Abstract: This thesis is concerned with the biology of Eriosoma lanigerum (WAA) and its parasitoid (Aphelinus mali), the impact of the pest on the crop and the effects of pesticides used routinely in South Australian orchards on both woolly apple aphid and the parasitic wasp. The study identifies current management practices of apple growers in South Australia. Aspects of the biology of WAA and A.mali are examined. Work is also done on the toxicity against WAA and A.mali of insecticides used in the control of codling moth and phytophagous mites. The effects of WAA infestation on the growth of young trees are investigated. The seasonal activity of WAA on mature trees is determined over a two season period.
