In the light of using of 5‐imidazolinones in agriculture as safe and stable herbicides, the pesticide activities of some new synthesized derivatives 3‐18 of this ring system against “cotton leaf worm ( Spodoptera littoralis )” have been investigated. The interpretation of the elemental and spectral analyses proved the correct structural formulae of the new synthesized compounds. The compounds 1 , 5 , 6a , b , 8a , c , 9 , 11 , 12 , 15 , 16 , 17 , and 18 showed higher potency than chlorpyrifos ( dursban ) recommended insecticide. While the derivatives 2 , 3 , 4 , 7 , 8b , 10 , 13 , and 14 showed toxicity values less than chlorpyrifos insecticide. The 5‐imidazolinones 9 and 12 may be potentially used as insecticides for treatment of cotton leaf worm.
