Trachelipodid woodlice

These pests primarily target crops that thrive in damp conditions, including various vegetables like cucumbers, tomatoes, and peppers, as well as strawberries and root vegetables. Seedlings and young plants are particularly vulnerable, as they can be decimated during the nocturnal feeding activities of the woodlice.

The biology of Trachelipodidae is defined by a reliance on moisture. They breathe via pseudotracheae, which require a certain level of humidity to function effectively. The females carry eggs in a ventral brood pouch called a marsupium. After hatching, the juveniles undergo several molts before reaching maturity, spending their lives hidden under debris, organic matter, or within the upper layers of damp soil.

The damage caused by these pests includes irregular holes in foliage, stems, and fruits lying near or on the ground. Beyond physical consumption, woodlice often facilitate the entry of pathogens into plant tissues. Their presence in high densities can severely impact plant development and lead to significant post-harvest losses, especially in greenhouse environments.

Effective management strategies should focus on environmental manipulation and integrated pest control:

• Reducing soil moisture through improved drainage systems.
• Clearing the area of organic debris, boards, and weeds to eliminate breeding sites.
• Implementing regular soil aeration to disrupt their environment.
• Utilizing physical traps, such as overturned pots or damp cardboard, to collect and remove individuals.
• Applying specific molluscicides or authorized insecticides if the infestation reaches economic thresholds.
