Kill fruit flies with biotechnology

Scientists from the Plant Protection Institute and the Australian Center for International Agricultural Research (ACIAR) have collaborated and successfully researched a new method of eradicating fruit flies, effectively reaching approximately 100 % without toxic to the environment.

Specifically, scientists have studied and produced a type of protein baits that are hydrolysed yeast plus a certain amount of insecticides.

Using a protein spray method before each harvest is a positive and safe preventive measure. The use of protein baits is also very simple. If used to kill male flies, apply 2ml of attractant compound to the trap. Hanging traps on a shady tree at a height of 1.5-2m.

Each hectare hangs 20-30 traps, every six weeks change baits. If you want to prevent, except on a large scale, then mix it into water and spray it on the tree, periodically every 5-7 days.

Using bio-protein baits to kill fruit flies has been implemented by the Plant Protection Institute in some places such as Son La, Hoa Binh, Thua Thien Hue, Hai Duong, Hai Phong . with very positive results. The results of experiment of spraying protein baits except flies for nearly 100 ha of digging in Moc Chau - Son La showed that the number of fruit flies reduced to 4% while the control sample was 100%.

The Institute is continuing to deploy many other provinces in the country to prevent fruit flies.
