Description

Trap for catch Bemisia tabaci}

The present invention relates to a trap for catching tobacco whiteflies for controlling tobacco powdery mildew (white powdery mildew) in facility crop cultivation and open-field horticultural crops.

About 1,200 species of whitefly are recorded worldwide, and 7 species are reported in Korea, and the most problematic are the greenhouse whitefly and tobacco whiteflies.

The preferred host plants of the tobacco whitefly (Bemisia tabaci (Gennadius)) are cucumbers, melons, watermelons, pumpkins, melons, eggplants, tomatoes, and potatoes, and it started to occur heavily in red peppers, including green peppers, paprika, and green peppers.

Among them, the tobacco powdery mildew (Bemisia tabaci) that occurred in Korea belongs to the family Aleyrodidae of the order Homoptera, and although the incidence density is low, it mediates various kinds of virus diseases in crops, causing disease outbreaks and physiological changes in plants, causing damage. It is reported as a B strain (B biotype) with strong fertility (Lee et. al, 2000). And because it has a wide host range, it also occurs in most greenhouse crops and surrounding weeds, sucks plants, and leads to damage due to the transmission of viral diseases and reduced production. When the tobacco powdery sucks, the crop is weakened and withered, and the growth rate and yield of the crop are reduced (Berlinger, 1986), which causes the leaves to discolor or fall, which can lead to the death of the crop. In addition, poisoning of juice and excretion of nectar after sucking inhibits photosynthesis and affects the yield of fruit (Glii, 1990), the leaves of tomatoes turn silver or the fruit ripens unevenly, and soot disease on the leaves and fruit is induced. make it

And when soot disease occurs, photosynthesis is reduced as well as crop productivity (Berlinger, 1986). In addition, in the case of tobacco powdery mildew, it can cause great damage even at low density when it mediates viruses (Cohen and Berlinger, 1986). It is also a pest of great concern.

Tobacco powdery mildew is a pest that occurs in tropical or subtropical regions, but is currently a worldwide problem in Europe, the Mediterranean, Africa, Asia, and the Americas. After that, from 2004, some tomato growers in Gyeongnam and Jeonnam started to become a problem, and in 2005, it spread to a wide area including red pepper crops. And in 2006, it spread to all regions of Korea except for some regions of Gangwon-do. It was predicted that it would spread all over Korea from 10 years ago and cause economic damage. The life history of whitefly, such as tobacco whiteflies and greenhouse whiteflies, is egg-->1st instar (movable 1st instar crawler)-->2nd instar nymph-->3rd instar nymph-->4th instar nymph (pupa stage) )--> It has a stage of development into an adult, and among them, the 2nd to 4th instar nymph stage is the stage of development by fixing without legs.

The life cycle of tobacco whiteflies is similar to that of greenhouse whiteflies. In cotton, it is known that one female lays an average of 70-80 eggs (Butler et al. 1983). Immediately after hatching, first instars are mobile, but once settled, they lead a sedentary life. There is a big difference depending on the type of food and the temperature, and the nymph becomes an adult after 2 to 4 weeks of nymph. They move a short distance from the spawning site to the spawning site, and the distance does not exceed 4-5 m (Berlinger. 1986).

Tobacco powdery eggs are shell-shaped, with egg stalks attached to the stomata or the leaf surface. Generally, in crops without fine hairs, they lay eggs in a circular shape, and in hairy crops, they lay eggs without a uniform shape. The color of the eggs is pale yellow immediately after spawning, and gradually changes to a light brown system over time.

