And existing insecticide especially for books, archives insecticidal effect is not good, and also can cause harm to staff and surrounding environment in production and use process.

The object of the present invention is to provide a kind of insecticidal, repelling, anti-mildew as a whole, easy to prepare, convenient to use, safe for human body, non-polluting environment, and has no adverse effects on books, archive paper, film, film and other materials. A new biopesticide for sanitation. At the same time, a preparation method of the insecticide is provided.

In order to realize the purpose of the present invention, the present invention provides following technical scheme:

The mildew-proof and repellent insecticide is a medicament made of the following raw materials in percentage by weight:

Pyrethrins 10% Eucalyptus Oil 3% Turpentine 5% Menthol 2%

Natural camphor 10% Chinese herbal powder 10% Diatomaceous earth 20% Paraffin 30%

Pepper 10%

Among the above-mentioned anti-mildew repellent insecticides, Chinese herbal medicine powders are preferably Atractylodes atractylodis, Ligusticum edulis, and Rhizoma Chuanxiong.

The present invention provides the method for preparing above-mentioned insecticide simultaneously:

A. Take Atractylodes atractylodis, Ligusticum edulis, Ligusticum chuanxiong, crush them in a weight ratio of 1:1:1, and mix them for later use;

B, get pyrethrin, eucalyptus oil, turpentine and mix well, add menthol and camphor, add 5% sustained-release agent and fully shake, finally add the Chinese herbal medicine prepared in step A and mix well;

C. Take the paraffin and melt it in a water bath, add the remaining diatomaceous earth, stir well, and let it cool down to 35-60°C;

D. Mix the two parts B and C evenly, pour it into the mold while it is hot and let it cool and solidify.

The medicament of the present invention is a natural compound insecticide, which is mainly processed, refined and rationally prepared from various plants with functions of killing insects, repelling mildew and preventing mildew. The insecticidal active components are pyrethroids and some volatile terpenoids, which have contact and repellent effects, and the anti-mold repellent active components are aromatic monoterpenes and sesquiterpenoids, which have strong repellent and different degrees of anti-mildew effect.

Specifically, the main functions and effects of each component in the prescription are:

Natural pyrethrin (contains six compounds): insecticidal, moth-proof, and repellent.

Plant essential oil: eucalyptus oil - repellent, insecticidal, anti-mildew. Turpentine - anti-moth, repellent.

Natural menthol: repels, kills insects, inhibits bacteria, clears the mind, and purifies the air.

Aromatic Chinese herbal medicine fine powder: insecticide, repellent, anti-mildew, fresh air.

Diatomaceous earth: slow release agent for the active ingredient.

Paraffin: coagulant.

The contact killing effect of pyrethroids is mainly through the adsorption of fat and protein in the epidermis of insects, which hinders the action of multifunctional oxidases of insects and produces a knockdown phenomenon. It invades the blood from the insect body wall or trachea and stimulates the insect body. The nervous system of each tissue cell and its surrounding nerve fibers quickly paralyze the worm body and are poisoned, and finally die. Benezet, H.J. et al., in 1986, evaluated the toxicity test of 11 insecticides on tobacco beetle Lasioderma serricome raised on cornmeal-yeast or tobacco by spot treatment. It showed that the killing effect of pyrethrin on tobacco beetle was better than that of nicotine and dichlorvos. , trichlorfon and other strong.

The contact killing effect of some volatile terpenoids mainly enters the insect body through the respiratory system, and after being absorbed by the tissue, it stimulates the central nervous system to overexcite the insect body, causing panic, convulsions, and convulsions, such as turpentine oil, eucalyptus oil, and peppercorns. wait.

The anti-mildew and repellent active components are plant essential oils and aromatic Chinese herbal medicines. Most of them are monoterpenes and sesquiterpenes, such as menthol, eucalyptol, β-pinene, atractylodes, ligusticum, etc., which have a strong repellent effect. Krishnarajah, S.R., etc., in 1985, the avoidance and toxicity test results of certain vegetable oils and their terpene components to Sitotrgacerealella, the main pest of stored rice, showed that β-pinene is the most effective repellent. Plant essential oils: Eucalyptus oil, turpentine oil, and aromatic Chinese herbal medicines all have different degrees of antibacterial and anti-mold effects, especially the geraniol component contained in the fine powder of Chinese herbal medicines has a strong anti-mold and killing effect on mold.

The beneficial effects of the present invention will be further described below in conjunction with the embodiments of the present invention, but the content of the present invention is not limited thereto.
