Problems solved by technology

However, harmful reagents such as formaldehyde are used in the preparation of the specimens. The specimens cannot be directly contacted and observed, and the specimens are not easy to preserve. The amber should be stored in a special specimen box and avoid contact with strong acids. , strong alkali, not heavy pressure, keep the air dry

Embodiment Construction

[0036] The present invention will now be further described in conjunction with specific embodiments.

[0037] (1) Larval specimen preparation:

[0038] (1) Select the larvae of the right age, and kill them by quick freezing;

[0039] (2) Heat the color-preserving reagent to 80°C to melt, and when cooled to 70-75°C, soak the insect body in the solution for 20 minutes, and then clean the surface of the insect body with distilled water;

[0040] (3) Soak the insects in 50% polyethylene glycol with a molecular weight of 400 for two hours, and turn the insects every half an hour to keep the surface of the insects in uniform contact with polyethylene glycol with a molecular weight of 400. After taking them out, wipe them clean with absorbent paper ;

[0041] (4) Heat the polyethylene glycol filling reagent until it is completely melted, moisten the syringe, and use the syringe to draw a small amount of the filling reagent and inject it from the tail corner of the worm body until ...

Abstract

The invention discloses a manufacturing technology of lepidopteron plastinated specimens. By the method for manufacturing specimens, instruments and equipment used are simple. A constant temperature incubator is only needed for a simple drying treatment, and vacuum drying and pressure infiltration processing are not required. Plastification time is shortened. The manufacturing process is simpler and easier to do. Reagents which are harmful to human body are not used during the manufacturing process. Manufactured specimens can directly be contacted. External morphology, especially scale, is not influenced. Manufactured specimens can be widely applied in teaching, scientific research and collection and display. According to plastinated specimens of butterflies (such as papilionoidea, brush-footed butterflies and Pieridae), phalaenae (such as tussah and silkworm) and the like which are manufactured by the above technology, scale is maintained perfect, forms are lifelike, and the color of larva is very similar to that of a living body.

Description

technical field [0001] The invention relates to a technique for making specimens, more specifically, to a method for making plasticized specimens of Lepidoptera insects. Background technique [0002] At present, the methods for preparing Lepidoptera insect specimens mainly include wing spreading method and artificial amber technology. [0003] The preparation of wing-spread specimens is to select a suitable wing-spreading plate when the body of the Lepidoptera insect is soft before it is dry, pick the insect with tweezers, place it on the wing-spreading plate, select an appropriate insect needle or pin, and insert it from the middle chest or back of the insect. The center of the chest is inserted vertically. Use a long piece of smooth and transparent soft paper to press on the wings, and nail the pins to fix the wings. After drying thoroughly, take them out and store them in the specimen box for a long time. The advantage of spread-wing specimens is that it is easy to prep...
