Siphoninus finitimus Silvestri (Hemiptera: Aleyrodidae), "mosquita blanca del olivo" en Arica-Chile

In this note are given background on the morphometric differences, in the genitalia of adults and the puparium of aleyrodidae populations associated with olive, pear and pomegranate in the region of Arica-Parinacota, Chile. The signifcant differences (p < 0.01) found in the dimension, and in the morphology of the structures studied between the different populations of whitelfy that attack to olive trees with regard to the pear and the pomegranate allow to establish that in Arica the whitefy of the olive tree is Siphoninus fnitimus Silvestri and that S. phillyreae, it is associated with pear and pomegranate.
