The larvae of some species feed on growing tips and roots or chew and bore into stems [...] serious damage in many greenhouse and field crops by feeding on leaves, roots, or fruits, leading to reduced growth and yield loss. Effective beetle control [...] traps Beneficial nematodes actively seek out and eliminate beetle larvae in the soil, while traps help monitor and reduce adult beetle populations. With Koppert’s
