Problems solved by technology

At present, chemically synthesized insecticides such as pyrethroids are the main insecticides for flies, but the resistance of flies to these insecticides shows a significant upward trend, and pyrethroid insecticides have certain acute toxicity , can cause symptoms such as dyspnea, cough, bronchospasm, nausea and vomiting, headache, etc., and more studies have shown that pyrethroid insecticides are neurotoxic substances, and exposure of humans, especially newborns, to this insecticide may cause developmental neurosis. Toxicity, Reproductive Toxicity, and Immune System Toxicity
In order to solve the hazards of chemically synthesized insecticides, researchers have developed plant-derived fly repellents and insecticides. Compared with chemically synthesized insecticides, repellents and insecticides prepared from plant extracts Repellants have a certain repellent effect on flies, and have the characteristics of safety, low toxicity or non-toxicity, and are not easy to cause resistance to houseflies. However, there are few types of repellents and insecticides from plant sources at present, and the plant source , and some plant-derived repellents are not effective

Embodiment 1

[0022] 1) Preparation of active composition

[0023] The fruit of Hunan Mujiangzi is co-distilled to obtain the essential oil of Mujiangzi; the whole herb of Julienne is co-distilled to obtain the essential oil;

[0024] The active composition is obtained by mixing the essential oil of calyx japonica, the essential oil of wild berries, the essential oil of osmanthus osmanthus and absolute ethanol according to the mass ratio of 50:25:20:5, and after mixing evenly.

[0025] 2) Preparation of fly repellent

[0026] According to mass percentage, active composition 75%, emulsifier (propylene glycol fatty acid ester) 4%, antioxidant (2,4-dimethyl-6-tert-butylphenol) 0.3%, preservative (sorbic acid) Mix 0.4%, humectant (hyaluronic acid) 4%, and pH regulator (citric acid) 0.3% evenly, then pump into the emulsification pot for emulsification, after emulsification, after homogenization for 5 minutes, the fly repellent is obtained; Finally, samples are taken to test the stability and a...

Abstract

The invention discloses a fly repellent agent, and a preparation method and applications thereof. A main active component of the fly repellent agent is a composition containing, by mass, 40 to 65 parts of Litsea hunanensis essential oil, 20 to 35 parts of Elsholtzia rugulosa essential oil, and 15 to 30 parts of Cinnamomum pauciflorum essential oil. According to the preparation method, a pluralityof plant-sourced safe nontoxic essential oil are taken as the main active ingredients of the fly repellent agent, so that the fly repellent agent is safe, and is nontoxic; drug resistance is not easily caused; the effect is better than that of single component essential oil. The synergistic interaction effect of Litsea hunanensis essential oil, Elsholtzia rugulosa essential oil, and Cinnamomum pauciflorum essential oil is achieved, so that the repellant effect on fly is better. The preparation method is simple; the main raw materials are plant-sourced materials; and no environment pollution iscaused.

Description

technical field [0001] The invention belongs to the technical field of botanical pesticides, and in particular relates to a fly repellant and its preparation method and application. Background technique [0002] Flies are relatively common insects in our lives. Because of the numerous bristles and hairs on their bodies, they can mechanically carry and transmit various pathogens, which are very harmful to our lives. In addition to harassing people and contaminating food, the harm of flies is more to spread various diseases and cause myiasis. Fly-borne diseases include mechanical transmission and biological transmission. Mechanically transmitted diseases are mainly caused by flies spreading pathogens through activities such as landing, licking, vomiting and excretion. The transmitted diseases mainly include digestive tract diseases ( Such as dysentery, cholera, etc.), respiratory diseases (such as tuberculosis, pneumonia) and skin diseases; biologically transmitted diseases m...
