Conotrachelus seniculus

Systematic position of Conotrachelus seniculus places it within the order Coleoptera and the family Curculionidae. These weevils are recognized as significant agricultural pests that require specific monitoring and management practices to mitigate their impact on production.

This pest primarily attacks crops belonging to the Rosaceae family. Its life cycle is closely linked to the phenology of these host plants, focusing on the fruit-bearing stages where it causes the most significant damage to the developing harvest.

The biology and life cycle involve a complete metamorphosis consisting of four stages: egg, larva, pupa, and adult. Adults overwinter in protected areas, emerging in the spring to feed on foliage and floral buds before mating and oviposition occurs directly in the young, developing fruit.

The nature of damage is primarily caused by larval feeding inside the fruit. This feeding creates internal tunnels, which disrupts the fruit's development, leading to premature fruit drop, secondary fungal infections, and total loss of marketability for the affected produce.

Protection measures include a combination of cultural and chemical strategies:

• Strict orchard sanitation by removing and destroying fallen fruit.
• Cultivation of the soil beneath tree canopies to disrupt pupation sites.
• Use of pheromone traps for population monitoring and detection.
• Application of targeted insecticides based on economic thresholds during the peak activity period.
