Evaluation of insecticidal activity of some benzofused heterocycles against different insect pests
754-762The 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.),<i style="mso-bidi-font-style:
normal"> 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.
