The investigation of fumigant effects of essential oils of Salvia L. (lamiaceae) species against some pests of stored products

In this study was investigated fumigant effects on adult of important pests of stored products of Rhyzopertha dominica (Fabricius, 1792), Oryzaephilus surinamensis (Linnaeus, 1758), Cryptolestes ferrugineus (Stephens, 1831) Tribolium confusum Jacquelin du Val, 1861 ve Callosobruchus maculatus (Fabricius, 1775) of obtained essential oils above ground of Salvia hydrangea DC. ex Bentham, Salvia verticillata L. subsp. amasiaca (Freyn. & Bornm.) Bornm. and Salvia nemorosa L. from Lamiaceae family of plants collected in Iğdır province. The obtained essential oils of these plants were prepared in 3 replications at 5, 10 and 15 μl / petri doses under 25 ± 1ºC temperature and 65 ± 5% relative humidity conditions. LC50 and LC90 values were determined by looking at the mortality rates at 12, 24, 48, 72 and 96 hours at different times. As a result of the studies, the toxicity levels of essential oils obtained from Salvia species changed depending on the type of insect and plant, the concentration applied and time after application and the highest effect was obtained from S. hydrangea.
