Embodiments of the present invention will be described below with reference to the drawings.

1 to 4 shows an attracting insecticidal device according to the present invention. The attracting insecticidal device A has a sound generating means 1 for generating a synthetic sound for attracting a mosquito K and the same sound generating means. Insecticidal means 2 for killing mosquitoes attracted by means 1 by high voltage
And a protection means 3 for protecting humans from the insect killing means 2.

As shown in FIG. 4, the sound generating means 1 comprises a speaker 4, a power amplifier 5, a modulation circuit 6, a tone burst circuit 7, a power supply circuit 8, an external power supply 9 or a solar cell 10 connected in series. Is forming.

As shown in FIGS. 1 to 3, the speaker 4 is arranged between a cylindrical circuit case 11 and a circular tray 12 which are vertically opposed to each other with a speaker strut 13 interposed therebetween. In the circuit case 11, the power amplifier 5, the modulation circuit 6, the tone burst circuit 7, the power supply circuit 8 and a high voltage generation circuit 16 described later are arranged. 14 is a support for the circuit case.

Further, the speaker 4 is a three-dimensional concentric circular emission type that emits sound in four directions in front, back, left and right in order to have an attracting effect on the surrounding mosquito K, and the output sound pressure is the average sound of the outdoors. With reference to the pressure of 40 dB, use one that can secure at least 64 dB with a sound source of 1 m.

As an electronic memory IC memory, a voice kit for each mosquito species is externally attached according to the application.

As shown in FIG. 4, the insect killing means 2 is composed of an electrode 15 connected to the power supply circuit 8 and a high voltage generation circuit 16 connected to the electrode 15.

As shown in FIGS. 1 to 3, the electrode 15 has a positive electrode rod 15a and a negative electrode rod 15a on the same circumference centered on the speaker column 13 between the circuit case 11 and the tray 12. 15b and 15b are erected at a fixed interval t1.

Here, the interval t1 between the positive and negative electrode rods 15a and 15b
As shown in FIG. 3, the mosquito K has a slightly narrower width than the widened width t2 of the mosquito K, and the left and right wings of the mosquito K have positive and negative electrode rods.
By making contact with 15a and 15b respectively, electricity is supplied to cause shock death or the blades are removed so that they can be dropped into the tray 12.

Further, the electrode 15 is connected to the electrode 15 through the power supply circuit 8.
By applying an AC voltage of 0 V, the high voltage generation circuit 16 can reduce the secondary boosted voltage to a voltage at which mosquito K is shocked and dropped, for example, 500 V. As an arrangement, for example, a pulse of 0.02 seconds can be continuously driven by an AC power supply of 5 mA and 500 V every 1 second.

As shown in FIGS. 1 and 2, the protection means 3 has a protective net 20 attached so as to surround the outer peripheral portion between the circuit case 11 and the tray 12, and the protective net 20 allows Humans and animals are prevented from directly touching the electrodes 15 to which a high voltage is applied, and humans and animals can be protected when a short circuit occurs between the electrodes due to water droplets.

As shown in FIG. 3, a heating element 26 such as a seat heater or a nichrome wire is attached near the speaker 4, and the heating element 26 is used to control the temperature near the speaker 4, for example. The temperature is kept at 40 ° C, for example.

This is because the female mosquito has a behavior of reacting to the body temperature difference between the external environment and the animal, so that the heating element 26 enhances the attracting effect of the mosquito.

Here, in general, when a mosquito K mates,
A so-called running noise, in which male mosquitoes are attracted to the feather noise (flying sound) of female mosquitoes, is recognized, and there is a characteristic that males and females encounter depending on the nature. Further, in the blood-sucking mosquito K, many types of female mosquitoes have a property that black non-reflective objects are used as a collective marker, and the female mosquitoes fly around in groups and gather on the heating element 26 at a specific temperature.

