Description

Technical Field

[0001] This invention relates to the field of insect biology and behavioral research technology, and in particular to a multi-channel wavelength-division insect phototaxis screening experimental device. Background Technology

[0002] Insect phototaxis is an important area of ​​research in insect biology and behavior, and also the theoretical basis for green pest control in agriculture. Numerous studies have shown that different insect species, and even different sexes and developmental stages of the same species, exhibit significant differences in the range of light wavelengths their compound eyes are sensitive to. By precisely screening for the characteristic wavelengths that have the strongest attraction effect on target pests, and developing specialized insect-attracting light sources accordingly, it is possible to achieve efficient pest attraction and monitoring while minimizing interference with non-target insects (especially natural enemies and pollinators), thus achieving the precise control objective of "attracting pests and repelling beneficial insects." Therefore, establishing a scientific and efficient method for screening insect phototaxis wavelengths is of great practical significance for advancing the upgrading of physical and chemical pest control technologies in agriculture.

[0003] Currently, screening devices for insect phototaxis wavelengths typically only use a single wavelength of insect-attracting light source, allowing for the testing of the attraction effect of only one light wave on insects under the same experimental conditions. When comparing and screening multiple candidate wavelengths, researchers can only conduct tests in batches and in rotation, that is, changing different wavelengths of insect-attracting lamps successively in the same experimental device, or setting different wavelengths in multiple independent experimental devices, but conducting experiments at different times and in different spaces. This testing mode suffers from the inability to eliminate interference from individual and environmental variables, resulting in insufficient reliability of the comparison results, long experimental cycles, and low efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a multi-channel wavelength-division insect phototaxis screening device to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A multi-channel wavelength-division insect phototaxis screening device includes a movable box, an installation mechanism, and a trapping mechanism. The movable box includes a box body and a box cover. The box body is hollow inside with an opening on the top surface and multiple through holes spaced apart on its side walls.

The connecting component is detachably connected to the mounting cylinder. The trapping component includes an insect-attracting lamp and a high-voltage grid. The insect-attracting lamp and the high-voltage grid are connected to the connecting component, and the insect-attracting lamps in the multiple trapping mechanisms have different wavelengths. The collecting component is detachably connected to the connecting component.

[0006] Furthermore, the connecting assembly includes a connecting plate, a connecting frame, and a ring plate; the connecting plate is horizontally disposed on the top surface of the mounting cylinder, and its diameter is larger than that of the mounting cylinder; the connecting frame is vertically disposed inside the mounting cylinder, its interior is vertically through, its top surface is connected to the connecting plate, and its side wall has a hollow structure; the ring plate is horizontally disposed on the bottom surface of the connecting frame, and its interior is vertically through.

[0007] Furthermore, the insect-attracting lamp is located in the middle of the bottom surface of the connecting plate; the high-voltage grid is located on the bottom surface of the connecting plate and surrounds the insect-attracting lamp.

[0008] Furthermore, the connecting component also includes a locking block; the locking block is located on the bottom surface of the inner wall of the ring plate, and two are arranged circumferentially; the collecting component includes a collecting bottle; the collecting bottle is vertically arranged, and its bottle mouth is provided with a locking groove; the locking groove has an L-shaped structure, and two are provided corresponding to the locking block.

[0009] Furthermore, the top surface of the box lid has a vertically penetrating hole; the movable box also includes a hole cover; the hole cover is located on the hole of the box lid; it also includes a release mechanism; the release mechanism is used to put insects into the movable box.

[0010] Furthermore, the inner sidewall and bottom surface of the box, the bottom surface of the box cover, and the bottom surface of the hole cover are all provided with light-absorbing layers.

[0011] Furthermore, the release mechanism includes an insect collection box and a lid; the insect collection box has an insect collection opening on its side; the insect collection opening is provided with a plug; the lid is located on the top surface of the insect collection box, and multiple mesh holes are provided in the center of its top surface.

[0012] Furthermore, the release mechanism includes an insect-collecting net bag; the opening of the insect-collecting net bag can extend into the cover hole of the box lid.