It is very difficult to distinguish the two species at the nymph stage, but it is possible to distinguish them at the egg and pupae stage. Newly laid eggs are all light yellowish white, so it is difficult to distinguish them, but as time goes by, they have their own dark color. Greenhouse whitefly eggs turn black, and tobacco whitefly eggs have a dark yellow color. Greenhouse whitefly pupae have well-developed large and small projections that secrete wax, but tobacco whiteflies do not have a special projection structure. Greenhouse white pupae have a white color and are thick enough to give a plump feeling, whereas tobacco white pupae have a yellow color and are flat like a disk. The 1st instar nymphs of tobacco whiteflies are 0.25mm in size and have legs so they can move around, and the 2nd instar nymphs change to a flat shape and develop a fixed life up to the 4th instar nymphs (0.8mm). And all stages of the nymph are pale yellow (off-white system), which distinguishes them from the nymphs of G. nymphs. In the pupa stage, red eyes are formed in the state of the 4th instar nymph. Greenhouse whitefly has a lot of hair, but tobacco whitefly has sparse hair so that it is hardly visible, and the body color is pale yellow (off-white).

The development period from egg to adult takes about 18 to 20 days at 25°C, and the lifespan of an adult is about 10 to 25 days. The female adult can lay about 170~230 eggs in the case of tomato and eggplant crops. Although it is not easy to distinguish between the greenhouse whiteflies and the adult tobacco whiteflies by the appearance, the body length (length) of the adult tobacco whiteflies is about 0.8mm, and it is slightly smaller and elongated than the greenhouse whiteflies (triangular shape). The wings are also narrower and longer than the greenhouse whiteflies, so even with the naked eye, they feel much smaller than the greenhouse whiteflies. Comparing the appearance when the wings are folded and resting, in the case of the greenhouse whitefly, both wings overlap, whereas in the tobacco whitefly, the wings are slightly apart. The body color is pale yellow, and the surface of the wings is covered with more white powder composed of wax.

Tobacco whitefish prefers 25-30℃, and in the case of adult females, it can survive for about 10-15 days at 28-30℃ above the freezing temperature, and about 1-2 months in winter when the temperature is lowered. In addition, it can survive for several weeks even at low temperatures in the growing environment without host plants. However, it cannot survive below 0℃. In the case of tobacco powdery mildew, growth stops at temperatures below 16°C, and if the relative humidity is low in the growing environment of 9°C or below, the density of occurrence rapidly decreases or death occurs. The spawning habits of adult tobacco whiteflies are different from those of greenhouse whiteflies. In the case of greenhouse whitefly, eggs are laid on the upper part of the shoot of the crop, but in the case of tobacco whiteflies, eggs are laid on the back of the leaf from the entire part of the crop regardless of the top and bottom of the crop. Therefore, all the various growth stages from one leaf to the egg to pupa of a crop can be identified.

Among the harmful characteristics of tobacco powder, the nymphs and adults suck crops and excrete nectar, so the photosynthetic ability of tomatoes, paprika, eggplant, etc. is reduced, resulting in irregular coloration, and among other harmful characteristics, In this case, tobacco powdery mildew can mediate more than 25 kinds of viruses to crops, and it also mediates pathogens similar to viruses like TYLCV (tomato yellow leaf curl virus) in tomatoes, causing serious damage worldwide, and the degree of insecticide resistance is very high. It is also a high heating agent pest.

Currently, the only trap that is being used for the purpose of monitoring and controlling tobacco powdery mildew is the yellow sticky trap. This is because whitefly, including tobacco whiteflies, are microscopic insects and are more attracted to yellow than any other color.

According to the search by the present applicant, Patent Documents 1 to 3 are disclosed as prior art related to the present invention. a central trap unit; It is an adhesive trap made of; a background part made of a color complementary to the color of the trap part, and the area ratio of the trap part and the background part is 1:5 to 1:10.

The 'Smart Greenhouse Pest Greenhouse Eco-Friendly Unmanned Collecting Device' of Patent Document 2 attracts and removes whitefly-type pests such as greenhouse powder and tobacco whiteflies using ultraviolet rays to prevent the spread of pest populations and damage crops caused by chemicals. In addition, it is designed to improve the convenience and safety of workers through remote control using smart devices.

In addition, the 'eco-friendly unmanned insect pest dust collector used in greenhouses' of Patent Document 3 removes pests of the white family such as greenhouse dust and tobacco whiteflies by using ultraviolet and ozone through forced inhalation and chemical attraction to the leaves of crops. By adsorbing and removing pests located on the back surface, it is possible to prevent the spread of pest populations and to prevent damage to crops due to chemicals.

