Firempong, S. 1981 A method of rearing the mealybug Planococcoides njalensis on cocoa seedlings.. Revista Theobroma 11: 229-232.

Notes: Reared mealybugs without the presence of their obligatory attendant ants; prevented honeydew from sticking to their bodies, thus eliminating the honeydew as the nutritional source of fungal attack that leads to the extinction of the mealybug colony.
