International Journal of Tropical Insect Science, 1987
Systems of different technological levels have been developed for the mass-rearing of cassava mealybugs, Phenacoccus manihoti, cassava green mites, Mononychellus tanajoa and their natural enemies. Prototypes have been built and are being evaluated for host plant growth, host insect and mite production and output of natural enemies.

The Cassava Mealybug,Phenacoccussp. in the Republic of Zaire
PANS, 1979Abstract The occurrence of the cassava mealybug Phenacoccus sp. in Zaire is reported. Data on its biology, particularly oviposition, female fecundity and nymphal development are presented. Most of the insects settle on the leaf midrib and secondary veins and the growing points of cassava. The first instar nymph (crawler) is vary important in the spread

Environmental Suitability of the Cassava Mealybug Assessments Using Ecological Niche Modelling
Applied Mechanics and Materials, 2014The cassava mealybug (Phenacoccus manihoti) is one of the main pests in the world and the risk of invasion posed by this pest is becoming more and more serious with regard to increasing areas of planting cassava in Asia. It is urgent to analyze the potential geography distribution of P. manihoti among cassava in China.
