Summary: The aim of the study was to find the potential repellency of Curcuma longa L. essential oil (EO) and two chemical substances DEET, (N, N-diethyl-3-methylbenzamide) and 2-Undecanone on Aphis pomi DeGeer., Dysaphis plantaginea Passerini and Myzus cerasi F. Repellent peculiarities were evaluated at five different concentrations – 0.3%, 0.6%, 0.9%, 1.2% and 1.5%, with 4 replications at the interim of 15 and 30 minutes for an olfactometer test. Results showed that repellency was increased with increasing the concentration and expecting time. The results showed that the volatiles from C. longa at 30 minutes, significantly repellent to aphids in an olfactometer. The strong repellent activity was recorded on Aphis pomi (2.25 pcs.). We concluded that the EOs may have potential as an alternative to chemical control, and therefore, they could be included into integrated pest management of aphids, in the Europe and all over the world.