[0013] Furthermore, the method of using this device includes the following steps: S1: Connect the attraction mechanism equipped with insect-attracting lamps of different wavelengths to the mounting tube; S2: Place the insect collection box containing a certain number of insects from a bright environment to a dark environment and let it stand still so that the insects can adapt to the dark environment; S3: In a dark room at night, turn on the insect-attracting lights and high-voltage grids of each trapping mechanism, remove the box lid, place the insect collection box in the box, open the box lid to release the insects from the collection box, and then quickly close the box lid to prevent the insects from escaping. S4: After a period of time, remove the collection bottle, collect the insects trapped by the insect-attracting lamps of different wavelengths, and calculate the trapping rate of the insects by the insect-attracting lamps of different wavelengths.

[0014] Furthermore, the method of using this device includes the following steps: S1: Connect the attraction mechanism equipped with insect-attracting lamps of different wavelengths to the mounting tube; S2: Place the insect-collecting net bag containing a certain number of insects from a bright environment to a dark environment and let it stand still so that the insects can adapt to the dark environment; S3: In a dark room at night, turn on the insect-attracting lights and high-voltage grids of each trapping mechanism, remove the hole cover, insert the opening of the insect-collecting net bag into the hole of the box cover, shake the insect-collecting net bag to shake the insects into the box, release the insects from the insect-collecting net bag, and then quickly close the hole cover to prevent the insects from escaping. S4: After a period of time, remove the collection bottle, collect the insects trapped by the insect-attracting lamps of different wavelengths, and calculate the trapping rate of the insects by the insect-attracting lamps of different wavelengths.

[0015] The advantages of this invention compared to the prior art are as follows: 1. This invention constructs a multi-channel wavelength-separated synchronous testing structure by opening multiple through holes at intervals around the side wall of the box and connecting them to the trapping mechanisms of insect-attracting lamps with different wavelengths. This structure enables parallel comparison of the trapping effects of multiple wavelengths in the same closed environment, with the same batch of insects, and at the same time period, significantly improving the accuracy and comparability of wavelength screening results.

[0016] 2. This invention integrates the insect-attracting lamp, the surrounding high-voltage grid, and the bottom collection bottle into the same attraction mechanism. Insects are automatically killed and fall directly into the collection bottle as they move towards the light, thus achieving integrated attraction, killing, and collection. After the experiment, the collection bottle can be directly removed for counting and statistics. The operation is simple, convenient, and practical.

[0017] 3. By setting light-absorbing layers on the inner side wall, bottom surface, bottom surface of the box lid, and bottom surface of the hole cover, this invention can effectively absorb stray and reflected light emitted by each attraction mechanism, thereby ensuring the accuracy of insect phototaxis testing.

[0018] 4. This invention designs the trapping mechanism as a modular structure that can be detachably connected to the mounting cylinder, and integrates the insect-attracting lamp, high-voltage grid and collection bottle into one unit. It can flexibly replace the trapping modules of different wavelengths according to the experimental requirements, which is convenient for switching between multi-wavelength rapid screening and optimal wavelength retesting. This greatly shortens the experimental cycle and improves the efficiency and versatility of the device. At the same time, the round tube can be removed from the box for easy storage.

[0019] 5. This invention, by setting up two release mechanisms—an insect-collecting box and an insect-collecting net bag—can adapt to the release needs of insects of different sizes and activity characteristics; combined with the quick-opening and closing design of the box lid and the hole cover, the box can be quickly sealed after the insects are released, effectively reducing the escape rate and damage rate of the insects during the release process.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and preferred embodiments. However, it should be noted that many details listed in the specification are merely to provide the reader with a thorough understanding of one or more aspects of the invention, and these aspects of the invention can be achieved even without these specific details.

