Xerolenta

Xerolenta, specifically the species Xerolenta obvia, belongs to the class Gastropoda and the family Helicidae. These terrestrial pulmonate snails are typically found in arid and semi-arid environments, favoring open fields and grasslands where they can survive dry spells.

These mollusks are polyphagous pests, capable of causing significant damage to a wide range of agricultural crops. They frequently infest cereals, legumes, oilseed crops like sunflowers and rapeseed, and various horticultural plants. Mass occurrences can lead to the total loss of seedlings and young shoots.

The biology of Xerolenta is closely tied to moisture levels. While they can endure dry conditions by entering aestivation and attaching themselves to plant stems, they become highly active during wet weather. This behavioral trait often leads to the contamination of harvests during mechanized reaping.

The damage caused involves the consumption of leaves, stalks, and fruits. Beyond physical destruction, these snails contaminate crops with mucus and feces, significantly reducing product quality and increasing the risk of secondary infections, such as fungal pathogens, on the plant surfaces.

Integrated pest management (IPM) is essential for controlling Xerolenta. Key strategies include cultivating soil to disrupt their habitats, maintaining field margins free of dense vegetation, and the timely application of molluscicides, particularly those containing iron phosphate or metaldehyde, once thresholds are reached.
