Carnation moth

Systematic position
The carnation moth (Hadena compta) belongs to the family Noctuidae within the order Lepidoptera. This species is widely recognized in temperate regions of Europe and Asia, where it specializes in attacking plants specifically from the Caryophyllaceae family.

Host plants
The primary targets for this pest are plants belonging to the Caryophyllaceae family. In agricultural and horticultural settings, the moth is particularly problematic for various species of the Dianthus genus (carnations), as well as certain wild species like bladder campion, which can serve as host plants.

Biology and life cycle
The life cycle of the carnation moth includes four stages: egg, larva (caterpillar), pupa, and adult. The insect typically overwinters in the pupal stage within the soil. Adult moths are nocturnal and emerge during the summer months, immediately seeking out suitable flower buds to lay their eggs.

Nature of damage
The caterpillars are the destructive stage of this pest. They bore into the developing flower buds, feeding on the internal tissues, seeds, and ovaries. This feeding behavior causes significant damage to the floral structure, often resulting in failed flowering or the complete destruction of the seed crop.

Control measures
Effective management of the carnation moth requires an integrated pest management strategy:

• Cultivating and tilling the soil in the autumn to disturb and kill overwintering pupae.
• Hand-picking and disposing of infested buds to prevent further larval development.
• Applying appropriate contact or systemic insecticides during the peak hatching period of the caterpillars.
• Maintaining field hygiene by removing alternative host weeds from the surrounding areas.
