Click beetle Alaus prosectus

Systematic position. This species is a member of the order Coleoptera and the family Elateridae, commonly known as click beetles. As a soil-dwelling insect, it represents a group of beetles that can transition from saprophagous feeding to phytophagous behavior, causing notable agricultural concern.

Crops affected. The pest affects a wide range of horticultural and field crops. It is particularly damaging to seedlings and young plantations, where the root systems are tender and easily accessible for the larvae. The presence of the pest can significantly impact the survival rate of young crops in various soil types.

Biology and life cycle. The life cycle involves complete metamorphosis: egg, larva (wireworm), pupa, and adult. The larval stage is the longest, often lasting several years depending on temperature and moisture levels. They migrate vertically in the soil profile throughout the season based on soil humidity.

Nature of damage and pest status. Larvae cause damage by consuming roots, tubers, and basal stems. This feeding disrupts the plant's vascular system, leading to wilting, stunted growth, or sudden death. The resulting damage reduces both the yield quality and the overall plant density in the affected fields.

• Deep cultivation: disrupts larval habitats and exposes them to predators.
• Crop rotation: rotating away from susceptible host plants to break the pest cycle.
• Soil-applied insecticides: effective in high-pressure fields during the sowing stage.
• Pheromone monitoring: helps identify peak adult flight to time potential interventions.
