The present study was conducted at the Institute of Agriculture in Karnobat, Bulgaria, in the period 2011-2014. After experiments on barley varietal susceptibility to certain herbicides it was determined that there were clear differences in the aphid population for each variant. It was reported that aphids prefer barley varieties treated with certain herbicides and doses. No aphids were found in barley varieties, not treated with herbicides. Dependence was established between the values of chlorophyll a+b and chlorophyll а / chlorophyll b and aphid attack. At higher values of these indexes the aphid attack was greater
