Green-striped bush-cricket

Systematic position. The green-striped bush-cricket (Poecilimon ornatus) belongs to the order Orthoptera and the family Tettigoniidae. This insect is a notable species within the bush-cricket group, often inhabiting meadows, shrubs, and agricultural landscapes where it finds abundant food sources.

Crops damaged. This species is a polyphagous pest that poses a threat to various cultivated plants. It frequently attacks vineyards, orchards, vegetables, and field crops such as sunflowers. The insect is particularly destructive when it feeds on young, tender tissues of leaves and emerging shoots.

Biology and life cycle. The life cycle consists of the egg, nymph, and adult stages. Eggs are deposited in plant tissues or cracks in the bark. Nymphs emerge in the spring and undergo several molts before reaching adulthood. Throughout their development, they remain highly active feeders, particularly during warmer daylight hours.

Nature of damage and harmfulness. The damage caused by these insects includes ragged leaf margins, holes in foliage, and destruction of buds or flowers. Heavy infestations can lead to significant biomass reduction, poor plant growth, and ultimately a decrease in the quality and quantity of the agricultural harvest.

Protection measures. Effective control involves both preventive and corrective actions. Keeping fields clear of weeds is essential to reduce potential habitats. When populations exceed economic thresholds, the application of targeted insecticides is necessary to prevent extensive damage. Integrated pest management practices are recommended.

• Regular inspection of crops during the vegetative period.
• Management of weeds to reduce host availability.
• Application of approved insecticides to manage large populations.
