Ena

The genus Ena belongs to the family Enidae, comprising land-dwelling gastropod mollusks. These pulmonate snails are commonly found in humid habitats, leaf litter, and agricultural fields where high moisture levels provide favorable conditions for their survival, growth, and rapid reproduction.

This pest affects a wide range of agricultural and ornamental crops. Significant damage is typically inflicted on vegetable crops, berry bushes, and young cereal seedlings. The mollusks feed on leaf tissues, creating irregular holes, and damage young stems and shoots, leading to stunted growth or total plant mortality.

The biology of this species is highly dependent on environmental moisture. Ena snails are primarily nocturnal or crepuscular, spending the day hidden in the soil or under organic debris. They overwinter as adults or larvae in soil cracks or beneath leaf litter, resuming their activity in the spring when stable warm and wet weather conditions arrive.

The damage is easily identified by distinct signs: shiny, dried mucus trails left on the leaf surfaces. The economic impact is observed through reduced market quality of vegetable produce and total loss of seedlings, which can lead to sparse crop stands and substantial harvest losses during periods of population outbreaks.

An effective protection strategy combines cultural and chemical methods:

• Regular weeding to remove shelters where mollusks hide during the day.
• Optimizing irrigation practices to prevent excessive moisture accumulation.
• Installing physical barriers such as crushed eggshells, lime, or gravel around crops.
• Applying specific molluscicides based on iron phosphate or metaldehyde when pest pressure exceeds economic thresholds.