Korea Patent No. 0-0853616 (Registered on August 14, 2008) Korean Patent Registration No. 10-1819426 (Registered on Jan. 10, 2018) Korean Patent No. 10-1945482 (registered on January 29, 2019)

The present invention aims to effectively control tobacco powdery mildew in facility crop cultivation and open-field horticultural crops. The purpose is to reduce the frequency and to satisfy the demand for eco-friendly agricultural products by safely producing high-quality, eco-friendly agricultural products.

In order to achieve the above object, the present invention basically uses the basic property that whiteflies are attracted to yellow, and scatters sunlight to increase the sensitivity of whiteflies to yellow by scattering sunlight, thereby increasing the attraction force compared to the existing yellow sticky flat trap. made it possible to represent

In addition, a black base was grafted on the lower part of the body to visually emphasize the yellow attracting adhesive trap of whitefly.

Yellow attracts not only whitefly, but also many insects, including flies. For this reason, frequent replacement occurs with the adhesion of unspecified insects rather than the replacement of the adhesion trap due to the desired adhesion of powdery mildew in the field. Therefore, in the present invention, since the yellow adhesive trap is located in the body, the adhesive situation by unspecified insects is dramatically reduced, so there is no unnecessary replacement of the adhesive trap, and relatively accurate observation is possible when used for the purpose of observation.

According to the present invention, it is possible to maximize the attraction effect by improving the sensitivity of yellow due to the scattering effect of sunlight, and since the adhesive trap is located inside the body, the adhesion of unspecified insects, not the whitefly, is reduced, and frequent replacement of the adhesive trap is not required. , accurate observation is also possible, and there is no inconvenience in checking the inspection or replacing the adhesive trap. This has the effect of reducing the labor required for year-round control and protecting the health of farmers and consumers from damage caused by synthetic pesticides by managing the individual and population of tobacco powder, a major pest in horticultural crops, from a more comprehensive point of view. there is

Hereinafter, preferred embodiments that do not limit the present invention will be described in detail with reference to the accompanying drawings.

1 to 3, there is shown a trap 1 for catching tobacco powder according to an embodiment of the present invention, which has a body 10 having an attracting and trapping function, and detachably at the lower part of the body 10 It consists of a base 20 to be coupled.

The body 10 has a generally cylindrical shape with a closed upper portion and an open lower portion, and is made of a translucent synthetic resin that allows light to pass through, and the color is yellow.

A canopy 12 on the upper surface of the body 10 serves as a filter for scattered light and refracted light. An empty space is provided inside the body 10 in which a flat yellow adhesive trap (not shown) can be mounted.

In this embodiment, the canopy 12 is simply formed of a sawtooth shape in which bones and mountains alternate, but the present invention is not limited thereto and may be formed in various shapes of curves. In the case of the trap 1 installed in the field (outside) as well, it has a radially curved shape.

In the trap 1 according to this embodiment, the above-described canopy 12 serves as a kind of refractive filter. causes an amplified illusion, and the scattered light makes the color of the yellow adhesive trap located inside the body 10 more clearly visible, thereby maximizing the attraction effect.

In the present embodiment, the inside of the body 10 is not shown in the drawing, but a yellow adhesive trap of a circularly rolled or flat plate type is located. The circular body 10 spreads the transmitted and scattered light throughout the yellow adhesive trap 1 .

In addition, on the outside of the body 10, a ring 14 for hanging the trap 1 protrudes in all directions, which is effective when the trap 1 is vertical on the crop, so that it can be maintained horizontally. should be hung from the

The base 20 has a generally flat disk shape, and is made of an opaque synthetic resin material that does not transmit light and has a black color. A circular inlet 22 is provided at the center of the base 20 , and a fastening part 24 connected to the body 10 is provided.

The base 20 prevents light passing through the body 10 from going downward except for the central inlet 22 .

The color of the base 20 is black and serves to visually highlight the yellow body 10 and the yellow adhesive trap inside the body 10 .

