Preference is given to the use of terrareslin, natural pyrethrin.

The anthraquinone blue dye used in the present invention includes 1,4-dialkylaminoanthraquinone such as 1,4-diisopropylaminoanthraquinone and 1,4-dibutylaminoanthraquinone, and the azo yellow dye. Pyrazolone azo yellow dyes such as 3-methyl-1-phenyl-4- (phenylazo) pyrazol-5-ol are used.

The anthraquinone blue dye and the azo yellow dye are usually used in a weight ratio of 1:10 to 5: 1, preferably 1: 5 to 1: 1.

The electric mosquito repellent mat of the present invention comprises an active ingredient such as a pyrethroid compound, an anthraquinone blue dye and an azo yellow dye in a porous carrier such as a fibrous material such as a pulp board, cotton linter and polyester non-woven fabric or ceramics. It was retained, but further, dibutylhydroxytoluene, butylhydroxyanisole, dibutylhydroquinone, 2,2'-methylenebis (4-methyl-6-tert-butylphenol), 2,6-di-tert-butyl-4 -Methylphenol, octadecyl 3- (3,
5-di-tert-butyl-4-hydroxyphenyl) propionate, phosphorus-based antioxidant, sulfur-based antioxidant, HA
Antioxidants such as LS, piperonyl butoxide, cinepyrine 222, cinepyrine 500, synergists such as octachlorodipropyl ether, acid scavengers such as epoxidized soybean oil, stabilizers such as UV absorbers, esters (isopropyl myristate, Ethyl stearate,
Dibutyl adipate, dibutyl phthalate, etc.), fragrance, polybutene, etc. may be contained.

The mat for collecting electric mosquitoes according to the present invention is usually a solution prepared by dissolving an active ingredient, a dye, and, if necessary, an antioxidant, a synergist, a stabilizer, an ester, a fragrance, etc. in a solvent such as normal paraffin, isoparaffin, and naphthene. Is impregnated into a fibrous or porous carrier and dried.

[0010] The size of the electric mosquito collecting mat is generally
It has a size of 2.2 cm × 3.5 cm × 0.28 cm, and usually has an active ingredient of about 8 to 60 mg per mat, and a pigment of 0.1 to a combination of anthraquinone blue dye and azo yellow dye.
About 1 mg, and when using a fragrance, about 2 to 12 mg of fragrance is contained. In addition, as a whole solution (premix) in which active ingredients, pigments, etc. are dissolved, usually 50 to 200 per mat.
Contains about mg.

【Example】

Example 1 Praletrin 10.3% by weight, 2,2'-methylenebis (4-methyl-6-tert-butylphenol) 5.0% by weight, 1,
4-diisopropylaminoanthraquinone 0.1% by weight,
3-Methyl-1-phenyl-4- (phenylazo) pyrazol-5-ol 0.5% by weight, fragrance 5.0% by weight, isopropyl myristate 25.0% by weight and IP-2028 (Idemitsu Petroleum Co., Ltd. isoparaffin solvent) are mixed. The whole
100 mg of 100% by weight solution is 2.2 cm × 3.5 cm × 0.28 cm
Was impregnated with the fibrous carrier of Example 1 and dried to obtain a mat for electric mosquitoes.

Example 2 All were the same as Example 1 except that 0.2% by weight of 1,4-diisopropylaminoanthraquinone and 0.4% by weight of 3-methyl-1-phenyl-4- (phenylazo) pyrazol-5-ol were used. Then, an electric mosquito mat was obtained. Example 3 Electricity was the same as in Example 1 except that 0.3% by weight of 1,4-diisopropylaminoanthraquinone and 0.3% by weight of 3-methyl-1-phenyl-4- (phenylazo) pyrazol-5-ol were used. I got a mosquito mat.

Example 4 The electric mosquito repellent mats obtained in Examples 1, 2 and 3 were heated at 160 ° C. for 8 hours using a commercially available electric mosquito repellent, and the change in color tone was observed. As a result, the electric mosquito repellent mat obtained in Example 1 changes from yellow green to yellow, the electric mosquito repellent mat obtained in Example 2 changes from green to yellow, and the electric mosquito repellent mat obtained in Example 3 changes from green to blue. Each turned yellow-green. In addition, a volatilization test of praretrin, which is an active ingredient in the mat for electric mosquitoes obtained in Examples 1, 2 and 3, was conducted in a 70 m ³ glass chamber, and most of the praretrin in the mat was volatilized in 8 hours. confirmed.

[0014]

According to the electric mosquito-removing mat of the present invention, since the heated electric mosquito-removing mat causes clear discoloration, the presence or absence of an active ingredient can be easily determined.
