Andraca

Systematic position: The genus Andraca belongs to the order Lepidoptera, specifically the family Drepanidae (hooktip moths). These moths are known for their distinct morphological features and their status as significant pests in tea-growing regions across Asia and other subtropical territories.

Host plants: The primary host for Andraca species is the tea plant (Camellia sinensis). Because of their host preference, they are frequently encountered in tea estates where they can cause economic losses by attacking the leaves, which are the main commercial product of the plant.

Biology and life cycle: The life cycle consists of four stages: egg, larva, pupa, and adult. The females typically deposit eggs on the abaxial surface of tea leaves. The larvae go through several instars, feeding primarily at night and showing high activity levels during the warmer months of the growing season.

Damage and pest status: The damage is caused by the caterpillars' intensive feeding behavior. They consume large portions of the leaf blade, often leading to total defoliation in severe infestations. This reduction in the leaf surface area directly impairs the photosynthesis process and reduces the overall yield and quality of the tea harvest.

Control measures: Management strategies for Andraca focus on integrated pest management (IPM). This includes regular monitoring of egg masses, mechanical removal, and the use of biological control agents such as Bacillus thuringiensis. Chemical control is reserved for outbreaks, prioritizing insecticides that align with organic or sustainable farming standards.

• Regular field scouting for early detection.
• Deployment of light traps for moth population monitoring.
• Promotion of natural predators like parasitic wasps.
• Timely application of bio-insecticides.
