Technical Abstract: Neozygites spp. are important natural enemies of several spider mites species. Isolates of Neozygites sp. from Brazil are currently being released in Africa for the control of the introduced cassava green mite (CGM). The specific name of this fungus remains unsettled although some authors have referred to it as N. floridana. We have been gathering information on the remarkable variability of specific characteristics between Neozygites isolates pathogenic to the cassava green mite and isolates pathogenic to the two spotted spider mite. In this study we report the morphological characterization and the effect of temperature on the in vitro growth of hyphal bodies among isolates with different host ranges and from different geographic locations. These information will substantiate our intention to describe the Brazilian CGM pathogen as a new species of Neozygites.
