Abstract : Investigations on the distribution and biology (including food plants and natural enemies) of Rastrococcus invadens in Africa are reviewed, including some previously unpublished material. The parasitoid Gyranusoidea tebygi was introduced into Togo in November 1987 and released as a biological control agent against the mealybug on mangoes and Citrus. Establishment, spread and effectiveness of the encyrtid were very good, resulting in satisfactory control.
