2. Description of the Related Art Conventionally, pest control in factories such as food factories, pharmaceutical factories, and bag-making factories involves a wide variety of pests and a wide variety of infestation routes. It is carried out by a specialized trader or the like.

[0003] The method of controlling flying pests by a specialist is generally a method of spraying a chemical such as an insecticide into a space using a sprayer or a fogger, or a method of electrocuting a flying pest using an attracting electric insecticide. The mainstream is a treatment method that requires relatively large human work, such as a method of collecting or repelling flying pests using an attracting trap or an insect repellent film.

However, the method of controlling flying pests by a specialized trader has the drawback that not only the work such as production in a factory must be interrupted during the control work, but also that it requires a huge cost. .

Therefore, in recent years, in order to improve the efficiency of human work,
An automatic processing method using an ultrasonic spray device, a heat evaporation device, a gyro smoke, or the like has been proposed.

However, these automatic processing methods are not satisfactory control methods because they require maintenance such as parts replacement and safety devices.

An aerosol can be produced by a conventional method by filling an aerosol container with a stock solution containing a pyrethroid-based insecticide and a solvent suitable for controlling flying pests, and a propellant.

Next, an automatic aerosol spraying device used in the present invention will be described with reference to the drawings, but the present invention is not limited to only such an embodiment.

FIG. 1 is a schematic explanatory view showing one embodiment of an aerosol automatic spraying device used in the present invention.

As shown in FIG. 1, the aerosol automatic spraying device mainly comprises an aerosol 1 and an automatic spraying device main body 2.

The main body 2 of the automatic spraying device is provided with a motor 3 and a driving force converter 4 for converting the driving force of the motor 3 into a vertical movement and interlocking the vertical movement with the push button 5 of the aerosol 1. I have.

The driving force conversion device 4 converts the rotational motion of the motor 3 into a vertical motion. In the driving force conversion device 4 shown in FIG. 1, the rotational motion of the motor 3 is interlocked with the cam 8 via the gear 7,
Since the cam 8 moves in an arc around the support shaft 9, the operating portion 6 moves up and down. Since the push button 5 is pressed or released by the vertical movement of the operating section 6, the nozzle (not shown) of the aerosol 1 is opened and closed. Thereby, the aerosol 1 is discharged from the spray port 10 of the push button 5.
(Not shown) is released into the atmosphere.

Note that an aerosol support plate 11 and a receiving stand 12 may be provided in the automatic spraying device main body 2 to hold the aerosol 1.

Further, a control unit 13 for controlling a spray interval is provided in the main body 2 of the automatic spraying apparatus.

A substrate 14 is provided in the control unit 13, and the spray interval is controlled by the substrate 14. Further, in order to adjust the spray timing of the content sprayed from the aerosol 1 on the substrate 14,
A timer (not shown) may be provided.

The substrate 14 is provided with a spray interval setting device 15 for adjusting the spray interval of the content sprayed from the aerosol 1 and a power switch 16.

In the main body 2 of the automatic spraying device shown in FIG. 1, a battery (not shown) is provided as a starting force source. As such a battery, for example,
A dry battery, a rechargeable secondary battery, or the like can be used. As described above, in the present invention, when a battery is used, wiring from an electric light line or the like is unnecessary, and the aerosol automatic spraying device can be easily installed at a desired location, so that safety is improved. , Operability,
There is an advantage of being excellent in portability and the like.

The driving force converter 4 and the controller 13 are electrically connected together with a battery.

Thus, the automatic aerosol spraying device is constituted, and the automatic aerosol spraying device used in the present invention has a function capable of setting and controlling the spray amount per one spray and the spray interval to desired values. And the structure is arbitrary.

When the contents are sprayed from the nozzle of the aerosol push button of the aerosol automatic spraying device, spray particles of the stock solution are formed. The average particle size of the spray particles at the time of spraying [50% particle size in the volume integrated distribution in space] is 8 to 2
It is desirably 5 μm, preferably 8 to 15 μm. When the average particle size of the spray particles exceeds the upper limit, the diffusibility of the spray particles deteriorates and the insecticidal effect varies, and when the average particle size is smaller than the lower limit, the spray particles Although there is no problem in the diffusivity of the spray particles, the distribution of the spray particles is disturbed by the leakage of the spray particles from a gap in the room or the flow of wind when a person enters or exits, and the insecticidal effect is reduced.

The spray amount per spray of the contents sprayed from the aerosol of the automatic aerosol spray device is 0.0
Is adjusted within a range of 03~0.06mL / m ^3. If the spray amount is smaller than the lower limit, it becomes difficult to uniformly diffuse the spray particles in the space. If the spray amount is larger than the upper limit, contamination may occur.

The amount of the pyrethroid-based insecticide sprayed per day cannot be determined unequivocally because it varies depending on the type and space volume of the pyrethroid-based insecticide. It is preferably about 0 mg / m ³ . When the spray amount per day of the pyrethroid-based insecticide is less than the lower limit, the insecticidal effect becomes uneven, and when the spray amount is more than the upper limit, the safety to the human body is reduced. Or cause contamination due to adhesion to the human body.

