(2003): Labiate essential oils affecting host selection and acceptance of Thrips tabaci Lindeman

Abstract:
Essential oils from plants within the Lamiaceae family at several concentrations were evaluated for their repellent and deterrent properties against Thrips tabaci Lindeman (Thysanoptera: Thripidae), the onion thrips. Rosemary (Rosmarinus officinalis L.) essential oil repelled onion thrips females at 10% concentration in olfactometer bioassays. In leaf disc bioassays on leek (Allium porrum L.), 1% concentration of rosemary oil inhibited settling within a 4-h period. In dual-choice experiments marjoram (Origanum majorana L.) and mint (Mentha arvensis L.) oil both at 0.1% and 1% concentrations significantly deterred the egg-laying activity of thrips females on treated leaf discs. Lavender (Lavandifla angustifolia L.) oil at 1% and sage (Salvia officinalis L.) oil at 0.1% concentration affected oviposition. In no-choice assays, thrips oviposition rate was significantly reduced by about 45-60% compared to the untreated control after application of marjoram and lavender oil at 1% or 0.1% concentration. With mint oil, oviposition deterrence was found only at 1% concentration. Repellent and/or deterrent essential oils combined with other control measures against T tabaci may contribute to the enhancement of biological or integrated pest management strategies.
