Formosan subterranean termite

Systematic position: The Formosan subterranean termite (Coptotermes formosanus) is classified within the order Isoptera and the family Rhinotermitidae. It is a highly invasive termite species known for its massive colony sizes and exceptional ability to destroy both structural cellulose and living timber.

Crops and plants affected: While primary damage is often associated with wood products, these termites frequently attack live trees in orchards, plantations, and urban landscapes. They feed on roots and the inner heartwood of various tree species, leading to structural instability and eventually the death of the plant.

Biology and life cycle: The colony thrives through a sophisticated social structure consisting of a queen, king, workers, soldiers, and reproductives. Unlike many other species, Coptotermes formosanus is capable of forming satellite colonies, which allows it to expand rapidly through soil and survive in diverse environmental conditions.

Nature of damage and economic impact: Damage is characterized by the consumption of internal woody tissues while leaving the outer bark intact, making the infestation difficult to detect in the early stages. By compromising the vascular system of trees, these termites cause sudden decline and physical collapse, resulting in significant losses for tree crops.

• Application of soil-applied termiticides to create chemical barriers.
• Deployment of baiting systems that utilize slow-acting insecticides for colony elimination.
• Regular visual monitoring for the presence of earthen mud tubes on tree trunks.
• Sanitation practices, including the removal of infested logs and debris from the growing area.
