Pest and disease specimens, as an important part of crop research, are the basic materials for research and course teaching such as animal and plant quarantine and pest control. Agricultural pests are usually divided into two categories based on their movement posture: reptiles and flying insects. In the process of making specimens of flying pests, their wings are usually made to be open.

[0003] In the patent application entitled "An Agricultural Pest and Disease Specimen Preservation Device" with the publication number CN207870181 U in China, it is disclosed that by using a micro vacuum pump in conjunction with a nano filter, the air retained in the preservation device can be easily extracted, thereby ensuring the internal vacuum effect of the preservation device and increasing the sample preservation period. By using a box cover in conjunction with a rubber connecting protrusion and a card slot in the inner cavity of the top end face of the sample placement slot, the sample placement slot is sealed, and then the magnet A surface provided on the preservation box body is combined with the magnet B surface of the side wall of the box cover, which is conducive to increasing the connection strength between the box cover and the box body, thereby ensuring the sealing effect of the preservation device. However, the specimen preservation device still has shortcomings during use. When preserving pests with wings, since the wings of the pests are in an open state, when moving the preservation device and transporting pest and disease specimens, the preservation device is subjected to external force and vibration, which can easily cause damage to the wings of the pests, which is not conducive to protecting the pest and disease specimens.
