Dispersion pattern for adult citrus red mite(CRM), Panonychus citri(McGregor) using by Taylor's power law(TPL) and Iwao's patchiness regression(IPR) was determined to develop a monitoring method on citrus orchards, on Jeju, in Autumn season, during 2001 and 2002. CRM population was sampled by collecting leaves and fruits. The relationships of CRM adults between leaf and fruit were analyzed by different season. The regression equation for CRM adults between leaf(X) and fruit(Y) was ln(Y+1)=1.029ln(X+1). The density of CRM ws higher on fruit than on leaf according to fruit maturing level. TPL provided better description of mean-variance relationship for the dispersion indices compared to IPR. Slopes and intercepts of TPL from leaf and fruit samples did not differ between developed units and surveyed years.
