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

[0037] Embodiment 1, preparation and detection of attractant

[0038] 1. Prepare 20% lactic acid powder

[0039] According to the mass ratio, add 1 gram of lactic acid (Sinopharm Chemical Reagent Co., Ltd., 30108518) into 4 grams of β-cyclodextrin (Sigma, C0147), stir well, and store it in a small sealed box (it must be sealed before storage). OK, to prevent early loss of flavor. Seal without dark.).

[0040] 2. Prepare 15% ammonia gel

[0041] First mix 0.25 g of S-305 (an emulsifier, Guangzhou Huaqing Fine Chemical Co., Ltd.) and 0.25 g of white oil (Foshan Aster Chemical Technology Co., Ltd., cosmetic grade -70#), and then mix 3 g of 25 % ammonia water (Merck, M10543201) was added to 1 gram of deionized water and mixed, under stirring, the mixture of S-305 and white oil was added to the ammonia water mixture solution, stirring continuously until a white paste, and then 0.5 gram of β- Cyclodextrin (the final concentration of ammonia in the gel after mixing is 15%), after ...

Embodiment 2

[0050] Embodiment 2, preparation and detection of attractant

[0051] 1. Prepare 15% lactic acid powder

[0052] According to the mass ratio, 0.75 g of lactic acid is added to 4.25 g of β-cyclodextrin, fully stirred evenly, and then packed into a small airtight box.

[0053] 2. Prepare 15% ammonia gel

[0054] First mix 0.25 g of S-305 and 0.25 g of white oil evenly, then add 3 g of 25% ammonia water to 1 g of water and mix evenly. Under stirring, add the mixture of S-305 and white oil to the ammonia water mixed solution, and keep stirring Stir to a white paste, then add 0.5 g of β-cyclodextrin (after mixing, the final concentration of ammonia in the gel is 15%), stir until it solidifies, and put it into a small sealed box (S-305, white oil , the quality of ammonia and β-cyclodextrin in ammonia water is 0.25:0.25:0.75:0.5).

Abstract

The invention discloses an aedes albopictus attractant and a preparation method thereof. The invention provides an attractant, and the active ingredients include lactic acid and ammonia at a weight ratio of (15-20):(5-15). The weight ratio of lactic acid to ammonia is 20:15 or 15:15 or 15:10 or 10:15 or 20:15 or 20:10. The attractant consists of powder containing the lactic acid and gel containing the ammonia water. Experiment indicates that: the attractant characterized in the inducing activity against aedes albopictus provided by the invention can be applied to the population monitoring and trap-kill prevention and treatment of aedes albopictus.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to an attractant for Aedes albopictus and a preparation method thereof. Background technique [0002] Aedes albopictus, commonly known as "Asian tiger mosquito", is addicted to human blood and sucks blood fiercely. It is widely distributed in most areas north of Liaoning in my country. It is the main vector of dengue fever and dengue hemorrhagic fever in my country, and it is also the main tool for urban mosquito control. One of the mosquito species. [0003] Previous studies have found that female mosquitoes respond behaviorally to human sweat, which is made up of water, lactic acid, ammonia and urea. Early reports believed that lactic acid was only available in CO 2 active when present. 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 acted synergistically, but when the...
