Phyllocoptruta oleivora

Hirsutella thompsonii Fisher (Fig. 7) was not formally identified and described until many years after its role as an important pathogen of the citrus rust mite Phyllocoptruta oleivora) was first suspected (Speare and Yothers, 1924 Fisher, 1950). Undoubtedly, the species was an unrecognized component of the friendly fungi of Florida citrus farms, discussed earlier. However, it was not until relatively recently that its actual impact on pest populations was quantified and its commercial potential as a biocontrol agent of both eriophyid and tetranychid mites was realized (McCoy, 1981). This resulted in the launch of a commercial mycoinsecticide, Mycar, for early application in citrus orchards to...
