Description

Technical Field

[0001] The utility model relates to the technical field of trapping equipment, in particular to a fruit fly trapping device. Background Art

[0002] Fruit flies are a general term for insects of the families Drosophilidae and Tephritidae in the order Diptera. There are many species, a wide distribution, and strong reproductive capacity. They cause great damage to agricultural production. When the larvae hatch, they will feed on fruits. As the eggs hatch, the fruits will gradually become wet and rotten and concave, losing their edible and economic value, affecting their quality and market sales. In order to reduce the damage caused by fruit flies to fruits, growers usually use fruit fly traps to prevent and control them.

[0003] At present, a fruit fly trap published in China with the publication number CN202635394U includes a bottle body and a bottle cap, which is characterized in that: the bottle body and the bottle cap are threadedly connected, the bottom of the bottle body has an opening, and the opening has a pipe upwardly connected to the inside of the bottle body; the bottle cap is provided with a hook or a tether hole. The fruit fly trap contains a trapping agent, which uses the chemotaxis of fruit flies to trap and kill adult fruit flies, and can be used for monitoring and preventing fruit flies in the field.

[0004] In actual use, when fruit flies are lured into the bottle and killed, they adhere irregularly to the inner wall of the bottle, making it difficult to clean the fruit flies. There is also a problem that it is inconvenient to collect and kill the fruit flies while they are alive. Therefore, we propose a fruit fly trapping device to solve the above problems.
