Host information from Logvinenko 1976, Drosopoulos 1976, Booij 1982, Drosopoulos 1983, Wilson et al. 1994, Nickel 2003, Holzinger et al. 2003. See Also FLOW for hosts I may have missed.

Predators and parasites
Charletonia cardinalis (c. l. koch, 1837) (C. L. Koch, 1837) (Acari, Trombidiformes, Erythraeidae) on Muellerianella brevipennis;  Stroinski et al. (2013: 197).

Economic importance

Muellerianella fairmairei is a vector of Northern cereal mosaic virus (NCMV).


In North America, there is only a single described species.  It is a robust species, with a dorsal stripe and dark frons, flecked with pale. All species in the genus have an expanded ‘anal angle’ of the male pygofer, and tend to have black flattened parameres.
