Abstract
The potato tuber moth Phthorimaea operculella is a serious pest of potato both in the field and storage that makes great problem in storage. Farmers routinely rely on chemical insecticides that could be hazardous for human health and environment. Insecticide resistance of P. operculella has been reported all over the world, so botanical origin materials may serve as proper alternative materials for controlling the pest. Natural products are generally preferred because of they are less harmful to non-target organisms, eco-friendly and biodegradable. In the present study, ovicidal activity of essential oils (EOs) of basil, European pennyroyal, lavender, mint, oregano and savoury and oviposition-deterrent activity of methanolic extracts of fumitory, lavender, licorice and oregano were investigated on P. operculella. Probit analysis showed that EOs of Lavandula angustifolia revealed the highest activity (LC50 value 0.4 μL/L air). Fumitory extract elicited the highest reduction in percentage of laying eggs. The results indicated that these medicinal plants could be effective for declining damage of P. operculella in storages.
