Description
Technical Field
[0001] This utility model relates to the technical field of experimental equipment for tube-based drug film testing, and more specifically to a special device for tube-based drug film testing suitable for micro-sized phototactic parasitic wasps. Background Technology
[0002] Microparasitic wasps have a wide host range and play a role in the biological control of various agricultural and forestry pests. In the field, the microparasitic wasps are mainly released through flooding to control target pests. The survival rate of the adult wasps after emergence in the field directly affects the final control effectiveness.
[0003] In field pest control practices, chemical pesticides and biological pesticides are widely used. However, while some insecticides effectively kill target pests, they inevitably have varying degrees of negative impact on natural enemies of pests and other non-target organisms. Currently, the safety of these pesticides on parasitic wasps requires further investigation.
[0004] To assess the safety of different pesticides to microparasitic wasps, the contact toxicity of the pesticides is typically determined using the tube test for pesticide film toxicity. The experimental procedure of this method mainly includes the following steps:
[0005] Emergence stage: The parasitic wasp larvae are placed in the first glass tube (emergence tube) to allow them to successfully complete the entire emergence process.
[0006] Drug film preparation: Prepare the drug to be tested into a drug solution, and evenly spread the drug solution on the inner wall of the second glass tube (drug film tube) by rolling. Pour out the drug solution and air dry the drug film tube in a cool place.
[0007] Phototaxis guidance: Utilizing the phototaxis of parasitic wasps, the parasitic wasps in the eclosion tube are guided into the drug film tube by a light source.
[0008] Transfer of surviving bees: After the set crawling time is over, the parasitic bees surviving in the drug-coated tube are guided by phototaxis into the third glass tube (without drug).
[0009] However, the tube-based drug film testing method currently lacks dedicated equipment, requiring the use of multiple glass test tubes. During the experiment, it is necessary to frequently connect and transfer the parasitic wasps, requiring a significant amount of time to practice and master the operating techniques. Furthermore, it is easy for the parasitic wasps to escape or be damaged, reducing the success rate of the experiment and increasing experimental errors.
[0010] Therefore, providing a dedicated device for tube-based drug film testing of micro-sized phototactic parasitic wasps is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

It includes a column 1 and, from top to bottom, a light source module 2, an upper quick-release gripper 3, a gate sealing module 4, and a lower quick-release gripper 5, all mounted sequentially on the column 1. This utility model utilizes the phototactic characteristics of parasitic wasps, employing a light source to induce directional transfer of the wasps, achieving rapid and non-damaging transfer of the wasps between different test tubes, reducing escape rates. Combined with an adjustable docking module, it not only effectively controls the escape rate of the wasps during the transfer of drug film tubes but also adapts to glass test tubes of different diameters and heights, thereby comprehensively improving the reliability and accuracy of the experiment.
[0039] In this embodiment, column 1 is cylindrical.
[0040] Specifically, the upper quick-release clamp 3 and the lower quick-release clamp 5 have the same structure, both including a clamp 31, a clamp bolt 32 and a clamp nut. The closed side of the clamp 31 is mounted on the column 1 by the first fixing clamp 6, and the open side of the clamp 31 is fastened by the clamp bolt 32 that passes through it and the clamp nut screwed on the clamp bolt 32. Thus, rotating the nut can expand or tighten the clamping range to accommodate test tubes of different diameters (8mm-15mm).
[0041] To further optimize the technical solution of this utility model, the clamping surface of the gripper 31 is provided with anti-slip silicone texture 311; or the clamping surface of the gripper 31 is covered and fixed with an anti-slip silicone pad. This is used to wrap and fix the test tube, ensuring clamping stability. In this embodiment, the anti-slip silicone texture 311 is a prismatic raised structure with a height of 0.3mm.

The gate plate 42 is slidably connected to the gate body 41, and the bottom of the gate plate 42 has a sealing groove 421. The sealing ring 43 is installed in the sealing groove 421. The handle 44 is fixed to the extended end of the gate plate 42. In this embodiment, the handle 44 is trapezoidal, and the gate plate 42 can be pulled out by the handle 44.
[0043] Specifically, the gate body 41 has slide rails 411 on its inner walls on both sides; the gate plate 42 has ball sliders on both sides, which are fitted into the slide rails 411 and slidably connected.

[0045] Specifically, the light source module 2 includes a lampshade 21, multiple LEDs 22, and a touch-sensitive switch 23.

In this embodiment, the substrate integrates white LED chips with various color temperatures (such as 2700K, 4000K, and 6500K), and the control circuit controls their driving currents respectively. By adjusting the current ratio of different LED chips, light of different color temperatures can be synthesized and output, thereby achieving color temperature adjustability. By adjusting the color temperature, it can meet the experimental needs of parasitic wasps with different phototactic behaviors. The touch-sensitive switch 23 is installed on the lampshade 21 and is electrically connected to multiple LEDs 22. The color temperature of the light source can be adjusted by touching the sensing surface.
