Altica gravida flea beetle

Altica gravida belongs to the order Coleoptera and the family Chrysomelidae. This species acts as a specialized pest found on various wild and cultivated plant representatives, particularly those belonging to the Boraginaceae family and other herbaceous plants, depending on the geographical distribution range.

This pest primarily affects plants growing in steppe and forest-steppe zones. In agricultural ecosystems, it can cause damage to specific medicinal and essential oil crops, as well as to weeds that serve as reservoirs for pests and diseases on the areas adjacent to cultivated fields.

The biology of Altica gravida is closely linked to seasonal climatic cycles. Adult beetles overwinter in the upper soil layer or under plant debris. In the spring, once favorable temperatures are established, the insects emerge from diapause, begin active feeding, mate, and lay eggs on the leaves or stems of host plants.

A characteristic sign of damage is the appearance of numerous small, rounded holes in the leaf blades, often referred to in agronomy as shot-holing. When the population density is high, the leaves become skeletonized, which disrupts photosynthesis, stunts plant growth, and in severe cases, leads to total plant death.

Protection measures include a comprehensive approach: crop rotation, weed management, and deep autumn plowing to destroy overwintering sites. When the economic injury level is exceeded, the application of authorized systemic or contact-stomach insecticides is recommended, strictly following the pre-harvest intervals for safety.

• Regular field monitoring using yellow sticky traps.
• Application of pyrethroid and organophosphate-based insecticides.
• Implementation of agronomic practices to maintain crop vigor.
