Problems solved by technology

The sealing method of the test tube is plug sealing or cap sealing, that is, the appropriate cotton plug, wooden stopper, rubber stopper or matching bottle cap is selected for sealing, and the sealing part is further sealed with adhesive such as silica gel. Although this method is convenient to operate, the specimen preservation The time is not long, the seal is easy to leak
In addition, some sealers are used for sealing, but the operation is complicated, the maintenance cost is expensive, and it is not easy to promote

Embodiment 1

[0057] 1. Preliminary preparation of insect test tube specimens

[0058] (1) Physical specimens and processing

[0059] Select test tubes of different specifications and models according to physical specimens (such as eggs, larvae, pupae of insects, and some smaller adults).

[0060] Because the flame of the alcohol blowtorch is around 20mm, the diameter of the test tube should be ≤18mm, generally 10-15mm. If the diameter is too large, the tube wall will be heated unevenly.

[0061] The wall thickness of the test tube is ≤1.5mm. If the tube wall is too thick, it will make it difficult to rotate and stretch, and if the burning point is too thick, it will easily lead to cracking at the burning point during cooling. The wall thickness of the test tube is preferably 1.0-1.5mm It is advisable, this is because the tube wall is too thin, the test tube is easily damaged, and it is not easy to preserve.

[0062] Test tubes with a diameter of 10-13mm, the tube length is not less than ...

Embodiment 2

[0092] The difference between embodiment 2 and embodiment 1 is that during the trial screwing and screwing process, the hand wears heat-insulating safety gloves; and the shape of the spiral seal can be other shapes, which can be nearly conical or long cylindrical.

Embodiment 3

[0094] The difference between embodiment 3 and embodiment 1 is that the vise is replaced with a heat-resistant clamping device, including needle-nose pliers and iron clamps; the heating device (alcohol blowtorch) is replaced with other heating devices that can reach the same softening effect Including oxygen spray gun, butane spray gun, liquefied gas spray gun.

Abstract

The invention provides a simple insect specimen making method. The method comprises the following steps of: S1, the early-stage preparation of an insect test tube specimen, S2, the calcination of theinsect test tube specimen; and S3, the maintenance and preservation of the insect test tube specimen. According to the method of the invention, an ordinary glass test tube is softened by using the high temperature of an alcohol blast burner; the test tube is tightened and closed by using a vice, and therefore, the test tube can be made with simplicity and easiness. The simple insect specimen making method has the advantages of simplicity and easiness in preparation and low cost. With the simple insect specimen making method adopted, the insect specimen can be obtained easily; the specimen is completely sealed, can be stored for a long time; the storage environment of the specimen is simple and has no special requirements; the specimen can be stored in a cool place at normal temperature; the management cost of the specimen is low; once made, the specimen can be completely preserved, has little possibility of being damaged, can be transferred conveniently; the making procedures of the specimen are simple and easy; and operation is convenient and easy to learn. The simple insect specimen making method is suitable for being popularized in enterprises and public institutions, universities and research institutes related to agriculture and forestry, and is more suitable for being used by grass-roots agriculture and forestry employees.

Description

technical field [0001] The invention belongs to the technical field of experimental instruments, and in particular relates to a simple method for making insect specimens. Background technique [0002] The production of insect specimens has always been one of the important tasks of agricultural and forestry practitioners, especially universities or research institutes engaged in the study of insect taxonomy. At present, the conventional insect specimen preparation method is mostly the soaking method. [0003] The test tube specimen method is one of the immersion methods, that is, the test tube is filled with a physical specimen and a preservation solution, and then the test tube is sealed. The commonly used test tubes are mostly glass test tubes. The sealing method of the test tube is plug sealing or cap sealing, that is, the appropriate cotton plug, wooden stopper, rubber stopper or matching bottle cap is selected for sealing, and the sealing part is further sealed with adh...
