Siphoninus phillyreae

Definition

A species of whitefly (family Aleyrodidae, order Hemiptera), commonly called the ash whitefly, native to western Eurasia, India, and North Africa and introduced to North America. It is a polyphagous pest of fruit and ornamental trees, with documented hosts including pomegranate, pear, apple, ash (Fraxinus), and ornamental pear (Pyrus calleryana). The species has become a target for classical biological control, notably using the parasitoid wasp Encarsia inaron.

Etymology

Example

Siphoninus phillyreae infestations on pomegranate orchards in California prompted successful biological control programs using Encarsia inaron in the 1990s.

Usage Notes

Often referenced in integrated pest management literature for its invasion history and successful parasitoid-mediated suppression. The specific epithet phillyreae refers to its association with Phillyrea (olive family), though its host range is considerably broader.
