Jooksupardid pidavat ainukesed olema kes neid võimelised sööma on.
Siilid väidetavalt siiski söövad ning noorisendeid söövad ka muud:
"The Spanish slug, Arion vulgaris, has limited natural enemies, especially as an adult, due to its thick mucus layer. However, some ground beetles, certain birds, nematodes, and even other slugs like Limax maximus (leopard slug) are known to prey on them, particularly the juveniles. Hedgehogs can also consume them.
Here's a more detailed breakdown:
Natural Predators:
Ground Beetles: Pterostichus melanarius and Carabus nemoralis are known to consume Arion vulgaris eggs and juveniles, according to a study published on the National Institutes of Health (NIH) website.
Birds: Thrushes, mallards, and other ducks are known to eat them.
Nematodes: Phasmarhabditis hermaphrodita is a parasitic nematode that can infect and kill slugs.
Other Slugs: Leopard slugs (Limax maximus) will eat Arion vulgaris.
Hedgehogs: They are known to consume slugs.
Why it's difficult to control them with natural enemies:
The thick mucus layer of adult Arion vulgaris acts as a deterrent to many potential predators.
While juveniles are more vulnerable, the adult slugs can still be difficult to control through natural predation.
Using slug pellets, a common method, can also harm beneficial creatures like leopard slugs, which are natural predators.
Other important notes:
Arion vulgaris is an invasive species, and in some newly invaded territories, it may not have natural enemies to keep its population in check.
Some gardening practices, like keeping grass short and removing hiding places, can help reduce slug populations and make it easier for natural predators to find them.
Beneficial nematodes (like Phasmarhabditis hermaphrodita) can be used as a biological control method to target slugs specifically, according to the Royal Horticultural Society (RHS). "
