Lutte biologique contre la cochenille du manioc

The loss of a basic food supply for Africa to an exotic insect, the cassava mealybug, can be overcome through classical biological control. In the area of origin in Latin America, natural enemies (parasitoids and predators) are being searched. After basic ecological studies and quarantine processing they are shipped to Africa. Detailed studies on the biology, ecology, and behaviour of the cassava mealybug have been undertaken and are also being carried out for the newly discovered natural enemies. New methods of mealybug mass rearing for natural enemies production are being tested as well as efficient methods for the releases of the promising natural enemy species. For follow-up studies on the effectiveness of these natural enemies, life tables and key factor analyses are used. A proper economic analysis of the project may provide interesting figures about the economic benefits obtained from biological control. (EN)