When male mosquitoes are attracted to the female mosquito's wing noise, different wing noise depending on the type of mosquito K serves as a stimulation for female search. For example, Aedes albopictus, Culex pipiens, Culex tritaeniorhynchus, etc., which are known to harm humans and animals,
The wings of males and females differ depending on the species, and they are only attracted to the wings of females of the same species.

Therefore, by selecting individually,
It is possible to attract and kill the desired mosquito females.

When the attracting and insecticidal device A according to the present embodiment is effectively used, scientifically published data on the ecology of the domestic blood-sucking mosquitoes Aedes albopictus, Culex pipiens, Culex pipiens, and the wing noise frequency of female mosquitoes can be summarized as follows. It is as shown in Table 1 below.

[0034]

[Table 1]

Acoustically analyze the feather noises of various female mosquitoes flying outdoors, and with reference to the published academic data,
The parameters of the synthetic signal sound reflecting the acoustic characteristics of the female mosquito wings of each species were obtained.

To create a synthetic signal for attracting the mosquito K, the kind of waveform which is an acoustic characteristic, frequency,
The harmonic composition, the amplitude level, and the time axis arrangement are examined, and the amplitude modulation is applied to the rising of the fundamental frequency of the sinusoidal waveform, and both the frequency and the amplitude are modulated to the rising, so that the female mosquito approaches from a distance and becomes male. A synthetic sound that reflects the dynamics of the flight sound of a mosquito due to the Doppler effect that approaches and gradually leaves.

Next, the acoustic characteristics of the effective synthetic sound Q of the female mosquito sound will be described with reference to FIGS. 5 and 6.

As shown in FIG. 5, the waveform type is sine wave.

As shown in FIG. 5, the radiation sound pressure P is set to a constant radiation sound pressure P1 at a sound source distance of 1 m, for example, 64 dB.

As shown in FIG. 5, the synthetic sound Q is repeated for a fixed time T7, for example, on for 6 seconds and off for 6 seconds, and then for a fixed time T1, for example, 20 minutes, as shown in FIG. Then, a cycle of resting for a fixed time T2, for example, 5 minutes is continued for a fixed time T3, for example, 3 hours a day.

The synthesized sound Q generated during the fixed time T7 is frequency-modulated between 600 and 650 Hz.

As shown in FIG. 5, during ON for 6 seconds, amplitude modulation from zero amplitude to peak (constant radiant sound pressure P1) is performed for the first constant time T4, for example, 1.5 seconds, and then the next constant time T5. For example, the flatness (constant radiant sound pressure P1) is maintained for 3 seconds, and the amplitude is modulated from the peak (constant radiant sound pressure P1) to zero amplitude for the final constant time T6, eg, 1.5 seconds.

When the inverse square law of the distance is simply applied to the range of the effective reach distance from the sound source of the synthetic sound Q obtained as described above, the sound pressure of 1 m of the sound source is 64 dB, and the sound pressure of 2 m in the vegetation and the ground surface is 2. If there is no subsequent attenuation, it will be attenuated to 40 dB at a sound source distance of 16 m, and this 40 dB is the sound pressure at 0.5 cm of the flight sound of a mosquito. Therefore, the range in which the synthesized sound Q of 40 dB by the four-way speaker reaches is 1,024 m ² (310.3 tsubo).

In this embodiment, the device for attracting and killing the mosquito K has been described. However, by appropriately changing the frequency modulation or amplitude modulation of the synthetic sound Q for attracting by the sound generation means 1, other devices can be used. Similarly, the harmful insects can be attracted and killed.

[0045]

According to the present invention, the following effects can be obtained.

That is, according to the attracted insecticidal device of the present invention, only the harmful insects that cause great damage to the comfortable life of humans and animals can be electrically eradicated without using chemicals.

Therefore, it is possible to solve all the problems that have been problems when using conventional drugs, such as problems to the human body and water pollution, and development of resistant varieties due to a decrease in sensitivity level due to drugs. At the same time, the eradication of beneficial insects can be prevented.
