Problems solved by technology

However, the individuals of skin beetles and silverfish are very small, not easy to find but easy to carry, and they are very resistant to stress. If skin beetles and silverfish are accidentally brought into the specimen box, the specimens will be corroded and scientific research will be lost. and preserve the value
[0003] At present, in the preservation of insect specimens, natural or synthetic camphor products (such as camphor balls and camphor tablets) are mostly used as anti-moth agents, but this type of anti-moth agents has the following defects: the action time is not long, and it needs to be replenished within half a year at most ; Synthetic camphor products contain dichlorobenzene and naphthalene, which will damage human health; the anti-moth effect on specimens is very limited
On this basis, in the Chinese patent application "a kind of anti-moth method for insect adult specimens" (application number 200410021267.4), camphor tablets are combined with commercially available insecticides to carry out anti-moth treatment for insect specimens. Infested by moths for up to 24 months, but this method also requires the use of camphor products and insecticides, which is likely to cause adverse effects on humans and the environment

preparation example Construction

[0045] The preparation method includes the steps of preparing shell powder, preparing micro-powder of Polygonum chili, preparing step of wormwood powder, and mixing.

[0046] The preparation steps of the above-mentioned shell powder include:

[0047] S1: First, wash the shells with clean water to remove surface stains, and then use concentrated hydrochloric acid for desalination and degreasing to obtain the shells after desalination and degreasing.

[0048] The above-mentioned desalination and degreasing treatment includes: soaking the shells with 0.3%-1% hydrochloric acid solution or 0.5%-1% sodium hydroxide solution for 30-60min, for example: 30min, 35min, 40min, 50min, 60min, preferably 45min.

[0049] S2: The above-mentioned desalinated and degreasing shells are then subjected to drying treatment to obtain dried shells.

[0050] The temperature of the above drying treatment is 40-60° C. to reduce the water content of the shells to less than 5%, thereby obtaining dried she...

Embodiment 1

[0063] The raw materials of the moth inhibitor of the present embodiment, in parts by weight, include:

[0064] Shell powder (using mussel shell, particle size is 800-1000μm) 40 parts by weight,

[0065] Polygonum chili powder (particle size is 100-200nm) 20 parts by weight,

[0066] Wormwood micropowder (particle size is 100-200nm) 20 parts by weight.

[0067] The moth repellant is prepared as follows:

[0068] 1. Preparation of shell powder:

[0069] S1: First, the shells are washed with clean water to remove surface stains, and then soaked in a hydrochloric acid solution with a concentration of 0.5% for 45 minutes for desalination and degreasing treatment to obtain the shells after desalination and degreasing.

[0070] S2: drying the demineralized and degreasing shells at 40-60° C. until the water content is less than 5% to obtain dried shells.

[0071] S3: The dried shells are then pulverized by an air sieving pulverizer to obtain the above-mentioned shell powder.

Abstract

The invention belongs to the technical field of insect specimen preservation, and in particular relates to a mothproof agent for insect specimens and a preparation method thereof. The anti-moth agent includes the following raw materials in parts by weight: 10-40 parts by weight of shell powder with a particle size of 500-2000 μm, 10-20 parts by weight of Polygonum micropowder with a particle size of 50-1000 nm, and a particle size of 50 10-20 parts by weight of wormwood fine powder of 1000nm. The invention uses the above three raw materials to compound to obtain the anti-moth agent, and each raw material synergizes and benefits each other, and has good anti-moth performance and long service life.

Description

technical field [0001] The invention belongs to the technical field of insect specimen preservation, and in particular relates to a moth inhibitor for insect specimens and a preparation method thereof. Background technique [0002] Insect specimens, especially insect specimens, are the basic materials for insect classification research. Traditional insect classification relies entirely on observing their morphological structures. Therefore, the key point of specimens for scientific research is to preserve the integrity of insect morphological characteristics. Therefore, the moth-proof work for insect specimens is particularly important. The requirements for the maintenance of insect specimens in museums are even higher. The main "natural enemies" of insect specimens, especially insect specimens, include beetles and silverfish (also known as beetles and beetles), both of which feed on insect carcasses for a living. Therefore, the most important thing to preserve specimens is...
