Ornithonyssus sylviarum From Wikipedia, the free encyclopedia Ornithonyssus sylviarum (also known as the northern fowl mite) is a haematophagous ectoparasite of poultry. In both size and appearance, it resembles the red mite, Dermanyssus gallinae.

Hen housing (cage or cage-free) did not impact overall abundances of northern fowl mites, Ornithonyssus sylviarum (Canestrini & Fanzago) (Acari: Macronyssidae), or chicken body lice, Menacanthus stramineus (Nitzsch) (Phthiraptera: Menoponidae). Cage-free hens received a dustbox with sand plus diatomaceous earth (DE), kaolin clay or The two Ornithonyssus species reported to infect hamsters are Ornithonyssus bacoti, the tropical rat mite or red mite, and Ornithonyssus sylviarum, the northern fowl mite. Although O. bacoti has a wide host range, the primary hosts are the brown Norway rat ( Rattus norvegicus ) and the black roof rat ( Rattus rattus ) ( Fox, 1982 ). 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. Las larvas tienen tres pares de patas; las ninfas y adultos tienen cuatro pares. Los adultos miden de 0.6 a 1mm de largo y son escasamente visibles a simple vista, a menos que se estén moviendo.

Deltamethrin, Ornithonyssus sylviarum Background Two major ectoparasite species severely affect the poultry industry worldwide: the northern fowl mite, Ornithonyssus sylviarum, and the poultry red mite, Dermanyssus gallinae [1, 2]. Both mite species are obligate hematophagous parasites able to complete their life-cycles within about one The northern fowl mite (Ornithonyssus sylviarum, NFM) (Canestrini and Fanzago, 1877) is a blood-feeding ectoparasite of birds that is a common pest of the poultry industry in North America . Infestations by NFM on laying hens reach high densities (>70,000 mites/bird), which result in host blood loss, tissue inflammation and costly reductions in productivity [ 1 , 2 ].

The mites remain on the fowls throughout the day and may be seen on the plumage.
