Endoclita chalybeatus

Endoclita chalybeatus is a wood-boring moth belonging to the family Hepialidae, order Lepidoptera. This insect is recognized as a significant pest in agricultural settings, particularly known for its ability to damage the structural integrity of various woody plants through its larval feeding habits.

The host range of this pest typically includes economically important crops such as coffee, cocoa, and tea, as well as various fruit and forest trees. By targeting the stems and branches of these plants, the larvae can cause widespread impact on plantations, leading to significant yield losses in affected agricultural regions.

The life cycle of Endoclita chalybeatus follows a complete metamorphosis pattern. The female moth deposits eggs on the host plant or nearby soil, and upon hatching, the larvae immediately seek entry points into the stem. The larval stage is the most destructive phase, characterized by extensive boring activities that can persist for an extended period.

The damage caused by this insect is primarily internal. As the larvae tunnel through the sapwood, they disrupt the vascular tissues of the plant. This structural damage restricts the transport of water and nutrients, which often leads to the chlorosis of leaves, wilting of branches, and in cases of heavy infestation, the snapping of the main stem or total plant death.

• Periodic field inspections to identify frass or entry holes on stems.
• Mechanical extraction of larvae from galleries using thin wires or tools.
• Targeted application of systemic insecticides into the infested tunnels.
• Pruning and destroying severely damaged limbs to reduce pest population.
• Promoting biodiversity in the plantation to encourage natural biological control.
