The development, viability, and life cycle parameters of Dermanyssus gallinae at five different temperatures (15, 20, 25, 30 and 35 degrees C), and at relative humidity 70-85% were evaluated. Life cycle duration was 690.75 h (28 days) at 15 degrees C, 263.12h (11 days) at 20 degrees C, 164.63 h (7 days) at 25 degrees C, 140.69 h (6 days) at 30 degrees C and 172.04 h (7 days) at 35 degrees C. The optimal development temperature for D. gallinae was 30 degrees C, with the greatest survival in all stages and the shortest development time. High mortality at 35 degrees C indicated that this temperature had adverse effects on development of D. gallinae, and that in field conditions D. gallinae populations may decrease or even disappear due to the negative impact of high temperature on development. There were no significant differences in the pre-oviposition period among the four temperatures 20-35 degrees C, indicating that temperature did not affect this part of the life cycle.
评估了鸡皮刺螨在5种不同温度（15、20、25、30和35摄氏度）以及相对湿度70 - 85%条件下的发育、活力和生命周期参数。生命周期时长在15摄氏度时为690.75小时（28天），20摄氏度时为263.12小时（11天），25摄氏度时为164.63小时（7天），30摄氏度时为140.69小时（6天），35摄氏度时为172.04小时（7天）。鸡皮刺螨的最佳发育温度为30摄氏度，在此温度下各阶段存活率最高且发育时间最短。35摄氏度时死亡率较高，表明该温度对鸡皮刺螨的发育有不利影响，在野外条件下，高温对发育的负面影响可能导致鸡皮刺螨种群数量减少甚至消失。20 - 35摄氏度这四个温度下的产卵前期没有显著差异，表明温度不影响生命周期的这一阶段。
