Abstract

The alien mealybug Phenacoccus defectus Ferris (Rhynchota Pseudococcidae) is recorded in Italy for the first time. The species was first starting from 2009 on potted plants of Aeonium arboreum, Echeveria sp., Sedum palmeri, Sempervivum tectorum (Crassulaceae) and Senecio citriformis (Asteraceae). Comments on the morphologically very similar Phenacoccus solani Ferris and Phenacoccus solenopsis Tinsley are discussed.
