Description

Lighting device to prevent lychee moth pests

This work is about a lighting device for preventing lychee moth pests, especially a lighting device that can provide optimal spectral conditions for lychee moth control.

According to the lychee fine moth (Conopomorpha sinensis Bradley) is one of the main pests that damage lychee fruit. Adults are attracted by the aroma substances of young leaves, flowers and fruits, and cause harm to young leaves, flowers and fruits. When they harm fruits, they will cause severe fruit drop at the stalk of the fruit, reducing the yield, quality and economic benefits of lychees. If it is not properly controlled, the damage rate to the fruit can reach 100%.

At present, the main control method to reduce the lychee moth in orchards is to use pesticides. In order to reduce the amount of pesticides, some companies develop non-pesticide control methods, such as using the characteristics of insects to attract light or avoid light, and use specific wavelengths for pest management. Among them, Existing illumination studies on the lychee moth show that the lychee moth has a photophobic property, and the use of LED white light illumination can inhibit the activity of the lychee moth, reduce the number of eggs laid and the fruit damage rate, but the behavior of the lychee moth with different spectra is not known influence.

Therefore, in the absence of understanding of the sensitivity of lychee moth to different spectrums and the influence of night light on the quality of lychee fruit, it is still difficult to popularize the use of light for pest management in the lychee industry. However, with the increasing awareness of environmental protection and food safety. , Because the problem of pesticide residues caused by the application of pesticides to control insect pests has caused difficulties in the export and marketing of lychees, it is imperative to promote the physical control technology of light to control insect pests.

The reason is that the author of this article has taken advantage of the existing factors such as the inability to understand the sensitivity of the lychee moth to different spectra and the influence of night light on lychee fruits, resulting in the inability to popularize and implement the physical technology of light-based pest control. With the assistance of manufacturing and design experience and knowledge in related fields, and through ingenious thinking, this creation has been developed.

This creation is about a lighting device for preventing lychee moth pests, and its main purpose is to reduce the use of pesticides and provide a lighting device with optimal spectral conditions that can effectively prevent and control the lychee moth.

In order to achieve the above-mentioned implementation purpose, the author has developed the following lighting device for preventing lychee moth pests, which is mainly provided with a light-emitting unit, the light-emitting unit includes at least one lamp, and the wavelength emitted by the at least one lamp is within the range of 400nm~ Between 540nm, there is a control unit, and a drive circuit is arranged in the control unit to connect with the lamp by wired or wireless signal, and the lamp and the control unit are electrically connected with a power supply unit.

In the above-mentioned lighting device for preventing lychee moth pests, the control unit is further provided with a light intensity variable circuit to set the light intensity emitted by the lamps of the light-emitting unit.

In the above-mentioned lighting device for preventing lychee moth pests, the control unit is further provided with a flickering time and frequency modulation circuit to set the flickering frequency and time of the lamps of the light-emitting unit.

The above-mentioned lighting device for preventing lychee moth pests, wherein the flickering frequency modulation circuit of the control unit sets the flickering frequency of the lamp to be 0.3 to 120 Hz, and further sets the flickering time of the lamp to be 0.1 seconds to 5 minute.

In this way, the whole lychee litchi was illuminated by using the photophobic characteristics of the lychee moth. The results showed that 460nm, 520nm and mixed white light wavelengths can effectively reduce the activity, egg production and fruit damage rate of the lychee moth, and can be further used to control the The flickering frequency modulation circuit set in the unit controls the flickering time and frequency of the lamps of the light-emitting unit. The flickering frequency is 0.3 to 120 hertz (Hz). According to the control strategy of flickering light, not only can it frighten the lychee moth, and its activity, egg production and damage rate can be more effectively reduced, it can also achieve substantial benefits such as saving electricity costs. Use of pesticides, and improve the safety of lychees and other benefits.

