponding head 100 is preferably formed of a lightweight plastic material.

A plurality of head connectors 110 are coupled to the lower side of the head 100, and the support member 200 is disclosed in the head connector 110.

As shown, the support 200 is formed in a cross or cross shape, and the support 200 performs a function of allowing insect vectors to collide and flow into the capture hole H of the capture funnel 300, preferably is characterized in that it is made of a waterproof fabric of a TPU laminate component.

Conventionally, heavy plastic products accounted for a large portion of the trap itself, but the present invention discloses a support 200 made of a waterproof fabric of a TPU laminate component to provide ease of installation.

On the other hand, at the lower end of the support 200, a capture funnel 300 having a capture hole H formed with a smaller inner diameter toward the bottom is disclosed. , Insect vectors attracted by the pheromone pocket 500 to be described below flow into the capture hole H and are captured by the capture tarpaulin 400 to be described below.

In addition, a trapping waterproof fabric 400 having a predetermined shape formed of a plurality of meshes, which can be selectively fastened along the upper circumference of the trapping funnel 300, is disclosed.

The capture tarpaulin 400 is characterized in that rainwater can fall through a plurality of meshes.

That is, in the prior art, when it rains a lot, there are many cases where rainwater is collected in the part where the insect vectors are captured, and the insect vectors often run away.

Accordingly, the present invention discloses a trapping tarpaulin 400 composed of a plurality of meshes to prevent rainwater from falling through the mesh and causing insect vectors to escape along with the rainwater.

In particular, in autumn, it often occurred that leaves and foreign substances fell and blocked the funnel hole for trapping, so that insect vectors could not enter. is implemented

On the other hand, the inside of the support 200 or the trapping waterproof cloth 400 includes a pheromone pocket 500 carrying pheromone.

In the case of the pheromone pocket 500 carrying the pheromone, the amount of the pheromone released is important. To this end, the present invention tried to maximize the attraction and capture of insect vectors through the release of more pheromone by adjusting the thickness of the material including the material of the pheromone pocket.

In the present invention, the pheromone pocket may be formed of urethane vinyl having a predetermined thickness.

Conventionally, since the pheromone pocket is made of general polyethylene (PE), even if there is a volatile substance inside, it is difficult to release it to the outside. There was a problem in that the amount of the substance emitted was greatly reduced.

Accordingly, the present invention, unlike the polyethylene (PE) material, uses a urethane vinyl material to increase the external emission of the pheromone material carried inside the pheromone pocket, thereby more efficiently attracting and capturing pests (vectors). control performance was improved.

In the case of the urethane vinyl forming the pheromone pocket, it is preferable to form a predetermined thickness. For example, the thickness may be 0.1 mm to 0.5 mm, preferably 0.2 mm. When using urethane vinyl having a thickness other than the above range, that is, when using urethane vinyl having a thickness of less than 0.1 mm, too much pheromone is released at once, which is rather negative for improving control performance, and can be easily torn, so durability There is a problem, and when using urethane vinyl having a thickness of more than 0.5 mm, there is a problem that efficient control performance is not secured in comparison to the case of using PE, which is a prior art (see Experimental Example 2 described later).

That is, in order to attract insect vectors, it is necessary to install and replace pheromones in traps, which conventionally took a long time.

Therefore, in order to reduce the time, the present invention discloses the pheromone pocket 500 carrying pheromone inside the support 200 or the trapping tarpaulin 400, thereby simply installing the corresponding pocket to increase the work efficiency of the operator. .

On the other hand, as shown in Figure 3, it is characterized in that the motion sensor 600 is further installed inside the capture tarpaulin 400, and a separate application capable of interworking with the motion sensor 600 in real time is installed. It is characterized in that it further comprises a phone (800).

It is characterized in that a text message or an alarm sound is transmitted to the smart phone 800 when the degree of motion sensed by the motion sensor 600 exceeds a set reference value.

That is, when the application installed on the smartphone 800 is executed, it is interlocked with the corresponding motion sensor 600 in real time, and the motion sensor 600 detects the degree of movement of the insect vectors captured in the trapping waterproof cloth 400 in real time. It is transmitted to the smartphone 800.

A reference value for the degree of movement set by an operator is pre-stored in the smart phone 800, and a text message or an alarm sound is transmitted to the smart phone 800 when the reference value is exceeded.

Furthermore, when the weight sensor 700 is further included and exceeds the set reference value, a text or alarm sound is also transmitted to the smartphone 800.

Hereinafter, the present invention will be described in more detail through specific experimental examples. However, these experimental examples are for illustrating the present invention by way of example, and the scope of the present invention is not limited to these experimental examples.

[Experimental Example 2] Pine nematode disease vector capture test for maximization of control performance

In order to find the conditions capable of maximizing the control performance of the pine nematode vector trapping device according to the present invention, the material of the pheromone pocket was selected from 0.2T of urethane vinyl (Example 1) and 0.5T of urethane After fabricating trapping devices made of vinyl (Example 2) and 0.2T polyethylene vinyl (control group), tests were conducted in the same manner as in Experimental Example 1 to determine whether each trapping device had improved trapping performance for insect vectors. did

In particular, in order to determine the amount of pheromone released from the capture device including each of the pheromone pockets before verifying the capture amount, the amount remaining after being released for 7 days was measured, and this is shown in FIG. 4 .

Referring to FIG. 4, it was confirmed that the trapping devices of Examples 1 and 2 released a larger amount of pheromone compared to the control group. In particular, when comparing Examples 1 and 2, the thinner the thickness, the higher the amount. It has been confirmed that pheromones are released.

Then, in order to specifically confirm the relationship between the amount of pheromones actually released from the stomach and the amount of insect vectors captured, the pine trees according to the present invention were found on pine trees growing naturally on the hillsides of Daundong Mountain and Iphwasan Mountain in Ulsan and Eoraesan Mountain and Geumseong Village in Gyeongju. After installing the nematode vector trapping device and the products of other companies at the same height, and maintaining the installation for about 33 days from June 22, 2021 to July 25, 2021, the captured Monochamus and Northern Monochamus. It was confirmed how many were shown in Table 2 below.
