Pomatiopsidae
Pomatiopsidae is a family of small gastropod mollusks that frequently inhabit wetlands, irrigation canals, and flooded agricultural areas. While widely recognized in biology for their medical importance, they are also significant agricultural pests capable of damaging aquatic and semi-aquatic crops by consuming plant tissue and disrupting irrigation systems.

Pomatiopsidae
Taxonomically, they belong to the order Littorinimorpha. These organisms are highly adapted to humid environments, making them particularly problematic in rice paddies and areas with high soil moisture. Their presence is often a limiting factor in the successful cultivation of water-dependent crops.
The biological cycle of these mollusks is water-dependent. They deposit eggs on submerged surfaces or wet soil. Upon hatching, the larvae undergo development in the aquatic environment, where they feed on organic matter and young shoots. Rapid life cycles allow them to exploit favorable conditions quickly, leading to massive population outbreaks.
The primary damage caused by Pomatiopsidae involves scraping the epidermal layers of plant stems and leaves. This mechanical damage hinders plant development, stunts growth, and creates entry points for fungal pathogens. Furthermore, their accumulation in irrigation networks can lead to reduced flow efficiency, which indirectly stresses the crop.
Protection strategies are primarily focused on habitat modification. The most effective methods include:
- Periodic drying of irrigation channels to eliminate breeding sites.
- Removal of aquatic weeds that serve as food and substrate for eggs.
- Careful monitoring of water quality to prevent mass colonization.
- Targeted use of molluscicides, provided they are environmentally safe and permitted for agricultural use.
