Neotermes gestri

Systematic position. Neotermes gestri belongs to the order Blattodea, family Kalotermitidae. These insects are commonly known as drywood termites, characterized by their ability to thrive inside dry wood without needing a connection to the soil or external moisture sources.

Host plants. This pest targets various tree species, often attacking the trunk and larger branches of both ornamental trees and fruit-bearing woody plants. Because they can live within the heartwood, infestations often go unnoticed until the structural integrity of the plant is significantly compromised.

Biology and life cycle. A colony of Neotermes gestri resides entirely within the woody substrate. The life cycle involves a caste system where winged reproductives emerge to swarm, find new hosts, and establish colonies. Growth is typically slow, allowing a single colony to occupy and modify the interior of a tree for several years.

Damage and harmfulness. The primary damage is caused by the construction of extensive gallery systems within the wood. This boring activity disrupts vascular transport, weakening the tree's health and making it susceptible to secondary pests and fungal rot. Accumulations of fecal pellets (frass) expelled from the wood are a key diagnostic symptom.

Protection measures. Managing Neotermes gestri requires targeted and preventative actions:

• Regular inspection of bark and tree surfaces for holes and frass.
• Pruning and destroying infected branches to curb colony expansion.
• Localized insecticide treatments injected directly into active galleries.
• Maintaining overall plant vigor through proper fertilization and watering to minimize stress.