The spray interval when the contents are sprayed from the aerosol of the aerosol automatic spraying device is adjusted within a range of 15 to 90 minutes. If the spraying interval is shorter than the lower limit, there is a possibility that contamination by the ejected contents or accumulation of the contents may be caused, and if the spraying interval is longer than the upper limit, the ejected contents may be reduced. Due to the small number of suspended particles, the insecticidal effect is reduced.

Next, the mode of use of the aerosol automatic spraying device will be described. FIG. 2 is a schematic explanatory view showing one embodiment of a use state of the aerosol automatic spraying device.

In FIG. 2, reference numeral 17 denotes a factory. Factory 1
An aerosol automatic spraying device 19 is attached to the side wall of the front chamber 18 of the seventh embodiment. The attachment position of the aerosol automatic spraying device 19 is not particularly limited and is arbitrary, and may be appropriately adjusted in consideration of the insecticidal effect, operability, and the like.

[0045]

Next, the present invention will be described in more detail with reference to examples, but the present invention is not limited to only these examples.

Example 1 Transfluthrin 3.5 as a pyrethroid insecticide
A stock solution consisting of 11.9 parts by weight of ethanol and 11.9 parts by weight of ethanol;
84.6 parts by weight of LPG was mixed as a propellant, and the contents for aerosol were filled in an aerosol container to obtain an aerosol.

Next, this aerosol was attached to the main body of the automatic spraying apparatus, and an automatic aerosol spraying apparatus was manufactured. Using this automatic aerosol spray device, the control effect of flying insect pests was examined under the following conditions.

A. Test insects Culex pipiens pallens Drosophila (Telmatoscopus albipunctatus) As test insects, room temperature (28 ° C), long day conditions (14L10D)
The population being raised in was used.

B. Test method (falling elevation effect) 8 tatami (3.60 m x 3.68 m, area: 13.2 m ² ,
An aerosol automatic spraying device was installed in a test room (height: 2.5 m) (fixed to the side wall at a height of 2 m from the floor).

First, the contents are sprayed from the aerosol automatic spraying device to the space in the test room at a predetermined spraying amount, and each test insect is sown at 10, 15, 30, 60, or 120 minutes after the end of spraying. Fig. 3 shows five net baskets containing about 10 animals.
And the drop elevation time (KT ₅₀ ) of the test insects was examined, and the spray interval and spray amount, which are the automatic spray conditions of the automatic spray device, were estimated. The results are shown in Tables 1 and 2.

[0051]

[Table 1]

[0052]

[Table 2]

From the results shown in Tables 1 and 2, if the elapsed time (continuation) showing the effect of falling and turning at each spray amount of the contents is within 90 minutes, the test insects fall and turn in a short time. However, for 120 minutes, even if the spray amount is large, the effect is not improved.

On the other hand, the spray amount to the space is 0.003 mL /
When it is less than m ³ , it is understood that uniform diffusion into the space is not sufficiently performed, and that it takes a long time to fall and turn. The same tendency was shown, although there was a difference in the time required to fall and elevate depending on the type of test insect.

From this, it is understood that it is appropriate that the interval of spraying the contents from the aerosol of the automatic spraying device is 15 to 90 minutes and the spraying amount is 0.003 to 0.06 mL / m ³ .

Example 2 An aerosol was obtained by mixing an undiluted solution composed of a pyrethroid insecticide and a solvent shown in Table 3 with a propellant and filling the contents for aerosol into an aerosol container.

Next, this aerosol was attached to the main body of the automatic spraying apparatus, and an automatic aerosol spraying apparatus was manufactured. Using this automatic aerosol spray device, the control effect of flying insect pests was examined under the following conditions. Table 3 shows the results. A. Test insects Housefly (Musca domestica) As test insects, an individual population bred under room temperature (28 ° C.) and long-day conditions (14L10D) was used. B. Test method (falling elevation effect) 8 tatami (3.60 m x 3.68 m, area: 13.2 m ² ,
An aerosol automatic spraying device was installed in a test room (height: 2.5 m) (fixed to the side wall at a height of 2 m from the floor).

The spray particles having the average particle diameter shown in Table 3 were sprayed from the aerosol of the aerosol automatic spraying device into the space in the test room. After 30 minutes and 60 minutes from the end of spraying, about 10 test insects were tested. The five net baskets are placed at the locations shown in Fig.
Examined T _50), we investigated the effect of the effect of the average particle size difference between the spray particles. The number of times a person entered and exited the test room during the test period was a total of four times.

[0059]

[Table 3]

From the results shown in Table 3, when the average particle diameter of the spray particles is 8 μm or less, [Test Nos. 1, 6,
11, 16, 21], it can be seen that the uniform diffusibility of the spray particles is deteriorated, and the drop elevation effect varies.

