Typing of ticks among 28 infested cattle revealed that Boophilus annulatus was responsible for cattle infestation in a fann in Beni suef. Ivomec injection evidenced curicity percentage of 100% after one week for adult ticks and 81.9% for nymphs. This percentage decreased to 98.6 % for adult ticks and increased to 95.8 % in nymphs at the end of the experiment (5 weeks post treatment). Neem oil curicity percentage after one week for adult ticks was 95.6 %, 98.4 % and 100 % at dilutions 1.6. 3.2 And 6.4 % respectively and for nymphs was 96.8 %. 95.1 % and 100% at the three dilutions respectively from the second week until the end of the experiment (5 weeks) for adult and nymph except the curicity % at the third week post treatment at dilution 6.4% was decreased to 99.8% which considered exception for the whole recorded results and may be due to re-infestation or wrong in application of drug on the animals. Increasing of concentration of Neem oil increased curicity percentage of adult ticks and nymphs after one week of treatment and that revealed in recorded results 95.6%. 98.4% and 100 % at dilution of 1.6, 3.2 and 6.4% respectively for adult and 96, 8, 95.1 and 100% at dilutions of 1.6, 3.2 and 6.4% for nymph respectively. The results revealed that Neem oil was more effective and of longer duration than that of Ivermectin 1 % until the end of the experiment.
