Description

Thrips worm attractant composition {Attractants of Yellow Tea Trips}

The present invention relates to an attractant composition capable of attracting and trapping thrips, particularly thrips.

The thrips is an insect belonging to the order thrips and is a micropest that occurs year-round on all flowering crops such as horticulture and flowers and causes enormous damage. More than 5,500 species have been reported. ), Taiwan thrips (Frankliniella intonsa), thrips convex (Scirtothrips dorsalis), and thrips on mulberry trees (Thrips palmi) are known as economically important pests. Yellow flower thrips mainly occur on tomatoes, watermelons, melons, melons, cucumbers, pumpkins, green onions, garlic, radishes, red peppers, strawberries, roses, chrysanthemums, and carnations. When eaten, the leaves are atrophied due to deformity, and the flowers have speckled spots, which lowers the value of the product. In fruits, spots or cork are formed on the skin, causing the whole to become malformed. Taiwan thrips mainly occur on flowers such as chrysanthemums, roses, carnations, and lilies, and in some cases crop crops such as tomatoes, peppers, and cucumbers. In particular, the thrips worm is a peanut bud necrosis virus (PBNV), peanut chlorotic fan spot virus (PCFV), tomato spotted wilt virus (TSWV), etc. As an insect mediating virus, the host range is wide enough that more than 120 species of host plants have been reported, and it is designated as a major pest in Southeast Asia, India, Australia, the United States, and Japan. It has been reported to cause a lot of damage.

On the other hand, it is difficult to control using insecticides because of the strong proliferation and rapid development of resistance to chemical insecticides compared to other pests compared to other pests. Therefore, it is important to prevent damage to crops by pests in advance by foreseeing the appearance and timing of thrips, but in the case of thrips, the size of the thrips is very small compared to other thrips and it is difficult to observe with the naked eye. There are difficulties in collecting big data. Therefore, in order to collect big data on the thrips, a study to attract and capture the thrips should be preceded.

According to one non-limiting embodiment, the weight ratio of chiromone: additive included in the thrips worm attractant composition may be 1: 0.1 to 1.5, specifically 1: 0.1 to 1.2. However, in terms of maximizing the attracting effect of thrips worms and having improved durability, the weight ratio of chiromone included in the thrips attractant composition to the additive may be 1:0.1 to 0.6, but is not limited thereto.

According to one aspect of the present invention, the content of the thrips worm attractant composition (hereinafter referred to as the attractant composition) supported on the porous inorganic carrier in step b) is not particularly limited, but the total weight of the porous inorganic carrier and the attractant composition 10 to 70% by weight, specifically 20 to 70% by weight of the attractant composition may be included. When the attractant composition satisfies the above-mentioned range and is supported on the porous inorganic carrier, the porous inorganic carrier can sufficiently serve as the carrier while implementing the attracting effect against thrips.

At this time, the method for supporting the thrips worm attractant composition on the porous inorganic carrier is not limited, and any conventional method capable of supporting the solution on a porous solid may be used. As a non-limiting example, the supporting method may be a solution immersion method, but is not limited thereto.

As a non-limiting example, the above-mentioned porous inorganic carrier is a conventional porous inorganic material, and may be silica gel, alumina, polymer resin, carbon nanotube, mesoporous material, or a mixture thereof, but is not limited thereto. However, silica gel containing cobalt chloride (II) or methyl violet has a property of being blue and orange in a dry state, respectively, and changing color to pink and green when containing moisture. Therefore, when using the thrips attractant composition supported on silica gel, moisture in the air is deposited on the silica gel after a certain period of time and the color is changed by using the sustained-release lure support (the thrips attractant composition is Users can easily grasp the replacement time of the supported porous inorganic carrier).

On the other hand, when the attractant composition is supported on the porous inorganic carrier, the attractant composition is sensitive to acidity, and thus the porous inorganic carrier may be neutral. That is, the acidity (pH) of the porous inorganic carrier is preferably adjusted to pH 6-8, preferably pH 6-7. Accordingly, the porous inorganic carrier having an acidity or alkalinity is preferably neutralized using an acid or alkali aqueous solution or a buffer buffer solution.

According to one aspect of the present invention, the material of the UV blocking container in step c) suffices as long as it is made of a material that blocks UV, and preferably has one or more openings through which the attractant composition can be released, and the size of the sphere is not limited

As a non-limiting example, the above-described UV-blocking container is made of a polymer material selected from polyethylene (PE), polypropylene (PP), tetrafluoroethylene (PFA), polytetrafluoroethylene (PTFE), or a mixture thereof. may be used, but is not limited thereto.

According to another aspect of the present invention, the UV blocking container may be used by further coating an inorganic UV blocking agent on the outside of the container. Accordingly, the UV-blocking container can gradually release the molecules of the attractant composition into the air, so that the attracting period of the thrips can be maintained longer, the influence of light or air can be minimized, and the UV-blocking effect can be improved. By maximizing it, the effective period of the attractant composition can be maintained longer, so that the attracting effect of the thrips convex can be further maximized.

For example, the above-described inorganic sunscreen may be a mixture selected from titanium dioxide, zinc oxide, manganese oxide, zirconium dioxide, or cerium dioxide, but is not limited thereto.

In addition, the method for manufacturing a sustained-release lure for attracting thrips convex according to the present invention can be used by putting the attractant composition in a liquid state in a UV-blocking container. However, it is advantageous to use the porous carrier on which the attractant composition is supported in a UV-blocking container from the viewpoint of considering the management of the lure and the sustained release of the attractant composition.

According to an aspect of the present invention, the method for manufacturing a sustained-release luer for attracting thrips may further include attaching the sustained-release luer to the sticky member after step c). In detail, it may further include a sticky member as an attracting trap unit capable of capturing thrips convex attractant by the composition.

In one embodiment, the sticky member can be used without limitation as long as the adhesive is applied to the substrate, and regardless of the type of the adhesive and the substrate, it is sufficient as long as it can capture the thrips.

As a non-limiting example, the pressure-sensitive adhesive may include one or two or more components selected from styrene-isoprene-styrene block copolymer, hydrocarbon resin, paraffin oil, polybutene, antioxidant, cyclohexane and isohexane. In addition to this, it may further include grayton, hydrogenated resin, h resin, petroleum resin, sis resin and polyisobutylene. However, the present invention is not limited to the pressure-sensitive adhesive, and any component or compound capable of capturing insects by physical adhesion is sufficient.

As a non-limiting example, the substrate may be one or more selected from nonwoven fabric, synthetic resin film, synthetic resin sheet, biodegradable film, biodegradable sheet and biodegradable, but is not limited thereto.

(test evaluation)

The attraction test for convex thrips was the result of being conducted at an outdoor testing site around the Citrus Research Center in Seogwipo-si, Jeju Special Self-Governing Province from July 20, 2017 to December 17, 2019. In order to increase the accuracy of the experiment, 20 identical luers were prepared and used for each set, and a sticky trap was used as the trap. In this case, a sticky trap without using an attractant was used as a control.

Table 2 below shows the results of the attraction test for convex thrips. At this time, as shown, it can be seen that in Examples 1 to 21, the number of catches for thrips convex, Hawaiian thrips and yellow flower thrips is significantly superior to those of Comparative Examples. In particular, in the case of Example 6, in which the combination agent was additionally added, it was confirmed that the attracting effect against convex thrips was the most outstanding.
