Investigating seasonal massive population changes of Lobesia botrana Lep.: Tortricidae in Khondab (Arak) by using pheromone traps

Grapes is one of the most important garden products in the entire world, but in Iran is reduced quality and quantity by Lobesia botrana (Tortricidae: Lepidoptera(. natural products are suite for replacing chemical pesticides. One of this is pheromones for controlling this pest. This research has been done in 3 replicate, for studying efficiency pheromone traps to study seasonal population changes of L. botranaat three regions: Khondab (Hoseinabad, Jenga and Hesar), Enaj (Tourgir and Dehsad) and Khosbijan (Zalian). For this reason has been done sampling at different dates and places, with Delta yellow and white pheromone traps. The results showed the pest had 3 generation in all regions but there were different number of that Regards to climate. On the other side, both traps were affected on number of catches adults. So for controlling this pest in wild area of grapes, pheromone traps could be suggested in integrated pest management control programs.
