Investigation of presence, distribution, and adult insects flight period of some species of clearwing moths Synanthedon spp. (Lep.: Sesiidae) using pherpmone traps in Sanandaj city

The family of Sesiidae includes about 1400 species in 150 genera. The larvae of these insects feed on the cambium of the tree and dry the tree. Using pheromone trap is one of the suitable methods for monitoring the pest in orchards. Therefore, in this study, the presence and distribution of clearwing moth were examined in the province, in 7 locations with an average distance of 20 km from each other in the city of Sanandaj using 6 pheromone traps in each region. Also in order to study the activity of the adult insects of different species of the mentioned insects in every 3 garden areas 6 traps (pheromone capsule containing two species Synanthedon myopaeformis (Borkhausen) (Lep.: Sesiidae) and Synanthedon tipuliformis (Clerck) (Lep.: Sesiidae)) were deployed that they were continuously (every 3 days) visited. The results showed that Synanthedon tabaniformis (Rott.) (Lep.: Sesiidae) species is present in all regions of trapping and the highest density of this pest is related to Qeshlagh dam garden (43 moths per  trap) (p< 0.05) and the S. tipuliformis species was observed in none of the trapping areas; also species of S. myopaeformis was observed in 3 regions at low concentrations. Studying the emergence period of S. tabaniformis adult insects showed that the first moths were trapped in the region of Qeshlagh dam garden in 2014/6/6, in the region of Salawat Abad in 2014/6/10, and in the region of Grize in 2014/6/13. The peak of the flight was observed in the two regions of Qeshlagh dam garden and Grize in 2014/6/23 and in the region of Salawat Abad in 2014/6/20. Finally, the last moths were trapped in the region of Grize in 2014/7/25, in the region of Salawat Abad in 2014/7/18 and in the region of Qeshlagh dam garden in 2014/7/21.
