In the present study, experiments were conducted to investigate fumigant toxicity of the essential oil from Myrtus sp plants for adult Aconthocelides obtectus, Sitophilus oryzea and Rhizoperta dominica in vitro conditions. The essential oils were isolated with the water distillation method by Neo-Clevenger apparatus. During the study 10% (v/v) doses of oils in 20 cc of compressed rubber-capped glass tubes were used. After 24 hours mortality rates of the essential oil were compared. Myrtus sp essential oil showed the highest fumigant toxicity on A. obtectus (46.66%). The lowest fumigant toxicity on S. oryzea (8.88%). The contact toxicity plant extracts (Prangos ferulacea, Alkanna orientalis, Myrtus communis) were tested against S. oryzea under laboratory conditions. Single dose contact toxicity effects of plant extracts were tested on S. oryzea adults via applying 1 mu l extract suspension (10% w/v) to individual insect. The greatest contact toxicity to S. oryzea adults was observed with M. communis (43.33%) and A. orientalis (41.11%) extracts. P. ferulacea (34.44%) extracts produced moderate toxicity to S. oryzea adults.
