Long-tailed tree cricket

Systematic position: The species belongs to the order Orthoptera and the family Gryllidae (true crickets). Unlike many other crickets, this species has developed a specific oviposition strategy that categorizes it as a significant pest of various plant species.

Host plants: The pest primarily attacks woody and herbaceous plants. Common hosts include raspberry, blackberry, grapevines, various ornamental shrubs, and seedlings of fruit trees, where the stems provide a suitable substrate for egg deposition.

Biology and life cycle: Adults are typically slender with a light green or pale yellow coloration. The life cycle consists of egg, nymph, and adult stages. The overwintering stage is the egg, which is embedded inside the plant tissue by the female during the late summer or autumn period, remaining protected until hatching in spring.

Nature of damage and economic impact: The damage is caused by the female's ovipositor, which creates a series of punctures in the stems. This mechanical wounding disrupts the plant's vascular system, often causing the stem to break or wither above the site of the puncture. Furthermore, these wounds serve as entry points for pathogens, leading to secondary infections that reduce crop vitality.

Control measures: Cultural practices are the most effective management strategy. This includes the pruning and destruction of infested stems during the dormant season to eliminate overwintering eggs. In severe infestations, the application of registered insecticides during the early nymphal stage can be effective. Integrated pest management, focusing on monitoring and biological control, is recommended for sustainable production.