In this embodiment, the fastening part 24 has a polygonal shape with several small angles. Although not specifically shown in the drawing, the lower end of the body 10 covers the outer side of the fastening part 24 and then fits in one direction. It consists of a rotary tightening type that is fixed and coupled immediately by turning it.

Each number of the polygon to which the lower end of the body 10 and the base 20 are coupled must be the same, and an 18-gonal shape is suitable based on a diameter of 10 cm. Increase the three angles when the diameter increases by 2 cm.

On the other hand, it can be said that tobacco powdery mildew and whitefly are the most adapted pests to pesticides. When the epidermis is covered with wax, such as tobacco powdery mildew and whitefly larvae, it is difficult to penetrate the pesticide into the insect body, and since direct contact is not easy, the degree of insecticide resistance is high. However, among powdery mildew found in Korea, tobacco powdery mildew is reported as an ecological type of B biotype (B strain) that causes damage by mediating various kinds of viral diseases in crops even though the occurrence density is low, causing disease outbreaks and physiological changes in plants. (Lee et. al, 2000). Tobacco powder of B biotype (B strain) has a strong fertility and has a very high degree of resistance to pesticides, so it is becoming more and more of a problem.

Synthetic pesticides (crop protection agents, broad-spectrum insecticides) that can simultaneously kill several species of insects (pests + natural enemies + general insects, etc.) The use of a lot of synthetic pesticides such as carbamate, synthetic pyrethroid, and organophosphorus, which can be a problem because they remain on crops, should be avoided. And organic phosphorus-based, carbamate-based, synthetic pyrethroid-based synthetic pesticides are also insecticides widely used in the control of powdery mildew and tobacco powdery mildew. When using synthetic pesticides (crop protection agents, pesticides), pesticides that kill pests well, but do not damage natural enemies, general insects (insects harmless to cultivated crops) and crops should be used. In addition, pesticides with low side effects on insects and high selectivity for tobacco powdery mildew and whitefly must be used.

However, tobacco powdery mildew and powdery mildew occur year-round in most plant and fruit vegetables (cucumber, pumpkin, watermelon, melon, melon, tomato, cherry tomato, strawberry, red pepper, eggplant, etc.) For safety reasons, it is desirable to reduce the use of synthetic pesticides in controlling tobacco powdery mildew and powdery mildew in any case. In order to reduce the amount and frequency of use of these synthetic pesticides, it is very important to use pesticides with a short retention period and high selectivity for target pests, and to reduce the number of annual sprays and to protect natural enemies.

In order to reduce the excessive spraying of synthetic pesticides (insecticides, crop protection agents), sufficient natural enemies must be generated in advance in order to reduce excessive spraying of synthetic pesticides, but in reality, natural enemies often die due to synthetic pesticides. It is limited to repetition. It is difficult to expect the occurrence of natural natural enemies in real horticultural crops and the suppression of the density of tobacco powdery mildew and powdery mildew through natural enemies. Therefore, it is necessary to reduce the use of synthetic pesticides by a sufficient amount first, so that natural enemies can be expected to naturally increase the amount thereafter.

Even when natural enemies are artificially released by using natural enemies as biological control agents, the application period of synthetic pesticides and duration of toxicity must be considered before use. However, there are some complex factors that are difficult to fully consider as there are some complex factors to consider, such as light emission and spraying of synthetic pesticides, along with environmental conditions (temperature, humidity, amount of sunlight, etc.). In some cases, even when different types of synthetic pesticides are applied to prevent the appearance of cross-resistance to tobacco powdery mildew and whitefly insecticides, broad-spectrum insecticides such as synthetic pyrethroids disappear within hours or days, but the remaining half-life There is also a point that the type of insecticide used throughout the year and the frequency of application increase as the is shorter.

