Problems solved by technology

However, this tablet-type attractant can only have a lure effect when used in conjunction with the mosquito-killing magnets of the American Biophysics Corporation. When used together with the mosquito trap lamps commonly used in my country, the lure effect is not ideal

Embodiment 1

[0021] Embodiment 1, preparation and detection of attractant

[0022] 1. Preparation of attractant

[0023] Prepare 5% 1-octen-3-ol powder (total weight 10 grams): according to the mass ratio, 0.5 gram of 1-octen-3-ol (Jinan Luli Chemical Co., Ltd., 3391-86-4) Add 9.5 g of β-cyclodextrin (Sigma, C0147), stir thoroughly, and put it into a small sealed box to obtain attractant 1.

[0024] Prepare 6.3% 1-octen-3-ol powder (total weight 10 grams): according to the mass ratio, add 0.63 grams of 1-octen-3-ol to 9.37 grams of β-cyclodextrin, and stir well , into a small sealed box to obtain attractant 2.

[0025] Prepare 10% 1-octen-3-ol powder (total weight 10 grams): according to the mass ratio, add 1 gram of 1-octen-3-ol to 9 grams of β-cyclodextrin, and stir well , into a small sealed box to obtain attractant 3.

[0026] Prepare 15% 1-octen-3-ol powder (total weight 10 grams): according to the mass ratio, add 1.5 grams of 1-octen-3-ol to 8.5 grams of β-cyclodextrin, and stir ...

Embodiment 2

[0036] Embodiment 2, preparation and detection of attractant

[0037] 1. Preparation of attractant

[0038] Preparation of attractant 4: Add 1.5 g of 1-octen-3-ol into 8.5 g of β-cyclodextrin according to the mass ratio, stir well, put it into a sealed small box, and obtain attractant 4.

[0039] 2. Application of attractant

[0040] In the rice field area with a high density of Culex tritaeniorhynchus (stinging index of 30 / half an hour or more), 6 U-shaped mosquito traps were placed, and CO 2 Flow rate is adjusted to 200ml / L, wherein 3 use 15% 1-octen-3-alcohol powder (attractant 4, experimental group 1-3), 3 do not use (control group 1-3), the interval between mosquito traps 55 meters, turn on the mosquito trap at 6:00 p.m., retract it at 8:00 a.m. the next day, and count the captured mosquitoes after identification. The experiment was repeated for three days, and the results were averaged.

[0041] The method of using the attractant: the sealed small box containing 15% ...

Abstract

The invention discloses mosquito attractant and a preparation method thereof. The mosquito attractant consists of 1-octene-3-alcohol and beta-cyclodextrin; and the weight ratio of the 1-octene-3-alcohol to the beta-cyclodextrin is: (0.5 to 2.5):(7.5 to 24.69). The weight ratio of the 1-octene-3-alcohol to the beta-cyclodextrin is: (0.5:9.5), (0.63:9.37), (1:9), (1.5:8.5), (2:8), (2.5:7.5) or (1.66:24.69). Approved by experiment, the mosquito attractant has attractive activities for culex tritaeniorhynchus and anopheles sinensis, mosquitoes can be attracted by smell substances which are volatilized by the attractant, and the mosquito attractant can be used for the species group monitoring and attraction and prevention of the culex tritaeniorhynchus and the anopheles sinensis.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to a mosquito attractant and a preparation method thereof. Background technique [0002] Culex tritaeniorhynchus and Anopheles sinensis are rice field-type mosquitoes widely distributed in most provinces of my country, among which Culex tritaeniorhynchus is the main vector of epidemic encephalitis Japanese in my country, and Anopheles sinensis is the main vector of malaria in my country medium. For many years, the population density monitoring method of Culex tritaeniorhynchus and Anopheles sinensis has been using lamp-baited mosquito traps such as Kung Fu Xiaoshuai. Because lamp-baited mosquito traps only use black light lamps to lure mosquitoes, the Culex tritaeniorhynchus and Anopheles sinensis have poor attracting effects, and it is often difficult to reflect the actual local mosquito population density. [0003] Octenol (mushroom alcohol) is a mosquito-attracting substance separat...
