In Morocco, the sugar beet crop is severely harmed by the insect pest Cassida vittata Vill. which affects its yield quantity and quality. Chemical pesticides are considered the most common strategy to control this pest, and their use is extremely harmful to human health and the environment. In this context, the adults of C. vittata were exposed to five essential oils (EOs) obtained from Artemisia herba alba Asso. (Asteraceae), Eucalyptus globulus Labill. (Myrtaceae), Mentha pulegium L. (Lamiaceae), Rosmarinus officinalis L. (Lamiaceae), and Shinus terebinthifolius Raddi. (Anacardiaciae). Their contact and fumigant activity was evaluated every 24 h for 3 days. Their repellent effect was tested by filter paper and sugar beet discs every 5 min for 30 min. Their antifeedant effect, via the nutritional indices RGR, RCR, ECI and FDI, was evaluated using three doses in each experiment. For the contact toxicity, M. pulegium, A. herba alba and R. officinalis showed the highest mortality rates with 100%, 92% and 78%, respectively, after 24 h at 0.283 µl · cm -2. For the fumigant toxicity, 100% mortality was observed at the highest concentration of M. pulegium after 24 h and from A. herba alba with 88% and 96% after 48h and 72h, respectively. Regarding the repellent effect by filter paper, the repellency of R. officinalis and A. herba alba was 82, 92% and 57, 85%, respectively. However, M. pulegium showed 63% of repellency after 5 min at 0.057 µl · cm-2. In the antifeedant test, M. pulegium gave significant results in all nutritional indices. In conclusion, M. pulegium was the most effective in all tests used in this study. Our findings promote the use of these essential oils as efficient biocontrol compounds against the adults of C. vittata.
