Resistance of Hard Tick （Ixodidae） with some Acaricide in Cattle （Naturally Infestation） in Sulaimani Governorate Fields-Kurdistan Regional/Iraq

A study carried out for assessment of acaricide for control and how to show resistance of hard tick （Ixodidae） with some types of acaricide which available in Sulaimani marked froro February to April 2012, isolated 80 cattle （local breed） naturally infested with hard tick. Six hundred and fifteen ticks min7 tick/cattle including three genera species were collected and identified, the highest Boophilus spp. followed by Hyalomma spp., and Rhipicephalus spp. were less frequent species collected. Experimental cattle divided into four groups each group content 20 cattle, treatment with four types acaricide and their average of infestation in cattle with Boophilus spp. 33 （41.25%） as the commonest, followed by Hyalomma spp. 31 （75.38%）, Rhipicephalus spp. 11 （13.75%） and 5 （6.25%） found mixed infested with Boophilus spp. and Hyalomma spp. 65 （81.3%） of cattle samples had emaciation and skin lesions. According to site of infestation, it showed that inguinal region was the most common predilection site for the ticks. Observed the genera Boophilus spp., there were highly significant differences （12.52%） between different tick species when calculated by general test （LSD）. The objective of this study was to estimate and compare these acaricide to control hard tick, and there was highly significant relation between different species of hard ticks when treated by these acaricide, according to the chi-square tests. The activities of the acaricide through the time of application were different on the tick genera species. Diazinon （60%） and carbamate （saven 85%） has been a greater degree than other acaricide resistance, while shows the activity of both acaricide injectable ivermactin and cypromethrein through the early time on all species. The results of the study otherwise provide encouraging possibilities for the potential use recommended dose with both acaricide ivermactin-l% and cypromethrine-10%.
