invasive cane toads

Australia's most damaging invasive species

Because of its voracious appetite, the cane toad has been introduced to many regions of the Pacific and the Caribbean islands as a method of agricultural pest control.

Native to South and mainland Middle America, imported cane toads had been used in Puerto Rico to control sugar cane pests since 1920, and an influential 1932 research paper by Raquel Dexter showed that they largely ate beetle larvae that in turn ate sugar cane.[3] Based on her findings, they were introduced to Hawaii by Cyril Pemberton in the early 1930s, and then introduced to Australia from Hawaii in June 1935 by the Bureau of Sugar Experiment Stations, now Sugar Research Australia, in an attempt to control the native grey-backed cane beetle (Dermolepida albohirtum) and French's beetle (Lepidiota frenchi).[4] Those beetles are native to Australia and they are detrimental to sugarcane crops, which are a major source of income for Australia.

The sudden inundation of foreign species has led to severe breakdowns in Australian ecology, after overwhelming proliferation of a number of introduced species, for which the continent has no efficient natural predators or parasites, and which displace native species; in some cases, these species are physically destructive to habitat, as well.

Sounds like all we need is to introduce something that preys on cane toads. That'll do 'er!
