 abstract={The insecticidal and antifeedant activity of extracts derived from different plants of the Liguidamber orientalis Mill. (Hamamelidaceae), Tanacetum vulgare L. (Compositae), Achillea coarctata Willd. (Compositae), Buxus sempervirens L. (Buxaceae), Diospyros kaki L. (Ebenaceae), Arum italicum Mill. (Araceae), Achilea biebersteinii Willd. (Compositae), Origanum vulgare L. (Labiatae), Hypericum androsaemum L. (Hypericaceae) and Ocimum basilicum L. (Labiatae). are reported. The 70% alcohol extracts of plants were tested for toxicity against the 3–4th instar larvae of the Yponomeuta malinellus Zell. (Lepidoptera.: Yponomeutidae). Antifeedant activity of the extracts was assessed through tests conducted on the larvae of Y. malinellus by the feeding protection bioassay. In tests carried out on the larvae of Y. malinellus, L. orientalis, O. basilicum and A. coarctata extracts showed high toxicity within 48 hour LC50’s of 75, 75 and 65% respectively. The toxicity effects of the other extracts were determined as 60, 50, 50, 50, 45, 45 and 40% within the same period, respectively. No mortality was noticed in control groups. Alcohol extract from L. orientalis, T. vulgare and B. sempervirens showed high antifeedant activity (80.90, 46.12) on the larvae of Y. malinellus. In addition to both T. vulgare and L. orientalis extracts caused decrease consumption of food per 1 mg of larvae body weight decrease showed high –8.465, –0.845, mg respectively. The highest consumption (557.6 mg) was observed with alcohol extract from, D. kaki whereas the minimum one was using alcohol extract from L. orientali. The other tested extracts showed similar activity.},
