Abstract

The invention discloses a plant-based mosquito repellent and its preparation method and application. Its active substances include: red pepper tree essential oil, dense flower rock wind essential oil and long sequence valerian essential oil; The content of the points is: 40-65 parts of red pepper tree essential oil, 20-35 parts of dense flower rock wind essential oil and 15-30 parts of long sequence valerian essential oil. The active components of the plant-based mosquito repellent of the present invention are mainly red pepper tree essential oil, dense flower rock wind essential oil and long sequence valerian essential oil, which are mainly extracted from plants. Insects develop resistance and are non-toxic to humans or livestock. The invention utilizes the synergistic effect of the three plant source essential oils to further improve the repelling effect and remarkably enhance the repelling effect on mosquitoes. The active component in the present invention is safe and non-toxic, and its preparation process is also non-polluting, so the repellent of the present invention is an environmentally friendly repellent.

Description

technical field [0001] The invention relates to a plant-based mosquito repellent and a preparation method and application thereof, belonging to the technical field of plant-derived pesticides. Background technique [0002] Mosquitoes are the vectors of various diseases, and can also cause local or systemic allergic reactions in the human body. For example, Aedes albopictus, a common mosquito species in Southeast Asia and China, is one of the most aggressive mosquito species in the world and an important virus vector, which can transmit many pathogens, including dengue fever, Ross River virus and Sydney Luo virus etc. Since Aedes albopictus mainly lives outdoors, using plant-derived mosquito repellents to prevent mosquito bites during outdoor activities is a safe, environmentally friendly, economical and practical way to block the spread of dengue virus. Large-scale mosquito eradication is more feasible. For a long time, people have used various methods to repel mosquitoes...
