Abstract

The invention discloses a plant essential oil-containing mosquito repellent. The main components are nepeta oil, citronella oil and the like. The repellent has the characteristics that: DEET and other chemical repellents are not contained, plant essential oil is taken as the main components, the repellent can be made into oil-based type, alcohol-based type, and water-based repellents, has a low cost and no toxicity, and has good repellent effects on Aedes albopictus.

Description

technical field [0001] The invention relates to a mosquito repellent, in particular to a mosquito repellent containing plant essential oil, which has a good repelling effect on Aedes albopictus. Background technique [0002] Mosquitoes are one of the important vectors, carrying a variety of pathogenic microorganisms in their bodies, which seriously endanger human health. Repellants are one of the means by which humans control mosquitoes. At present, most of the commonly used repellants are artificially synthesized, among which DEET is currently recognized as the best broad-spectrum mosquito repellent in practical application (Xue Feiqun, 1992), relying on natural volatilization or with the help of carriers The volatilized odor makes mosquitoes avoid and get close to the human body after smelling it, so as to prevent biting and invasion and protect human health (Gao Jing and Gao Shen, 2002). However, recent studies have shown that DEET has toxic side effects, such as causin...
