Voracity of Hyperaspis raynevali (Col.: Coccinellidae) - a predator of cassava mealybug, Phenacoccus manihoti (Hom.: Pseudococcidae).
Hyperaspis raynevali was reared with Phenacoccus manihoti and Planococcus citri in a laboratory experiment, to study its feeding behaviour and capacity. The nutritional quality of P. manihoti was slightly better than that of P. citri as long as poinsettia [Euphorbia pulcherrima] was not used to culture the mealybug. P. citri was a useful prey to rear H. raynevali easily for use as a biological control agent against P. manihoti.
