[Solution] The adhesive trap 6 comprises an adhesive sheet 2 and a rod 1, wherein the adhesive sheet has an adhesive portion 3 and a non-adhesive portion 4, and the non-adhesive portion has at least two independent openings 5, and the rod holds the adhesive sheet through the openings so that the adhesive sheet can be moved to any position along the length of the rod.

Description

Technical Field

[0001] The present invention relates to an adhesive trap for adhesively capturing walking agricultural pests.

Background Art

[0002] Among agricultural pests, spider mites have increasingly developed high drug resistance in recent years, making it difficult to control them with chemical pesticides. Therefore, natural enemy pesticides using predatory mites, which are natural enemies, and stoma sealants are also being used. Spider mites have strong leg strength, and there has been a problem that they are difficult to capture with conventional adhesive traps. However, as in Patent Document 1, a walking agricultural pest capture device has been proposed that utilizes the characteristics of spider mites to capture the abdomen of spider mites with an adhesive pointed part.

Summary of the Invention

Problems to be Solved by the Invention

[0004] However, when the adhesive trap as in Patent Document 1 is installed on the ground at the initial stage of installation, there is a problem that the capture efficiency of spider mites gradually decreases as the crop grows. This is due to the nature of spider mites to climb up and reach the highest point. In the early stage of crop growth, the adhesive trap is located higher than the crop, so spider mites are captured by the adhesive pointed part as they move towards the highest point of the adhesive trap. However, as the crop grows, the adhesive trap comes to be located below the leaves of the crop, making it difficult for spider mites to reach the adhesive pointed part of the adhesive trap.

[0005] Therefore, this invention has been made in view of the aforementioned problems, and aims to provide an adhesive trap that can be installed in an appropriate location according to the growth of the crop to capture crawling agricultural pests, thereby maintaining a high efficiency in capturing crawling agricultural pests over a long growing season. [Means for solving the problem]

[0006] The inventors of this invention have diligently studied and developed this invention to solve the above-mentioned problems. Specifically, this invention provides the following preferred embodiments. [Aspect 1] Includes adhesive sheet and rod, The aforementioned adhesive sheet has an adhesive portion and a non-adhesive portion. The non-adhesive portion has at least two independent openings, An adhesive trap characterized in that the rod holds the adhesive sheet through the opening so that the adhesive sheet can be moved to any position along the length of the rod. [Aspect 2] The adhesive trap according to embodiment 1, characterized in that the opening is substantially circular. [Aspect 3] The adhesive trap according to embodiment 1 or 2, characterized in that the rod is a cylinder with a substantially circular cross-section. [Effects of the Invention]

[0007] This invention provides an adhesive trap that captures crawling agricultural pests by being installed in appropriate locations according to the growth of the crop, thereby maintaining a high efficiency in capturing crawling agricultural pests over a long growing season.

[Figure 7] This is a schematic diagram of an adhesive trap with an adjusted installation height of the adhesive sheet, according to one embodiment of the present invention. [Modes for carrying out the invention]

[0009] The embodiments of the present invention will be described in detail below, but the scope of the present invention is not limited to the embodiments described herein, and various modifications can be made without departing from the spirit of the present invention.

[0010] The adhesive trap of this invention has an adhesive sheet having an adhesive portion and a non-adhesive portion, and at least two independent openings are provided in the non-adhesive portion. By passing a rod through these openings, the adhesive sheet can be moved to any position along the length of the rod to determine its position, and the installation height of the adhesive sheet can be adjusted. By using the sticky trap of this invention as described above, the sticky part of the sticky trap can be easily adjusted to be positioned slightly above the leaves of the crop in accordance with the growth of the crop, taking advantage of the spider mite's tendency to climb upwards to reach the highest point. This allows for maintaining a high efficiency in capturing crawling agricultural pests over a long growing season.

[0011] <Adhesive sheet> The adhesive sheet constituting the adhesive trap of the present invention can be widely used as long as it can be attached to the rod of the present invention. For example, Pulutrap (registered trademark) -9 manufactured by Kuraray Trading Co., Ltd. on the market can be mentioned. The adhesive sheet has an adhesive part and a non-adhesive part. By having an adhesive part and a non-adhesive part, walking agricultural pests climbing up from the ground along the rod reach the non-adhesive part and further move to the adhesive part, making it easier to be captured.

[0012] <Opening> By having at least two independent openings in the non-adhesive part, the adhesive sheet can be held through the rod, and furthermore, the adhesive sheet can be moved to a free position in the length direction of the rod. The openings formed in the non-adhesive part of the adhesive sheet may be punched into shapes such as a substantially square shape (including those with rounded corners or diagonal corners) or a substantially circular shape (including an elliptical shape), or may be cuts. If the opening formed in the non-adhesive part of the adhesive sheet is substantially circular, it is preferable because it is easy to pass the rod through and the adhesive sheet is not easily torn. It is preferable that there are two openings formed in the non-adhesive part of the adhesive sheet in order to maintain the strength of the adhesive sheet. The openings formed in the non-adhesive part of the adhesive sheet are preferably arranged in a position and orientation that are easy to pass the rod through.

[0013] <Rod> The length of the rod of the present invention is preferably 300 to 2000 mm. Thereby, it can be installed from the low height state immediately after transplantation, and even when the height grows relatively high like tomatoes and beans, the position can be adjusted accordingly. The rod of the present invention preferably has a uniform diameter. This makes it easy to adjust the position by sliding the adhesive sheet. The diameter of the rod of the present invention is preferably 2.0 to 5.0 mm so that it can easily pass through the holes of the adhesive sheet and can be held at a specified position. The rod of the present invention is preferably a cylinder having a substantially circular cross-section (including an elliptical shape). This makes it easier to pass the rod through the opening of the adhesive sheet and reduces damage to the adhesive sheet during operation.

[0014] <Material of the rod> The rod of the present invention is preferably at least one selected from the group consisting of wood, wood plastic, plant fiber composite plastic, biodegradable plastic, and biomass-derived plastic. The rod is preferably formed of a material having appropriate flexibility and rigidity, such as these materials. Thereby, the adhesive trap can be stabbed into the ground and made to stand on its own.
