Steppe grasshopper

The steppe grasshopper (Euchorthippus pulvinatus) is a member of the order Orthoptera and the family Acrididae. As a common inhabitant of grassland ecosystems, this species can occasionally reach high densities, becoming a significant pest in agricultural environments when ecological conditions favor its development.

This insect primarily targets cereal crops, including wheat, barley, oats, rye, and various millets. In addition to cultivated grains, it thrives on native grasses and pastures, posing a risk to livestock productivity by consuming large quantities of forage biomass during peak infestation years.

The biology of the steppe grasshopper follows a univoltine life cycle, meaning one generation per year. The species overwinters in the egg stage within egg pods deposited in the soil. Larvae emerge during the spring and undergo several nymphal stages before reaching the adult phase by early summer.

The damage caused by these grasshoppers involves the consumption of leaf blades, typically starting from the leaf edges. Excessive feeding can lead to complete defoliation, which severely restricts the plant's ability to photosynthesize, resulting in stunted growth and a considerable decrease in grain yield.

Effective management strategies for controlling the steppe grasshopper involve a combination of preventive and reactive measures. Cultural practices, such as tillage after the harvest, are crucial for destroying soil-dwelling eggs. Chemical control using authorized insecticides is recommended when larval populations exceed economic threshold levels.
