Abstract

This work reports the phytochemical profile and insecticidal properties of Perovskia artemisioides Boiss essential oil (PAEO) collected in Baluchestan, Iran. Totally, twenty-six substances were identified with 1,8-cineole (25.81%), geranyl acetate (13.00%) and linalool (10.21%) as dominant chemical metabolites by GC-MS analysis. PAEO possessed fumigant toxicity against various growth stages of Phthorimaea operculella. P. operculella adults showed considerable sensitivity (LC50 = 0.58 µL/L air) in comparison to eggs (LC50 = 5.87 µL/L air) and neonate larvae (LC50 = 1.23 µL/L air). Finally, molecular docking of major components of PAEO was performed against detoxification enzymes, including cytochrome P450 and glutathione S-transferase activities. Humulene, β-caryophyllene, and α-cadinol exhibited the most interactions with the P450 and GST. It can be concluded that PAEO has the potential for development into natural insecticides for the control of storage pests.
