Abstract
The population of aphid Rhopalosiphum padi (L.) was studied during the period 2006 – 2007 on oats varieties/lines (Dunav 1, Jubilei 4, Ruse 8, Resor 1, L 615 3, 354 2, 44 10, CR 146 – 11, CR 146 – 12 and Z 137-2-2) in Karnobat, Bulgaria. Aphid population appeared on all varieties/lines on 16 April and increased gradually up to 18 May 2007. The most resistant and most susceptible to aphid infestation varieties/breeding lines are investigated.
