[Means for Solving the Problems]
The present invention was made to find a highly active cockroach repellent and a cockroach repellent method, and contains a cockroach repellent containing 2- {1-methyl-1- (4-methylcyclohexyl) ethoxy} ethanol, Use of 2- {1-methyl-1- (4-methylcyclohexyl) ethoxy} ethanol for cockroach repellency and retention of 2- {1-methyl-1- (4-methylcyclohexyl) ethoxy} ethanol The present invention provides a method for avoiding cockroaches characterized in that a seat is installed indoors.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
2- {1-methyl-1- (4-methylcyclohexyl) ethoxy} ethanol (hereinafter referred to as the present compound) used in the present invention is a compound represented by the formula (1).

[0007]
This compound is produced by further hydrogenating 2- {1-methyl-1- (4-methyl-3-cyclohexenyl) ethoxy} ethanol obtained by reacting α-pinene and ethylene glycol. Can do.
[0008]
Although the present compound itself may be sufficient as the cockroach repellent of this invention, the form by which this compound is normally hold | maintained at the suitable support | carrier, for example, the sheet | seat by which this compound is hold | maintained, is mentioned. It is also possible to take the form of a kneaded preparation into a resin, an emulsion, an oil, a wettable powder, a flowable preparation, a granule, a powder, an aerosol preparation, a heat transpiration agent, and the like.
[0009]
When the cockroach repellent of the present invention takes the form of a sheet in which the present compound is retained, the material of the sheet is not particularly limited, and for example, paper (filter paper, etc.), synthetic resin (polyethylene, polypropylene, etc.), and Cloth (nonwoven fabric etc.) is mentioned. The amount of the present compound held in the sheet is usually about 0.0005 to 20 g, preferably about 0.001 to 10 g per 1 m ² .
[0010]
When the cockroach repellent of the present invention takes a preparation form such as an emulsion or an oil, the amount of the present compound in the preparation is usually about 0.01 to 10% by weight.
[0011]
The cockroach repellent of this invention is used by processing in the place which wants to prevent the invasion of a cockroach, or the place which wants to prevent the invasion of a cockroach, for example, a general house, a warehouse, a dining room, etc. That is, the cockroach repellent of the present invention can be applied by means such as spraying, spraying, applying, placing or sticking depending on the formulation form, and the cockroach repellent of the present invention can be applied to materials such as furniture members.

[0012]
The cockroach repellent of the present invention is effective in repelling various cockroaches such as German cockroaches, black cockroaches, American cockroaches, flying cockroaches, and cockroach cockroaches.
[0013]
【Example】
Hereinafter, the present invention will be described in more detail with reference to production examples and test examples, but the present invention is not limited to these examples.
[0014]
First, a manufacture example is shown about manufacture of the cockroach repellent of this invention.
Production Example 1
10 ml of an ethanol solution (1% by weight) of this compound is applied to 1 m ² of a nonwoven fabric and dried to obtain a sheet-like cockroach repellent of the present invention.
[0015]
Production Example 2
10 ml of an acetone solution (1% by weight) of this compound is applied to 1 m ² of filter paper and dried to obtain a sheet-like cockroach repellent of the present invention.
[0016]
Production Example 3
A mixture of 1 g of the present compound and 19 g of ethanol is placed in an aerosol can, and after an aerosol valve is mounted, 80 g of dimethyl ether is filled from the aerosol valve to obtain the cockroach repellent of the present invention of aerosol.
[0017]
Next, the cockroach repellent activity of the cockroach repellent of the present invention is shown in Test Examples.
Test Example Applying 1.0 ml of acetone containing the present compound at a predetermined concentration to a filter paper of 6 cm × 9 cm, and bending a cockroach repellent (sheet preparation) obtained by drying, a triangle with a side of 3 cm is defined as the base A cylindrical triangular prism was used. In addition, a cockroach repellent (sheet preparation) obtained by applying 1.0 ml of acetone to 6 cm × 9 cm filter paper and drying was folded to form a cylindrical triangular prism having a triangle with a side of 3 cm as the base.
Put two of the above triangular prisms into a plastic container with a bottom of 38cm x 25cm and a height of 7cm to make a shelter (hiding place for cockroaches), and then add 20 adult German cockroaches (10 males and 10 females) with food and water. After 8 days, the place where the cockroach was observed was observed (2 repetitions).
In addition, it replaced with this compound as a comparison control, and tested similarly using (alpha) -terpineol (compound shown by Formula (2)).

The results are shown in Table 1.
[0018]
[Table 1]

In the table, A represents the number of cockroaches hidden in the shelter not treated with the drug, B represents the number of cockroaches hidden in the shelter treated with the drug, and C represents the number of cockroaches outside the shelter.
[0019]
From Table 1, it can be seen that the shelter treated with α-terpineol shows little change in the number of cockroaches hidden compared to the untreated shelter, whereas the shelter treated with this compound shows almost no cockroaches hidden. Understand.
[0020]
【The invention's effect】
The cockroach repellent of this invention shows the outstanding cockroach repellent effect.
