Artichoke moth

Systematic position: Cnephasia cinareana belongs to the order Lepidoptera, family Tortricidae. This species is a specialized pest that is commonly known as the artichoke moth due to its primary association with the Asteraceae family, specifically targeting artichoke plants.

Crops affected: The pest is most dangerous to artichoke plantations, but it can also be found on other wild and cultivated members of the Asteraceae family. The larvae exhibit high host specificity, which poses a significant threat to commercial artichoke production operations.

Biology and life cycle: The life cycle of this moth is typical for the genus Cnephasia. It usually overwinters as young larvae or eggs, depending on the climatic conditions of the region. In spring, the larvae emerge and begin feeding on plant tissues, passing through several larval stages before pupating inside folded leaves or flower buds.

Damage patterns and economic impact: The primary damage is caused by the larvae. They mine young leaves, often webbing them together, and burrow into developing flower buds. Such damage causes deformation of the floral parts, reduces the commercial quality of the produce, and results in significant yield losses, making the crops unsuitable for market.

Control measures: Effective control relies on an integrated approach combining agronomic and chemical methods. It is recommended to:

• Monitor population levels using pheromone traps.
• Remove and destroy crop residues after harvest.
• Apply biological or chemical insecticides during the period of mass larval emergence.
• Implement crop rotation to disrupt the pest's life cycle.
