ABSTRACT/SUMMARY: The relative toxicities of ten acaricides to northern fowl mite, Ornithonyssus sylviarum (Canestrini and Fanzago), and the chicken mite, Dermanyssus gallinae (De Geer), were determined simultaneously by holding the mites inside disposable glass Pasteur pipettes previously immersed in acetone solutions of various concentrations (w/v) of technical grade acaricides.

They are easily observed and are a reddish brown color. Ornithonyssus sylviarum. Darkened feathers due to a heavy infestation in the vent area of a laying hen. The entire life cycle of the northern fowl mite is completed on the bird. The mites are irritating to people and sometimes cause dermatitis in egg handlers and farm workers.

The nymphs and adults have piercing mouthparts and seek blood meals. The complete life cycle from egg to egg-laying adult can take from five to seven days or longer, depending on the environment. The mites are believed to feed on skin and secretions. The entire life cycle (10-17 days for human-infesting scabies mites) is spent on their host. Without a host, they survive only a few days.
