Within the framework of a project for the integrated management of cassava pests, the International Institute of Tropical Agriculture is investigating options for the control of the cassava green mite Mononychellus tanajoa. One potential control agent is the entomophthoralean fungus, Neozygites floridana; Brazilian isolates have been imported for release in Africa as a classical biological control agent.  N. floridana does not grow in vitro and required a special means of releasing it in the field. An in vivo approach was developed for this purpose where the pathogen in its living hosts was released in the fields. Mites were infected in the laboratory with N. floridana and living-infected mites were released. Mite populations were monitored before and after the release to evaluate the establishment of the pathogen.
