The present invention will now be described in detail with reference to the embodiments of the present invention shown in the accompanying drawings. In the insect attracting method and device according to the present invention, a long afterglow fluorescent substance manufactured by Nemoto Special Chemical Co., Ltd. is used as the fluorescent substance. This fluorescent material is SrAl
FIG. 1 shows the characteristics of a strontium-aluminum oxide-based phosphor having a composition of ₂ O ₄ .

As shown in the figure, the present phosphor has a long afterglow time and a high afterglow brightness. Moreover, it has excellent light resistance.
For example, the afterglow brightness is 300 mcd or more per unit area (D65, irradiation under 200 lux for 4 minutes and brightness after 20 minutes), which is higher than that of a conventional zinc sulfide-based phosphor.
There is about 15 times the brightness.

Afterglow time (0.32 per unit area)
The decay time to mcd) is 2000 minutes or more, and the afterglow time is about 10 times longer than that of a conventional zinc sulfide-based phosphor. The light resistance (the time until the afterglow brightness decreases by 20% or more when accelerated by a 300 W high-pressure mercury lamp) is 1000 hours or more, which is about 100 times that of conventional zinc sulfide-based phosphors. Is equipped with.

Ultraviolet light having a wavelength of about 360 nanometers is the most efficient excitation light, but since the excitation light has a wide wavelength range (200 to 450 nanometers), sunlight, mercury lamps, fluorescent lamps, and others are used. Various light sources can be used as excitation light. As described above, since radiation is not required for excitation, it is safe and easy to handle. Moreover, since such radioactive substances and other harmful substances are not contained, the waste can be treated as normal waste and the disposal cost is low. Also, the stronger the light that is applied, the greater the luminous intensity. Furthermore, since it has excellent light resistance and weather resistance and high chemical stability as described above, it is suitable for outdoor use.

In the method of attracting insects according to the present invention, insects are attracted using the fluorescent substance formed containing at least SrAl ₂ O ₄ as described above. That is, by exposing such a fluorescent substance to the outdoor or indoor environment as a light emitting state,

I'm using one.

This insect attractant was attached to the insect attracting device shown in FIG. 2, and an adhesive plate was attached to the lower part as an insect trap. This insect attracting device is installed at a height of about 1 meter above the rough ground at 13 test sites, and the test period is from 10:00 am on November 26 to 7:00 pm on November 27. The number of trapped insects counted at each point is shown in FIG.

In the figure, the total number of insects captured by the adhesive material is 68 in total, and the breakdown is 58 belonging to Coleoptera 4, Lepidoptera 2, Diptera, Hymenoptera, Hemiptera 58, and other 4 It was an individual. For the test under the strong wind of light rain on the day,
The number of trapped insects varies depending on the installation location, and compared to other locations, the number of trapped insects at each of the locations 9, 10, 11, 12 installed in a place free from wind is higher. The types of trapped insects were mostly small insects belonging to the order Hemiptera, such as planthoppers and leaf flies. In addition, it has been observed that many small hemiptera insects gather on the insect attractant plate placed directly on the ground.

FIG. 4 shows a comparison with the result of capturing with an adhesive plate using another rough land at the same test site as a control point. As is clear from the figure, compared to the control point,
At the test site where the insect attractant plate is used, it is possible to confirm a considerable insecticidal property.

Next, the results of the housefly attraction test will be described. This attracting test is carried out by sandwiching a glass plate between two wall surfaces (height: 2 meters) in a test chamber 20 of about 20 meters as shown in FIG.
22 is attached. An adhesive material is thinly applied to the exposed surface side of the glass plate. Further, similarly processed A4 size papers 23 and 24 are installed at two places. 100 houseflies adults in this test room 20
The individual was released, and the number of attached individuals was counted after 24 hours. The results are shown in FIG. As shown in the figure, the attractant body 2
A clear attracting effect of 1 and 22 can be confirmed.
