Australia in the 1920s


Ecological initiatives to control pests


In 1920, the Commonwealth Prickly Pear Board was formed to investigate biological control of the prickly pear pest, which had infested millions of hectares in New South Wales and Queensland. In 1928, the board introduced a species of moth from Argentina, called Cactoblastis cactorum, to eat the prickly pears. Its success gave rise to great optimism (although at times misguided) about introducing new species to bring agricultural pests under control. Prickly pear was largely eliminated as a problem by 1934.

In 1935, the cane toad (Bufo marinus) was imported into Queensland from South America in a mistaken attempt to eradicate the cane beetle pest. The cane toads completely ignored the beetles and steadily branched out across the continent. Cane toads soon rivalled rabbits as the most noxious pest ever introduced into Australia.
