Short-tailed bush cricket

The short-tailed bush cricket (Barbitistes serricauda) belongs to the order Orthoptera and the family Tettigoniidae. This insect is characterized by its compact green body and a distinctive reddish-brown stripe along the back. The females possess a unique saw-like ovipositor, which they use to insert eggs into plant tissues.

This pest primarily attacks trees and shrubs, showing a clear preference for fruit-bearing species such as apple, pear, and various stone fruits. It is also known to feed on ornamental plants, causing significant aesthetic and structural damage to buds, flowers, and foliage during the spring and summer seasons.

The biological cycle consists of one generation per year. The species overwinters in the egg stage, with eggs deposited in the cracks of tree bark or under bud scales. In the spring, nymphs emerge and start feeding on fresh growth. Adults are typically seen from mid-summer, continuing their feeding cycle through the warm months.

The damage caused by these insects is quite visible, as they consume large amounts of leaf tissue, often leading to skeletonized leaves. When populations are high, they can defoliate entire branches, destroy fruit buds before they open, and scar young developing fruits, causing severe losses to the orchard's overall yield.

• Scrubbing rough bark during winter to remove overwintering egg clutches.
• Applying contact insecticides during the early nymphal stages in spring.
• Encouraging natural predators such as birds and beneficial insects in the garden.
• Monitoring the canopy closely during bud break to assess damage thresholds.

Effective management requires early intervention. Since the pests are often hidden among the foliage, thorough scouting is essential. Implementing integrated pest management strategies, focusing on early spring protection, is the most reliable way to maintain healthy trees and prevent economic damage from this bush cricket.
