Efficacy of different pheromone trap design in monitoring of the box tree moth, Cydalima perspectalis in the northern forests of Iran

Abstract The box tree moth, Cydalima perspectalis, is the most important pest of the box tree in the world. The use of pheromone is expected to reduce use of chemical pesticides in C. perspectalis. In this study, the efficiency of three different types of traps including funnel, wing and delta traps at two installation heights (2 and 4 m above the ground) and also dynamic activity of C. perspectalis at different elevations above sea level was investigated in Mazandaran province (Iran) in 2018 and 2019 seasons. The results showed that funnel traps in comparison with the other two types of traps (delta and wing) captured significantly more C. perspectalis. However, trap height had no effect on trapping. C. perspectalis was active in the box reservoir at different elevations above sea level
