Technical Field

The invention relates to the technical field of biology, in particular to a mosquito attractant.

Background

Mosquitoes belong to the family of the Insecta, Diptera. It is common to feed on the sap of plants, but female adult mosquitoes must breed offspring by biting vertebrates, feeding on blood to develop their ovaries. Female mosquitoes sucking blood can transmit dengue fever, malaria, yellow fever and other pathogens, so that outbreaks and epidemics of various infectious diseases are caused, and the health of human beings is seriously threatened.

For centuries, people have been searching for various methods to kill mosquitoes, the most important of which is chemical mosquito killing methods, such as the utilization of pyrethroid pesticides, DDT and the like, but the long-term use of the chemical compositions not only causes harm to human health and environmental pollution, but also causes mosquito resistance to the chemical compositions, thereby reducing the insecticidal efficiency. Some mosquito repellents, such as mosquito coil and mosquito repellent, can only temporarily repel mosquitoes but cannot reduce the quantity of the mosquitoes.

Mosquitoes are studied to find a blood-sucking host by factors such as light, temperature, smell, etc. According to the blood suction habit of mosquitoes, various types of mosquito trap devices are invented and manufactured, and the mosquitoes are trapped and killed, so that the purpose of reducing the number of the mosquitoes is achieved. Among them, in the mosquito trap device, a substance that attracts mosquitoes by emitting a special odor is called an attractant.

Disclosure of Invention

The invention aims to provide a mosquito attractant to solve the problems in the background technology.

In order to achieve the purpose, the invention provides the following technical scheme:

the mosquito attractant consists of the following raw materials in parts by weight:

s3: taking out 20% of alcohol according to the weight ratio, adding the alcohol into the mixed liquid A obtained in the step S1, mixing and stirring the mixture at the stirring speed of 50-100 r/min for 18-23 minutes to obtain mixed liquid C;

s4: taking out 5% of yeast fermentation product according to the weight ratio, filtering the yeast fermentation product, and filtering twice to obtain liquid A;

s5: taking out 0.5% of lactic acid according to the weight ratio, adding the lactic acid into S4 to obtain liquid A, mixing and stirring the mixture at a stirring speed of 120-150 r/min for 25-30 minutes to obtain mixed liquid D, and filtering the mixed liquid D to finally obtain mixed liquid E;

s6: taking out the mixed liquid B obtained in the step S2 and the mixed liquid E obtained in the step S5, heating and mixing the mixed liquid B and the mixed liquid E, controlling the heating temperature to be 26-28 ℃, controlling the stirring speed to be 50-100 r/min, stirring for 15-20 minutes, standing for six hours after stirring is finished, and controlling the temperature of a standing environment to be 26-28 ℃, so as to obtain a mixture F finally;

s7: and taking out the rest 30% of distilled water, the mixed liquid C obtained in the S3 and the mixture F obtained in the S6 according to the weight ratio, mixing and stirring the three at the stirring speed of 50-100 r/min for 40-60 minutes, and adding the rest 20.5% of distilled water in the stirring process, thereby finally obtaining the 100% attractant.

As a still further scheme of the invention: in the step S2, when sucrose is mixed with distilled water by heating, the ratio of sucrose to distilled water is 1: 3.

As a still further scheme of the invention: the standing in the step S6 is performed in an oxygen-free environment.

Compared with the prior art, the invention has the beneficial effects that:

the invention attracts mosquitoes through the taste emitted by the yeast fermentation product, thereby playing a role of attracting mosquitoes, the smell emitted by the attractant is heavily flavored with wine through alcohol, the alcohol can attract mosquitoes, the attraction force to mosquitoes is further improved, the smell of sweating of human body is simulated through lactic acid, the smell emitted by the attractant is flavored with the smell of sweating of human body, the attraction force to mosquitoes is further improved, the smell emitted by the attractant is flavored with sweet taste through sucrose, and the four ingredients are all perfume essences through the matching use of nonyl acetate, heptyl acetate, octyl acetate and ethyl butyrate, so that the attractant can simulate flower fragrance, the four ingredients are mixed together, the concentration of the fragrance is greatly improved, the fragrance and the sweet taste further contribute to promoting the attraction effect to mosquitoes, and the ingredient measures ensure that the smell emitted by the attractant is stronger, the luring effect is strong, direct amazing mosquito smell nerve, thereby apparent improvement lure mosquito efficiency, and lure the mosquito wide range, and is effectual, there is the important effect to the prevention and cure of mosquito, and be applicable to the entrapment of all kinds of mosquitoes, this lures the mosquito agent simultaneously and uses very simply, can directly use with the collocation of various types of mosquito trap device, can exert the effect of luring the mosquito, can effectually attract the mosquito in the trap device, it is good to lure the effect, when cane sugar and distilled water mix, carry out high temperature heating to it, can accelerate the rate of melting of cane sugar, increase the effect of mixing, simultaneously because the solubility of cane sugar increases along with the rising of temperature, great promotion the effect of melting of cane sugar and distilled water, make in the sweet taste of cane sugar is abundant dissolve the distilled water, be favorable to promoting the sugary mixed sweetness.
