%X Sampling plans were developed for 2 phytophagous mites, #Mononychellus progresivus$ Doreste and #Oligonychus gossypii$ (Zacher), on cassava in Africa. Analysis of intraplant distribution showed a preference of #M. progresivus$ for the apical and middle parts of the plant, and of #O. gossypii$ for the middle and lower plant parts. Thus, the first fully developed leaf in the middle part was chosen as the common sampling unit for both species. On this unit, both species displayed aggregated distributions. The proposed binomial and enumerative sampling plans permit reliable estimates of both #M. progresivus$ and #O. gossypii$ densities. Forty fully developed leaves provided satisfactory estimates of the densities of both mite species. (Résumé d'auteur)
