• Biology: Occurring on the roots of the host plant. Often found in considerable numbers attended by the ant Tapinoma melanocephalum (F.).
• Economic Importance: Stahl (1927) and Stahl & Scaramuzza (1929) have described the damage caused in Cuba, when areas of sugar-cane died out due to heavy population of the mealybug on the roots.
• General Remarks: Good description and illustration of the adult female given by Morrison (1926), Williams (1970DJ) and by Williams & Granara de Willink (1992).