[0022] Example 1 like Figure 1-7 As shown, a multi-channel wavelength-division insect phototaxis screening test device includes a movable box 1, a mounting mechanism 2, and a trapping mechanism 3. The movable box 1 includes a box body 11 and a box cover 12. The box body 11 has a polygonal structure; in this embodiment, the box body 11 is a regular hexagonal structure with a hollow interior, an open top surface, and six through holes 111 spaced apart on its side walls. The box cover 12 is located on the top surface of the box body 11. The mounting mechanism 2 includes a circular tube 21 and a mounting cylinder 22. The circular tube 21 is horizontally arranged, with one end connected to the through hole 111 of the box body 11 and the other end connected to the mounting cylinder 22. The mounting cylinder 22 is vertically arranged, with its interior vertically through, and a mounting hole 221 is provided on its side wall, through which it communicates with the round tube 21; the trapping mechanism 3 is provided in multiple parts, including a connecting component 31, a trapping component 32, and a collecting component 33; the connecting component 31 is detachably connected to the mounting cylinder 22; the trapping component 32 includes an insect-attracting lamp 321 and a high-voltage grid 322; the insect-attracting lamp 321 and the high-voltage grid 322 are connected to the connecting component 31, and the insect-attracting lamps 321 in the multiple trapping mechanisms 3 have different wavelengths; the collecting component 33 is detachably connected to the connecting component 31. Insects are placed in the box 11 of the activity box 1. After the trapping component 32 is activated, light enters the box 11 of the activity box 1 through the circular tube 21. Since insects are phototactic and have different sensitivities to different wavelengths, after the insect-attracting lamps 321 of different wavelengths are turned on, the insects will move through the circular tube 21 toward the insect-attracting lamp 321 of their most sensitive wavelength. During the process of moving toward the insect-attracting lamp 321, they are killed by the high-voltage grid 322 and enter the collection component 33. After the experiment, the trapping rate of the insect-attracting lamps 321 of each wavelength is counted based on the insects collected by the collection component 33.

[0023] The mounting mechanism 2 also includes a mounting plate 23; the mounting plate 23 has a through circular hole in the middle, and the outer wall of the circular tube 21 facing the box 11 is fixed in the circular hole of the mounting plate 23. The mounting plate 23 has through holes at its four corners, and the side wall of the box 11 has corresponding openings. The circular tube 21 and the box 11 are connected by bolts passing through the through holes of the mounting plate 23 and the openings of the box 11. When not in use, the circular tube 21 can be removed to reduce the space occupied and facilitate storage.

[0024] The connecting component 31 includes a connecting plate 311, a connecting frame 312, and a ring plate 313. The connecting plate 311 is horizontally positioned on the top surface of the mounting cylinder 22, and its diameter is larger than that of the mounting cylinder 22. The connecting frame 312 has a diameter slightly smaller than the inner diameter of the mounting cylinder 22 and is vertically positioned inside the mounting cylinder 22, with its interior vertically connected. Its top surface is connected to the connecting plate 311, and its side wall has a hollow structure. The ring plate 313 is horizontally positioned on the bottom surface of the connecting frame 312, and its interior is vertically connected. The diameter of the connecting plate 311 is larger than that of the mounting cylinder 22, so the connecting plate 311 can be directly placed on the top surface of the mounting cylinder 22, allowing the entire attracting mechanism 3 to be quickly connected to the mounting mechanism 2, facilitating disassembly and replacement. Insects move from the round tube 21 to the insect-attracting lamp 321, pass through the mounting hole 221 into the mounting cylinder 22, and enter the killing component 32 through the hollow side wall of the connecting frame 312. After contacting the high-voltage electric grid 322, they are killed and then fall downwards into the collection component 33.

[0025] The connecting plate 311 contains a main control board, a ballast, and a boost module, which are used to control the high-voltage power grid 322 and the insect-attracting lamp 321.

[0026] The insect-attracting lamp 321 is located in the center of the bottom surface of the connecting plate 311; the high-voltage grid 322 is located on the bottom surface of the connecting plate 311 and surrounds the insect-attracting lamp 321. The insect-attracting lamp 321 is located at the center of the high-voltage grid 322, which surrounds the insect-attracting lamp 321. When insects move towards the insect-attracting lamp 321, they will first come into contact with the high-voltage grid 322 and be killed.

