The present work aimed to evaluate the insecticidal activity of Cymbopogon citratus essential oil and its major compounds (citral myrcene) on Anticarsia gemmatalis. oil, citral, myrcene, a mixture citral myrcene were tested at concentrations 0.1, 0.3, 0.5, 0.7, 0.9 % v/v, plus two negative controls (distilled water Tween-80® 0.5 v/v) positive control (novaluron 0.075 w/v). Insect mortality was evaluated in 24, 48, 72, 96 h. According results, C. citral-myrcene v/v effective A. gemmatalis, with 88 mortality, respectively, first 24 At this concentration, caused 100 after 72 h, whereas had no effect caterpillars even h exposure. Thus, can be potential option for alternative
