Abstract: The Parlatoria date scale insect, Parlatoria blanchardi (Targioni-Tozzetti) (Hemiptera: Diaspididae) is a serious pest on date palm trees in Egypt. The present work was carried out to study the spatial distribution and optimum sample size for monitoring of Parlatoria date scale insect, P. blanchardi on date palm trees through the two successive years of (2010/2011 and 2011/2012) at Esna district, Luxor governorate, Egypt. Data were analyzed using fourteen indices of distribution and used two methods of regression (Taylor s and Iwao s). All of the indices of distribution indicated aggregation distribution for all different stages and total population of P. blanchardi in both years and during the combined two years. Furthermore, that the regression methods of Taylor s power law (b) and Iwao s patchiness (β) were both significantly > 1, and indicating that the all alive stages of P.
