Exora lusitanica

Exora lusitanica is a dangerous insect species from the order Coleoptera, belonging to the leaf beetle family (Chrysomelidae). This pest is characterized by its specific food preference, making it a notable threat to certain agricultural crops within its distribution range.

The primary food source for this pest consists of plants from the Solanaceae family. Exora lusitanica inflicts the most significant damage on vegetable crops, particularly potatoes, tomatoes, and eggplants, as well as various wild relatives that serve as reservoirs for the population during the off-season.

The biology of the pest is defined by distinct seasonality. The life cycle involves complete metamorphosis: egg, larva, pupa, and adult. Adults overwinter in the topsoil layer or beneath plant debris, becoming active with the arrival of stable warm temperatures in the spring, when the period of intensive feeding and egg-laying begins.

Damage symptoms manifest as specific defoliation of leaf blades. Larvae and adults of Exora lusitanica skeletonize the leaves by chewing irregular holes, which leads to a decrease in the plant's photosynthetic activity, stunted growth, and significant yield losses during mass outbreaks.

Integrated pest management strategies are recommended for the control of this beetle:

• Adherence to crop rotation by excluding solanaceous crops from infested fields.
• Deep autumn plowing to eliminate overwintering stages.
• Application of contact-systemic insecticides when the economic threshold of damage is exceeded.
• Regular weeding of wild solanaceous host plants in and around fields.
