Abstract
Large populations of Oligonychus yothersi (McG.) were observed on the middle, lower leaves of tea at Parinquera-acu in the State of Sao Paulo, Brazil, following a long dry and warm period. Chemical control measures were necessary. The mite has also been observed causing bronzing of the leaves of rose bushes in a garden at Piracicaba (Sao Paulo), and causing bronzing and premature falling of leaves of azaleas in Petropolis (Rio de Janeiro).
