Arionidae

Host plants: Arionidae are polyphagous pests, meaning they feed on a wide range of plants. They primarily target leafy vegetables like lettuce and cabbage, succulent crops such as strawberries, and various root vegetables. Greenhouse crops and ornamental plants are also highly susceptible to their feeding activities.

Biology and life cycle: These slugs are hermaphroditic and highly prolific, allowing for rapid population growth under favorable moist conditions. They are nocturnal and spend daylight hours in cool, damp places like soil crevices or under mulch. Their eggs are laid in moist soil, and the young emerge to feed immediately, reaching maturity in a matter of weeks.

Damage and harmfulness: The feeding mechanism involves rasping plant tissues with their radula, resulting in irregular holes and jagged leaf margins. They often destroy seedlings completely. Furthermore, the slime trails they leave behind reduce the marketability of produce and serve as vectors for various plant pathogens and fungal infections.

Control measures: Effective management requires a combination of strategies:

• Maintaining good sanitation by removing weeds and plant debris.
• Creating physical barriers such as copper tape or crushed eggshells.
• Using iron phosphate-based baits for targeted control.
• Encouraging natural predators like ground beetles, frogs, and hedgehogs.
• Improving soil drainage to minimize the moist environment slugs thrive in.
