Embodiment 1

[0022] In the laboratory, octanoic acid 10 μg / mL and indole 0.1 μL / mL were mixed at a volume ratio of 1:1 as an attractant. The "T" type olfactometer (refer to the design of Geier et al., 1996 with some modifications) was used to measure the attractant's attractant effect on female adults of Culex pachypis. The base arm of the "T" type olfactometer is 35cm long, and the two "T" arms are each 20cm long and 7cm in diameter. Connect the base arm to the mosquito release chamber; two sample chambers are extended from the ends of the two "T" arms, and the airflow is connected to the sample chamber through the "Y" pipe. Before the air flow enters the sample chamber, the air is first filtered by activated carbon and humidified with distilled water, and the gas flow in the olfactometer is adjusted to 900ml / min. The room temperature is 26-28°C, the relative humidity is 70-80%, and the light intensity in the olfactometer is 100-150 lux. Use a mosquito suction tube to suck 30 female mos...

Embodiment 2

[0026] In the laboratory, octanoic acid 10 μg / mL and indole 0.1 μL / mL were mixed at a volume ratio of 1:1 as an attractant. The "T" type olfactometer was used to measure the attracting effect of compounds on female adults of Aedes albopictus. The test method is the same as above.

[0027] Results: The arm end of the attractant can attract about 88% of mosquitoes. The female Aedes albopictus mosquitoes reacted towards the attractant, and the attractant had obvious attracting effect on the female Aedes albopictus mosquitoes.

Embodiment 3

[0029] Field release test. This experiment was carried out around the human house in Xiaokeyi Village, Xundian County, Kunming City in August 2009. The mosquito trap MT-1 (GB / T5836.2) jointly manufactured by the Institute of Microbial Epidemiology of the Chinese Academy of Military Medical Sciences and Beijing Longguan Technology Development Co., Ltd. is used. CO 2 The air flow through the fan blows the mosquitoes into the bag. Caprylic acid and indole were mixed with ethanol to a concentration of 10 μg / mL and 1 μL / mL, mixed at a volume ratio of 1:1, put into a glass bottle, and hung beside a mosquito trap. Trap from 5:00pm to 10:00pm. Attractant+CO 2 Mosquito traps and CO 2 The mosquito trap lamps were compared at the same time, and the test was carried out for 3 days, and the mosquito trap results of the 3 days were averaged. The results are as follows:

Abstract

The invention relates to culex and aedes attractant and an application method, belonging to the mosquito attractants containing organic compounds; the attractant in the invention is formed by mixing caprylic acid and benzpyrole, wherein the concentration of the caprylic acid is 10mug / ml, and the concentration of the benzpyrole is 0.1-1mug / ml, and the caprylic acid and the benzpyrole are prepared by 1:1 of volume ratio; the application method is that: the attractant is arranged in the room or at the field and is released slowly and naturally; in the field, the attractant is arranged in a glass long-neck volumetric flask or is released by being arranged in glass long-neck bottles with corks or is used with an insect trap. In the invention, the attractant can effectively attract culex pipiens pallens, aedes albopictus and other mosquitos, and the drug diffusion is little, and the attraction efficiency is high.

Description

technical field [0001] The invention belongs to a mosquito attractant containing an organic compound. Background technique [0002] Mosquitoes include Culex light-coloured, Culex bitaeniorhynchus, Culex fatigue, Culex mimic, Culex browntail, Culex stylus, Culex brownhead, Culex malayi, and Aedes albopictus, among which Culex albopictus Aedes mosquitoes and Culex palustris are widely distributed in my country and are more harmful. Protecting humans from mosquito bites is an important means of preventing and controlling mosquito-borne infectious diseases, especially for some mosquito-borne infections that currently have no vaccines or specific drugs. Disease, repelling and luring to eliminate mosquitoes become the most feasible method. Mosquito attractants have developed rapidly abroad recently, and there are commercial mosquito attractants such as octonol, but there is no commercial mosquito attractant in China. Some scientific research departments have begun to screen attract...
