Lepispilus sulcicollis

Systematic position Lepispilus sulcicollis belongs to the order Coleoptera and the family Tenebrionidae. This beetle is a representative of a specific entomofauna that, under certain environmental conditions, can act as a pest of various agricultural and wild plants.

Host plants of this species are primarily associated with herbaceous vegetation and certain vegetable crops. The pest prefers habitats with high soil moisture, where it can cause damage to the root system, root collar, and young seedlings, often leading to suppressed plant growth and stunted development.

Biology and life cycle of this insect are closely related to soil and climatic conditions. The life cycle involves complete metamorphosis: egg, larva, pupa, and adult (imago). Adult beetles lead a cryptic lifestyle, being primarily active during dusk or night, while the larvae develop in the topsoil layer, feeding on plant debris or living plant tissues.

Nature of damage involves gnawing the epidermis of stems and causing physical injury to roots. During outbreaks, the damage caused by Lepispilus sulcicollis manifests in thinning of crop stands, which requires immediate agronomic intervention. Damaged plants become significantly more susceptible to secondary fungal and bacterial infections.

Control measures include both agrotechnical and chemical strategies. Key management practices include crop rotation, deep autumn plowing, weed control, and maintaining optimal soil moisture levels. If the economic threshold of damage is exceeded, applications of systemic or contact insecticides registered for use in open or protected ground are recommended.
