چکیده

Two hundred and ninty 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.
