Abstract: The twelve benzo-fused N,O,S-heterocyclic compounds have been investigated for biological activity against major pests of field crops, third instar larvae of Spodoptera litura (F.) and several stored product pests namely, Sitophilus zeamais (M.), Tribolium castaneum (H.) and Callosobruchus chinensis (L.). Responses show variation with test compounds, insect species, doses and exposure times individually. All the reported benzothiazines and benzoxines heterocycles have been prepared by eco-friendly method and characterized by IR, 13C and 1H NMR. The bioassay has been investigated with oviposition deterrency, LC50, chi-square and randomized block design. These results suggest that most of the compounds demonstrate potent insecticidal activity by feeding method (mortality 77-97%) in comparison to the contact and larvicidal activity.
