Two hundred and ninety four engorged female ticks were collected from 4 different geographical regions for assessment of tick resistance against acaricide compounds. The 15-21 day- old larvae have been tested in accordance with FAO recommended larvae packet test. Resistant factor for each region was calculated by LC50 and LC99. Minimum LC50 [0.008] and, Maximum LC50 [0.024] for Amitraz were seen in arid and northern regions with resistant factor equal 3. Minimum LC50 [0.001] and, Maximum LC50 [0.003] for Cypermehtrin were seen in mountainous and southern costal regions with resistant factor equal 3. Minimum LC50 [0.003] and Maximum Lc50 [0.014] for Diazinon were seen in the northern and arid regions with resistant factor equal 4.7. In comparison with Probit test results; the applied concentrations denote Amitraz and Cypermethrin at recommended concentration do not slay 100% of the larvae in the northern and arid region. However Diazinon can slay all the larvae even at concentrations lower than the recommended doses
