The study was realized at the Experimental Station Rammel Mesquita Farias in the municipal district of Parnamirim, Rio Grande do Norte State, Brazil, in the period from April, 2000, to March, 2001. The observations were concerned to the disease progress (incidence and severity) on the coconut leaflets, as well as the occurrence of hiperparasitism on the causal agent. In all observations the disease incidence was equal to 100%. The progress of the severity presented different tendencies: increasing - from April to July, 2000 and decreasing from this month to Mach of 2001. In the same way were the tendencies of the hiperparasitism incidence. The disease severity and the hiperparasitism incidence were correlated positively and significantly with the climatic variables, pluviometric precipitation and relative humidity and, negatively with the temperatures.
