Pest Species

NATIVE UK SLUG SPECIES CONSIDERED A HORTICULTURAL PEST:

The Grey Field Slug (Deroceras reticulatum), a pest on agricultural land as it feeds mostly on seeds and plants above ground, and is a major threat to cereal crops.

The Brown Field Slug (Deroceras invadens)

The Brown Soil Slug  (Arion distinctus), a major pest of potatoes and attacks both leaf and root crop.

The Blue-Black Soil Slug (Arion hortensis)

The Budapest Keeled Slug (Tandonia budapestensis), will feed on newly drilled seeds underground and will badly affect crops such as potatoes. As it spends most of its time underground it can prove very difficult to control.

The Large Black slug (Arion ater), will eat seedlings on agricultural land in spring, but it is much less damaging than the other pest species.

The Large Red Slug (Arion rufus)


NON-NATIVE INVASIVE UK SLUG SPECIES CONSIDERED A HORTICULTURAL PEST:

The Spanish Slug (Arion vulgaris)

In the early spring of 2012 Dr Ian Bedford, Head of Entomology at the John Innes Centre, Norwich, noticed an unusually high number of slugs in his garden and observed they were not just eating plants but other things too such as dog excrement and dead animals. After some further research and collaboration with Dr Les Noble, University of Aberdeen, it was discovered that these were Spanish slugs, Arion vulgaris, and this was the first mass observation of this species within the UK.

The Iberian Threeband Slug (Ambigolimax valentianus)
