Subulinid snails
The family Subulinidae belongs to the order Stylommatophora. These small land snails are significant pests in agricultural environments, particularly in greenhouses, nurseries, and botanical gardens. Due to their small size and reproductive capacity, they are often considered problematic invasive species in many regions worldwide.

Subulinid snails
Subulinids are known as polyphagous pests, capable of feeding on a wide variety of plant materials. They frequently attack seedlings, young vegetable transplants, ornamental plants, and various soft-tissue leafy crops. Their ability to thrive in moist potting soil makes them particularly destructive in container-grown operations.
The biology of these molluscs is characterized by hermaphroditism, which allows for rapid population expansion. They typically lay eggs in moist soil or decaying organic matter. The young snails develop quickly, often reaching maturity within a few months, and continuously forage on nearby plant tissues to support their rapid growth cycle.
Damage caused by subulinids involves the consumption of leaves, shoots, and roots of young plants, leading to stunted growth or total plant loss. Their feeding activity leaves distinct irregular holes or skeletonized foliage. Furthermore, their presence introduces the risk of transmitting plant pathogens through their trail of slime and movement across different parts of the crop.
Integrated pest management (IPM) is essential for controlling subulinids effectively. Key strategies include:
- Improving greenhouse sanitation to remove debris.
- Regulating humidity levels to create less favorable conditions for survival.
- Using bait stations with molluscicides such as iron phosphate.
- Implementing physical barriers or dry zones to prevent migration between pots.
