Example 1
As shown in FIG. 1, a yellow coating layer is formed as an attracting color on milk carton paper as a base material, a polybden adhesive is applied to a thickness of 70 μm as an adhesive layer, and a release paper is pasted together The adhesive sheet of 10 cm × 25 cm is made horizontally long, and the holding part and the attaching part are made of polystyrene foam and formed by integral molding. One end of the adhesive sheet is grounded to the holding part via the attaching part. A hollow color pole (thickness: 0.8 cm, length: 10, 20, length) pierced into the ground on the ceiling wall of the intermediate hole (inner diameter: 1.0 cm) of the holding part. A pest trap of Example 1 was obtained by being supported by a support column of 30 cm, made of polyvinyl chloride, so as to be rotatable and detachable. The obtained pest trap was installed in a green pepper field in Hiratsuka City in early July, and the capture performance was tested. As the pressure-sensitive adhesive sheet used, a blue sheet (hue: 3.0 PB, lightness: 5.4, saturation: 10.6) having the same size and thickness was used. In consideration of the rotational distance of the attached adhesive sheet, the installation place of the insect trap is installed 30cm away from the bell pepper, and the installation height of the adhesive sheet is 10cm, 20cm and 30cm from the ground, respectively. Table 1 shows the number of traps (animals) of the pests (Hills thrips and Citrus thrips) according to the time of installation (10, 20, 30, 40, and 50 days).

(Comparative Example 1)
As Comparative Example 1, the same adhesive sheet as used in Example 1 was used as an adhesive sheet, and a 0.7 cm diameter hole was formed above and below the adhesive sheet in the short direction. Example 1 was used except that a trap with the same strut inserted as used was used and this trap was pierced into the ground. Table 1 shows the number of captured pests (Hirazuhana thrips and Citrus thrips).

  As can be seen from Table 1, in the case of Comparative Example 1, dirt, sand, dust, etc. adhere to the adhesive surface from about 20 days after installation, regardless of the installation height, and about 2/3 of the adhesive surface. Covering and losing the part where the pests were attached, the capture performance was degraded. In the case of Example 1, the contamination by dirt, sand dust, dust, etc. is very small even after 50 days, the stickiness is maintained, and the capture performance is maintained. In the case of Example 1, the contamination by dirt, sand dust, dust, etc. is very small because it has the above-described configuration, so that the adhesive sheet does not oppose the wind flow and is parallel to the wind flow. It is considered that dirt, sand dust, dust, etc. flow without touching the adhesive surface.

(Example 2)
In Example 1, it was carried out similarly to Example 1 except having made the adhesive sheet vertically long and having one end gripped by the attaching part via the holding part. Table 2 shows the number of captured pests (Hirazuhana thrips and Citrus thrips).

(Comparative Example 2)
As Comparative Example 2, the same adhesive sheet as used in Example 1 was used as an adhesive sheet, and 0.7 cm diameter round holes were formed above and below the longitudinal direction of the adhesive sheet. The same trap as that used in Example 1 was used except that this trap was inserted into the ground. Table 2 shows the number of captured pests (Hirazuhana thrips and Citrus thrips).

  From Table 2, the same results as in Table 1 were obtained. From Table 1 and Table 2, when the pest trap according to Examples 1 and 2 is used in a field where dust, sand dust, dust, etc. are swept up by an air current such as wind, the pest trapping performance by the adhesive sheet is extended over a long period of time. It can be maintained and is easy to use.
