Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric mosquito repellent mat which can be used for a relatively long time of about 12 hours.

[0002]

2. Description of the Related Art An electric mosquito repellent mat is one in which an active ingredient such as a pyrethroid compound is held in a fibrous or porous carrier and is usually heated to about 140 to 180 ° C. and used for controlling pests such as mosquitoes. ing. The commercially available electric mosquito mat is blue before use, and it gradually fades to a pale blue color when heated, so that the presence or absence of the active ingredient can be determined.

[0003]

DISCLOSURE OF THE INVENTION The present invention provides an electric mosquito repellent mat in which the presence or absence of an active ingredient is easy to understand when using a mat for long-term use, that is, the end point of use is clarified to determine the effectiveness. The object was to provide a mat for electric mosquitoes that was made easier.

[0004]

The present invention provides an electric mosquito repellent mat containing diisononyl adipate (hereinafter referred to as the color tone adjusting agent) as a color tone adjusting agent. When the mat is used for a long time, the agent is used to adjust the change in color tone of the mat for electric mosquitoes that is suitable for heating and to facilitate the determination of the presence or absence of the active ingredient. Further, according to the present invention, since the present color tone adjusting agent easily dissolves the blue colorant, it is also preferable from the viewpoint of producing an electric mosquito repellent mat.

Next, test examples will be described. Test Example 1 The mats 1 to 8 of the present invention and the comparative mats 1 to 4 were heated at 160 to 170 ° C. using a commercially available electric mosquito catcher, respectively.
Changes in the color tone of the mat after 8 hours and after 12 hours were observed. As a result, the mats 1 to 8 of the present invention were light blue after 8 hours and almost white after 12 hours. In contrast, Comparative Mats 1 to 4 were almost white after 8 hours and 12 hours.

Test Example 2 Each of the mats 1 to 8 of the present invention was heated at 160 ° C. for 12 hours using a commercially available electric mosquito trap, and a volatilization test of the active ingredient in the mat was conducted. Even after 8 hours, about 60% of the active ingredient in the mat was 1%.
After 2 hours, it was confirmed that most of the active ingredient in the mat was volatilized. The measuring method is as follows.
Each of the mats of the present invention heated for 8 hours or 12 hours 1
The mixture was placed in a glass vial having a volume of 00 m, and 50 ml of acetone and a predetermined amount of benzyl n-butyl phthalate as an internal standard substance for quantitative analysis by gas chromatography were added. The vial was placed in an ultrasonic wave generation tank containing water and extracted by ultrasonic vibration for about 20 minutes. After the extract was concentrated under reduced pressure to approximately 5 ml-20 ml, it was effective by gas chromatography chromatography (detector: FID, separation column: 5% SE-30 (Φ3 mm, length 1.1 m), column temperature: around 190 ° C) The residual amounts of the components were measured. The same operation was performed on the unused mat of the present invention, and the volatilization amount was calculated from the difference between the two values.

Test Example 3 Each of the mats 9 to 18 of the present invention and each of the comparative mats 1 to 4 were subjected to 1 at 160 to 170 ° C. using a commercially available electric mosquito trap.
When heated for 2 hours and subjected to a volatilization test of the active ingredient in the mat, about 60% of the active ingredient in the mat was found to be effective after 8 hours and effective in the mat after 12 hours in any of the test mats. It is confirmed that most of the components volatilize.
The measuring method is in accordance with Test Example 2.
