其他摘要：Hyalomma anatolicum ticks are multi-host ticks responsible for various direct and indirect losses on animals and is also related to spread of zoonotic disease virus i.e. CCHF virus. Control of ticks is totally dependent on repetitive use of chemical compounds leading to development of resistance or inefficacy of drugs. A study was conducted to assess the efficacy of commercial preparation of Amitraz in H. anatolicum ticks of North Gujarat by two step stratified random sampling procedure from areas having complain of treatment failure by using Amitraz. Larval Packet Test (LPT) was conducted using field strain for determination of 50 and 95% lethal concentration of Amitraz. Results obtained from the test showed inefficacy of Amitraz in tick isolates from Vasda tick isolate (LC 50- 18340 ; LC 95- 1769636) and Palanpur tick isolate(LC 50- 8949.6; LC 95- 2640503) which are much higher than market recommended dose rate. The data on field status of efficacy of amitraz from the area with diversified animal genetic resources will be helpful to implement suitable strategy to overcome the process of development of resistance in ticks.KEY WORD: Amitraz, Hyalomma anatolicum, Larval Packet test, Acaricidal activity.
