Meadow grasshopper

The meadow grasshopper (Euthystira brachyptera) is a member of the Acrididae family within the order Orthoptera. This species is easily identified by its short wings, which are typically reduced and do not fully cover the abdomen, especially in females. Their coloration usually mimics the green or brownish hues of the grasses they inhabit.

This pest primarily infests cereal crops, forage grasses, and meadow vegetation. It thrives in humid environments such as damp grasslands, field edges, and overgrown pathways. By feeding on leaves and stems, these insects can cause significant reduction in biomass and weaken plant vitality in agricultural fields.

The life cycle of this species consists of an egg stage, several nymphal instars, and the adult phase. Eggs are laid in the soil during late summer and remain in diapause throughout the winter. Hatching occurs in spring, and the nymphs undergo progressive development before reaching maturity in the mid-summer months.

Damage occurs through the direct consumption of foliage. In cases of high population density, these grasshoppers can defoliate significant patches of crops, hindering photosynthesis and crop growth. The damage is most critical during the early developmental stages of cereal plants, which are sensitive to leaf loss.

Effective pest management strategies are essential for crop protection. Recommended actions include:

• Tillage practices to expose and destroy egg pods in the soil.
• Maintenance of field margins by mowing to eliminate natural habitats for nymphs.
• Application of selective insecticides when the threshold of damage is reached.
• Field scouting to identify early signs of infestation and prevent population spikes.
