The non-hematophagous mites of the Megninia genus (Suborder Astigmata, Family Anaigidae) are included in this group.
In the industrial layer hens, the species of the genus Megninia are important and responsible ectoparasites for damages in the eggs' production, being also told in other hosts, as parakeets, turkeys and pigeons (GUIMARAES et al.
Considering the economic, productive and sanitaries damages for the commercial laying hens industry can be attributed to the ectoparasitism by Megninia spp.
A database was built with information from 402 chicken houses of 42 commercial properties from the state of Minas Gerais to evaluate some epidemiological aspects that could characterize the presence of Megninia spp.
2%, Goniodes gigas 1% y Chelopistes meleagridis 1%, una especie de garrapata Argas persicus 2% y el acaro Megninia cubitalis 12%.
2%); Goniodes gigas (1%) and Chelopistes melagridis (1%) one species of fowl tick: Argas persicus (2%), and one species of mite: Megninia cubitalis (12%).
Mayaudon y Montoya  reportaron la presencia de Megninia cubitalis en plumas de gallinas.
En el estudio realizado en 100 gallinas de corral (Gallus gallus domesticus), procedentes del Municipio San Francisco del estado Zulia, se aislaron y determinaron 12 especies de ectoparasitos, de los cuales 10 fueron piojos: Goniocotes gigas, Menopon gallinae, Menacanthus stramineus, Lipeurus caponis, Goniocotes gallinae, Gonoides dissimilis, Goniodes sp, Goniodes gigas, Colpocephalum sp, Chelopistes meleagridis; una especie de garrapata: Argas persicus y el acaro: Megninia cubitalis.
Other mites may be observed in the layer hens, although they are most often found in subsistence breedings such as the species of the Genus Megninia (Acari: Analgidae) (Megnin, 1877), which has few reports in industrial chickens (TUCCI et al.
6% of inspected laying farms were infested by Megninia ginglymura (Megnin, 1877).
In Brazil there are no studies regarding effectiveness of chemicals on the control of Megninia spp.
2003) reported the use of Neem oil at 2 to 3%, for control of mites of genus Megninia in Cuba, obtaining strategic control success.
