Ravinia

Robineau-Desvoidy, 1863

Species Guides

Ravinia is a of flesh flies (Diptera: Sarcophagidae) established by Robineau-Desvoidy in 1863. within this genus exhibit diverse strategies: some are of other dipteran larvae in cattle , while others have forensic importance. Larvae of at least one species, Ravinia lherminieri, demonstrate strong resistance to through haemocytic . The genus has been recorded in North America, Europe (Denmark, Norway, Sweden), and Brazil.

Habitat

Associated with bovine and cattle environments; laboratory studies confirm larval development in such substrates.

Distribution

North America (Vermont, United States); Europe (Denmark, Norway, Sweden); South America (Brazil, including state of Bahia).

Host Associations

Musca autumnalis - preyFace fly and larvae are preyed upon by Ravinia lherminieri larvae in laboratory conditions; 98% mortality achieved at :prey ratios of 10:200
Heterotylenchus autumnalis - experimental /unsuitable host generally fails to develop in Ravinia lherminieri due to strong resistance via haemocytic

Behavior

Ravinia lherminieri larvae exhibit -dependent on face fly immatures, with mortality decreasing from 98% to 0% as volume per larva increases from 10 ml to 80 ml. Larvae can survive on bovine feces alone but show 26% higher survival when prey is available. Strong cellular immune response to includes haemocytic , tracheolar proliferation, and novel melanization of the larval anal organ.

Ecological Role

agent of face fly (Musca autumnalis) in cattle ; potential natural enemy for . Some have forensic importance.
