Taxonomic placing: Insecta, Hemimetabola, Hemiptera, Sternorrhyncha, Aleyrodidae.

Common name: Olive whitefly.

Geographic Distribution: Mediterranean region, Iran, China.

Morphology: Puparium flattened, black, with fine setae around body. Adults whitish, covered with a white powdery wax.

Host plants: Oleaceae, like olive and Phillyrea spp. and Murraya sp. (Rutaceae).

Life history:- This species has 1-2 annual generations, being active in summer and autumn, each female depositing 50-60 eggs on the upper leaf surfaces.

Economic importance: A minor, occasional pest of olives. Its feeding on the leaves causes some damage but most injury is due to the excreted honeydew that is colonized by sootymold.
