The repellent effect of enriched neem oil, Azadirachta indica A. Juss, was tested on adults of Schistocerca gregaria Forskal. For this purpose enriched neem oil was applied at the rate of 10 l/ha to one of the two plants of Schouwia thebaica WEBB (Brassicaceae). After the application, 120 adults were released into the cage. The second plant, in the same cage, remained untreated. S. gregaria consumed 100 % of the leaves of the untreated S. thebaica. 244 hours after the application and after that untreated plant was consumed, the adults start feeding on the treated plant. In a second repellent trial, 120 adults were transfered into a cage where only a treated plant of S. thebaica was present without an alternative of untreated plant. 98 locusts that means more than 80 % of the initial population size died within 10 days. On the 11th day the rest of adults start feeding on the treated plant.
