Answer:
The introduction of cane toads was done on purpose in Australia, that is, in the period of 1935 in order to fight against the growth of cane beetles in the sugarcane fields. These toads possess greater feeding capacity. These can not only consume the cane beetles, while also the other insects that affect the yields. They are toxic in nature and can kill any insect post-ingestion. Thus, they act as a useful biological insecticide that offers the safety of the crop against the insects.
