dc.descriptionThe cassava green mite Mononychellus tanajoa (Bondar), accidentally introduced from South America into Africa, has spread across the cassava belt and is causing severe yield losses to cassava. Biological control was recognized as the most promising and sustainable strategy against this pest. Among the different stages of a biological control program, mass rearing of beneficials is often a major bottleneck. The different rearing systems used by the International Institute of Tropical Agriculture are described. A mother culture system maintains pure and high quality colonies and provides inoculum to start mass production. Twenty biotypes are maintained separately and no contamination has been found in the cultures. Oligophagous species are reared in the insectary on artificial substrate, using alternative prey as a food source. For phytoseiid species specific to M. tanajoa, an “on plant” system is used in a greenhouse. Advantages and disadvantages of the two different systems are discussed as well as general requirements and constraints in rearing phytoseiids.
