Abstract

The European red mite, Panonychus ulmi (Acari: Tetranychidae) is one of the main pests of apple trees worldwide. The main purpose of this research was to study the repellent and lethal effect of Heracleum persicum Desf. and Trachyspermum ammi L. essential oils (EOS) on the European red mite. The EOS of H. persicum and T. ammi were extracted using a Clevenger device and by water distillation method. The mortality of the mites was evaluated after 24 hours and the lethality of each EO was calculated in contact and fumigant toxicity in an incubator at 26 ± 2 °C temperature, 16:8 h L:D, and 50 ± 5% RH. It was found that the LC50 values of EOS of H. persicum and T. ammi were 343.91 and 311.74 µL l-1 for contact toxicity, and 2.54 and 2.85 µL l-1 air for fumigant toxicity, respectively. With increasing the concentration of EOS, the death rate of mites was increased. Three different concentrations of the EOS from H. persicum and T. ammi were tested for their repellent effects on the European red mite. Results of the present study revealed, that the repellency rate increased with increasing concentration, meanwhile, the T. ammi EO had the highest repellency among the concentrations.
