The tiny inventor failed three times before successfully processing the fly-killing machine

Being the youngest student in the contestants who won the "National Youth and Children Study Techniques for Young People and Children in 2016" contest, Pham Nguyen Bao Duy (Grade 3 student, Dong Phu Primary School 1, commune) Dong Phu, Chau Thanh district, Hau Giang province has made many delegates unexpectedly present.

My initiative is evaluated as new, unique, easy to put into practical operation, the cost of producing turnaround but the results are very high.

Yellow fly is a kind of toxic insect that damages very quickly fruits, therefore, gardeners often use traditional methods such as using fly glue, chemical spray, hanging bananas . But the results are not high, costly.

Bao Duy mind of rusticness: "Every time I go to the mango garden, I see many yellow flies biting fruits but there is no way to kill them. If I use drugs, I will lose money and affect the quality of fruits because of the drug except pests, from which I am determined to make the gold fly killing machine . ".

Only with fly bait bait with purple leaves.

From that thought, Duy discovered in his hometown a lot of abandoned purple trees but attractive to insects, especially yellow flies because of this crumbling aroma. She began her journey of making gold fly catchers with this leaf.

Duy's products are simple with the main parts including: tripod; the body has a brass for wind when the rear rotor rotates under the effect of natural wind; the leaves of the leaves are puree, and the bottom is the pot of the golden fly.

When the wind rotates the rear rotor, start the machine.

The aroma of the wind-blown purple leaves in the air will attract the golden fly to and be sucked into the container, users only have to destroy them in their own way.

Commenting on Duy, Ms. Nguyen Thi Ut, her mother said: "Duy has an interest in the initiative from a young age, is always exploring, discovering new and strange things in books, newspapers and television. I also create conditions for him to promote his interests . ".

Bao Duy added: "If you don't see it so many times, it will be a good time for you to be a third time, I think that if you want to succeed, you must be hard-pressed, not depressed by all failures .".

Currently the cost of installing this flyer is only about 100,000 VND / machine and has been successfully applied by many local farmers.

Duy with his "Golden fly" catcher has just won the national 3 of the youth and children science and technology fair in 2016.

The advantage of the machine is very light, mainly made of plastic, aluminum, simple structure, no need of fuel, easy to disassemble and maneuverable, very convenient in all terrain.

It is suitable for farmers, helping gardeners save spraying time, reduce production costs, limit the attack of gold flies to affect productivity and product quality.

Mr. Le Van To (living in Phu Hung hamlet, Dong Phu commune) commented:

"This device is simple, inexpensive but very effective, I have tried on 6 crops of Taiwanese mango, resulting in killing up to 80% of the inherent gold flies, which are cheap and safe for fruits . ".

The good news came, my "golden fly-catch" model has just won the third prize in the 2016 national youth and children science and technology fair in Hanoi; become a great encouragement for Duy.

In Pham Nguyen Bao Duy class, he studied all subjects very well, in which he was very interested in Math and English. In my free time, I found myself creating new topics, before I broke up and smiled very well and said:

"I am researching a model of" wind-powered motorcycle "with the expectation that people will no longer have to buy gas when using it and the environment will be less toxic due to the smoke emitted from motorcycles".

A new idea is very funny, practical and has been formed in the thinking of this 3rd class "inventor" !
