Abstract
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". The adults of both species are shiny black in life; the larva! Being brownish. T. citricidus has 'the third antennal segment black, except at the very base, whereas that of aurantii is white except at the tip.
