Abstract:In order to further study the acaricidal activities of HNPC-A14344/14343, the acaricidal activities of HNPC-A14344/14343 against the Tetranychus cinnabarinus(Boisduval) were tested by the Potter nebulization method. The results of bioassay indicated that HNPC-A14344 showed excellent activity against the Tetranychus cinnabarinus (Boisduval) at the value of LC50 5.78 mg·L-1, which was superior to that of spirotetramat, a LC50 value of 8.65 mg·L-1, and a little better than that of Spirodiclofen, a LC50 value of 6.05 mg·L-1. Furthermore, the activity of HNPC-A14344 against the Tetranychus cinnabarinus(Boisduval) is obviously superior to that of HNPC-A14343. HNPC-A14344 was valuable for further research and development.
