Abstract
The presence of Aleurocanthusspiniferusis reported in Apulia from April 2008. This polyphagous whitefly is now spreading northward and invading new territories.This paper refers about recently occupied areas detailing local and urban outbreaks and population density per host plant species.We use digital camera-equipped stereoscope and Cryo-SEM on the laboratory and direct observation on the field.We note the presence of A. Spiniferus in Puglia region and we depict the invasion of agricultural and urban areas.The overall behaviour and ecological preferences of the alien pest are discussed in view of its available means of control.
