2. Description of the Related Art Conventionally, (1) mosquito coils and (2) electric mosquito mats have been favored as methods for heating and evaporating insecticidal components for the purpose of insect killing. A method of immersing a liquid-absorbing wick in a chemical solution and heating the upper portion of the wick to heat and evaporate the chemical solution has also been widely used. Among them, the electric mosquito collecting mat is a fibrous mat impregnated with insecticidal components.
It is placed on a heat radiating plate of substantially the same shape as the mat of the heating and transpiration device, and heated by energization to evaporate the insecticidal component,
The vorticity at the center of the heat sink is set in the range of 140 to 180 ° C. The electric mosquito mat is an easy-to-use preparation, but the entire bottom of the mat is heated by the heat sink,
Even if the volatilization modifier is added, the volatilization amount of the insecticidal component decreases with time. For this reason, a single mat is usually designed to replace the mat every day and contains only the pyrethroid-based insecticide used for one day, and it is difficult to develop a long-term insecticide mat due to the characteristics of the formulation. Has been considered. On the other hand, in the case of liquid mosquito collection, the same pyrethroid-based insecticidal ingredients are used as in the case of electric mosquito collection mats. I have. This method is convenient because the effect lasts for 30 to 60 days just by installing the chemical bottle once, but the fear of liquid leakage is inevitable.

[0008] In the present invention, the pyrethroid insecticidal component is blended in a fibrous mat in an amount of 50 mg or more per sheet. When the amount is less than 50 mg, the insecticidal effect cannot be exerted for a long period. When the fiber mat is impregnated, a stock solution containing a pyrethroid-based insecticidal component and, where necessary, a stabilizer for the insecticide component, a volatilization regulator, a solvent, a fragrance, a dye, and the like are used as needed.
However, since there is a limit to the maximum amount of retentate of the mat, for example, in the case of a mat having a size of 22 × 35 mm and a thickness of 2.8 mm, it is appropriate to suppress the stock solution to within 1.2 g per sheet. is there.

[0010] The present invention relates to a heating and evaporating apparatus having the specific mat and a heat radiating plate having an area 0.2 to 0.6 times the bottom area of the mat and having a heating temperature of 70 to 170 ° C. The feature is that they are combined. The mechanism by which the transpiration of the insecticidal component from the mat is kept constant is considered as follows. First, when electricity is supplied, the insecticidal component evaporates from the mat located on the heat sink, but since the area of the heat sink is reduced to 0.2 to 0.6 times the bottom area of the mat, the initial evaporation amount is It is not too high like a product. Thereafter, when the power supply is stopped, the insecticidal component of the mat portion located on the non-heated portion moves to the mat on the heat sink so that the concentration gradient of the generated insecticidal component becomes equilibrium. Thus, the desired amount of the insecticidal component is always supplied to the mat on the heat sink,
Unlike the conventional products, the amount of transpiration with the passage of time during the day is almost constant, and the transpiration can be continued for a long period of 5 days or more. The occupied portion of the heat radiating plate on the bottom surface of the mat may be the center portion or the side portion of the mat, but is preferably the center portion of the mat in order to obtain more stable performance.

Embodiment 1 FIG. On a fibrous mat having a size of 22 × 35 mm and a thickness of 2.8 mm, 300 mg of d-trans-aresulin (trade name: Esbiothrine) and 200 m of piperonyl butoxide as a volatilization modifier were used.
g, 10 mg of a stabilizer, a trace amount of a perfume and a matting stock solution containing a blue dye were impregnated. When the mat was placed and used in a heating and evaporating apparatus having a circular heat radiating plate having a diameter of 16 mm and a heat generation temperature of 150 ° C. in the center and supporting the mat in four places around the heat radiating plate, The amount of d-trans-aresulin evaporated per 12 hours was about 30 mg. This mat exhibited stable transpiration performance and insecticidal efficacy over 10 days, and was excellent in usability without fear of liquid leakage.

A kerosene solution containing 0 mg, 20 mg of stabilizer and a trace amount of blue dye was impregnated. As the heating and evaporating device, a device having a band-shaped heat radiating plate arranged at the center having an area 0.5 times the mat bottom area was used, and a cycle in which electricity was supplied for 12 hours at night and stopped during the day was continued for 10 days. As a result, the amount of transpiration of d-cis and trans-framethrin was about 20 mg every day, which was stable over time, showing a sufficient mosquito control effect for 10 days.

Test Example 1 Insecticidal mats shown in Table 1 were prepared according to Examples 1 and 2, and loaded into various heat evaporation devices to perform various performance tests. (1) Transpiration performance: The transpired insecticidal components were trapped by a silica gel packed column at predetermined time intervals, and the insecticidal components were extracted with acetone and analyzed by gaz chromatography to determine the amount of transpiring per hour of the insecticidal components. The values shown in Table 1 are shown as relative ratios when the initial value of each preparation is 1.00. (2) Insecticidal efficacy: The erecting effect on Culex pipiens was evaluated by the following continuous aeration method at predetermined time intervals. The values shown in Table 1 are shown as relative effective ratios when the initial value of a daily mat containing 40 mg of d1, d-cis and trans-arrestrin is 1.00.
