The Northern fowl mite (Ornithonyssus sylviarum) is the most common external parasite found on poultry. It feeds on blood and can cause anemia if the poultry is heavily infested. The mite’s development from egg to egg-laying adult takes about one week under optimum conditions—cool months are more favorable than warm ones.

There are three pairs of setae on the sternal plate in Ornithonyssus bursa and only two pairs in Ornithonyssus sylviarum. Life Cycle This mite’s life cycle is similar to the northern fowl mite. It has five stages: egg, larva, protonymph, deutonymph O. sylviarum spends the majority of its life cycle on the host (Sikes and Chamberlain 1954), but it is often associated with nesting material when young birds are in the nest. With a short generation time of 5Ð7 d, O. sylviarum populations can build up rapidly, reaching upward of 22,000 individuals in a single nest Chamberlain 1954, Masan andOrszaghova 1995). Abstract Background: Northern fowl mites (Ornithonyssus sylviarum) are obligate hematophagous ectoparasites of both feral birds and poultry, particularly chicken layers and breeders.They complete their entire life-cycle on infested birds while feeding on blood. Infestations of O. sylviarum are difficult to control and resistance to some chemical classes of acaricides is a growing concern. Mites.

Newly infested birds can support populations exceeding 20,000 mites in 9-10 weeks. Mites can survive 2-3 weeks off the host.3 The northern fowl mite is the most common external poultry parasite. Left unchecked, One application of Elector PSP at recommended levels can break the life cycle and control northern fowl mites.2 In addition, Elector PSP poses no cross-resistance issues for producers who use pyrethroids, carbamates or organophosphates.

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 week under optimal conditions [2–4].

It feeds on blood and can cause anemia if the poultry is heavily infested. The mite’s development from egg to egg-laying adult takes about one week under optimum conditions—cool months are more favorable than warm ones.

Pathogenesis. The mite causes feathers to become matted and severe scabbing can develop. Scabs are particularly seen around the vent. The presence of the mite decreases egg production.

Ornithonyssus sylviarum mites, hen Scaly leg mite infestation The most economically important of the many external parasites of poultry are mites of the families Dermanyssidae and Macronyssidae (poultry red mite, northern fowl mite, and tropical fowl mite) and Trombiculidae (turkey chigger).

Artificial feeding of northern fowl mites, Ornithonyssus sylviarum (Canestrini and Fanzago) (Acari: Macronyssidae), through membranes. Northern fowl mites (Ornithonyssus sylviarum) are obligate hematophagous ectoparasites of both feral birds and poultry, particularly chicken layers and breeders. They complete their entire life-cycle on infested birds while feeding on blood. Ornithonyssus bursa is widespread, and has been found in both tropical and temperate regions, while Orn. sylviarum occurs in temperate climates. A few mites have been eradicated from domesticated animals in some countries.
