The chicken body louse, Menacanthus cornutus (Menoponidae s.l.) completes its whole life cycle on the body of Gallus gallus domesticus. The louse exploits the microclimate developed by host skin temperature and feather cover. The weekly visual examination has demonstrated the pronounced response on the population fluctuation of M. cornutus to the seasonal changes in the environment despite all favourable condition on the body of homothermic host. The experiments commences from April 2008. The peak index was obtained in the month of August followed by drastically decline in succeeding 5 months. Lice index begins building up slowly from the months of February and March. The correlation between mean monthly lice indices with temperature and photoperiod were analyses as strong positive. The moderate positive correlation was found with relative humidity and it remained insignificant with rainfall.
鸡体虱,角头禽虱(Menoponidae亚科)在原鸡(家鸡)体表完成其整个生命周期。这种虱子利用宿主皮肤温度和羽毛覆盖所形成的小气候。每周的目视检查表明,尽管恒温宿主体表具备所有有利条件,但角头禽虱种群数量波动对环境季节性变化仍有显著反应。实验于2008年4月开始。8月份获得峰值指数,随后在接下来的5个月里急剧下降。虱子指数从2月和3月开始缓慢上升。分析得出月平均虱子指数与温度和光周期之间呈强正相关。与相对湿度呈中度正相关,与降雨量的相关性不显著。
