BEIJING, June 29 (Xinhua) -- Chinese researchers developed a device which kills pests with radio frequency, extending the storage period of nuts and dried fruit by more than a year, according to Friday's Science and Technology Daily.
The insecticidal device was developed by Xinjiang Academy of Agricultural Sciences, northwest China's Xinjiang Uygur Autonomous Region. It can kill all pests and their eggs in walnuts and almonds without recourse to any chemical treatment, according to the paper.
Around 300 kg of nuts or dried fruits can be treated by the device in one hour, without affecting quality.
Xinjiang has 330,000 hectares of walnut plantations. Moths and other pests do a lot of damage to walnuts in storage.
