Short-winged conehead

The short-winged conehead (Conocephalus dorsalis) is a species of insect belonging to the order Orthoptera and the family Tettigoniidae. While often considered a typical inhabitant of wetlands and meadows, it can occasionally impact agricultural environments. As an herbivorous insect, it thrives in environments with high humidity and dense vegetation.

This pest mainly feeds on various cereal crops and grasses, including wheat, barley, and oats. Both nymphs and adults consume foliage, creating ragged edges or small holes in the leaf blades. While localized damage is common, significant population density spikes can occur, leading to more substantial foliage loss in the affected fields.

The life cycle involves an incomplete metamorphosis. Eggs are laid inside the stems of plants or within the soil, utilizing the female’s specialized ovipositor. The species typically overwinters in the egg stage. After hatching, nymphs go through several developmental instars, feeding greedily on plant tissues throughout the spring and summer months.

The economic impact of this species is linked to the reduction of the photosynthetic leaf area of the host plants. Heavy infestation can weaken young crops, making them less resilient to environmental stress and disease. In agricultural settings, damage is usually concentrated on the edges of fields bordering natural grasslands or marshy areas.

Effective management requires a combination of preventive and corrective measures. Maintaining clean field margins by removing excessive weeds and rank grasses reduces the insect's preferred habitat. If monitoring indicates that the population has reached economic thresholds, the application of targeted insecticides may be necessary to protect the crop during vulnerable growth stages.
