Embodiment 1

[0036] 1) Weigh 139g of potassium carbonate and dissolve it in 100ml of deionized water at 80°C, stir to accelerate the dissolution, then cool to room temperature, and prepare a saturated potassium carbonate solution;

[0037] 2) Weigh 10g of carboxymethyl chitosan, put 90ml of deionized water into a 200ml beaker, stir with a glass rod for 3 minutes, and then ultrasonically disperse in a CNC ultrasonic cleaner for 15 minutes to fully disperse and dissolve A carboxymethyl chitosan solution with a mass fraction of 10% was formed.

[0038] 3) Weigh 1g of dopamine hydrochloride, measure 99ml of deionized water and 10 mM Tris-buffer buffer solution, mix them in a 200ml beaker, adjust the pH to 8.5, and stir slowly for 48 hours to form a polydopamine solution.

[0039] 4) Pour the solutions in step 2) and step 3) into the reaction bottle and place it in an ice-water bath. Weigh 40g of acrylamide, 3mg of N,N'-methylenebisacrylamide, 5mg of ammonium persulfate and 20 μL of tetramethy...

Abstract

The invention relates to the technical field of specimens, in particular to a vacuum storage method for insect specimens. According to the vacuum storage method, non-woven fabric adsorbed with an antibacterial agent is added into an insect specimen box to achieve the bacteriostatic effect, modified hydrogel with a humidifying function is heat-sealed in the non-woven fabric, and then the insect specimens are boxed. According to the vacuum storage method, a vacuum sealing technology is applied to preservation of the insect specimens, the method has extremely high application value in transportation and storage of the insect specimens, and the preservation performance of the insect specimens is very excellent when the insect specimens are subjected to vacuum sealing preservation.

Description

technical field [0001] The invention relates to the technical field of specimens, in particular to a vacuum storage method for insect specimens. Background technique [0002] There are about 1 million species of insects known in the world, accounting for more than 70% of the species in the entire animal kingdom. Hundreds of millions of years ago, countless insects were preserved and continued to this day in the form of fossils. Insect fossils can not only preserve the original morphological characteristics of insects, but also record the internal genes of insects. In recent years, the rapid development of entomology, ecology, biochemistry, pharmacology and other disciplines has further promoted the development and utilization of insect resources. As an important part of biological resources, insect specimens are the basic materials for animal and plant quarantine, pest control and other research and course teaching. [0003] However, after the insect specimens are prepa...
