Northern fowl mite population development on laying hens caged at three colony sizes. 1983

F H Arthur, and R C Axtell

Beginning 5 weeks after being experimentally infested with known numbers of northern fowl mites, Ornithonyssus sylviarum (Canestrini and Fanzago), White Leghorn pullets caged alone supported a significantly higher mite population than did pullets housed two and three per cage. During the following 6 weeks, mite populations remained high on the birds caged singly whereas mite populations drastically declined on the birds housed two or three per cage. Eleven weeks after the experiment was initiated, all hens caged alone were infested with northern fowl mites, whereas 22% of the birds housed two per cage and 43% of the birds housed three per cage were free of mites. These data support the hypothesis that social stress in birds influences the development of northern fowl mites (more stress, higher resistance to mites).

D008924	Mite Infestations	Infestations with arthropods of the subclass ACARI, superorder Acariformes.	Acariasis,Mange,Infestation, Mite,Infestations, Mite,Mite Infestation
D008925	Mites	Any arthropod of the subclass ACARI except the TICKS. They are minute animals related to the spiders, usually having transparent or semitransparent bodies. They may be parasitic on humans and domestic animals, producing various irritations of the skin (MITE INFESTATIONS). Many mite species are important to human and veterinary medicine as both parasite and vector. Mites also infest plants.	Acarus,Mite
