Ancylolomia

Systematic position. Ancylolomia is a genus of moths belonging to the family Crambidae, order Lepidoptera. These insects are recognized as specialized pests that primarily target grasses and cereal crops in various agricultural regions worldwide.

Crops damaged. The larvae of this genus are known to cause damage to a variety of Poaceae family members. Economic losses are most frequently recorded in rice, maize, sorghum, and millet fields, where the larvae feed on young tissues and stems.

Biology and life cycle. The life cycle comprises egg, larval, pupal, and adult stages. Adult moths are typically nocturnal. The larvae exhibit unique behavior by constructing silk-lined tubes or burrows near the base of the plant or just below the soil surface, providing protection from predators and environmental stress during the day.

Character of damage and harmfulness. Larval feeding involves consuming the succulent stems and leaves of host plants. By cutting stems at the base, they often kill young seedlings or weaken older plants, leading to patches of dead vegetation within the field and significant yield reduction at harvest.

• Implementation of clean farming practices to reduce larval refuge.
• Tillage of soil after harvest to expose and destroy overwintering pupae.
• Regular field scouting to identify early signs of larval tube construction.
• Application of targeted insecticides based on local economic threshold levels.
