Yinchuan street hangs fly "artifact" More than 5 million fly trappers a year

What is the birdcage hanging on the tree? The mysterious objects that appeared on the streets of Yinchuan once caused widespread public speculation. The reporter learned on July 2 that one year later, this “artifact” named the fly trap had quietly caught more than 5 million caterpillars, which had created great merit for the establishment of a sanitation city in Yinchuan. In August last year, a few birdcage-like objects were hung in the trunk of the streets of Yinchuan within a few days. They have a cage-like blue gauze, a plexiform gauze inside, and a black plate at the bottom, with some paste in it. Its appearance quickly led to public speculation. Some people made special guesses on the Internet. Most people think of it as a bird cage for feeding birds; some speculate that it is catching fly mosquitoes. It has also been pointed out that if it is insect trapping, it must be insecticide poison, and this object is only less than 2 meters above the ground and is unsafe.

In everyone's doubts, the mystery work silently for a year. Yesterday, Director Yin Wei of Yinchuan City introduced that the objects that were hung last year were fly traps and that more than 5 million have been trapped in the past year. He said that this kind of fly trap is a physical fly control device that Yinchuan City introduced from the field last year. When the climate continues to stabilize a certain high temperature for 10 days to more than half a month, the conditions for the rapid propagation of the fly are achieved. In August last year, Yinchuan City Aiwei Office purchased 3,000 fly traps and drew 1,400 vehicles in Jiefang Street, Beijing Road, Zhongshan Street, Tongxin Road, and farmers’ markets where people were densely populated and could not easily be killed by pesticides in Yinchuan. . The fly traps are filled with fly food and are non-toxic. Dr. Qu said that from July to September when the fly cages are “work” busy, they catch 30 to 50 flycatchers per day on average. After 3 days, they need to clean up the flies that they have captured and change their feed. "Each cage is only about 30 yuan, but it plays a big role."

According to reports, on July 20, the Yinwei Aiwei Office will again put 1,600 fly traps in the city.

Fly trap

The working principle of the fly trap is to use the characteristics of the fly taking off and flying upwards. When the fly smells the smell of the food, it flies from the edge of the plate to the plate. After the food bait takes off, it is covered by the vertebral gauze and has to be taken from the vertebrae. The small hole at the top of the net enters the cage-like gauze that surrounds it. It takes a long time to fly and it is starved to death.
