Assessing Flight Propensity of the Box Tree Moth, Cydalima perspectalis using Flight Mill Methodology

Box tree moth (Cydalima perspectalis, Walker) is an invasive species present in Croatia since 2012 where causes great damage to plants of the genus Buxus. The pest spreads rapidly, has high reproductive potential and good adaptability. Its known natural dispersal velocity is up to10 km per year. Understanding flight characteristics of insect pests is essential for designing effective strategies and programs for their management. The aim of this study was to assess flight propensity of C. perspectalis and to evaluate its invasive character using flight mill technology. C. perspectalis flew a maximum distance of 15.6 km (virgin females) and spent a maximum time in flight of 241 minutes (4 hours). The average speed of C. perspectalis ranged from 1.1 m/s to 1.6 m/s. Knowledge of C. perspectalis wing characteristics and flight performances are of great importance in assessing dispersal and provide important insights into migratory activities.
