Description

Technical Field

[0001] The present invention relates to the technical field of virulence determination tests, and specifically to a virulence determination test system and method for a Bemisia tabaci control agent. Background Art

[0002] Bemisia tabaci is a worldwide plant pest and an important research object in the field of plant protection. In China, the main control method for Bemisia tabaci is chemical control. During the development of control agents, it is often necessary to conduct activity determination and resistance monitoring of control agents against Bemisia tabaci, and the determination tests of virulence are involved in relevant scientific research processes in the field of control agent research. Different concentrations of control agents have significant differences on Bemisia tabaci. In order to compare the control effects of different concentrations of control agents on Bemisia tabaci, a large number of tests are required to determine the concentration of the control agent with the best control effect. However, for a long time, the existing virulence determination equipment mostly relies on manual operation during the determination process, with low work efficiency and long determination cycles. It is impossible to automatically conduct large-scale virulence determinations on different concentrations of control agents. Moreover, it is inconvenient to intermittently put the collected Bemisia tabaci into the test box for determination during the virulence test. There is a safety risk when putting them in manually. If too many are put in at one time, it is likely to lead to inaccurate test results and is not conducive to observing and analyzing the reactions and changes of Bemisia tabaci to different concentrations of the agent. At the same time, during the virulence determination test, the medicine is usually prepared manually. The original medicine is in the form of a powder, which needs to be dissolved with a solvent. However, there are problems such as insufficient stirring, time-consuming and laborious, complex operation, and many concentration gradients in the medicine preparation, which are prone to confusion. For this reason, we propose a virulence determination test system and method for a Bemisia tabaci control agent. Summary of the Invention

[0018] The method for a toxicity determination test system of a Bemisia tabaci control agent according to any one of the above includes the following steps:

[0019] S. Configure the concentration gradient: Select the to-be-tested technical drug, place the to-be-tested technical drug into the medicine preparation box from the feeding port, add an appropriate amount of water to dissolve it, start the dispensing module, fully stir the to-be-tested technical drug to prepare the agent, and then start the conveying and ratio module to configure the required agent concentration and convey it into each medicine bottle, so as to accurately evaluate the toxicity of the agent.

[0020] S. Prepare the test materials: Place healthy adult or nymph Bemisia tabaci into the intermittent insect supply module, ensure that the number of Bemisia tabaci is sufficient for the toxicity determination test, and control the opening and closing of the plurality of fan-shaped collection boxes through the collection driving module to place the test materials into the fan-shaped collection boxes.

[0021] S. Conduct the toxicity determination test: Start the intermittent insect supply module to supply insects into the fan-shaped test box, connect the adult or nymph Bemisia tabaci to the test materials, start the control valve, spray a set amount of agent into the fan-shaped test box through the atomizing nozzle, and observe and record the survival situation of the previous test insects through the fan-shaped test box before the next insect supply.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. Through the design of the fan-shaped test box, atomizing nozzle and control valve, the present invention enables testers to simultaneously conduct toxicity assays on different concentrations of the same medicament, improving the toxicity assay efficiency and shortening the test cycle. Thus, it solves the problem in the prior art that automatic large-batch toxicity assays cannot be carried out for control medicaments of different concentrations. It can also be configured to conduct toxicity assays on different medicaments, increasing the practicality of the equipment.

[0024] 2. In the present invention, a driving member drives a rotating shaft to rotate, driving a long gear fixedly and coaxially fitted with the same rotating shaft to rotate. The rotation of the long gear drives a first gear to rotate, and the first gear drives other long gears to rotate. The long gear meshes with the rack to drive multiple fan-shaped collection boxes to slide out or slide in simultaneously, not only improving the convenience of use but also maintaining the relative fixation of the position to avoid confusion.

