Prickly pears (mostly ''Opuntia stricta'') were imported into Australia in the 19th century for use as a natural agricultural fence and in an attempt to establish a cochineal dye industry. Many of these, especially the Tiger Pear, quickly became widespread invasive species, rendering of farming land unproductive. The moth ''Cactoblastis cactorum'' from South America, whose larvae eat prickly pear, was introduced in 1925 and almost wiped out the population. This case is often cited as an example of successful biological pest control. There is a monument to the ''Cactoblastis cactorum'' in Dalby, Queensland commemorating the eradication of the prickly pear in the region. ==Species== The following ''Opuntia'' species are recorded as naturalised in Australia: *''Opuntia aurantiaca'' *''Opuntia dejecta'' *''Opuntia dillenii'' *''Opuntia elata'' *''Opuntia elatior'' *''Opuntia engelmannii'' *''Opuntia ficus-indica'' *''Opuntia humifusa'' *''Opuntia leucotricha'' *''Opuntia microdasys'' *''Opuntia monacantha'' *''Opuntia polyacantha'' *''Opuntia puberula'' *''Opuntia robusta'' *''Opuntia schickendantzii'' *''Opuntia'' sp.
