Also known as:
Pygmy beetle
Pygmy mangold beetle (Atomaria linearis). The Pygmy mangold beetle is a small, (dark) brown beetle measuring + 1.2 mm – hard to see. The beetles drill holes in the underground parts of seedlings. The drill holes form dark spots on the root. Plants grow too slowly and the plants will not survive a serious infestation..
The beetles overwinter in plant remains in the soil. Pygmy mangold beetles are mostly found on heavier soils. In the spring, the beetles go in search of (sugar) beets. In cold and damp months in spring, the damage is greatest: the beetles stay underground longer.
Beets and spinach are the host plants of the pygmy mangold beetle.
Control
Difficult to to control; once infested, recovery is not possible.
