Abstract

PROBLEM TO BE SOLVED: To provide a noxious insect trap of simple structure, which generates luring colored light characteristic of an insect type using natural light, and traps the insects by an adhesive. SOLUTION: This noxious insect trap contains a colored sheet 1 which reflects or transmits two or more types of luring colored light, and adhesive layer which is attached to, or set near, the colored sheet 1. The adhesive layer traps the insects lured by light reflected by, or transmitting through, the colored sheet 1 irradiated with natural light. The colored sheet 1 reflecting or transmitting two or more types of luring light comprises a paper or transparent sheet as the base, printed with two or more luring colors in mosaic or band pattern. The adhesive layer is formed on one side of the colored sheet 1 in such a way that it is exposed when the trap is in use.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pest trapping apparatus utilizing attracting light for attracting and trapping harmful insects in greenhouses such as greenhouses with attracting light peculiar to the harmful insects.

[0002]

2. Description of the Related Art It has long been known that many pests are attracted by light containing a specific wavelength component. For example, whitefly, whitefly, aphid, etc. are attracted by yellow light. Therefore, a discharge lamp such as a fluorescent lamp (JP-A-8-47361), an incandescent lamp, a light-emitting diode (JP-A-6-54635), etc., directly or with their light sources and reflection that gives a change in their spectral distribution. Alternatively, a device has been proposed and implemented in which a permeation light is generated by combining a transmission filter and the attracted pests are captured with an adhesive tape or the like.

However, those that actively use a light source are often large in size because it is necessary to accurately maintain the arrangement of the light source and the positional relationship between the light source and the filters, reflectors, adhesive tapes, and the like. Although various types such as a stationary type and a hanging type have been implemented, it is not easy to properly arrange these in a greenhouse or the like so as not to disturb the crops.

No particular mention is made of a light source, but in Japanese Utility Model Publication No. 62-16838, an adhesive tape for agricultural use for attracting insects, the average reflectance and average transmittance of ultraviolet rays having a wavelength of 400 nm or less are respectively visible rays. Has proposed an agricultural adhesive tape for collecting insect attracting pigments, which is less than 30% of the average reflectance. According to the example, the adhesive layers are formed on both sides. With this tape,
Reflected light and transmitted light are colored. It is explained that the desired properties can be obtained by changing the compounding amounts of the yellow agent, the blue agent, the red agent, the white agent and the infrared absorbing agent in order to obtain an arbitrary color.

SUMMARY OF THE INVENTION It is an object of the present invention to utilize a characteristic of insects to be attracted by color to trap the collected insects with an adhesive material. The insect attracting color differs depending on the species of insects, so a pest trapping device that can attract and trap insects of different species by combining two or more colors of different species of insects on the same surface is provided. To do.

[0006]

In order to achieve the above object, the pest trapping apparatus according to the present invention is an apparatus for generating an attractive colored light peculiar to a pest and trapping it using an adhesive,
A colored sheet that reflects or transmits at least two attracting colored lights and an adhesive layer that is arranged integrally with or in close proximity to the sheet, and is attracted by the light reflected or transmitted by irradiating the colored sheet with natural light. It is configured to trap pests with the adhesive layer. In the pest trapping device, the coloring sheet that reflects or transmits the two or more attracting colored lights is formed by printing two types of attracting colors on a paper or a transparent sheet in a mosaic shape or a band shape, and forming an adhesive layer on one surface thereof. In this case, the adhesive layer can be used so that it appears on the surface. In the pest trapping apparatus, when the sheet is rolled up and housed in a cylindrical container having a slit, an arbitrary length can be pulled out and suspended at the sheet end. In the pest trapping device, the pressure-sensitive adhesive sheet is arranged so that the pressure-sensitive adhesive surface faces downward on the bottom of a frame having an edge on the bottom side and arranged substantially horizontally, and a transmission type color filter surface is arranged on the upper surface of the frame. Can be arranged and used.
