A new library of 1,3,4-thiadiazole-containing pyrazole oximes was designed and synthesized. Their acaricidal and insecticidal activities were evaluated. Bioassay results indicated that some target compounds exhibited good acaricidal and insecticidal properties. Especially, compound 8m had 80% acaricidal activity against Tetranychus cinnabarinus at the concentration of 50?μg/mL, compound 8f displayed 100% insecticidal activities against Aphis craccivora at the concentration of 50?μg/mL, compounds 8r and 8w showed 100% insecticidal activities against Plutella xylostella at the concentration of 50?μg/mL. Furthermore, compounds 8r (LC50?=?19.61?μg/mL) and 8w (LC50?=?9.78?μg/mL) possessed comparable or even better insecticidal activities than the control Pyridalyl (LC50?=?17.40?μg/mL) against P. xylostella.

In this study, in order to find novel biologically active pyrazole oxime compounds, a number of dichloro-allyloxy-phenol-containing pyrazole oximes were designed and synthesized according to the method of active group combination. All of the target compounds were confirmed by 1H-NMR, 13C-NMR and elemental analysis. In addition, bioassays showed that all of the newly synthesized compounds had no acaricidal activity against Tetranychus cinnabarinus and low insecticidal activity against Aphis craccivora at tested concentrations. However, most of them displayed excellent insecticidal activity against Oriental armyworm at a concentration of 500 μg/mL, and some designed compounds still exhibited potent insecticidal activity against Oriental armyworm even at the dose of 20 μg/mL, especially compounds 7f, 7n and 7p had 100%, 90% and 90% inhibition rates, respectively, which were comparable to that of the control pyridalyl.

A series of new pyrazole oximes bearing substituted thiazole ring were designed and prepared. The structures of the title compounds were identified by spectral analyses. The results of primary bioassay indicated that some targeted compounds exhibited promising insecticidal activity besides acaricidal activity, particularly; compounds 8c and 8d were more potent against Tetranychus cinnabarinus and Plutella xylostella than other analogues.
