Abstract
In this research, toxicities of methanol extracts from the eight plants; Cuminum cyminum L.,Foeniculum vulgare Miller, Pimpinella anisum L. (Umbelliferae), Lavandula angustifolia Miller, Thymus vulgarisL. (Lamiaceae), Achillea millefolium L., Artemisia absinthium L. (Asteraceae) and Hypericum perforatum L.(Hypericaceae), were evaluated under laboratory conditions using two test methods (topical application andspraying) on adult stage of the European Sunn pest, Eurygaster maura L. (Hemiptera: Scutelleridae), one of themost important cereal pests. The experiments were conducted in conditions at 26±1°C, 60±10% RH and 16/8 hourslight/dark. Percent mortalities were recorded 24, 48 and 96 h after treatment. The results from the both assaysshowed that all of the plant extracts tested had a toxic effect in varying degrees. After 96 h, F. vulgare extract wasthe most toxic extract in both tests. After 48 h, the ranking of extracts with regard to toxic effects (LC50 values)obtained from the both assays was as follows; F. vulgare > L. angustifolia > C. cyminum > A. millefolium > P.anisum > A. absinthium > T. vulgaris > H. perforatum at the topical, and F. vulgare > C. cyminum > T. vulgaris >H. perforatum > L. angustifolia > A. absinthium > P. anisum > A. millefolium at the spraying assays. Over all theresults suggest that the plant extracts tested, especially F. vulgare extract, have a potential in the control adults ofE. maura.
