Michaelsens termite

Systematic position. Coptotermes michaelseni belongs to the order Isoptera and the family Rhinotermitidae. These social insects are highly evolved wood-feeders that maintain complex colony structures, often nesting deep underground or within the heartwood of mature trees.

Crops damaged. This species primarily targets forest trees, ornamental species, and agricultural timber structures. They are particularly known for their devastating impact on eucalyptus plantations and various orchard trees, where they feed on root systems and internal wood tissues.

Biology and life cycle. The colony cycle involves a highly organized division of labor between workers, soldiers, and reproductives. New colonies are established during swarming events, where winged alates emerge, mate, and seek suitable nesting sites in soil or decaying woody material, marking the beginning of a long-term developmental phase.

Damage patterns and economic impact. The primary concern with Coptotermes michaelseni is their cryptic feeding behavior. By hollowing out the interior of tree trunks while leaving the outer bark and wood layers intact, they weaken the structural integrity of the plant, often leading to sudden tree collapse and severe economic losses in forestry and agriculture.

Control measures. Management of this pest requires an integrated approach to disrupt the colony's stability:

• Deployment of slow-acting toxicant baits to ensure colony-wide elimination.
• Implementation of soil barriers treated with long-lasting termiticides.
• Regular monitoring programs using cellulose-based baits in high-risk areas.
• Removal and destruction of infested wood to mitigate the risk of colony expansion to healthy plants.
