In addition to the polyphagous species described in part 2 of this 'series, only two aphids, Toxoptera aurantii and T. citricidus. are known to attack Citrus in East Africa. T. aurantii also feeds on coffee, tea and a number of wild shrubs. T. citricidus forms large colonies only on Citrus and Cape Chestnut (Calodendrum capense) and is recorded as the vector of the citrus virus "tristeza".
