Animated coloured scanning electron micrograph (SEM) of Chicken body louse antenna tip (Menacanthus stramineus). The tip of the antenna contains specialized sensory structures, mechanoreceptors and chemoreceptors. The setae or hairs are mechanosensory in function. while the pores are chemosensory in function. The chicken body louse occurs wherever poultry hosts can be found. This chewing louse feeds on skin fragments, feathers and debris and causes the host's skin to be irritated, red, and scabby. As a result, infested birds lose weight and layers decrease egg production. Extremely heavy infestations can kill poultry.