[0025] 3. When the intermittent insect supply module is in the initial working state, the first baffle blocks the bottom of the insect release groove, so that the insect release groove is not communicated with the fan-shaped test box, and the second baffle does not block the communication between the insect release groove and the insect box. By opening the switch assembly, enough whiteflies required for the test are put into the insect box. The switch assembly is closed, and the insect-attracting lamp on the inner side wall of the insect release groove is turned on. By controlling the intermittent driving assembly to drive the second retaining ring to rotate, the second baffle is driven to block the bottom of the insect box, so that the insect release groove is not communicated with the insect box. The intermittent driving assembly continues to rotate, causing the first retaining ring to rotate and drive the first baffle not to block the bottom of the insect release groove. At this time, the insect-attracting lamp is in the off state, and the whiteflies are sent into the fan-shaped test box. The intermittent driving assembly rotates in the reverse direction, successively causing the first baffle to block the bottom of the insect release groove and the second baffle not to block the bottom of the insect box. At this time, the control valve is opened to spray the configured medicament through the atomizing nozzle, enabling the collected whiteflies to be intermittently and automatically fed into the fan-shaped test box in batches. This not only ensures the continuity of the toxicity assay without manual intervention and reduces the safety risk but also solves the problem that putting in too many at one time is likely to lead to inaccurate test results and is not conducive to observing and analyzing the reaction and change of whiteflies to different concentrations of the medicament.

[0026] 4. In the present invention, by controlling the deployment driving member to drive the third gear to rotate, the third gear meshes with the toothed rings on both the large turntable and the small turntable for transmission. At this time, the large turntable and the small turntable rotate in opposite directions, driving the rotating cylinder and multiple stirring columns to rotate in different directions, which can uniformly stir the raw medicine within a short time, improving the stirring efficiency and enhancing the mixing effect. By starting the water pump and the liquid pump simultaneously, the water pump pumps the water in the water tank into the conveying channel through a pipeline, and the liquid pump sends the medicine in the medicine preparation tank into the conveying structure. Through the concentration ratio component, the medicine and water are configured into the concentration gradient required for the experiment and are respectively conveyed into the medicine-containing bottles in each sector-shaped test box. Each electric valve on each configuration pipe is opened, and according to the instructions of the water flow meter on each water delivery pipe and the medicine flow meter on each medicine delivery pipe, the water flow in the water delivery pipe and the medicine flow in the medicine delivery pipe are controlled to reach the concentration gradient ratio required for the experiment and are conveyed into each medicine-containing bottle. During the configuration process, the electric valves in each configuration pipe are automatically closed according to the actual situation, and an accurate concentration gradient ratio can be obtained, thus solving the problem that a large number of concentration gradients in medicine preparation are prone to confusion.

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0035] Please refer to Figures 1 - 6 , the present invention provides a technical solution: a virulence determination test system for a Bemisia tabaci control agent, including:

[0036] A medicine dispensing mechanism 1 and a testing mechanism 2, the medicine dispensing mechanism 1 is used for dispensing medicine and conveying it to the testing mechanism 2;

[0037] The testing mechanism 2 includes a support arm 21, an annular testing box 22 fixedly engaged with the support arm 21, a medicine bottle 23, an atomizing nozzle 24, a sector-shaped collection box 25, a collection driving module 26, and an intermittent insect supply module 27. The annular testing box 22 includes a plurality of sector-shaped testing boxes 221, and the plurality of sector-shaped testing boxes 221 are spliced to form the annular testing box 22. Both the sector-shaped collection box 25 and the sector-shaped testing box 221 can be made of borosilicate glass material. The borosilicate glass material has properties such as high transparency, easy cleaning, oil resistance, acid and alkali resistance, etc., and is also convenient for observing the test situation at any time. A medicine bottle 23 is fixedly connected to the top end inside the sector-shaped testing box 221. A sector-shaped collection box 25 is slidably arranged at the bottom of the sector-shaped testing box 221. The medicine outlet end of the medicine bottle 23 is connected to a spray pipe 28, and the end of the spray pipe 28 is connected to an atomizing nozzle 24. Control valves 29 are arranged outside the spray pipe 28.

