Description

Mosquito attractant composition and preparation method and application thereof
Technical Field
The invention belongs to the technical field of daily insecticidal products, and particularly relates to a mosquito attractant composition, and a preparation method and application thereof.
Background
Mosquito (mosquito) belongs to the family of the diptera order, the class insecta, and is a tiny fly with piercing-sucking mouthparts. Common in the family of the mosquitoes are 3 genera of Anopheles (Anopheles), Culex (Culex) and Aedes (Aedes), the mosquitoes are full-metamorphosis insects, the life history is divided into 4 stages of eggs, larvae, pupae and adults, and the former 3 stages live in water. Female mosquitoes generally have to lay eggs after blood suction, lay eggs on water surfaces or wet surfaces close to water, and lay eggs several tens to hundreds at a time. For example, the anopheles sinensis lays eggs about 200 eggs each time, the eggs which are just laid are grey white but become black quickly, and the temperature (35 ℃) for hatching the aedes sinensis eggs needs 2-3 days in summer. The larvae, known as wigglers, live in water, breathe through the air holes, contact the water surface through the air holes, oil secreted around the air holes can prevent water from entering the air pipes, the larvae need to molt for 4 times, and then molt to form pupae, and the development time of the common mosquito larvae is about 7 days in summer. The pupae float under the water surface, extend out of the water surface through the breathing tube to be contacted with air, and are mostly still on the water surface except sinking to the bottom when being frightened, the pupae do not eat food, and the life is maintained by nutrient substances stored in a larval stage, wherein the pupal stage is generally 2-3 d. The time from egg development to mosquito formation depends on many factors such as temperature, food and environment, and under appropriate conditions, it takes about 9-15 days, and it can propagate 7-8 times a year.
Mosquito infests humans and livestock. Furthermore, mosquitoes are also vectors for malaria, viral encephalitis, dengue fever, filariasis, canine heartburn and west nile virus. The most widely applied prevention and treatment method at present is chemical prevention and treatment, which has quick response, economy and simplicity; at present, various mosquito repellent medicines are various, can be smeared on the skin, sprayed and burnt, and have the action mechanism of disturbing mosquito sensors so as to reduce the bite of mosquitoes. Some mosquito killing drugs sold in the market have certain toxic effect on human bodies although the effect is good, and if the mosquito killing drugs are not used properly and the residual toxicity of pesticides is difficult to remove in urban environment, the environment is easily polluted, and potential danger is formed on the safety and health of people. In addition, the chemical agent causes the extremely strong drug resistance of many mosquitoes, which becomes a prominent problem in the chemical control method.
Based on the above problems, some nonhazardous mosquito attractants have been studied to prevent and treat mosquitoes, but the existing published chemical attractant technology has the problems of weak pertinence to mosquitoes, limited attractant capability, complex preparation process and the like. Meanwhile, a plurality of physical mosquito trapping products such as an ultrasonic mosquito dispeller, a mosquito killer lamp and the like are available in the market, and the products have the advantages of environmental protection and sanitation, but also have the problems of single light trapping source, weak trapping force, low trapping efficiency and the like.

Application test example 1
The mosquito attractant compositions prepared in the examples 1 to 9 and the comparative examples 1 to 3 are subjected to the effect test of mosquito trapping, and firstly, one mosquito attractant composition with the area of about 20m is selected2The house of (1) was set to a height of about 3m, the temperature in the house was kept at about 25 ℃ and the humidity was kept at about 75%, 100 female mosquitoes and 100 male mosquitoes which did not take blood were selected, the mosquitoes were put into the house, the house was closed by turning on weak light in the house, and after trapping for 10 hours, the number of mosquitoes trapped was recorded, and the results are shown in table 1.
TABLE 1 statistical results of mosquito attraction
Figure BDA0003164289900000101
As can be seen from the results in table 1, the mosquito attractant compositions in the embodiments 1 to 9 have an attracting effect on mosquitoes that is significantly better than that of the comparative example, and the results show that the mosquito attractant compositions prepared in the embodiments have a better attracting effect on mosquitoes;
the difference between the comparative example 1 and the example 3 is that the component B contains no calcium oxide and is all charcoal, the quantity of the mosquitoes trapped by the comparative example 1 is greatly reduced, and the mosquito trapping effect of the example 3 is better, because the calcium oxide contained in the example 3 releases heat when meeting water, the composition has certain heat, because the mosquitoes are also extremely sensitive to the heat, and under the heat, the sweat components simulating human bodies, such as amino acid, some odor substances and lactic acid, are better, and the mosquito trapping effect is greatly enhanced;
the difference between the comparative example 2 and the example 3 is that the component B does not contain charcoal which is calcium oxide, the quantity of the mosquitoes trapped by the comparative example 2 is greatly reduced, while the mosquito trapping effect of the example 3 is better, because the charcoal is contained in the example 3, the charcoal is a porous black substance and can attract the mosquitoes by utilizing the black characteristic of the charcoal, in addition, the porosity of the charcoal enables carbon dioxide generated by fermentation to be gathered around the composition through the pore passages to enhance the attraction of the mosquitoes, and the pore passages of the charcoal are also convenient for the colonization of the activated yeast powder; the active yeast powder enables other components in the composition to slowly ferment to continuously generate carbon dioxide and flavor substances, so that the attraction effect on mosquitoes is enhanced;
comparative example 3 is different from example 3 in that component B is not contained, and the mosquito-attracting effect is extremely poor because comparative example 3 contains neither calcium oxide nor charcoal.
In conclusion, the mosquito attractant composition simulates the metabolism of a human body, fully considers the physiological habits of mosquitoes, and utilizes the synergistic relationship among the components to trap the mosquitoes.
Although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: those skilled in the art can still make modifications or changes to the technical solutions described in the foregoing embodiments or make equivalent substitutions of some technical features within the technical scope of the present disclosure; such modifications, changes or substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present invention, and should be covered by the protection scope of the present invention.
