Survival and Demography of the Tomato Borer (Tuta absoluta) Exposed to Citrus Essential Oils and Major Compounds †

Tuta absoluta is a pest of importance: quick to disperse and difficult control due the cases resistance insecticide active ingredients. Thus, studies using essential oils (EOs) search for new molecules should be intensified. The objective present study was evaluate toxicity EOs from Citrus aurantifolia (lime), aurantium (petitgrain) bergamia (bergamot) its major compounds against T. in topical application test. Additionally, demographic parameters were studied after EOs. median lethal time (LT50) population 12h three tested. concentration (LC50) 33.75, 38.78 35.05 µg µL−1 C. aurantifolia, bergamia, respectively. As found gas chromatography coupled mass spectrometry (GC-MS) quantification, 44.74% EO α-terpineol, while 55.45% 58.12% respectively, linalyl acetate. tested at concentrations equivalent LC50 EOs, that is, 16.2 25.8 acetate, application. Both showed less than In sublethal effects tests, all negatively affected absoluta, with decrease duration larval instars, pupal period, fecundity, oviposition viability eggs, implying reduction growth this pest. lime, petitgrain bergamot are toxic low cause deleterious on reproductive absoluta.
