Trichoniscidae

These pests primarily target tender young plants, including vegetable seedlings, leafy greens, and ornamental flowers. They thrive in areas where plants are in close contact with moist soil or decomposing organic matter. Because they prefer high-humidity conditions, they often congregate around irrigation pipes, pots, and damp corners of a greenhouse, posing a risk to the root zones of the plants.

The biology of Trichoniscidae is characterized by nocturnal activity and a secretive nature. They possess a brood pouch in which the female carries the eggs and developing young. Once hatched, the juveniles undergo several molts to reach maturity. Their development is accelerated by the warm, humid, and stable conditions found within protected cultivation systems, allowing for rapid population growth.

The damage caused by these crustaceans is often manifested as rasping or gnawing on stems and root systems. By removing the epidermis or attacking young roots, they facilitate plant desiccation and stunted growth. Furthermore, their presence introduces pathogens to the plant tissues, leading to secondary fungal infections or rot, which can result in the rapid loss of seedling batches.

Implementing an integrated pest management (IPM) strategy is crucial for controlling Trichoniscidae:

• Improve greenhouse sanitation by removing old plant debris and organic waste.
• Modify irrigation practices to reduce excessive moisture on the soil surface.
• Deploy physical barriers or traps, such as dampened boards, to collect and remove them manually.
• Apply targeted insecticides approved for Isopoda if population thresholds exceed acceptable levels, focusing on the soil surface and plant base.
