Abstract
In order to search for novel potent and environmentally benign insecticides, a series of anthranilic diamides containing various fluorinated groups were designed and synthesized. Their structures were confirmed by 1H NMR, 13C NMR, 19F NMR, elemental analysis, HRMS or mass spectra. Their insecticidal activities against oriental armyworm (Mythimna separata) and diamondback moth (Plutella xylostella) were evaluated. The preliminary structure-activity relationship (SAR) was discussed in detail. The biological assay indicated that most of the compounds exhibited moderate to excellent insecticidal activities. Especially, Ia showed high larvicidal activity against oriental armyworm. Meanwhile, Iu had better larvicidal effects against diamondback moth than commercial chlorantraniliprole.
