Background
Insects are closely related to the life of human beings, and the known insects are 100 thousands of insects. In order to make people more convenient to research, study and appreciate insects, the insects are made into insect specimens so as to be stored for a long time, and meanwhile, the insect specimens are important basis for determining insect species and are fresh and alive teaching materials for knowing the insects. In addition, for the whole life history of the insect, people are required to know the habits and the forms of the adult insect and the living states of the insect larvae, so that worm-shaped insect larva specimens are prepared, and precious data are left for subsequent scientific research. For people to study, study and appreciate.
The existing insect specimen manufacturing and displaying method is manufactured based on adult insects, few specimens of insect larvae exist, even larva specimens are basically preserved in alcohol, and the larva specimens are soaked in the alcohol for a long time to cause the larva to decolor and deform, so that the original morphological characteristics are lost, and people can not clearly know the life history of the insects.
In addition, in the process of manufacturing insect specimens, most of the insect specimens are only roughly spread wings, adjusted in posture and air-dried, and the insects are not carefully dissected and preserved, so that the specimens cannot be stored for a long time, and a great deal of waste of resources is caused.
Through the analysis, the insect specimen preparation method in the prior art has a great deal of resource waste and larva requirements.

The method for manufacturing the vermicular insect larva specimen is applied to displaying and storing the vermicular insect larva specimen.
Has the advantages that:
the invention provides a method for manufacturing a vermicular insect larva specimen, which effectively stores and displays vermicular insect larvae, makes up for the vacancy of the vermicular insect larva specimen and has important significance for the exploration of insect teaching time and insect life history. In addition, the insect larva filling material is crystal mud and gelatin, is easy to operate, high in reduction degree, low in cost, environment-friendly and convenient to transport, is different from traditional insect specimens, and is more suitable for teaching practice.
Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the embodiments of the present invention, and it is obvious that the described embodiments are some embodiments of the present invention, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
A method for preparing the specimen of worm-shaped insect larva features that the auxiliary tool and colorless filler colloid are used to replace the content of worm-shaped insect larva, and the treated worm-shaped insect larva is stored in specimen box.
The method specifically comprises the following steps:
s1: physically removing the contents in the body of the vermiform insect larvae;
the method comprises the following specific steps:
s1.1: putting the worm-shaped insect larvae into water at 70 ℃ and boiling for 1-2 minutes;
s1.2: using a scalpel to cut a middle body segment on one side of the abdomen of the vermiform insect larva in a direction perpendicular to the direction of the larva body;