In order to make the technical means of this creation and the effects that can be achieved, a more complete and clear disclosure, the detailed description is as follows, please refer to the disclosed drawings and drawing numbers together:

First of all, please refer to the first picture. The lighting device for preventing lychee moth pests is mainly composed of:

A light-emitting unit (1) comprises at least one lamp (11), the wavelength emitted by the at least one lamp (11) is between 400 nanometers (nm) and 540 nanometers (nm), and the lamp (11) ) can emit a single wavelength or a mixed wavelength, the mixed wavelength can be mixed white light, etc., the lamp (11) can be a light emitting diode [LED];

A control unit (2) is connected with the light-emitting unit (1) by wired or wireless signals, and the control unit (2) is provided with a driving circuit (21), a light intensity changing circuit (22) and a flicker frequency modulation circuit (23);

A power supply unit (3) is electrically connected with the light-emitting unit (1) and the control unit (2).

Accordingly, when carrying out the activity test of lychee moth, several observation boxes were placed in several observation boxes, and lamps with wavelengths between 400nm and 540nm were installed in the observation boxes (11) In addition, lamps (11) with other wavelengths are also installed for comparison, so that the lamps (11) of 400 nm, 460 nm, 520 nm, 600 nm, 660 nm, 740 nm, mixed white light and mixed yellow light are respectively installed in several observation boxes. , and the driving circuit (21) of the control unit (2) controls the opening and closing of the number of lamps (11), and the light intensity of the number of lamps (11) is set to 0.5 by the light intensity variable circuit (22). μmolm ^-2 s ^-1 , and another observation box was set to a dark environment as a control group. Therefore, the test results show that, please also refer to the second figure, the average moving distance of the lychee moth in a total dark environment for 30 minutes is about 480.1cm, and the short wavelength of 400nm ~ 600nm is longer than the long wavelength of 660nm ~ 740nm, It has a significant inhibitory effect on the motility of the lychee moth, and mixed white light and mixed yellow light can also reduce the motility of the lychee moth. In the immobile state, the average moving distances in 30 minutes are only 8.7cm, 3.8cm and 3.5cm. Therefore, it can be seen that the lychee moth is more sensitive to short wavelengths and can effectively reduce its activity.

The egg-laying test of the lychee moth was also carried out, and lamps (11) such as 400nm, 460nm, 520nm, 600nm, 660nm, 740nm, mixed white light and mixed yellow light were installed in several observation boxes respectively.

Here, the test results show that, please refer to the third figure, when the lychee moth is in the short wavelength environment of 400nm ~ 520nm, its egg production is significantly lower than that in the long wavelength light environment of 600nm ~ 740nm, and in the In the high light intensity environment of 0.5μmolm ^-2 s ^-1 , the number of eggs laid is less than 0.1μmolm ^-2 s ^-1 in the low light intensity environment, and under the light intensity setting of 0.5μmolm ^-2 s ^-1 , 460nm, 520nm and mixed The spawning quantity of the white light wavelength was significantly lower than that of other wavelength treatments, which could reduce the spawning quantity by 99.3%, 93.0% and 98.6%.

In addition, a field test of the damage rate of lychee moth to fruit pedicles at night under different wavelengths is carried out. Please refer to the fourth and fifth figures together. Several lamps (11) are set on the periphery of a lychee tree (4). , and at a position about 30 cm higher than the tree, when the lychee tree (4) bears fruit, the miscellaneous branches and leaves should be cut off, so that the light emitted by the lamp (11) can penetrate into the lychee tree (4). 11) is located in the middle of the lychee tree (4), and hangs down from the planting crown of the lychee tree (4) to the interior of the lychee tree (4), so as to illuminate the interior of the lychee tree (4), and set up the lamp (11) according to the way to reduce the blind spot of irradiation. According to this, lamps (11) that can emit wavelengths of 400nm, 460nm, 520nm, 600nm, 660nm, 740nm, mixed white light and mixed yellow light are set up on different lychee trees (4) for testing. Referring to Figure 6, in the 400nm, 600nm, 660nm and 740nm wavelength lighting environment, the damage rates of the lychee moth to the fruit pedicle were 36%, 32%, 32% and 38% respectively, and at 460nm, 520nm, In the mixed white light and mixed yellow light wavelength lighting environment, the damage rates of lychee moth to fruit stems were 10%, 6%, 16% and 18%, respectively. In addition, the damage rate of the control group in the dark environment at night was as high as 72%.
