The present manuscript covers the laboratory stomach toxicity of new synthesized amides of C13H11NO2, C13H10NO2Cl, C13H10NO2Br, C14H13NO2 and C14H13NO3 on seeds of chickpea, Cicer arietinum L.ver. K 850 were treated with different concentrations (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 biosafety regulations.The newly synthesized amides compound exhibited lethal concentration and LC50 values in following respective descending order as: N- (phenyl) -2 hydroxy salicylimide (0.60) > N- (p- bromophenyle) -2 hydroxy salicylimide (0.68) > N- (p-tolyl) -2-hydroxy salicylimide (1.10) >N- (P-methoxy Phenyl-2 hydroxy salicylimide (1.20) > N-(p-chlorophenyle) -2 hydroxy salicylimide (2.97), respectively. It was found that all the compounds show moderate efficacy against the insect.
