dc.description.abstractA study was undertaken to determine the ef cacy of cypermethrin in Haemaphysalis intermedia ticks from smallholder ocks in Namakkal district and organised farms of Veterinary College and Research Institute (VC&RI) and Mecheri Sheep Research Station (MSRS). Bioassays viz., Adult Immersion Test (AIT) and Larval Packet Test (LPT) were used in this study. A signicant reduction in egg mass was observed at higher concentration of cypermethrin. AIT showed that the LC50 and LC95 values were 103.39 ppm and 291.11 pm with 95 per cent con dence interval for ticks from smallholder  ock and 106.15 ppm and 310.92 ppm with 95 per cent con dence interval for ticks from VC&RI farm. LPT revealed that LC50 and LC95 values of larvae from smallholder  ock, VC&RI and MSRS farms were 97.76 and 284.20, 97.57 and 280.41, and 98.38 and 274.37 respectively with 95 per cent con dence interval. High mortality with low reproductive index among the survived ticks and low discriminating doses indicated that H. intermedia ticks were susceptible to cypermethrin.en_US
