where were cane toads first introduced in australia?
1948
native to south and mainland middle america, cane toads were introduced to australia from hawaii in june 1935 by the bureau of sugar experiment stations, now the sugar research australia, in an attempt to control the native grey-backed cane beetle ("dermolepida albohirtum") and french's beetle ("lepidiota frenchi"). these beetles are native to australia and they are detrimental to sugar cane crops, which are a major source of income for australia. adult cane beetles eat the crop's leaves, but the main problem is the larvae, which feed on the roots. adult cane beetles have a heavy exoskeleton and their eggs and larva are often buried underground, making them difficult to exterminate. furthermore, conventional methods of pest control, such as pesticide use, would eradicate harmless species of insects as well, making it an unsatisfactory method. cane toads were to replace the use of pesticides like arsenic, pitch and copper. the success of using the moth "cactoblastis cactorum" in controlling prickly pears in australia also contributed to hopes for the cane toad.
