摘要：

Cecidochares connexa is currently the only effective biological control agent of Chrotnolaena odorata an invasive weed in West Africa. Recently, an ectoparasitoid species belonging to the Ormyrus genus was found parasitizing C. connexa in three regions of Ghana. Adult parasitoid emergence percentages varied between 16 and 21%. This raises concerns about its impact on C. connexa populations and the overall biocontrol of C. odorata. New field surveys to determine the distribution range of Ormyrus sp. and its impact on C. connexa should be quickly addressed in West Africa.
