Pointed snail

The pointed snail (Cochlicella acuta) is a terrestrial gastropod mollusk belonging to the order Stylommatophora and the family Cochlicellidae. This invasive species has become a significant agricultural pest in various regions, particularly where Mediterranean-like climates provide ideal conditions for its survival and rapid population growth.

This snail is a polyphagous pest that targets a wide range of agricultural commodities. It is frequently found damaging cereal crops, including wheat and barley, as well as legumes, horticultural vegetables, and pasture grasses. Its ability to thrive in diverse environments makes it a persistent challenge for modern farming operations.

The biology of the pointed snail is characterized by a high sensitivity to moisture levels. Reproduction occurs during periods of sufficient humidity, with eggs deposited in the soil. During hot, dry summer months, the snails exhibit aestivation, climbing up stalks or climbing onto posts and fences to minimize water loss and escape high ground temperatures until the next wet season.

Damage caused by this snail includes the consumption of leaves, shoots, and grain kernels, which directly impairs plant development. Furthermore, the presence of these snails in harvestable material is a major issue, as they contaminate the produce with mucus and debris, which complicates processing and storage and often leads to the rejection of harvested batches.

• Implement comprehensive crop rotation strategies.
• Use shallow or deep tillage to expose snails and eggs to predators.
• Apply professional molluscicides, such as metaldehyde-based baits.
• Manage weeds around field edges to reduce snail refuges.
• Monitor population density regularly to determine threshold levels for action.
