Abstract To search for novel 2-arylpyrroles with unique biological activities, a series of novel 2-arylpyrrole derivatives were designed and synthesized, and their structures were characterized by 1 H and 13 C NMR spectroscopy, MS spectrometry, and elemental analysis. Their insecticidal activities against Lepidopteran pests (eg Mythimna separata) and acaricidal activities against mites (eg Tetranychus urticae) were evaluated. The results of ...
