This study was carried out in order to investigate the insecticidal effects of Satureja hortensis L., S. montana L., S. spicigera L. and S. thymbra L. (Lamiaceae) against alfalfa weevil (Hypera postica (Gyllenhal, 1813) (Coleoptera: Curculionidae)) causing economic damages in alfalfa fields of Çalpala village belonging to center in Igdir province under laboratory conditions (25±1°C, 60±5% RH and 14:10 L:D) between the years of 2016 and 2017. To test the toxicities of these essential oils on alfalfa weevil, H. postica adults, 15 adult individuals were placed to Petri dishes (9 × 1.5 cm deep) and each dose essential oil (5, 10 and 20 µL/petri) was sprayed on adults. After that, enough amounts fresh alfalfa leaves of Medicago sativa L. were added for feeding of the adult insects. Petri dishes were wrapped with parafilm paper by covering with a lid. The sterile water+etanol as control and Malathion, a commercial insecticide as positive control were used. All the tests were made in triplicate. At 24th, 48th, 72nd and 96th hrs of the treatment, mortalities of the adults were recorded. The mortality rates were established to be variable ranging from 4.44 to 100%. While the highest mortality rates (from 48.8% to 100%) were determined in the 20 µL/petri dose of S. hortensis essential oil, the lowest mortality rates (between 4.44% and 62.20%) were in the 5 µL/petri dose of S. spicera essential oil. According to the results, it was determined that S. hortensis and S. thymbra essential oils have higher mortality effect, but S. montana and S. spicigera essential oils have lower effect. It has been determined that the tested essential oils have insecticidal activity on the insects of the alfalfa horticulture and can be used in the fight against this harmful insecticide.
