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 vulgaris
L. (Lamiaceae), Achillea millefolium L., Artemisia absinthium L. (Asteraceae) and Hypericum perforatum L.
(Hypericaceae), were evaluated under laboratory conditions using two test methods (topical application and
spraying) on adult stage of the European Sunn pest, Eurygaster maura L. (Hemiptera: Scutelleridae), one of the
most important cereal pests. The experiments were conducted in conditions at 26±1°C, 60±10% RH and 16/8 hours
light/dark. Percent mortalities were recorded 24, 48 and 96 h after treatment. The results from the both assays
showed that all of the plant extracts tested had a toxic effect in varying degrees. After 96 h, F. vulgare extract was
the 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 the
results suggest that the plant extracts tested, especially F. vulgare extract, have a potential in the control adults of
E. maura.