Therefore, in order to safely produce high-quality, eco-friendly agricultural products and satisfy the demand for eco-friendly agricultural products while the amount of tobacco powder and powdery mildew is maintained below the economic damage tolerance level, the annual usage and frequency of use of synthetic pesticides must be reduced. Even if it is necessary to use , synthetic pesticides with high selectivity should be used, and the necessary conditions to protect natural enemy insects should be considered together. In addition, as a complementary measure to the factors that increase the occurrence of continuous changes in environmental conditions (temperature, humidity, sunlight, etc.) in facilities and open-field cultivation areas, we propose a sun-illustration trap for tobacco powdery mildew and powdery mildew. This continuously and continuously suppresses the increase in the occurrence density of tobacco powdery mildew and powdery mildew, thereby reducing the use of synthetic pesticides (insecticides, crop protection agents), and temporally and spatially supplementing the occurrence of natural enemies that are slower than the pest occurrence rate. will play a role In addition, the background (complementary color) vs. bit trap is continuous even in the environmental conditions of the cultivated area with complex factors, and the inhibitory function against tobacco powdery mildew is continuously maintained, and due to the rapid change of environmental factors in the cultivation area, There is also a complementary function of monitoring (prediction) when the density (amount) of tobacco powdery mildew (powdered powdery mildew) increases rapidly within a short period of time.

Even when used in the same space, these complementary measures should have little or no effect on the maintenance of the density of the natural enemy insects of tobacco whiteflies and the proliferation after new occurrence. In addition, it is possible to continuously and continuously suppress the density of tobacco powdery mildew and powdery mildew without being affected by the use of synthetic pesticides or the increase or decrease in the density of natural enemies, and can predict (monitor) sudden changes in the density of occurrence. it should be

As consumers' interest in safe agricultural products increases, organic or pesticide-free cultivation in horticultural crops is spreading. However, there are some things that are thought to be eco-friendly by the name of eco-friendly itself, but are not related to eco-friendliness at all or have not yet been verified.

For the control of tobacco powdery mildew and powdery mildew, in the case of facility cultivation, insect screens are installed on the side windows to prevent the intrusion of pests from outside, and double doors are installed at the entrance to prevent pests from entering the inside. In addition, materials known to be effective in controlling pests include the use of UV-removing films, light-reflecting films, and yellow lamps. The use of such materials can reduce the occurrence density of pests, helping to use natural enemies that have a control effect at low pest density. Unlike pesticides and organic materials, these materials do not affect natural enemies as they do not cause any disturbance or physical damage to the ecosystem.

However, protection of native natural enemies is the key to pest control in open-field and facility-grown crops. Natural enemy protection is the restoration of the food chain, reducing the population density of pests below the level of economic damage. Many farms that have been certified for eco-friendly cultivation (no pesticides, organic cultivation) are actually grown in crop cultivation year-round because eco-friendly agricultural materials registered as fertilizers are broad-spectrum pesticides (crop protection agents with a very wide pesticide range), and there is no selectivity for the pests to be controlled. It seems that we have forgotten that natural enemy insects, beneficial insects for crops, and the process of killing even harmless general insects without causing any damage to crops during crop cultivation are occurring repeatedly and sometimes continuously.

This not only kills pests, but also causes the re-emergence of pests that cause damage by killing natural enemies and general insects. The increase in the frequency of use of these broad-spectrum pesticides also leads to an increase in the amount of use per area during one control along with an increase in the number of control throughout the year. And if the number of times of reuse of the same pesticides in the broad-spectrum pesticides is high during the year, or if a specific ingredient is repeatedly used among pesticides of different classes, there is a problem that leads to the appearance of pests with resistance to the drug substance. The emergence and occurrence of these resistant individuals also shows that the background of pest control is not centered on synthetic pesticides (insecticides, etc.), but that the basis of pest control should be converted to comprehensive control. In addition, the transition to comprehensive control can be found in the agricultural policies of advanced countries and the successful cases of cultivation of various eco-friendly crops.

If you have recognized that all pests do not cause economic damage, you will need to find a way to compensate for this. And the comprehensive control of whitefly (whitefly) can be found in complementing the complex interrelationship of reducing the use of synthetic pesticides and protecting natural enemies of insects.

