(A) In the early $1920$s,the prickly pear cactus was introduced into Australia. It spread rapidly into millions of hectares of rangeland,causing significant ecological damage. This invasive species was finally brought under control by introducing a cactus-feeding predator,specifically a moth species $(Cactoblastis cactorum)$,into the area. This is a classic example of biological control,where a natural predator is used to manage an invasive population.
