Problems solved by technology

But recent reports think that lactic acid, which accounts for 20%-30% of skin metabolites, can act on Aedes aegypti alone. Other unidentified body odor components act synergistically, but when the lactic acid in the skin metabolites is broken down, the others no longer show any activity against Aedes aegypti

Embodiment 1

[0029] The invention provides a technical solution: a preparation method of a high-efficiency Aedes albopictus attractant, comprising the following steps:

[0030] Step 1: Put the raw materials including ammonium bicarbonate, n-hexanoic acid, 2-hydroxypropionic acid and 1-octen-3-ol into a four-hole glass reaction flask according to the mass ratio for mixing to obtain a mixture;

[0031] Step 2: Place the four-necked glass reaction flask on the heating device to heat the mixture;

[0032] Step 3: Use a thermometer to measure the temperature of the mixture on the heating device, so that the temperature of the mixture is controlled at 100°C;

[0033] Step 4: using a stirring device to stir the mixture for 8 hours;

[0034] Step 5: After the side reaction of the mixture, carbon dioxide and water are released and cooled completely;

[0035] Step 6: After cooling, the attractant 2-hydroxyammonium propionate product is obtained.

[0036] In step 1, the mass ratio of ammonium bica...

Abstract

The invention discloses a preparation method of a high-efficiency aedes albopictus attractant, which comprises the following steps: step 1: putting raw materials including ammonium bicarbonate, n-hexanoic acid, 2-hydroxy propionic acid and 1-octen-3-ol into a four-mouth glass reaction bottle according to a mass ratio to obtain a mixture; 2, placing the four-mouth glass reaction bottle on a heating device to heat the mixture; 3, using a thermometer for measuring the temperature of the mixture on the heating device, and controlling the temperature of the mixture to range from 100 DEG C to 110 DEG C; 4, stirring the mixture for 8-10 hours by using a stirring device; 5, after the mixture is subjected to side reaction, releasing carbon dioxide and water, conducting complete reaction, and then conducting cooling; and 6, conducting cooling to obtain an attractant ammonium 2-hydroxypropionate product. According to the invention, the ammonium 2-hydroxypropionate is used as an attractant for mosquitoes, and the mosquitoes are attracted by volatilized odor substances, so that a remarkable mosquito attracting effect is achieved, and an important role is played in preventing and controlling the mosquitoes.

Description

technical field [0001] The invention relates to the technical field of insect attractants, in particular to a preparation method of a high-efficiency Aedes albopictus attractant. Background technique [0002] Mosquitoes belong to the order Insecta, Diptera, and Culicidae, and there are about 2,700 species in the world. The mosquitoes that can transmit diseases in my country can be roughly divided into three categories: one is Anopheles, commonly known as Anopheles, which mainly transmits malaria; the other is called Culex, which mainly transmits filariasis and Japanese encephalitis; the third is It is called Aedes mosquito, with black and white stripes on the body, also known as Aedes mosquito, which mainly transmits epidemic type B and dengue fever. These mosquito-borne diseases kill more than one million people worldwide each year. In addition, mosquito bites also have a serious impact on human life, such as skin redness, swelling and itching after the bite, and the buzzi...
