A survey of aphids flying over eastern Australia on 1961

Abstract

The results are given of a year's operation of Moericke aphid traps at 12 sites in Eastern Australia. More than 60 aphid species were trapped in flight and their distribution in space and time were recorded. Criteria for making comparisons between catches at different trap sites are discussed. It was generally concluded that the major influence affecting the occurrence of species throughout the year was the prevailing pattern of climatic changes, whilst the overall geographical distribution of species seemed to be more closely linked to the distribution of exotic plants introduced by man, than to any other factor. The similarity of the Australian aphid fauna to a fractional sample of the world aphid fauna is noted.
