Ligiidae

Crops and damage profile: These pests primarily target seedlings and delicate ornamental or vegetable plants. They cause physical damage by rasping the epidermis of stems and leaves near the soil surface. This feeding behavior often leads to stunted growth and provides entry points for various fungal pathogens, which can result in significant seedling loss.

Biology and life cycle: Ligiidae require high levels of moisture for respiration and reproduction. They are typically nocturnal and spend their daylight hours hiding under debris, pots, or damp organic matter. Their life cycle involves several molts as they grow from juvenile stages to reproductive adults, with populations thriving rapidly in consistently wet conditions.

Cultural management: The primary strategy for controlling Ligiidae is habitat modification. By reducing humidity levels and ensuring proper drainage, growers can create an environment unsuitable for these pests. It is essential to maintain a high standard of greenhouse hygiene to limit their survival opportunities.

• Improving ventilation to lower ambient humidity.
• Removing all organic debris, such as fallen leaves and decaying wood.
• Ensuring greenhouse floors are kept dry and free of standing water.
• Inspecting incoming plant shipments for signs of crustacean infestation.
• Utilizing chemical baits specifically formulated for Isopoda if necessary.
