Аннотація: Plants` essential oils play a considerable role in the plant integrated protection systems against harmful insects. Therefore the aim of our study was to find the potential repellency and toxicity effects of essential oils (EOs) from Allium sativum L., Ocimum basilicum L., Lavandula angustifolia Mill, Eucalyptus globulus, Labill and Curcuma longa L., and two chemical substances DEET (N, N-diethyl-3-methylbenzamide) and 2-Undecanone on the black cherry aphids Myzus cerasi. 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 and mortality was evaluated after 2, 6 and 24 hours for insecticidal activity test. The repellent index was most influenced by the concentration of essential oil; the percentage of influence was 64%. At the same time, the highest repellency index 95% was achieved at a concentration of 1.5% when using essential oils of A. sativum and E. globulus, as well as when using 2-Undecanone within 30 minutes of waiting. A contact toxicity (mortality) test in Petri dishes showed efficacy for all tested oils and chemicals after a 6-hour treatment period. The lowest concentration that ensured 100% insect mortality was 0.9% when using E. globulus essential oil. The lowest lethal concentration (LC50) value of 0.00240 mL/10 mL was obtained with O. basilicum oil and the lowest LC98 value of 0.28209 mL/10 mL was obtained with E. globulus oil after a 6-hour treatment period.
