KON TUM (VNS)— Nearly 1,000ha of pine forest aged from 8-12 years belonging to the Southern Paper Company in the Central Highlands province of Kon Tum is being attacked by pine sawflies.
The sawflies, with scientific name of Nesodiprion biremis, are eating 20-70 per cent of the pine trees' leaves with a density of about 2,000 sawflies a tree.
The company has sprayed chemicals but the pesticide didn't work.
