Osteospermum moniliferum is potentially susceptible to a range of control strategies, but Burgman and Lindenmayer recommended that the strategy chosen be responsive to the local situation and available resources. [5] Due to its relatively shallow root system, removal by hand is an ideal method of control.
Biological control or biocontrol is a method of controlling pests, whether pest animals such as insects and mites, weeds, or pathogens affecting animals or plants by using other organisms. [1] It relies on predation , parasitism , herbivory , or other natural mechanisms, but typically also involves an active human management role.
The Cane toad has large poison glands, and adults and tadpoles are highly toxic to most animals if ingested. 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 , notably in the case of Australia in 1935, and derives its common ...
Juvenile cane toads are often preyed on, [38] as certain Iridomyrmex species such as I. purpureus and I. ruburrus are immune to the toxins released by the cane toads. [ 39 ] [ 40 ] As a result, placing Iridomyrmex nests in habitats which house cane toads have been suggested as a method of controlling the cane toad population. [ 41 ]

The cane toad in Australia is regarded as an exemplary case of an invasive species.Australia's relative isolation prior to European colonisation and the Industrial Revolution, both of which dramatically increased traffic and import of novel species, allowed development of a complex, interdepending system of ecology, but one which provided no natural predators for many of the ...
They are also known as "the cane toad of the sky". [4] However, there is little scientific consensus concerning the extent of its impact on native species. [45] [46] The common myna was first introduced to Australia between 1863 and 1872, in Victoria, to control insects in the market gardens of Melbourne.
