Description

Technical Field

[0001] The utility model belongs to the technical field of insect immersion bioassay, in particular to an insect body clamping device for insect immersion bioassay. Background Art

[0002] The insect immersion method is the primary method for determining contact toxicity in insecticide bioassays. Currently, the method commonly used in scientific research involves placing insects in a immersion cage and immersing them in the insecticide for 5-10 seconds. The insecticide's surface is then blotted with absorbent paper to observe insect mortality and determine efficacy. However, due to the large size and irregular shape of the immersion cages, the immersion process often requires a larger container to fully immerse the cages. This results in high drug consumption, waste, and environmental pollution.

[0003] After the insect immersion is completed, it is required to immediately absorb the moisture on the surface of the insect body. However, because the insect immersion cage needs to be opened and the insects need to be taken out one by one, it is impossible to absorb the moisture of the insect body in time, resulting in different lengths of time the insect body is exposed to the agent, increasing the experimental error, and in severe cases, leading to the failure of the experiment.

[0004] The immersion bioassay requires the test insects to be immersed in a drug solution for 5 seconds. Currently, immersion cages are often used for these experiments. These experiments are cumbersome, require large amounts of drug solution, and have difficulty controlling the contact time between the insects and the solution. Furthermore, the cages are difficult to clean, which can easily lead to cross-contamination. Currently, there is a lack of a simple, easy-to-clean, drug-saving, and precisely controlled contact time tool for holding the insects in the immersion bioassay.

[0005] Therefore, there is an urgent need for a simple insect body clamping device that can improve insect soaking efficiency, reduce the amount of medicine used, and avoid errors in soaking time. Utility Model Content

[0006] In order to solve the problems raised in the above background technology, the utility model provides an insect body clamping device for insect immersion biological assay, which is used to solve the problem that there is no simple clamping device for insect immersion assay.

[0016] 3. The pressure spring device can automatically open the cover. Press it down hard during use, and it will automatically rebound after the experiment, which is in line with human working habits.

[0017] 4. The metal cover can be placed with special absorbent paper to absorb moisture directly from the insect surface after soaking the insects;

[0018] 5. Using isolation boards to evenly disperse the space, 9 worms can be tested in one experiment, reducing the number of experiments and increasing the repetition rate;

[0019] 6. The main body of the device is relatively small, and the requirements for the insect bioassay experimental solution and container are low. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Working principle and process:

[0033] The insect body clamping device features a removable 60-mesh wire mesh insect grid 3, which contains four internal isolation panels 4, dividing the interior space into nine sections. The 60-mesh wire mesh insect grid 3 is placed within a hollow square ring 2, and a metal hook 10 is pulled to hook onto a D-shaped ring 12. The 60-mesh wire mesh insect grid 3 is sealed and immersed in the drug solution. After the 60-mesh wire mesh insect grid 3 is extracted from the drug solution, absorbent paper is placed on the metal cover 1, and the metal hook 10 is released, retrieving the 60-mesh gauze 13 and returning it to the gauze roll 11. The clamping device is inverted, and the handle 7 is gripped to compress the pressure spring 8, closing the metal cover 1 via the pin 6. The insects fall from the 60-mesh wire mesh insect grid 3 onto the absorbent paper, which is then manually wiped to remove moisture from the insect's surface. This clamping device solves the problems of large drug dosages, delayed insect absorption, and inconvenient cage cleaning in insect immersion bioassay experiments, reducing drug waste and experimental errors, while improving experimental accuracy. The utility model has the advantages of simple structure, low cost, convenient use, simple cleaning, and the ability to avoid cross contamination and reduce experimental errors in insect bioassays, and is suitable for popularization and use.
