JP2000125746A - Preparation of insect-proofing light source - Google Patents

Abstract

PROBLEM TO BE SOLVED: To obtain light source having a maximum radiation peak in a specific wavelength and controlling insects such as owlet moths or stink bugs which are insect pests of farm products such as vegetables or fruit trees. SOLUTION: This light source for insect-proofing has a maximum radiating peak wavelength near 0.545 μm wavelength. In the light source, a coating material containing imidazolone pigment is preferably applied to an arc tube or its external ball. Preparation of insect-proof light source capable of corresponding to various insects is made possible by using same arc tube by changing the content of imidazolone pigment.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a light source for controlling insects such as night moths and stink bugs which are pests of agricultural products such as vegetables and fruit trees.

[0002]

2. Description of the Related Art As night moths, night moths include Akebiko noha and Akaeguriba, which absorb mature fruits of fruit trees. , Acacia catechu, Giant tobacco, Awanomeiga and the like.

As a method for preventing crop damage to these night moths, there is a method utilizing phototaxis, and typical light sources include a blue fluorescent lamp and a yellow fluorescent lamp. A blue fluorescent lamp emits light in a wavelength range of 0.30 μm to 0.55 μm, and its maximum emission peak is around 0.43 μm, and generally causes an attracting action.

[0004] Yellow fluorescent lamps are 0.50 µm to 0.70 µm.
m, and the maximum emission peak is 0.585.
The phosphor has a main emission peak wavelength around 0.585 μm, and light in a short wavelength range of 0.50 μm or less is blocked by a pigment containing titanium yellow. The mechanism of yellow insect repellent is repelling or suppressing behavior of night moths by optimizing the compound eyes, and it is said that the necessary illuminance is about 1 lux or more.

[0005] When using a blue fluorescent lamp, it is necessary to catch flying insects. However, since it is very difficult, a yellow fluorescent lamp is more effective as a light source for insect control.

[0006]

The radiation wavelength range in which insects repel or attract insects differs depending on the type. For example, in the same night moth, the armyworm is 0.4
Tobacco moth at 3 μm acts to repel radiation in a wavelength range of 0.53 μm or more, and takes an attractive action in a short wavelength range below that.

[0007] However, any insect exhibiting phototaxis is 0.5
It is said that emitted light in a long wavelength region near 0 μm or more exhibits behavior suppression or repelling behavior, and a conventional yellow fluorescent lamp is manufactured based on it.

[0008] The conventional yellow fluorescent lamp emits a small amount of radiation, and the number of installed lamps must be increased in order to maintain the minimum illuminance for insect control.

An object of the present invention is to solve the above-mentioned problems and to provide an insect repellent light source having a higher radiated light amount.

[0010]

In order to achieve the above object, the method of the present invention provides efficient radiation on the long wavelength side of about 0.50 μm or more and cutoff on the short wavelength side of about 0.50 μm or less. It is characterized in that a mixture of a paint using an imidazolone pigment and a clear at an appropriate ratio is applied to an arc tube or its outer sphere.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below. The insect-controlling light source blocks a wavelength range of about 0.50 μm or less, and efficiently transmits a wavelength range longer than 0.50 μm.

Benzimidazolone, clear, hardener,
The thinner is mixed at a ratio of 6: 5: 5: 13 and applied to a glass tube of a white fluorescent lamp (color temperature: 4,200K). Here, by changing the ratio of the clear, the short wavelength side of the emitted light can be easily changed from 0.45 μm to 0.53 μm.

FIG. 1 shows the spectral distribution characteristics of the insect-controlling fluorescent lamp according to the present invention. This fluorescent lamp has a maximum emission peak near 0.545 μm, and has an illuminance approximately 1.3 times that of a conventional yellow fluorescent lamp.

[0014]

As described above, according to the present invention, it is possible to cope with various insects with the same arc tube by producing a more effective light source than the conventional yellow fluorescent lamp and changing the content of the imidazolone pigment. Simple production of an insect repelling light source is possible.
