Two potential ways that northern fowl mites, Ornithonyssus sylviarum (Canestrini and Fanzago), initiate infestations in poultry flocks were investigated: between-farm collection of eggs and transfer of egg flats, and the transfer of mites via eggs from breeder flocks to pullet growing operations.

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.

However, there is a lack of information on the effects of NFM on hen physiology, physical condition, and egg quality.

Diatomaceous earth and kaolin failed to reduce ectoparasites on non-user hens, and ectoparasites on user hens recovered after dustbox removal. A sulphur dustbox eliminated mites from all hens (including non-users) within 2-4 weeks.

Ornithonyssus sylviarum, otherwise known as the northern fowl mite, is a common ectoparasite of chicken flocks worldwide. They are a very small mite, ranging in size from 0.5-1 mm (0.02-0.04 in). NFM permanently live their entire lives on their host, spending most of their time on the feathers, traveling to the skin surface to feed on blood.

[8] showed that reduced levels of lysine in the diet of chickens decreased the intensity of the inflammatory response, and lowered resistance of birds to northern fowl mites (Ornithonyssus sylviarum). This work indicated that limited nutritional resources can impair immune function and ectoparasite resistance. Abstract.
