Potato as a valuable agricultural product has some injurious pests. In a research, we compared the important aphids abundance in two parts of Iran. Collection of aphids was carried out by yellow water trap and aphid/leaf count methods every week in ¬2015-2016. We selected seed potato fields with five distances (0, 100, 200, 400, 500m) from viral plant resources in Hamadan and Isfahan, Iran. The results showed in Hamadan Aphis gossypii Glover had the most/lowest numbers (3.40 and 0.17 at distances (0) and (200) m) however, in Isfahan were 10.00 and 0.00 aphid at distances (200) with (500) m, correspondingly. The furthest population for Myzus persicae (Sulzer) was found at (0) distance in Isfahan. There was no significant difference between the parts aspect of photosynthesis and Leaching tests on potato. Geographical indices may influence on aphids and pay attention to field distances is important to control aphids in the first step on crop management.
