Oyarzun Iracheta, S.M., & González, R.H. 2005 Taxonomía, desarrollo y observaciones biológicas del chanchito blanco de los frutales, Pseudococcus viburni. [Taxonomy, development and biological observations of the fruit tree mealybug, Pseudococcus viburni (Signoret) (Hemiptera: Pseudococcidae)].. Revista Fruticola (Chile) 26(1): 5-12.

Notes: Pseudococcus viburni is an important insect pest of fruit trees and vineyards in Chile. Apart from feeding on phloem, additional damage is caused by the development of sooty moulds on secretions. However, the main economic concern is quarantine restrictions on exports to Mexico, Brazil and Peru. External and internal morphology is described to distinguish P. viburni from related species. Nymphs and adult females are characterized and a key is provided to the 3 nymphal stages. Notes on the life cycle and biology are included.
