Noyes, J.S. 1984 A new genus and species of encyrtid (Hymenoptera: Chalcidoidea) parasitic on the cassava mealybug, Phenacoccus manihoti Matile-Ferrero (Hemiptera: Pseudococcidae).. Bulletin of Entomological Research 74(3): 529-533.

Notes: Parapyrus manihoti gen. et sp. n., an encyrtid parasite of Phenacoccus manihoti Matile-Ferrero on cassava in Paraguay, is described from the adults of both sexes. The parasite is of potential use as a controlling agent of this mealybug in West and Central Africa where it is established as a pest of cassava.
