Introduced species

Since the birth of agriculture, farmers have tried to avoid using pesticides by employing various biological methods to control nature. The first method involved introducing a predator that would control pests by eating them. This was used successfully in 1925 to control the prickly pear population in Australia. The prickly pear had originally been used as a divider between paddocks. However, it eventually spread from a few farms to 4 million hectares of farming land, rendering them unusable. The Cactoblastis moth larvae was introduced to help control the situation and within ten years, the prickly pear was virtually eradicated. Further attempts at biological control weren't so successful. When farmers tried to eliminate the cane beetle by introducing the South American cane toad, the results were catastrophic. The cane toad did not eat the cane beetle and the toad population spread rapidly leading to the decline of native species of mammals and reptiles. J
