Investigations on the natural epizootics of Cladosporium cladosporioides (Fresenius) de vries were carried out on Okra grown at Tamil Nadu Agricultural University, Coimbatore during 2010 and 2011. Observations on the incidence of mycosed mites were monitored continuously on okra at weekly interval during the study period. Occurrence of mycosis on Tetranychus urticae Koch due to C. cladsoporioides was high during third week of August 2010 (67.58%) followed by first week of August 2011 (47.24%), respectively. Fungal infection on mites had significant positive correlation with relative humidity and negative correlation with sunshine hours during the study period. An epizootic incidence of Cladosporium cladosporioides recorded on T. urticae is the first report from Coimbatore, Tamil Nadu.Keywords
