Objective：To synthesize and screen the halonitrophenol compounds with highly insecticidal activity against ectoparasites and fascila hepatica. Methods ： Salicylal was used to synthesize the title compound 1 - 15 by nitration,halogenation and nucleiphilic-substitution reaction. The structures of these compounds were confirmed by elemental analysis, IR and 1^ HNMR spectroscopic evidence. The miticidal activities were tested in vitro. The insecticidal activity of some compounds were determined in mitochondrial respiration control ratio （RCR）. Results and Conclusion ：The compound 1 - 15 were new compounds. Most of them showed higher insecticidal activity, especially compound 2, 6, 8 and 13 also showed the activity against ectoparasites and fascila hepatica.
