Technical Field
The invention relates to the field of odor removal and mosquito repelling, in particular to a mosquito repelling liquid based on plant essential oil, which is applied to mosquito repelling and sterilization, tranquilization and calming, air purification and the like.
Background
In tropical or subtropical areas, mosquitoes are inundated, and not only blood sucking interferes with the normal daily life and rest of human beings, but also diseases can be transmitted. Mosquitoes are one of the main vectors, can transmit infectious diseases such as malaria, yellow fever, dengue fever and the like, and seriously threatens human health. Mosquito repellent mainly used in the market at present is chemically synthesized DEET (DEET), although the DEET has a certain effect on repelling mosquitoes, along with the long-term abuse of chemical insecticides, the drug resistance of mosquitoes becomes stronger and stronger, and the DEET has certain side effect on human bodies, so that the people worry about the mosquito repellent. Therefore, it is an urgent matter to find plant type repellent which has high efficiency, low toxicity, easy degradation and no harm to human body.
In recent years, researchers at home and abroad have been devoted to substituting natural ingredient insecticidal and repellent substances for insecticides. At present, a plurality of plant essential oils have been found to have certain poisoning and repelling effects on mosquitoes, and the repelling mechanism is that the mosquitoes selectively avoid a signal source containing the plant essential oils or are repelled by the plant essential oils to reduce the invasion to human beings, so that people are prevented from being disturbed by the mosquitoes, and the spread of insect-borne diseases is reduced. The natural plant essential oils have an avoiding effect on mosquitoes, can inhibit the growth and development of the mosquitoes and even play a role in killing the mosquitoes, larvae and ova thereof, have the advantages of mild property, safety and the like, and have various development and application potentials. Chinese plant resources are rich, and wide resources and convenient conditions are provided for finding efficient botanical repellent.
