The investigation of fumigant effects of essential oils of the thymus sipyleus (Boiss.) subsp. rosulans (Borbas) jalas (Lamiaceae) and mentha longifolia subsp. longifolia (Lamiaceae) against some pests of stored products

In this study was investigated fumigant effects on adult of important pests of stored products of Rhizopertha dominica (Fabricius, 1792), Oryzaephilus surinamensis (Linnaeus, 1758), Cryptolestes ferrugineus (Stephens, 1831), Callosobruchus maculatus (Fabricius, 1775) and Tribolium confusum Jacquelin du Val, 1861 of obtained essential oils above ground of Thymus sipyleus (Boiss) subsp. rosulans (Borbas) Jalas and Mentha longifolia (Hudson) subsp. longifolia in the Lamiaceae family of plants collected from 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 Thymus sipyleus subsp. rosulans and Mentha longifolia subsp. longifolia species changed depending on the type of insect and plant, the concentration applied and time after application and the highest effect was obtained from M. longifolia subsp. longifolia.
