Some aspects of the ecology of the citrus red mite, Panonychus citri (McGregor), in the Eastern Cape Province

The citrus red mite, Panonychus citri (McGregor), is a relatively new pest to South African citriculture, the first recorded injury to citrus trees was from Rustenberg, Transvaal in 1950 (Smith 1953). In the U.S.A. the biology of this mite has been studied by Quayle (1938), Prendergast (1938), Engli...