[0027] The connecting component 31 further includes a locking block 314; the locking block 314 is located on the bottom surface of the inner wall of the ring plate 313, and two are spaced apart circumferentially; the collecting component 33 includes a collecting bottle 331; the collecting bottle 331 is vertically arranged, and its mouth is provided with a locking groove 332; the locking groove 332 has an L-shaped structure, and two are provided corresponding to the locking block 314. The collecting bottle 331 is connected to the ring plate 313 through the locking groove 332 and the locking block 314, which facilitates disassembly and assembly. After the experiment, the collecting bottle 331 is removed, the number of insects in the collecting bottle 331 is counted, and the trapping rate is calculated.

[0028] The top surface of the box cover 12 has a vertical through hole 121; the movable box 1 also includes a hole cover 13; the hole cover 13 is disposed on the hole 121 of the box cover 12; it also includes a release mechanism; the release mechanism is used to put insects into the movable box 1.

[0029] The top surface of the box cover 12 is also provided with a handle. There are two handles, which are respectively located on both sides of the cover hole 121.

[0030] The inner sidewalls and bottom surface of the enclosure 11, the bottom surface of the enclosure lid 12, and the bottom surface of the hole cover 13 are all provided with light-absorbing layers 14. The light-absorbing layer 14 is made of black flocked cloth and is used to prevent reflections from causing interference.

[0031] The release mechanism 4 includes an insect-collecting box 41 and a lid 42. The insect-collecting box 41 has an insect-collecting opening 411 on its side for placing insects inside, preventing escape when the lid 42 is opened directly. A plug 43, made of cotton, is provided on the insect-collecting opening 411 to prevent insects from escaping after being placed inside. The lid 42 is located on the top surface of the insect-collecting box 41, and has multiple mesh holes 421 in the center of its top surface to provide air to the insects. When releasing insects, the release mechanism 4 is placed in the housing 11 of the movable box 1, and the lid 12 is quickly closed after the lid 42 is opened to prevent insect escape. The release mechanism 4 in this embodiment can prevent insects from being injured during release and also prevents them from being startled during the release process.

[0032] Example 2 like Figure 1-6 As shown in Figure 8, the method of using a multi-channel wavelength-division insect phototaxis screening test device includes the following steps: S1: Connect the attracting mechanism 3, which is equipped with insect-attracting lamps 321 of different wavelengths, to the mounting tube 22; S2: Place the lid 42 of the release mechanism 4 on the insect collection box 41, remove the cotton on the insect collection opening 411, put a certain number of insects into the insect collection box 41 from the insect collection opening 411, then put the plug 43 back in, and place the insect collection box 41 from the light environment to the dark environment and let it stand for 1 hour to allow the insects to adapt to the dark environment. S3: To adapt to the diurnal activity rhythm of insects as much as possible, the experiment was conducted at 20:00 at night. In the dark room at night, the insect-attracting lamps 321 and high-voltage grids 322 of each trapping mechanism 3 were turned on. The box cover 12 was removed, and the insect collection box 41 was placed in the box body 11. The box cover 42 was opened to release the insects from the insect collection box 41. Then the box cover 12 was quickly closed to prevent the insects from escaping. S4: After 12 hours, remove the collection bottle 331, collect the insects trapped by the insect-attracting lamps 321 of different wavelengths, and calculate the trapping rate of the insects by the insect-attracting lamps 321 of different wavelengths.

[0033] Example 3 The method is basically the same as in Embodiment 1, except that the release mechanism 4 includes an insect-collecting net bag 44. The opening of the insect-collecting net bag 44 can extend into the cover hole 121 of the box cover 12. The insect-collecting net bag 44 has a drawstring bag structure. During release, the opening of the insect-collecting net bag 44 is inserted into the cover hole 121 of the box cover 12, and then the insect-collecting net bag 44 is shaken to shake the insects into the box body 11. Afterwards, the cover 13 is quickly closed to prevent the insects from escaping. The release mechanism 4 in this embodiment is more convenient to use, and the probability of insects escaping is lower.