[0038] It should be noted that through the design of the sector-shaped testing box 221, the atomizing nozzle 24, and the control valve 29, the test personnel can simultaneously conduct virulence determination on different concentrations of the same medicament, improving the virulence determination efficiency and shortening the test cycle. Thus, the problem in the prior art that the virulence of different concentrations of control medicaments cannot be automatically determined in large quantities is solved. Different medicaments can also be configured for virulence determination, increasing the practicality of the equipment.

[0039] A collection driving module 26 for controlling the opening and closing of the sector-shaped collection box 25 is arranged at the bottom of the sector-shaped collection box 25, and an intermittent insect supply module 27 for intermittently supplying insects into the sector-shaped testing box 221 is arranged at the top of the annular testing box 22.

[0040] It should be noted that the collection driving module 26 controls the opening and closing of multiple sector-shaped collection boxes 25. Through the design of the collection driving module 26, not only the convenience of use is improved, but also the relative position can be kept fixed to avoid confusion. The intermittent insect supply module 27 intermittently supplies insects into the sector-shaped testing box 221, and can continuously and automatically send the collected whiteflies into the sector-shaped testing box 221 in batches at intervals. This not only ensures the continuity of virulence determination without manual intervention and reduces safety risks, but also solves the problem that putting in too many at one time is likely to lead to inaccurate test results and is not conducive to observing and analyzing the reaction and change of whiteflies to different concentrations of medicaments.

[0041] The medicine preparation mechanism 1 includes a medicine preparation box 11, a preparation module 12, and a conveying and proportioning module 13. A feeding port 111 is arranged on the side wall of the medicine preparation box 11. A preparation module 12 is arranged inside the medicine preparation box 11. A conveying and proportioning module 13 for conveying the medicine evenly mixed by the preparation module 12 in the medicine preparation box 11 into the medicine bottle 23 is arranged outside the medicine preparation box 11.

[0042] It should be noted that through the design of the dispensing module 12 and the conveying and proportioning module 13, the original drug can be evenly mixed in the medicine dispensing box 11 and automatically configured into the concentration gradient required for the test, thus solving the problem that multiple concentration gradients in medicine dispensing are likely to cause confusion.

[0043] Please refer to Figures 1 - 3 , the collection driving module 26 includes a support disk 261 fixedly fitted with the support arm 21, a rotating shaft 262, a long gear 263, a rack 264, a first gear 265 and a collection driving member 266. A first gear 265 is rotatably provided at the top of the support arm 21. Rotating shafts 262 are equidistantly rotatably provided at the top of the support disk 261. A collection driving member 266 for controlling the rotation of the rotating shaft 262 is provided at the bottom of the support disk 261. A long gear 263 is fixedly connected to the top end of the rotating shaft 262. A rack 264 is fixedly connected to the bottom of the annular test box 22. The top end and the bottom end of the long gear 263 are respectively meshed and connected with the rack 264 and the first gear 265.

[0044] It should be noted that the collection driving member 266 includes a motor, and the motor can be controlled wirelessly. By using a wireless communication module to send a control signal to the motor, the motor can be controlled to work, making the motor control more flexible and convenient. During operation, the collection driving member 266 drives a rotating shaft 262 to rotate, driving the long gear 263 fixedly fitted coaxially with the same rotating shaft 262 to rotate. The rotation of the long gear 263 drives the first gear 265 to rotate, and the first gear 265 drives other long gears 263 to rotate. The meshing transmission between the long gear 263 and the rack 264 drives multiple sector-shaped collection boxes 25 to slide out or slide in simultaneously, which not only improves the convenience of use but also can keep the relative position fixed to avoid confusion.

