Odontotermes feae

Odontotermes feae is a prominent species of fungus-growing termites belonging to the Termitidae family. These insects are ecologically significant but represent a major economic threat in agricultural settings due to their ability to consume both dead organic matter and living plant tissues.

This pest affects a wide range of agricultural commodities, including tea, coffee, fruit trees, and various tropical crops. By targeting the root systems and the heartwood of trees, Odontotermes feae can cause extensive crop failure, particularly in newly planted orchards or nurseries where young plants are most susceptible.

The biology of this species involves a highly structured caste system, including workers, soldiers, and reproductives. They maintain elaborate underground nest systems that provide a stable microclimate for their fungal gardens, which are essential for processing the cellulose they consume from host plants.

Damage is typically characterized by the presence of clay-like foraging galleries constructed over the surface of stems and trunks. These structures serve as protective corridors. Once these barriers are breached, it becomes evident that the termites have extensively excavated the internal tissues, often hollowing out the plant and causing it to collapse under stress.

Management strategies for Odontotermes feae require a multi-faceted approach:

• Application of systemic insecticides to the soil surrounding the root zone.
• Excavation and destruction of central termitaria to eliminate the queen.
• Cultural practices such as removing dead logs and debris from fields to reduce habitat.
• Utilization of bait stations containing slow-acting chitin synthesis inhibitors to collapse the colony.
