In: Agricultural Research Journal, Suez Canal University 2011 v.11(2)Summary: Laboratory experiments were conducted under controlled conditions to test the insecticidal activity of aqueous and organic extracts of six plants collected from North-Sinia (Tree Tobacco, Nicotianaglauca G; Syrian Rue, Peganumharmala; Calotrpis, Calotrpisprocera; Chinaberry, Meliaazedarach L; Egyptianhenbane, Hyoscyamusmuticus and Artemisia monosperma) against 4th instar larvae of Cotton leaf worm, Spodopteralittoralis (Boisd).After extraction with Methyl alcohol and Ethyl alcohol, in case of using Methyl alcohol in extraction, the results showed that the aqueous extract of Hyoscyamusmuticus was the highest pesticidal activity then the other aqueous extracts with LDso equal to 0.066 xlOsppm. Also the organic extract ofHyoscyamusmuticus has the lowest LDso value and equal to 0.0112 xl OS ppm. Also in case of 2-nd part of experiment,
