Lice were collected from 71 flocks detected as infested at market inspection in 1990 and 1991, from 16 flocks where resistance was suspected and from 31 flocks from Kangaroo Island. Susceptibility to cypermethrin was measured by a treated surface technique and survival of lice at 5 ppm or greater was taken as an indication of resistance. The prevalence of resistance was 34% in louse populations from the market inspection sample, 50% in flocks in which resistance was suspected and 68% in flocks from Kangaroo Island. Most resistance factors were in the range 1 to 20 although one louse population with a resistance factor of 91 was found on Kangaroo Island.
1990年和1991年在市场检查中检测出受虱侵害的71个鸡群、16个疑似有抗药性的鸡群以及来自袋鼠岛的31个鸡群的虱子被采集。采用处理过的表面技术测定对氯氰菊酯的敏感性，虱子在5 ppm或更高浓度下的存活被视为抗药性的指标。在市场检查样本的虱种群中，抗药性流行率为34%，在疑似有抗药性的鸡群中为50%，在来自袋鼠岛的鸡群中为68%。大多数抗药因子在1至20的范围内，不过在袋鼠岛发现了一个抗药因子为91的虱种群。
