The pea leaf weevil, Sitona lineatusL. (Coleoptera: Curculionidae, PLW), is a significant insect pest of pea (Pisum sativumL.) and faba bean (Vicia fabaL.), and it is responsible for serious economic damages. The current study aims to investigate the insecticidal activities of seven essential oil species on S. lineatusadults in the laboratory as well as the most effective ones under growth chamber conditions. Out of the tested essential oils, Lavandula angustifoliaMill. and Mentha arvensisL. oils showed substantial insecticidal activity against S. lineatusadults (100%) by contact activity at a concentration of 1.5% after 1 and 3 h of application, respectively, with an estimated LC50of 0.224 and 0.320% at 72 h after treatment, respectively. L. angustifoliaessential oil also resulted in a significant mortality rate of 70% by ingestion activity, with an LC50of 1.340% at 48 h after application under laboratory condition. The growth chamber bioassays confirmed these significant effects, displaying a mortality rate of 70% at 96 h after application at 1.5%. The gas chromatography–mass spectrometry analysis showed that linalool acetate (32.91%) and linalool (26.69%) dominated the L. angustifoliaessential oil composition. These findings highlighted that L. angustifoliaessential oils are promising agents for the development of biopesticide formulation for the control of S. lineatus, as a safe and ecofriendly alternative compared to chemical insecticides. |
