Glyptotermes neotuberculata

Glyptotermes neotuberculata is a species of drywood termite belonging to the family Kalotermitidae. Unlike subterranean termites, this species does not require soil contact to survive, allowing it to complete its entire life cycle deep within the timber or heartwood of living and dead trees.

The host range for this pest includes a wide variety of hardwood and softwood species. They are frequently found in ornamental trees, forestry plantations, and the wooden frameworks of structures. The pest thrives in dry conditions and can persist within wood for extensive periods, often going undetected until significant structural damage has occurred.

The biology of Glyptotermes neotuberculata revolves around a sophisticated caste system. A mature colony consists of reproductive individuals, soldiers, and nymphs (workers). They build complex networks of galleries that follow the grain of the wood. Reproduction is slow but steady, and the colony expands by excavating more wood as food resources decrease.

The damage caused by this termite is internal and often hidden from external view. The primary sign of infestation is the presence of frass, which are small, pellet-like fecal droppings that accumulate near entry or exit holes. The loss of structural integrity in tree trunks or lumber makes the host highly susceptible to mechanical failure and environmental stress.

Effective management requires a combination of identification and chemical control methods. Recommended strategies include:

• Regular inspection of bark and wood surfaces for signs of frass accumulation.
• Removal and destruction of heavily infested limbs or timber.
• Direct injection of targeted insecticides into the colony’s galleries.
• Application of wood preservatives to prevent new colonizations.
• Implementing structural barriers to protect valuable landscape trees and buildings.
