Description
Summary:•Essential oil yield was similar for both hydrodistillation techniques.•More oxygenated compounds were obtained by microwave-assisted hydrodistillation.•All the essential oils reduced the longevity and fecundity of Myzus persicae adults.•Mentha pulegium essential oils at 500μl/l were the most effective against M. persicae.•The bioactivity of the essential oils is associated with their main constituents. The essential oils derived from three plants within the Lamiaceae family, Origanum majorana L. (marjoram), Mentha pulegium L. (pennyroyal), and Melissa officinalis L. (lemon balm), using two techniques for their isolation, were evaluated for their effects on longevity and fecundity of the aphid Myzus persicae (Sulzer). The two techniques employed were Clevenger hydrodistillation (i) using conventional heating (HD) and (ii) assisted by microwaves (MWHD). Analysis of the essential oils by GC-MS showed an increase in the oxygenated fraction determined in MWHD oils. The effects of essential oils were screened with two concentrations, 250 and 500μl/l, on aphid adults
