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.
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.
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 ]
Toad Day Out is a pest control event which takes place in Queensland, Australia on the 29 March of each year. Its focus is to reduce the population of the invasive cane toad. The toads are caught live and unharmed. [1] The day was originally advocated by politician Shane Knuth. [1] Toads are captured and taken to be humanely destroyed.
The cane toad (Rhinella marina), also known as the giant neotropical toad or marine toad, is a large, terrestrial true toad native to South and mainland Central America, but which has been introduced to various islands throughout Oceania and the Caribbean, as well as Northern Australia.
A young cane toad. 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.
Meat ants are able to kill poisonous cane toads, an introduced pest, as the toxins exuded by the toad, usually lethal against its predators, do not affect the meat ants. [138] Due to this, scientists in Australia have considered using meat ants as a form of pest control to reduce the cane toad population. [ 139 ]
