Firstly, radius [r (cm) ] , length [L (cm) ] and weight 25 [go (g) ] of the liquid-absorbing wick are measured. Then 24 the liquid-absorbing wick puts in the beaker charged with water, and the liquid-absorbing wick is dipped into water completely and leaves it to stand for 6 hours at a room temperature. The liquid-absorbing wick is removed and some 5 extra water around the liquid-absorbing wick is wiped with paper waste and then the weight of the liquid-absorbing wick [g, (g)] is measured and the porosity is calculated according to the following equation. void fraction(%)= X 100 ,rr 2 L 10 go; dry weight of the liquid-absorbing wick (g) gy; weight of the liquid-absorbing wick after absorbing water (g) p ; density of pure water (g/cm 3 ) = 1 r; radius of the liquid-absorbing wick (cm) 15 L; length of the liquid-absorbing wick (cm) Though various liquid-absorbing wicks can be prepared by selecting a constitution of the liquid-absorbing wick, a particle size of starting material or a manufacturing condition adequately, the porosity of the liquid-absorbing 20 wick used herein is usually from 20% to 60%, and preferably from 20% to 50%. [0029] The pesticidal material for heat transpiration of the present invention is characterized by satisfying the 25 following equation Equation: 0.17 < a/b < 2.5, wherein the "a" represents the glycol ether content (wt%) in the composition and the "b" represents the porosity (%) 5 of the wick. Satisfaction of the equation enables to vaporize the pesticidal composition stably for a long period and then provide the stable pesticidal activity. Also, it is preferably 0.25 < a/b < 2.0, and more preferably 0.28 < a/b < 1.5. Alternatively, it is 10 preferably 0.2 < a/b < 2.5, more preferably 0.2 < a/b < 2.5, even more preferably 0.5 < a/b < 1.6, and particularly preferably 0.7 < a/b < 1.3. In these cases, the pesticidal active ingredient can vaporize stably. [0030] 15 [A liquid-absorbing type of apparatus for controlling pests by heat transpiration] The liquid-absorbing type apparatus for controlling pests by heat transpiration has the pesticidal material for heat transipration of the present invention, which 20 apparatus is equipped with a chemical bottle that is charged with the present composition, the liquid-absorbing wick that is set up so as to be dipped into the composition, and a heater for heating a part of the wick. Herein, the "liquid-absorbing type apparatus for 25 controlling pests by heat transpiration" refers to an 26 apparatus which can cause, by heat, transpiration of a liquid pest-controlling composition absorbed into a carrier such as a porous wick to thereby control pests. In the apparatus of the present invention, both 5 liquid-absorbing wick and the present composition constitute the present material of the apparatus. A specific example of the liquid-absorbing type apparatus for controlling by heat transpiration of the present invention is explained with attaching drawings. 10 [0031] Figure 1 is a schematic drawing of the liquid absorbing type of apparatus for controlling pests by heat transpiration. This apparatus is equipped with a chemical bottle 4 that is charged with the present composition 1, a 15 liquid-absorbing wick 3 and a heater 2 for heating a partial of the wick. As the heater to be used herein, the heat generator that induces heating by energization is usually used and the kind or the shape of the heat generator is not particularly limited. The heater includes 20 a PTC heater and the others. The liquid-absorbing wick 3 is inserted into the chemical bottle 4 in a manner that one end part of the wick is dipped into the present composition 1 in the chemical bottle 4. The other end part of the liquid-absorbing wick 25 3 is projected from the chemical bottle 4, and the 27 environment of its overhead is surrounded by a ring-shaped heater 2. Also the above-mentioned ring-shaped heater is connected to a cord to energize and induce heating. [0032] 5 The liquid-absorbing wick 3 is preferably set up so as to place its end part at about 1 to about 1.5 mm forward from the internal bottom surface of the chemical bottle 4. It is preferable that the interval between the above mentioned ring-shaped heater 2 and the liquid-absorbing 10 wick 3 is usually a range of from 0.5 to 2 mm, and the heating temperature of this ring-shaped heater is 150 0 C or less. Alternatively, the heating temperature is preferably 150 0 C or less, more preferably from 40 0 C to 150 0 C and even more preferably from 90 0 C to 150 0 C. 15 [0033] The liquid absorbing wick 3 is usually set up so as to place its lower end part at about 1 to 5 mm forward from the internal bottom surface of the chemical bottle 4. [0034] 20 The quality of material of the chemical bottle 4 is particularly limited unless the present composition is leaked out or oozed out after the passage of a long period, but is preferably a clear material that can be confirmed the residual amount of the present composition 1 by sight 25 from outside, such as glass and the others.

28 [0035] Also it is desirous that the chemical bottle 4 is constituted such that the present composition 1 that is charged into the bottle is neither leaked out nor oozed out 5 even at falling in terms of safety in use. [0036] In the Figure 1, an external cylinder can be arranged so as to cover the whole surroundings of the chemical bottle 4, and in this case, the bottom plate makes discoid 10 shape to facilitate a transfer of the chemical bottle 4 into or from the apparatus, or makes a possible constitution, for example, for hinge connection or fitting connection and the others to facilitate a desorption of the bottle together with the external cylinder. 15 [0037] It is desirous that such external cylinder makes a clear container or is set a notch on it partially so as to confirm the residual amount of the present composition 1 by sight from outside. 20 [0038] Also a pilot lamp for showing whether the electrical power is on or off may be set partially in the apparatus of the present invention. [0039] 25 [A method for controlling pests for heat transpiration] 29 The method for controlling pests for heat transpiration of the present invention uses the pesticidal material for heat transpiration of the present invention, wherein the method is characterized by dipping one end part 5 of the liquid-absorbing wick into the present composition to absorb the composition into the wick, and also by heating the surrounding of other end part of the wick to vaporize the absorbed composition. [0040] 10 In the Figure 1, the part of the wick 3, which part has been dipped into the chemical bottle 4, absorbs the present composition. The other end part of this liquid absorbing wick 3 is projected from the chemical bottle 4, and is heated by a ring-shaped heater 2. The heated 15 present composition vaporizes into atmosphere. [0041] In the present invention, the heater for heating the surrounding surface of the end part of the liquid-absorbing wick may be either a direct-heating heat generator or an 20 indirect-heating heat generator, and is preferably an indirect-heating heat generator, and the heating temperature is usually from about 40 0 C to about 150*C, and is preferably from about 85 0 C to about 145 0 C. A representative example of the indirect-heating heat 25 generator includes a ring-shaped electrical heater that 30 induces heating by energization.
