Analysis of Biological Control of Cassava Pests in Africa. II. Cassava Mealybug Phenacoccus manihoti
The Journal of Applied Ecology, 1988 (1) The effects of the cassava mealybug, Phenacoccus manihoti Mat.-Ferr., on cassava, Manihot esculenta Crantz, growth, development and yields as modified by weather, soil water and nitrogen, and natural enemies were examined. (2) Rainfall-induced mortality and plant carbohydrate stress were the major determinants of P.

Biological Characteristics of the Cassava Mealybug Phenacoccus Manihoti (Hemiptera: Pseudococcidae)
Revista Colombiana de Entomología, 2014 The cassava mealybug Phenacoccus manihoti (Hemiptera: Pseudococcidae) feeds by sucking the sap of cassava plants, causing damage directly by sucking the sap and contaminating the plant with its toxic saliva and indirectly by favoring the development of sooty molds.

Effects of Nitrogen and Calcium on the Level of Resistance of Cassava to the Mealybug P. Manihoti
International Journal of Tropical Insect Science, 1994 The effects of various levels of cow manure (equivalent to 0–50 kg nitrogen/ha.) or ground limestone (equivalent to 0–5 tons calcium/ha.) on the expression of resistance of cassava, Manihot esculenta Crantz to the cassava mealybug, Phenacoccus manihoti Mat. Ferr., were investigated under semi-controlled conditions in the laboratory.
