Cane toads were imported by the Australian Bureau of Sugar Experimental Stations to eat cane beetles. The beetles were a major pest of sugar cane and threatened to ruin the industry. The Greyback and French's Cane Beetles, native insects that naturally ate grass roots, bored into the roots of sugar cane crops and were causing the plants to die and go brown. Control with poisons like arsenic trioxide, carbon disulfide and even 1,4 dichlorobenzene was failing badly, and the success of biological control against he prickly pear led influential politicians and the CSIR to believe the toad would eat the beetles.

Unfortunately, toads cannot access adult beetles which fly away and the larvae live underground, so the experiment was a failure. European common toads (Bufo bufo) were tested for controlling grass grubs, but it was found they could not dig down to reach them - a basic quarantine process never done with cane toads.

Since none of Australia's native animals have resistance to bufotenin (unlike other places where cane toads have been introduced), they have become more of a pest than the beetles ever were. Quolls, medium-sized carnivorous marsupials, have been very badly hit by poisoning from toads and now are largely confined to Tasmania where toads cannot reach (they sink in seawater). Many snakes have also declined badly where toads are present.

Fertility control methods, though as yet unproven despite years of research, offer the only hope for control. However, I do not even know basic questions on this issue like how long poisonous toad eggs remain viable without sperm to fertilise them - I have assumed they would eventually die in the absence of sperm, but I have not found data.

The toads did not control the beetles, but they did multiply, and are still expanding their range west and south across Australia.

How were cane toads introduced into Australia?

Cane Toads in Australia...Cane Toads originally come from Hawaii, 102 of them were packed in a box and were shipped to Australia to control the cane toad beetle, this happened in 1935. The cane to toad was brought to Australia in 1935 to get rid of the Cain beetle population which got here when the Europeans brought sugar cane for sugar they said that the Cain toad had worked in other places e.g Hawaii and the Caribbean so Australia ordered 102 Cain toads to eliminate the Cain beetle without thinking of the side effectsCane toads were imported from South America to Australia because the people in Australia hate cane Beetles So they had to bring cane toads there to eat cane beetles.A good book on the subject is called Toad Rage by Morris Gleitzman.


Do cane toads have an effect on quolls?

Yes. Cane toads are a huge problem for quolls in the northern oart of Australia. Quolls are carnivorous marsupials, and many will attempt to eat cane toads. Cane toads, an introduced species, are poisonous when ingested, and so quolls can be killed for following their instincts. There is hope, however. In northwestern Australia, scientists have developed a bait from the less toxic parts of cane toads which, together with a nausea-inducing salt, is being used to give native animals such as quolls an aversion to cane toads.

Why were cane toads brought to Queensland?

Native to Central and South America, Cane toads were introduced to Australia from Hawaii in June 1935 by the Bureau of Sugar Experiment Stations in an attempt to control the native cane beetle (Dermolepida albohirtum). These beetles are native to Australia and they are detrimental to sugar cane crops, which are a major source of income for Australia.

Why did cane toads come to Australia?

The cane toad was brought to Australia to control a plague of sugar cane beetles. They were introduced into Australia by William Mungomery who was the head of the Australian Bureau of Sugar Experiment Stations in Queensland. In 1935, Mungomery travelled to Hawaii, and came back with 102 toads which were released around Cairns in north Queensland.


How did cane toads arrive in Australia?

Ironically they were introduced to destroy a cane-beetle plague. But the beetles are living in cane, where the toads cannot reach them. Also, cane beetles are too small to serve as food, so the toads left the canefields and entered forrests and swamps where they eat anything they can swallow. So recently, they are a pest themselves.


When cane toads were introduced to Australia did they serve their purpose?

Yes their introduction had a purpose. But the toads did not serve it... They were introduced in Australia to eat small beetles. These beatles were a pest to the sugar cane. But the toads are ground dwellers while the beatles live high up the plants. So eventually the toads never got to the beatles and searched for food in the surrounding forests and swamps. There they started to reproduce and scince there are no natural enemies the toads are now considered a pest themselves.
