Aciculidae
Systematic position: The Aciculidae family belongs to the order Gastropoda (snails). These are small land-dwelling pulmonary mollusks that can pose a threat to garden and horticultural crops in high-humidity conditions. They are typically found in moist soil litter and are characterized by their distinct, needle-like or cylindrical shells.

Aciculidae
Crops affected: Aciculidae primarily attack vegetable crops, young seedlings of ornamental plants, and berry bushes. They pose a significant threat in greenhouses and nurseries, where constant humidity and moderate temperatures provide optimal conditions for their reproduction and feeding on delicate plant tissues.
Biology and life cycle: The life cycle of these mollusks is heavily dependent on the moisture level of the substrate. They reproduce by laying eggs in moist soil or under organic debris. Their development does not involve the complex metamorphosis seen in insects; the hatchlings start feeding on soft plant tissues almost immediately, growing gradually throughout their life span.
Nature of damage: The pest feeds mainly on the epidermis of leaves and young, succulent shoots, leaving behind characteristic scrapings and perforations. Damaged plant tissues often become entry points for secondary fungal infections and bacterial rots. During periods of mass proliferation, Aciculidae can destroy entire nursery beds in just a few days.
Protection measures: Control strategies rely on a combination of cultural and chemical methods. Maintaining cleanliness by removing weeds and organic debris that provide shelter is crucial. Physical barriers, such as dry sand, grit, or ash around garden beds, can effectively deter them. In cases of high infestation, specialized molluscicides containing metaldehyde or iron phosphate are recommended.
