DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiment 1 Next, an embodiment of the present invention will be described.

The inventor of the present invention obtained a hint from plants that are hardly attached to insects, and as a result of various studies, produced a liquid pest repellent as follows. First, persimmon leaves 40-70 as plant material
%, 10% to 20% of a Japanese azalea, and 10% to 20% of a mugwort were pulverized so that the fermentation proceeds evenly so as to be 2 to 3 mm or less. The same weight of water was added thereto, and a total of 10 liters were put in a stainless steel tank and fermented at 30 to 40 ° C. for 3 years.
The resulting material was subjected to alcohol extraction with ethanol to obtain a plant extract having a pest repellent effect.

A porous ceramic which emits far-infrared rays and which is as porous as possible, has a high porosity (50% or more), and has a pore diameter of 1 μm or less is used as the plant extract.
mm, and immersed in one processed to a thickness of 20 mm. The pores of the porous ceramic are interconnected. The resulting samples were tested for mosquito repellent effect by a carbon dioxide attraction method (a method based on the habit of mosquitoes being attracted and gathered by the carbon dioxide emitted by humans and animals). Test equipment,
Release side desiccator (490mm × 460mm × 142
0mm) Attraction side desiccator (490mm × 460mm)
× 1420mm) is connected by a φ50mm vinyl hose, and an on-off valve is attached in the middle. Put 100 anopheles mosquitoes in the desiccator on the release side and fill the attracting desiccator with 50 ppm of carbon dioxide as an attractant. The above-mentioned porous ceramic, which is obtained by immersing a plant extract, 8 cc in a diameter of 35 mm and a thickness of 20 mm, is quickly set in an atmosphere of carbon dioxide gas of 50 ppm in an attraction side desiccator. Then, the effect is confirmed three times a day for three consecutive days to confirm the sustainability.
The carbon dioxide is replaced each time to prevent the effect of the plant extract evaporating between tests. The test results are shown in Table 1 below. The repellent effect of mosquitoes is indicated by the attraction inhibition rate (%). The method for producing porous ceramics is described in, for example, Japanese Patent Application Laid-Open No. 11-17 / 1999.
No. 1668 and Japanese Patent No. 2593740 describe those having a porosity of 89%. Further, as a method of manufacturing a porous ceramic having a far-infrared radiation function, for example, Japanese Patent Application Laid-Open No. Hei 7-291758 describes a method with a porosity of 76%.

[0014]

[Table 1]

According to Table 1, a sufficient repellent effect was confirmed in comparison with the comparative object (blank). The plant extract has the advantage that, unlike the resistant bacterium, the mosquito repellent effect becomes less accustomed to the mosquito repellent effect and the effect is less diminished because the material plant has been repellent to insects for many years. In the above, the experiment was carried out with Shimadara, but other Culex pipiens, Culex pipiens, Aedes albopictus, Culex pipiens and the like have similar effects, and fleas and ticks also have practically sufficient effects.

In addition, DEET 35%
The same effect is obtained by using an alcohol solution or a 1 to 3% solution of N, N-diethyltoluamide alcohol. The present mosquito repellent which is applied directly to the skin and used as long as the mosquito repellent does not smell these solutions directly The amount absorbed by humans and animals is small. In the case of these chemicals, the required amount is easily available at a low cost, and the effect has been proven. There is no problem if attention is paid to the amount of use, the period of use, the intended use, etc. according to the application.

Further, instead of porous ceramics as a liquid absorbing and dispersing agent, a superabsorbent (eg, a copolymer of polyacrylic acid and polyvinyl alcohol used in diapers and sanitary napkins) is added to the above plant extract, a 35% alcohol solution of DEET, N, The N-diethyltoluamide alcohol solution was absorbed and packaged with a nonwoven fabric.
These also had a similar effect.
