ash whiteflies
Siphoninus is a genus of whiteflies in the family Aleyrodidae. The genus includes at least three recognized species: Siphoninus phillyreae (the ash whitefly), S. immaculatus, and S. gruveli. Siphoninus phillyreae is the most extensively studied species, known as a polyphagous pest with a broad global distribution spanning Europe, Asia, Africa, the Americas, and Oceania. The genus has been subject to recent taxonomic revision, including the revalidation of S. finitimus as a distinct species.
