Effects of certain acaricides on the mortality rates of argas [persicargas] persicus [Ixodoidea: argasidae]

The obtained results show that Argas [P.] persicus ticks are more susceptible to organophosphate acaricides, Diazinon and Malathion than the organochlorine, Neguvon. Susceptibility of adults to Diazinon was higher than Malathion. The nymphs were affected similarly, while larval stage showed the highest susceptibility to these acaricides. All stages of A. persicus ticks showed high resistance to Neguvon. The survival periods of treated ticks were 1 to 7 days, and 1 to 10 days when treated by Diazinon or Malathion, and Neguvon respectively. It is concluded that usage of organophosphate acaricides is more economic to control the fowl ticks, and that control should be at intervals no longer than one week
