Potato, Irish-Garden symphylan

Scutigerella immaculata

Pest description and crop damage Small, white, centipede-like animals in the soil. This arthropod is a pest of potatoes in isolated pockets in the PNW, especially west of the Cascade Mountains. Damage consists of scars on the tuber skin, which are undesirable in the marketplace. Because damage from symphylans and flea beetles is very similar, it is important to be sure that symphylans are present prior to any treatments aimed at their control.
