Abstract
AbstractChemical composition of Algerian Mentha rotundifolia and Myrtus communis essential oils, their insecticidal activities and their impact on some biological parameters of the Mediterranean flour moth Ephestia kuehniella were assessed. Results showed that M. rotundifolia essential oil contained piperitenone oxide (46.06%), d-limonene (9.10%), cis-piperitone oxide (6.81%), and endo-borneol (4.64%) as major compounds, while M. communis oil was rich in α-pinene (29.08%), 1,8-cineole (36.82%), α-terpineol (6.42%), geranyl acetate (4.38%), and β-linalool (4.04%). The fumigant potential and contact toxicity tests against E. kuehniella demonstrated the effectiveness of M. rotundifolia essential oil (LC50 = 0.54 μL/L air, LC50 = 0.004 μL/cm2) compared to M. communis oil (LC50 = 2.91 μL/L air, LC50 = 0.025 μL/cm2). Moreover, results revealed that all biological parameters were significantly affected (fecundity: 6 eggs/female, oviposition deterrence: 96.62%, log fertility: 0, hatching rate: 0%, copulation rate: 0% for M. rotundifolia oil against fecundity: 93 eggs/female, percentage of oviposition deterrence: 47.85%, log fertility: 6.7, hatching rate: 57%, copulation rate: 53.33% for M. communis oil). This work supports the use of botanical insecticide as active pest control agents under storage conditions.
