Technical Field

The invention belongs to the technical field of preparation of mosquito repellents, and particularly relates to a plant mosquito repellent liquid composition, a mosquito repellent liquid and a preparation method of the plant mosquito repellent liquid composition.

Background

The mosquitoes come with the coming of summer every year. The biting of mosquitoes not only causes itching and swelling, but also has more serious problems that different germs carried by the mosquitoes spread various mosquito-borne diseases and harm human health, such as malaria, yellow fever, dengue fever, western equine encephalitis, Japanese encephalitis, West Nile virus disease and the like.

At present, the main means for preventing and killing mosquitoes is to use an insecticide and a repellent. The pesticide is mainly a chemical synthetic pesticide. The chemical insecticide is used to kill mosquito and insect and is an important measure for controlling the diseases transmitted by the chemical insecticide, and in the chemical prevention and control for decades, because the insecticide is used and abused in a large amount and the medication method is not very reasonable, the mosquito and insect can generate resistance to various insecticides, and the resistance degree is gradually increased. With the increasing degree of mosquito resistance, the amount of insecticide used has to be increased, which results in not only increased costs but also severe environmental pollution, limiting the further use of chemical insecticides. The development speed of mosquito resistance is reduced while mosquitoes are prevented and treated, and people pay more and more attention.

As people become increasingly concerned about health and the ecological environment, more people select repellents. The repellent does not directly act on insects to kill the insects, and chemical actions (such as color, smell and the like) of the repellent cause the insects to be prohibited, so that the effect of preventing mosquito bites is achieved. The current repellents on the market are natural mosquito repellents and artificially synthesized chemical mosquito repellents, and the chemical repellents account for most shares of the market, but the toxicity and safety of the chemical repellents are always the key points of concern for all people. For example, currently, the commonly used diethyltoluamide can inhibit the acetylcholinesterase activity of the central nervous system of mammals, can induce nervous system symptoms after long-term or large-scale use, and has various problems of corrosivity to plastics and leather, human discomfort caused by odor and the like.

In addition, chemical insecticides and evasion agents cause rapid resistance rise during use, and long decomposition time, which causes serious residue problems, which draws high attention from people, and re-evaluates the use of chemosynthetic pesticides, so that the use of chemosynthetic pesticides is seriously challenged. With the improvement of living standard, people pay more and more attention to health, and in addition, China is undergoing industrial transformation, the requirement on environmental protection reaches unprecedented height, the pesticide industry has to face the influence on environmental pollution while developing, and the requirement on using environment-friendly products is paid extremely high attention. The plant with insect killing and expelling activity has the functions of mainly using the secondary metabolites of the plant, and the plant utilizes the secondary metabolites produced by the plant to defend the attack of plant diseases and insect pests in the process of long-term co-evolution with mosquitoes. The medicinal vegetable oil as a naturally occurring substance has a smooth degradation way in nature, is not easy to remain and has small toxicity accumulation problem. The natural mosquito repellent has the advantages of low toxicity and environmental protection in sanitary vector insect control, so that people throw eyelight to the botanical insecticide and repellent, and the natural mosquito repellent with the advantages of fresh smell, low toxicity or no toxicity, no burning sensation on skin and the like is favored by people. However, most of the existing repellents only contain a single natural plant extract, so that on one hand, the repellent effect is very limited, on the other hand, the odor is monotonous, and after the repellent is used for a long time, a human body is easy to feel tired. Therefore, how to further develop a plant-derived repellent which is nontoxic, harmless, excellent in mosquito repellent effect, unique in fragrance and enjoyable is a problem to be solved at present.
