Pheromone and light traps are useful agents for monitoring and control of box tree moth (Cydalima perspectalis; Lep., Crambidae)

Box tree moth Cydalima perspectalis (Walker, 1859) is one of the most important monophagous pests. This pest feeds on the leaves and bark of the Box trees' stems, causing the death of the trees in some cases. For pest monitoring in 2017, 160 Delta pheromone traps were and to investigate the possibility of pest control by pheromone traps in 2018, 600 funnel pheromone traps were installed in the 450-hectare boxwood forest of Cheshmeh - Bulbul (Bandar-e-Gaz, Golestan Province). Also, two light traps and four pheromone-light sticky traps with photocell lamps were installed in the studied area. The results showed three flight peaks for the box tree moth and the best time for chemical control and use of the pheromone traps were determined. Our results also indicated the effectiveness of funnel-pheromone traps in reducing the damage to box tree moths. A significant difference between the number of boxwood moths trapped in pheromones with and without pheromones (P-value <0.05) was obvious; thus, combining light traps with pheromones increases their efficiency.