[0034] Example 4 A method for using a multi-channel wavelength-division insect phototaxis screening device includes the following steps: S1: Connect the attracting mechanism 3, which is equipped with insect-attracting lamps 321 of different wavelengths, to the mounting tube 22; S2: Open the opening of the insect collection net bag 44, put a certain number of insects into the insect collection net bag 44, and then place the insect collection net bag 44 from the light environment to the dark environment and let it stand for 1 hour to allow the insects to adapt to the dark environment. S3: To adapt to the diurnal activity rhythm of insects as much as possible, the experiment was conducted at 20:00 at night. In the dark room at night, the insect-attracting lamps 321 and high-voltage grids 322 of each trapping mechanism 3 were turned on. The hole cover 13 was removed, and the opening of the insect-collecting net bag 44 was inserted into the cover hole 121 of the box cover 12. Then the insect-collecting net bag 44 was shaken to shake the insects into the box 11, so that the insects were released from the insect-collecting net bag 44. Then the hole cover 13 was quickly closed to prevent the insects from escaping. S4: After 12 hours, remove the collection bottle 331, collect the insects trapped by the insect-attracting lamps 321 of different wavelengths, and calculate the trapping rate of the insects by the insect-attracting lamps 321 of different wavelengths.

[0035] Example 5 When there are too many insect-attracting lamps 321 to be tested, multiple test devices can be set up. The trapping rate of each wavelength of insect-attracting lamp 321 can be tested according to the method of Example 2 or 4. The insect-attracting lamp 321 with better effect can be screened out. Then, the screened insect-attracting lamp 321 can be put into the same test device, and the optimal wavelength can be tested again according to the method of Example 2 or 4.

[0036] Phototaxis screening experiment of corn borer by different wavelengths of insect-attracting lamp 321 S1: Connect the attracting mechanism 3, which is equipped with insect-attracting lamps 321 of different wavelengths, to the mounting tube 22. The wavelengths of each insect-attracting lamp 321 are 365 nm, 445 nm, 525 nm, 605 nm, 685 nm, and 765 nm, respectively. S2: Place the lid 42 of the release mechanism 4 on the insect collection box 41, remove the plug 43 on the insect collection opening 411, put 60 corn borers (female to male) into the insect collection box 41 through the insect collection opening 411, then put the plug 43 back in, and place the insect collection box 41 from the light environment to the dark environment for 1 hour to allow the corn borers to adapt to the dark environment. S3: To adapt to the diurnal activity rhythm of the corn borer as much as possible, the experiment was conducted at 20:00 at night. In the dark room at night, the insect-attracting lamps 321 and the high-voltage grid 322 of each trapping mechanism 3 were turned on, and the lights in the dark room were turned off. The box cover 12 was removed, and the insect collection box 41 was placed in the box body 11. The box cover 42 was opened to release the corn borer from the insect collection box 41. Then the box cover 12 was quickly closed to prevent the corn borer from escaping. S4: After 12 hours, remove collection bottle 331, collect corn borers trapped by insect-attracting lamps 321 of different wavelengths, and calculate the trapping rate of insects by insect-attracting lamps 321 of different wavelengths.

[0037] Female insect trapping rate = (Number of female insects trapped / Number of female insects released) × 100%; Male insect trapping rate = (Number of male insects trapped / Number of male insects released) × 100%; Overall trapping rate = (Total number of corn borers trapped / Total number of corn borers released) × 100% The total number of corn borers trapped = the number of females trapped + the number of males trapped + the number of corn borers whose sex could not be determined. The experiment was repeated three times, and the data were transformed by arcsine square root and differential analysis was performed using Duncan's new complex range method.

[0038] The results are shown in Table 1.

[0039] Table 1. Trapping effect of insect-attracting lamps of different wavelengths on corn borers. The values ​​in the table are the average trapping rates. The uppercase and lowercase letters following the values ​​indicate that the differences are significant at the 0.01 and 0.05 levels, respectively.

[0040] As shown in Table 1, the 365 nm wavelength insect-attracting lamp significantly increased the trapping rates of female and male corn borers, as well as the total trapping rate, compared to other wavelengths. These results indicate that among the experimental wavelengths, 365 nm exhibited the best trapping effect on corn borers and can be considered the preferred light source wavelength for insect-attracting lamps targeting this pest.

[0041] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
