Abstract: 

Using water yellow traps, population fluctuation of winged aphids, vector of potatoes viral diseases, has studied in four districts of Hamedan province including Hamedan, Kaboodar ahang, Ghahavand and Assadabad during 1998-2000 period. In this connection, four species belonging to family Aphididae and one species of family Drepanosiphidae were collected. Among vector species Therioaphis trifolii forma maculata (Buckton) with 65-91% of total collected population tored other species in all above mentioned district. The other important species, collected in lower number, were Acyrthosiphon pisum (Harris), Myzus persicae (Sulzer), Macrosiphom euphorbiae (Thomas) and Aphis frangullae gossypii (Glover). Kaboodarahang with lowest population of aphid vectors and shortest period of aphid presence in potato fields considered as the most suitable region and Hamedan district owing to high vector population and longest presence of aphids in fields showed to be the most unsuitable site for basic seed potato production the other two districts are evaluated as intermediary to two above-mentioned regions.
