| Popis: | The present study was carried out at September 2010 to evaluated tick infestation of cattle in Al-Najaf province with diagnosis of cypermethrin resistance by using FAO larval packet test and modified larval packet test. The result showed that the infestation rate of acariasis was 54.34%. The identification of ticks revealed that 55.06% of collected ticks were Hayaloma spp., while the percentage of Boophilus spp. and Rhipicephalus spp. Were 31.86% and 13.08% respectively. According to site of infestation, the highest percentage was recorded in udder 45%, followed by perineal region 25%, head –neck 18% and others 7%. The LPT results showed there was no significant variation (P≤0.01) between the mortality rates of Boophilus (96.42%) and Hyaloma (96.72%) at recommended dose. In other hand, the MLPT method showed that the mortality rate of Boophilus larvae at recommended and double recommended doses were 94.82% and 98.04% respectively, while all the Hyaloma larvae were killed at the recommended dose. |
