Description
Technical field
The invention belongs to mosquito repellent product technical field more particularly to a kind of culicifuges and its preparation from plant extracts
Method, the in particular to culicifuge of the extract containing weasel hemp nettle.
Background technique
At present in the world there are about more than 3500 kinds of mosquitoes and its subspecies, the most common mosquito has Aedes, Culex and anopheles
Belong to, mosquito sucks the blood of people and various animals, harasses the mankind and propagates malaria, filariasis, Japanese Type-B encephalitis, west with this
A variety of diseases such as Nile virus disease, dengue fever, wherein it has been reported that carapuru virus type up to more than 40 kinds.
For a long time, people control mosquito using various methods, and main means are using chemical insecticide and chemical repellent
Agent, such as Metadelphene (DEET), mosquitofugal oil (DMP), citronellal, organic phosphorus, carbamates, expelling parasite amine, these medicaments
Effect is good, efficiency time is long, but mosquito is easy to produce resistance, and is used for a long time and will cause serious environmental pollution and to human body
Generate toxic side effect.
It has a long history with natural plants mosquito repellent, mainly there is plant of directly smearing and burn to carry out two kinds of sides of fumigation
Formula.Ancient Egyptian, which smears, has the tobacco tar of overpowering odor to prevent bite by mosquitos;Ancient times, Russia herdsman smeared eucalyptus leaf juice
On the skin and burning moss and pine tree leaf carry out expelling mosquito;Ancient Times in China resident is to burn plant as main expelling mosquito side
Method, common plant have dry palpus of wormwood herb, sesame slices, Jing Ye and various pericarps, corn etc..However, using plant sootiness
Method, this method are limited by raw material, and easily cause fire, and the smog generated there are hidden danger, especially sootiness is tight
Ghost image rings room air.
In recent years, plant source culicifuge with its safety, wide spectrum, it is degradable and the advantages that be not easy to produce resistance by people
Attention, be mainly derived from the extract or volatile oil at the different tissues position of each plant, such as: wild chrysanthemum, geranium oil, gold and silver
Caul-fat, Artemisia oil, catnip oil, the grey oil in mountain, retinal, wintergreen, lemongrass oil, eucalyptus citriodora oil, citronella oil, lavender oil, fourth
Sesame oil etc., but these are very short with plant volatile oil mosquito-repellent action time as main component, generally at 1~2 hour,
Repelling effect is bad.
Although having put into the various resources such as a large amount of human and material resources in the research and development of plant source culicifuge, economically may be used
The research of culicifuge capable, based on plant extracts, especially research and development safety and environmental protection, mild, irritation is small, smell is pure and fresh and
The plant source culicifuge of high-efficient and lasting is still long-term unsatisfied demand.
Summary of the invention
The purpose of the invention is to overcome the deficiencies of the prior art and provide a kind of culicifuge from plant extracts and
