Abstract: The present manuscript covers the insecticidal bioefficacy of some new synthesized amides of salicylic acid viz; N-(phenyl)-2 hydroxy salicylimide, N-( p-tolyl) -2-hydroxy salicylimide, N- (p-chlorophenyl)-2 hdroxysalicylimide, N- (P-methoxy Phenyl-2 hydroxy salicylimide and N- ( p- chlorophenyle) -2 hydroxy salicylimide on seeds of chickpea, Cicer arietinum L.ver. K- 805 were treated with different concentration (0.06%, 0.12%, 0.25%, 0.50% and 1.00%) levels against the attack of chickpea bruchid Callosobruchus chinensis Linn. (Coleoptera : Bruchidae). These compounds are found effective in in controlling the insect infestation in chickpea under storage condition.In the present paper we describe the insecticidal activity of these amides against early emerged adults of C.chinensis L. of both male and female, respectively. Successful adoption of new synthesized amides of salicylic acid in the protection of food commodities promises an eco-friendly option compatible with international bio-safety regulations. The newly synthesized amides such as C13H11NO2 > C13H10NO2Cl > C13H10NO2Br > C14H13NO2 > C14H13NO3 insecticidal compound exhibited lethal concentration LC50 values in following respective descending as 0.34 >2.01 >2.12 >2.97 3.53, respectively It was found that the compounds show moderate efficacy against the insect.