[0045] Please refer to Figure 3 and Figure 4, the intermittent insect supply module 27 includes an annular block 271, an insect box 272, a first retaining ring 273, a first baffle 274, a second retaining ring 275, a second baffle 276, a switch assembly 277 and an intermittent drive assembly 278. The annular block 271 is fixedly connected to the top of the annular test box 22, and the insect box 272 is fixedly connected to the top of the annular block 271. The end of the support arm 21 is rotatably connected to the first retaining ring 273, and the first baffles 274 are equidistantly arranged on the outer side of the first retaining ring 273. The second retaining ring 275 is rotatably arranged on the outer side of the support arm 21 away from the first retaining ring 273, and the second baffles 276 are equidistantly arranged on the inner wall of the second retaining ring 275. A switch assembly 277 for controlling the opening and closing of the insect box 272 and an intermittent drive assembly 278 for controlling the rotation of the second retaining ring 275 are arranged on the outer side of the support arm 21. The annular block 271 includes a plurality of sector blocks 2711, and the plurality of sector blocks 2711 are spliced to form the annular block 271. The sector blocks 2711, the second retaining ring 275 and the central axis of the support arm 21 are collinear. The sector blocks 2711 and the insect box 272 can both be made of borosilicate glass material, which has the properties of high transparency, easy cleaning, oil resistance, acid and alkali resistance, etc., and is also convenient for observing the survival situation of the whitefly at any time. A first chute 27111 for the first baffle 274 to slide is provided at the bottom of each sector block 2711. A worm releasing groove 27112 communicating the sector test box 221 and the insect box 272 is provided on each sector block 2711. An insect attracting lamp is provided on the inner side wall of each worm releasing groove 27112. The insect attracting lamp is only turned on when the worm releasing groove 27112 is communicated with the insect box 272. A second chute 2721 is provided on the side wall near the bottom of the insect box 272. The second chute 2721 is slidably matched with the second baffle 276 and corresponds to each other one by one;

[0046] A first chute 27111 for the first baffle 274 to slide is provided at the bottom of the sector block 2711. A worm releasing groove 27112 communicating with the annular test box 22 and the insect box 272 is opened at the top of the sector block 2711. An insect attracting lamp is provided on the inner wall of the worm releasing groove 27112. A second chute 2721 is opened at the bottom end of the inner wall of the insect box 272. The second baffle 276 is slidably arranged in the second chute 2721.

[0047] It should be noted that in the initial working state of the intermittent insect supply module 27, the first baffle 274 blocks the bottom of the insect release slot 27112, so that the insect release slot 27112 is not connected to the fan-shaped test chamber 221. The second baffle 276 does not block the connection between the insect release slot 27112 and the insect box 272. By opening the switch assembly 277, enough whiteflies required for the test are put into the insect box 272. Then the switch assembly 277 is closed, and the insect attracting lamp on the inner side wall of the insect release slot 27112 is turned on. By controlling the intermittent drive assembly 278 to drive the second retaining ring 275 to rotate, the second baffle 276 is driven to block the bottom of the insect box 272, so that the insect release slot 27112 is not connected to the insect box 272. The intermittent drive assembly 278 continues to rotate, causing the first retaining ring 273 to rotate and drive the first baffle 274 not to block the bottom of the insect release slot 27112. At this time, the insect attracting lamp is in the off state, and the whiteflies are sent into the fan-shaped test chamber 221. The intermittent drive assembly 278 rotates in the reverse direction, successively causing the first baffle 274 to block the bottom of the insect release slot 27112 and the second baffle 276 not to block the bottom of the insect box 272. At this time, the control valve 29 is opened and the prepared medicament is sprayed through the atomizing nozzle 24, so that the collected whiteflies can be continuously and intermittently and automatically sent into the fan-shaped test chamber 221 in batches. This not only ensures the continuity of the toxicity determination without manual intervention and reduces the safety risk, but also solves the problem that putting in too many at one time is likely to lead to inaccurate test results and is not conducive to observing and analyzing the reaction and change of whiteflies to different concentrations of the medicament.

