Hirsutella thompsonii, a hyphomycetous fungus, was found attacking the citrus rust mitePhyllocoptruta oleivora for the first time in May, 1972, in the Lower Rio Grande Valley of Texas. Sharp reductions in mite populations occurred during this period. The fungus was isolated from mites collected from citrus fruits and leaves. The parasitic nature and the distribution of the pathogen are described.

Hirsutella thompsonii, champignon hyphomycète, a été isolé de l'acarien des Citrus,Phyllocoptruta oleivora pour la première fois en mai 1972 dans la basse vallée du Rio Grande au Texas. Des réductions brutales des populations d'acariens se manifestèrent à cette période. Le champignon a été trouvé chez des acariens vivant sur les fruits et sur les feuilles de Citrus. La pathogénie et la distribution du champignon sont étudiées.
