Terahertz imaging technique reveals subsurface insect damage in wood

Insect infestation is becoming an increasingly costly problem to the forestry industry, especially in areas experiencing increased droughts and hot spells related to climate change. A new terahertz imaging technique could help slow the spread of these infestations by detecting insect damage inside wood before it becomes visible on the outside.

"Our approach could be used to detect early-stage insect infestation on the trunks of trees, in imported wood or on wood products in an early infestation stage," said research team member Kirsti Krügener, from HAWK University of Applied Science and Arts in Germany. "This could help keep out damaging insects from other countries and stop infestation before it spreads throughout a forest."