[0048] Please refer to Figure 4 , the switch assembly 277 includes a 7-shaped blocking plate 2771, an elastic member 2772, a blocking groove 2773 and a pin shaft 2774. A 7-shaped blocking plate 2771 is arranged in the insect box 272. An elastic member 2772 for resetting the 7-shaped blocking plate 2771 away from the support arm 21 is arranged outside the support arm 21. A blocking groove 2773 cooperating with the 7-shaped blocking plate 2771 is formed on the surface of the insect box 272. A pin shaft 2774 is arranged at the top of the 7-shaped blocking plate 2771, and the two ends of the top of the 7-shaped blocking plate 2771 are rotatably connected to the inner wall of the blocking groove 2773 through the pin shaft 2774.

[0049] It should be noted that the elastic member 2772 includes springs. There are two springs. One end of each of the two springs is fixedly connected to the side surface close to the bottom of the vertical part of the 7-shaped blocking plate 2771 and close to the support plate arm, and the other end of each of the two springs is fixedly connected to the inner side wall of the insect box 272. When putting whiteflies into the insect box 272, the 7-shaped blocking plate 2771 is pushed towards the support arm 21 to place the whiteflies. At this time, the springs are in a stretched state. After the placement is completed, under the action of the spring force, the 7-shaped blocking plate 2771 can quickly return to the initial position, which can effectively prevent the whiteflies from escaping and reduce the work intensity of the test personnel.

[0050] Please refer to Figure 4, the intermittent drive assembly 278 includes a rotating disk 2781, a 7-shaped frame 2782, a second gear 2783, a rotating column 2784, a disk 2785, an arc-shaped rack 2786, an internal gear ring 2787, and an intermittent drive member 2788. The top of the support arm 21 is rotatably installed with the rotating disk 2781, and the outer side of the rotating disk 2781 is equidistantly fixedly connected with the 7-shaped frame 2782. The bottom end of the 7-shaped frame 2782 is fixedly connected with the internal gear ring 2787. The outer side of the support arm 21 is fixedly installed with the second gear 2783, and the second gear 2783 is located inside the internal gear ring 2787. The arc-shaped racks 2786 are meshed and connected with both the internal gear ring 2787 and the second gear 2783.

[0051] It should be noted that during operation, the intermittent drive member 2788 is controlled to drive the disk 2785 to rotate. The arc-shaped rack 2786 coaxially and fixedly fitted on the outer wall of the disk 2785 drives the internal gear ring 2787 to rotate. The internal gear ring 2787 drives the second retaining ring 275 to rotate. The second baffle 276 slides in the second chute 2721 to block the insect-releasing slot 27112 and the insect box 272. The intermittent drive member 2788 continues to rotate, and the arc-shaped rack 2786 coaxially and fixedly fitted on the outer wall of the disk 2785 meshes with the second gear 2783 for transmission. The second gear 2783 rotates to drive the rotating column 2784 to rotate. The rotating column 2784 rotates to drive the first retaining ring 273 to rotate. The first baffle 274 slides in the first chute 27111 to connect the insect-releasing slot 27112 with the sector-shaped test box 221. At this time, the whiteflies enter the sector-shaped test box 221 from the insect-releasing slot 27112. The intermittent drive member 2788 reverses to successively cause the first baffle 274 to block the bottom of the insect-releasing slot 27112 and the second baffle 276 not to block the bottom of the insect box 272. The whiteflies in the insect box 272 enter the insect-releasing slot 27112 to prepare for repeated experiments. Thus, it not only ensures the continuity of the toxicity determination without manual intervention and reduces the safety risk, but also solves the problem that putting in too many at one time is likely to lead to inaccurate test results and is not conducive to observing and analyzing the reaction and change of whiteflies to different concentrations of the medicament.
