Abstract: Potato, Solanum tuberosum L., (Solanaceae) is one of the essential basic food crops worldwide. It has been attacked by many insect pests, such as aphids Myzus persicae (Sulzer) (Hemiptera: Aphididae). This research amid to use plant essential oil elicitors to improve the controlling method of the green peach aphid M. persicae. In this study, different essential oils (EO) from medicinal plants were tested against M. persicae. Assessment of their potential role in inducing plant resistance pathways on potato „Sponta” cultivar was studied. Measuring two common enzymes indicators such as guaiacol Peroxidase (POX) and Polyphenol oxidase (PPO) expressed in plants post-physical or chemical injury. The Electrical Penetration Graph (EPG) was also used to monitor changes in aphid behaviors. The impact of the EO on aphid feeding behavior XXII was monitored and recorded for 8 hrs post-treatment. The effect of the medicinal plants' oil on the aphid mortality was carried out and measured in vitro Results showed that 60% of the essential oil extracts have insecticidal activity against M.persica. Results also revealed that some EO have significantly increased the level of POX or PPO, and insect behavior compared to the control. Mustard, Sage, Jojoba, Eucalyptus, Bitter cucumber, Camphor, and Rosemary oil have natural induction in potato. Camphor, Sage, Pomegranate, and Bittercucumber caused a disturbance in GPA settling behavior and prolong searching for a feeding site. Mustard, Eucalyptus, and Sage resulted in delaying drop potential associated with non-persistent and semi-persistent. Lavender, Eucalyptus, and Mustard caused a delay in sieve element behavior associated with persistent virus transmission.
