The fumigant activity of essential oil vapours distilled from lavender (Lavandula angustifolia), mint (Mentha spicata), coriander (Coriandrum sativum) and sage (Salvia officinalis) were tested against eggs (0-24 hours-old) and larvae (20-25 days-old) of mediterranean flour moth, Ephestia kuehniella under 22+2 C and 27+ 2 C conditions.The essential oils were tested to the pest with three replicates that each contain 20 eggs or larvae. Exposure times were 24, 48 and 72 hours.
Fumigant toxicity was changed according to temperature, oils, biological stage of the pest, dose and exposure time. It was found that the sensitivities of the larvae and the eggs to the essential oils were different at the base of LC50. While the eggs were more sensitive than the larvae against to the lavender oil, but it was same in mint oil and it was more resistant to the coriander and sage oils.
At the end of the tests against to the larvae and the eggs for 72 hours exposure time; the lavender and mint oil showed lower toxicity (over 90% mortality with 175 l/l – 300 l/l air) ) than the other two oils. At 272C lavender essential oil toxicity apperently decreased for the eggs and the larvae, but the toxicities of the mint and coriander oils were not evidently affected from the temperature change. Sage oil toxicity was higher to the eggs at the 27+ 2 C
