Woodlice (Armadillidae)

These pests primarily target seedlings, soft-stemmed vegetables, and low-growing fruits. Common victims include cucumbers, tomatoes, strawberries, and various nursery seedlings. In greenhouses, they can be particularly destructive to potted plants and mushrooms, consuming both roots and foliage, which weakens the host plant.

The biology of woodlice is defined by their nocturnal nature and reliance on damp, decaying organic matter. They reproduce via eggs kept in a specialized brood pouch. They undergo several molts during their growth, and their populations can explode quickly in favorable conditions such as poor ventilation and organic debris accumulation.

The damage caused by Armadillidae is characterized by irregular holes in leaves and stems, and in severe cases, the complete consumption of tender roots. This feeding activity not only physically damages the plant but also creates entry points for soil-borne pathogens and fungal infections, ultimately stunting plant growth.

Integrated pest management (IPM) is essential for woodlouse control.

• Improve greenhouse drainage and increase air circulation to reduce humidity levels.
• Clear all debris, dead leaves, and rotting wood from planting areas to eliminate hiding spots.
• Use physical barriers like copper tape or diatomaceous earth around plant stems.
• Deploy targeted baits or professional pest control applications during early stages of infestation to prevent population growth.
