Abstract

Leopard moth, Zeuzera pyrina L. is one of the most important wood borers which causes heavy damage on walnut in different parts of Iran, especially in Chaharmahal va Bakhtiari province. In this research, efficiency of two pheromones (Synanthedon tipuliformis Clerkand Z. pyrina), two forms of pheromone traps (Delta and Funnel) and five installing height (4, 6, 8, 10 and 12 m above the ground), to catch male leopard moths were studied. Pheromone traps were installed in the walnut orchards at the second decade of May (before the adult emergence). Number of caught moth were recorded weekly and finally mean number of caught moths per trap were compared statistically among treatments. Results showed significant difference between pheromones and the pheromone of Z. pyrina was captured more number of the moths, whereas there was no significantly difference between traps (delta and funnel traps). Results of both years of the experiment showed installing height had a significant effect on the capturing of the male moths, and with increasing the height of installation, number of captured moths increased significantly. Mean number of caught moths per week were 1.38, 2.43, 7.77, 10.68 and 16.17 at the height of 4, 6, 8, 10 and 12 meters, respectively. In other words, the number of caught moths at the heights of 12 and 6 meters (above ground level) were11.6 and 6.59 folded of the 4 meter height, respectively. Based on the obtained results, trap form and installation height of the traps have significant effect on number of the caught leopard male moths by pheromone traps.