When the average particle diameter of the sprayed particles is 25 μm or more, [Test No. 5, 10, 15, 20, 2,
5] It can be seen that since the particle size is large, the floating properties are poor, and the control effect is poor.

From the above results, it is understood that it is appropriate that the average particle size of the spray sprayed from the aerosol of the automatic spraying device is in the range of 8 to 25 μm.

Example 3 A stock solution composed of a pyrethroid insecticide and a solvent shown in Table 4 was mixed with a propellant, and the contents for aerosol were filled in an aerosol container to obtain an aerosol.

A. Test insects Housefly (Musca domestica) As test insects, an individual population bred under room temperature (28 ° C.) and long-day conditions (14L10D) was used.

B. Test method (falling elevation effect) 8 tatami (3.60 m x 3.68 m, area: 13.2 m ² ,
An aerosol automatic spraying device was installed in a test room (height: 2.5 m) (fixed to the side wall at a height of 2 m from the floor).

Four types of contents having different ratios of the stock solution and the propellant shown in Table 4 were sprayed into the space in the test chamber by an aerosol automatic spraying device, and after 30 minutes from the start of spraying, about 10 test insects were put. Three cages made of nets were placed at the locations shown in Fig. 3, and the time required for the test insects to fall and elevate (KT ₅₀ ) was examined, and the effect of the difference in the ratio between the undiluted solution and the propellant on the contents was examined. .
The number of times a person entered and exited the test room during the test period was three times.

[0067]

[Table 4]

From the results shown in Table 4, it can be seen that when the ratio of the undiluted solution is high, the test insects are inferior to the fall and fall (Test No. 4). This is considered to be due to the fact that as the stock solution increases, the floating of the drug in the space becomes worse.

When the amount of the undiluted solution is small (test number 1), it is considered that the buoyancy of the spray particles in the space is improved. However, in practice, it cannot be uniformly diffused by the flow of air or the like, so that it is found that the test insect falls unevenly.

From the above, it can be seen that it is appropriate that the volume ratio between the stock solution and the propellant (stock solution / propellant) is from 10/90 to 40/60.

Example 4 (Field test) Transfluthrin 3.5 as a pyrethroid insecticide
A stock solution consisting of 11.9 parts by weight of ethanol and 11.9 parts by weight of ethanol;
84.6 parts by weight of LPG was mixed as a propellant, and the contents for aerosol were filled in an aerosol container to obtain an aerosol.

Next, this aerosol was attached to the main body of the automatic spraying apparatus, and an automatic aerosol spraying apparatus was manufactured. Using this automatic aerosol spray device, a test was performed under the following conditions.

A. Test method Place: Front room at entrance of textile factory (2.5m × 2.5m, area: 6.25m ² , height: 2.5m) Spray amount: 0.006ml / m ³ (per time) Operating conditions : 24 hours operation, spray interval 30 minutes

An automatic aerosol spraying device was installed (fixed to the side wall at a height of 2 m from the floor). Thereafter, an insect trap for flying insects was installed in the factory, and the number of insects entering the factory for 30 days before the treatment was counted.

Next, the contents were sprayed from the aerosol of the aerosol automatic spraying device into the space in the test room, and the number of insects entering the factory for 30 days was counted.

As a result, before the treatment, the number of insects (Chironomidae, Drosophila, moth, fly, leafhopper, bee, thrips, etc.) was 382, whereas after the treatment, the number was 68.
Was one. From this, it is understood that the invasion of flying insects can be prevented by periodically spraying the contents from the aerosol of the aerosol automatic spraying device into the space in the test room.

Example 5 (Field test) Transfluthrin 3.5 as a pyrethroid insecticide
A stock solution consisting of 11.9 parts by weight of ethanol and 11.9 parts by weight of ethanol;
84.6 parts by weight of LPG was mixed as a propellant, and the contents for aerosol were filled in an aerosol container to obtain an aerosol.

Next, this aerosol was attached to the main body of the automatic spraying apparatus, and an automatic aerosol spraying apparatus was manufactured. Using this automatic aerosol spray device, a test was performed under the following conditions.

A. Test method Location: Front room at entrance of chemical plant (4m × 3.5m, area:
14 m ² , height: 3 m) Spray volume: 0.006 ml / m ³ (per time) Operating conditions: 24 hours operation, spray interval 30 minutes

An automatic aerosol spraying device was installed (fixed to a side wall at a height of 2 m from the floor). An insect trap for flying insects was installed inside the factory, and the number of insects entering the factory for 30 days before treatment was counted.

Next, the contents were sprayed from the aerosol of the automatic aerosol spraying device into the space in the test room, and the number of insects entering the factory for 30 days was counted.

As a result, the number of insects before the treatment was 489, but the number of insects after the treatment was reduced to 85. In addition, creeping insects were also eliminated in the anterior chamber.

From this, it can be seen that by spraying the contents from the aerosol of the automatic aerosol spraying device into the space in the test room, it is possible to prevent the invasion of flying pests and to exterminate the creeping pests. .
