<p></p> <p>A series of novel <i>N</i>-pyridylpyrazolecarboxamides containing benzothiazole were designed and synthesized. The target compounds were identified by <sup>1</sup>H NMR,<sup>13</sup>C-NMR, IR, high-resolution mass spectrum (HRMS) and elemental analysis. The bioactivities of the new compounds against oriental army worm (<i>Mythimnaseparata</i>) and diamond back moth <i>(Plutellaxylostella</i>) were evaluated. The results of bioassays indicated that some of the compounds showed good activitiesat the tested concentrations. Compound <b>Ij</b> showed 100% larvicidal activities against <i>Plutellaxylostella</i> at 2.5 mg/L, while the activity of <b>Ij</b> against <i>Mythimnaseparata</i> was 100% at 10 mg/L.</p
