Problems solved by technology

At present, the control of flies is basically based on chemical control, but the chemical control of flies has the following problems: (1) Since flies mostly live in human-inhabited areas and the surrounding environment, there are many overlaps with human activity areas, Food pollution and human poisoning incidents caused in the prevention and control process occurred frequently; (2) In the chemical control process, a large amount of pesticides will be released into the external environment, causing environmental pollution; (3) Flies have produced a lot of pesticides. Resistance, resulting in the more difficult to defend and the more difficult to kill
And although there are many studies on the repellent of flies, there is still a lack of a standardized device and method that can be popularized and applied.

Embodiment 1

[0027] In 10 test wells, add 15ml of sweet and sour solution respectively, add 2ml of 15% DEET (DEET) in 5 of them, mix well, as the treatment group; add 2ml of distilled water in the remaining 5 test wells as a control group, arranged as figure 1 shown. 3 days after eclosion, 15 male and female flies of the housefly were inserted, allowing them to freely choose to feed. Turn on the camera collection device on the top of the screen and the data collection device of the computer, take pictures every 30s, and keep recording for 30min. In addition to counting the number of houseflies in each hole in each time period, the total time spent by houseflies in each hole was counted. The calculation formula is: the total time of houseflies feeding in each hole (min) = ∑ (the number of houseflies in each time period × 5). The results showed that the average total time of houseflies in each control hole was 155.0 ± 16.1min, while the average total time of houseflies in DEET treatment h...

Embodiment 2

[0029] In 10 test wells, add 15ml of sweet and sour solution respectively, add 2ml of Zhaoshanbai ethanol extract into 5 of them, and mix well, as the treatment group; add 2ml of ethanol into the remaining 5 wells as the control group, arranged as figure 1 shown. 3 days after eclosion, 15 male and female flies of the housefly were inserted, allowing them to freely choose to feed. Turn on the camera collection device on the top of the screen and the data collection device of the computer, take pictures every 30s, and keep recording for 30min. In addition to counting the number of houseflies in each hole in each time period, the total time spent by houseflies in each hole was counted. The calculation formula is: the total time of houseflies feeding in each hole (min) = ∑ (the number of houseflies in each time period × 5). The results showed that the average total time of houseflies in each control hole was 150.0 ± 9.5min, while the average total time of houseflies in DEET trea...

Abstract

The invention discloses a screening system of fly repellent. The system comprises a computer, an image collecting device and a testing cage. The computer is connected with the image collecting device through a data line. The top of the testing cage is provided with an image collecting hole. The image collecting device is fixed to the image collecting hole. The six faces of the testing cage are each provided with a piece of 30-mesh gauze. A mesh opening is formed in the gauze on one side of the testing cage and connected with a mesh sleeve. A testing plate is arranged in the testing cage and provided with two rows of testing holes, and the distance between the two rows of testing holes is 3 cm. Each row of testing holes include five testing holes, and the distance between every two adjacent testing holes in the same row is 2 cm. The testing holes are cylindrical. A screening method includes the following steps of firstly, injecting a spawning medium; secondly, putting in female houseflies; thirdly, collecting data; fourthly, analyzing data. Compared with the prior art, the screening system and method are ingenious in structural design, convenient to use, practical, short in screening time, rapid in result analysis and capable of being operated, applied and popularized in a standardized mode.

Description

technical field [0001] The invention relates to a screening system, in particular to a screening system and method for a fly repellent. Background technique [0002] Flies are important vector organisms, which can mechanically transmit various diseases such as dysentery, typhoid, cholera, tuberculosis, trachoma, polio, hepatitis and parasitic diseases or pollute human food, cause visual pollution, threaten human health, and interfere with human beings Life. The prevention and control of flies is not only an important content of preventive medicine, but also an important content of building a civilized and healthy town, which is necessary for developing tourism, creating a good investment environment, and attracting foreign capital. At present, the control of flies is basically based on chemical control, but the chemical control of flies has the following problems: (1) Since flies mostly live in human-inhabited areas and the surrounding environment, there are many overlaps w...