This comprehensive pest control has achieved a change in the background and fundamentals of pest control by using the environment and various technologies in a complex (complementary) way. Comprehensive pest and pest management is being practiced.

Comprehensive pest management technology is a method for determining control to suppress the excessive use of synthetic pesticides in crop cultivation areas and to ensure agricultural safety, environmental friendliness, sustainability and international competitiveness. It is also a way to reduce health damage to farmers and consumers by improving the cultivation environment (agricultural ecosystem) and contributing to the preservation of the natural environment (natural ecosystem).

This minimizes the economic damage caused by powdery mildew in the short term by using traps against the background (complementary color), and in the long term, the amount of tobacco powdery mildew is low enough that it is not an economic problem. It is a method to protect cultivated crops by managing the density of tobacco powdery mildew and powdery mildew so that it can be maintained in And by suppressing the increase in the density of occurrence, it is a method to keep the environment of the cultivated area, which is an agricultural ecosystem, as stable as possible and maximize production efficiency.

[Example]

The attractiveness of the trap according to the present invention was evaluated through an outdoor experiment on tobacco powdery mildew.

Experiment period: September 02, 2020 ~ October 28, 2020

Experimental location: Imja-myeon, Andong-si, Gyeongsangbuk-do

Experimental method ① Prepare the experimental group and control group (commercial product) in 3 repetitions. ② For the control group, select a yellow adhesive trap with a width of 15 cm and a height of 25 cm. A yellow sticky trap of the same size is also used in the experimental plot. ③ Install the experimental group and control group vertically on the pepper in the pepper packaging. ④ Install the experimental zone and the control zone at least 5m apart. Repetition varies house dong. ⑤ Irradiation is conducted once a week, and the positions of the experimental group and the control group are randomly changed for each irradiation.

Tobacco powdery attraction experiment was conducted in an open-air red pepper cultivation field located in Immyon, Andong-si, from September 02 to October 28, 2020 in the same way as above. The red pepper cultivation field was abandoned due to the rainy season in the summer and had sufficient conditions for tobacco powdery to live. However, the temperature during the experiment was lower than usual and there were many days with strong winds, so there was not a lot of tobacco powder. However, it was in a sufficient state for the evaluation experiment.

The amount of tobacco powdery lice generally increased in September, when the experiment started, and then decreased in October. The pattern of decrease became 0 as of October 22. As October entered, the temperature dropped due to strong winds, and the population decreased sharply.

As a result of the experiment, an average of about 126 mice was captured in the experimental group as shown in Table 1 and the graph of FIG. 5, and an average of about 35 mice was captured in the control group. Experimental groups were captured more than 3 times more than the control group. In all of the repeated experiments, the experimental group showed a higher trapping power than the control group, and the difference was severe. Comparing the weekly averages, it was more than doubled in the surveys on September 16 and 23, and the difference was more than four times in the other surveys. However, in the case of the September 23 investigation, a problem occurred in the experimental area (c), and the trap fell to the ground due to the strong wind. Due to the fact that it was on the ground, catching was not done well, and the average was lowered. Under normal circumstances, it is estimated that September 23rd would have produced more than double the results.

The trap for trap of this embodiment has a curved canopy (canopy) forming a constant angle made of a transparent PP material. The light passing through this canopy produces a scattered light that appears to be the Tyndall phenomenon, and mixes with the yellow color of the yellow sticky trap to visually induce the illusion of high stimulation. In addition, the angle of the bending filter (curved upper part) causes refraction of sunlight, allowing light to enter the body better, and the black base makes the yellow inside the body more distinct, sharply increasing the attraction of the tobacco powder. gave.

In conclusion, the fact that the trap of this embodiment induces three phenomena: the illusion of high stimulation through scattered light, the internal attraction of light by the bending filter, and the yellow relief by the black base plate, thereby increasing the attraction of the tobacco powder. was confirmed through the experiment.

6 shows the case in which the upper canopy is curved in the trap according to the present embodiment and the case in which the upper canopy is formed in a simple flat shape. is amplified, and the scattered light makes the color of the yellow sticky trap located inside the body more clearly visible.
