Abstract
The leopard moth, Zeuzera pyrina L. (Lep: Zeuzeridae) is an important polyphagous pest of a wide range of trees and shrubs across Europe and Asia. The efficient control of the leopard moth by direct spraying of infested branches and trees is usually impractical because the larvae feed internally and escape from exposure to the used insecticides. Sexual pheromones emitted by females may provide an efficient alternative method to explore the pest, disrupt its mating or capture and kill it. In the present study, we evaluated the efficiency of one Iranian-formulated (in three doses: 1, 1.5, and 2 mg per trap) and three non-Iranian-formulated sexual pheromones in attraction and capturing of adult males of the leopard moth in Walnut orchards of Alborz province and three different regions of Kerman province (Rabor, Baft, Darremorid). We found a wide diversity in response of adult males to different pheromones in the four studied regions. This diversity seems to be resulted from isolation of the populations and may present a preliminary stage of divergence and speciation in this species.

Keywords Zeuzera pyrina;adult male;sexual pheromones;traps;walnut orchards.
