Preparation method of dry specimen of coleopteran insects

Abstract

According to the invention, drying agent, a mildew preventive and the like are mostly adopted for preparation and preservation of a dry coleopteran insect specimen in a dry environment, the requirement for the environment is strict, a temperature and humidity control device needs to be matched, once the specimen is exposed in air for a long time, the specimen is prone to being affected with damp and damaged due to moisture absorption and the like, protectiveness is low, and the specimen protection cost is high. The invention provides a novel preparation method of a dry specimen, which comprises the following steps of: softening, needle inserting, drying, permeating and film forming, so that a film-forming material permeates and treats a substrate of the dry specimen, the appearance characteristics and the form of the specimen are not changed, a non-polar protective layer is formed in a capillary structure of the dry specimen, the moisture resistance of the specimen is improved, and therefore, the service life of the dried specimen is prolonged.

Description

technical field [0001] The invention relates to a method for making dried specimens of Coleoptera insects. Background technique [0002] Existing dry specimens are mostly preserved by qualitative drying, and are stored in a dry environment with desiccant and anti-fungal agents. The environmental requirements are strict, and temperature and humidity control equipment is required. Once exposed to the air for a long time, often due to absorption It is easily damaged by moisture due to moisture and other reasons, and has low protection. In particular, specimens of rare and protected species are often affected by improper preservation, affecting their scientific value and resulting in the loss of species. There are also preservation methods such as immersion and film coating for supplementation, but the above methods all have defects such as inconvenient to carry, limitations on the physical volume of the specimen, and inability to directly touch for detailed observation.

[0002] Existing dry specimens are mostly preserved by qualitative drying, and are stored in a dry environment with desiccant and anti-fungal agents. The environmental requirements are strict, and temperature and humidity control equipment is required. Once exposed to the air for a long time, often due to absorption It is easily damaged by moisture due to moisture and other reasons, and has low protection

In particular, specimens of rare and protected species are often affected by improper preservation, affecting scientific value and resulting in the loss of species

There are also preservation methods such as immersion and film coating for supplementation, but all of the above methods have defects such as inconvenient to carry, limited to the physical volume of the specimen, and cannot be directly touched for detailed observation.

Later, the epoxy resin method for insect specimens appeared in Guangdong and other places, which solved the problem of biological specimen preservation. However, there are still some shortcomings in this method. For example, after the specimen is completed, it needs to be polished. Moreover, the production process is prone to air bubbles and specimen discoloration caused by temperature rise, which limits the further promotion of this technology
