Problems solved by technology

In order to better observe the wing veins of insects, it is necessary to remove the densely covered scales on the wings of insects and make specimens for easy observation. Since the wings of Lepidoptera insects are thin and brittle, physical methods such as soaking, drifting, and brushes should be used to observe the veins of insect wings. Methods such as brushing off scales are easy to damage the wing veins, and the operation is complicated and difficult to meet the requirements of use. Therefore, chemical agents are often used to remove scales from insect wing veins.
[0003] At present, the existing insect wing vein scale removal agents mainly contain xylene, alcohols, strong acids (hydrochloric acid, etc.) It has certain toxicity and is flammable, which has certain dangers in use; the fins treated with alcohol are easy to be damaged, and the integrity of the fins cannot be well preserved; strong acid or strong alkali is not only difficult to configure and use, but also Threat to the work safety of users
The invention patent with the patent application number CN105427728A discloses a method for removing scales from the wing surfaces of Lepidoptera insects, which discloses a method of using ethanol, glycerin, sodium hydroxide and sodium hypochlorite to treat the wing surfaces of Lepidoptera insects to remove scales , which uses ethanol as a fixative, glycerin as a softener, sodium hydroxide and sodium hypochlorite as an oxidizing agent and a reaction treatment agent, but this method needs to configure a variety of agents for use, the operation is very unchanged, and the raw materials used also include hydroxide Sodium, a strong base that is harmful to experimenters, is not conducive to work safety

preparation example Construction

[0031] The present invention also provides a preparation method of the insect specimen descaling agent, which includes the following steps: drop the epoxy resin into the modified amine and stir evenly. Preferably, the epoxy resin is dropped into the modified amine stirred at 30-60 r / min; more preferably, the epoxy resin is dropped into the modified amine at a speed of 4-8 drops / Sec.

[0032] The preparation method of the insect specimen descaling agent provided by the present invention is to slowly drop the epoxy resin into the modified amine stirred at a medium speed, so that the epoxy resin can shrink at a certain curing rate, so that the epoxy resin can be fully utilized. The adhesive force generated when the resin cures and shrinks removes the scales on the fins of the insect specimens and avoids damage to the fins. The preparation method has the advantages of simple process and convenient operation.

[0033] The present invention also provides a method for removing scales...

Embodiment 1

[0038] The present embodiment provides a method for removing insect specimen scales, which mainly includes the following steps:

[0039] S11. Prepare an insect specimen descaling agent: add 1 g of epoxy resin to 9 g of modified amine and stir evenly to obtain an insect specimen descaling agent.

[0040] S12. Put the insect fins into the prepared insect specimen descaling agent and soak for 1 min, then take them out.

Embodiment 2

[0042] The present embodiment provides a method for removing insect specimen scales, which mainly includes the following steps:

[0043] S21. Prepare an insect specimen descaling agent: add 8 g of epoxy resin at a rate of 4 drops / sec to 42 g of modified amine stirred at 50 r / min and stir evenly to obtain an insect specimen descaling agent.

[0044] S22. Soak the insect fins in salt water with a mass percentage of 10% sodium chloride for 10 minutes, then put them into the insect specimen descaling agent prepared above for 1 minute and take them out.

Abstract

The invention discloses a scale remover for an insect specimen, a preparation method thereof and a scale removal method of the insect specimen, and belongs to the technical field of specimen making. The scale remover for the insect specimen is prepared and obtained from the following raw materials: epoxy resin and modified amine. The scale remover for the insect specimen is wide in source of preparation raw materials and further has a little harm to a user. The scale remover for the insect specimen is prepared and obtained by adopting the epoxy resin and the modified amine as the raw materials. The invention also provides the preparation method of the scale remover for the insect specimen. The preparation method comprises the following step of dropwise adding the epoxy resin into the agitated modified amine. The preparation method has the advantages of being simple in process and convenient to operate. The invention also provides the scale removal method of the insect specimen. The method can be used for quickly and efficiently removing a scale on a fin of an insect, and further has the advantages of being good in elution effect and having no the residue of a sticking substance onthe fin after elution.

Description

technical field [0001] The invention relates to the technical field of specimen production, and in particular to an insect specimen descaling agent, a preparation method thereof and a method for removing insect specimen scales. Background technique [0002] Insect wing veins are one of the main bases for insect classification, and it is especially common to use wing veins as a basis for the classification of Lepidoptera insects. In order to better observe the wing veins of insects, it is necessary to remove the densely covered scales on the wings of insects and make specimens for easy observation. Since the wings of Lepidoptera insects are thin and brittle, physical methods such as soaking, drifting, and brushes should be used to observe the veins of insect wings. Methods such as brushing off scales are easy to damage wing veins, and the operation is complicated and difficult to meet the requirements of use.
