Crazy ants are in the news. The ants got their name because of their frantic behavior when disturbed. Crazy ants were inadvertently brought to the Christmas Island in the Indian Ocean by Southeast Asian traders in sea cargo a few decades ago, and they are now blamed for killing millions of red crabs indigenous to the island, which belongs to Australia. Red crabs are the keystone species on Christmas Island, and thus the need to protect them. Australian authorities are planning to import micro wasp from Malaysia to dent the population of crazy ants. Scientists believe that the wasp will be preying upon an insect that produces a sugary substance the ants consume, which will result in reducing the ants’ food supply. Critics of this policy point at problems with a similar attempt in the Thirties, when the cane toad was introduced to Queensland in Australia in an attempt to eradicate the cane beetle, which damages sugar cane crops. Instead, the toad spread across Northern Australia and damaged the native wildlife. In response to the criticism, the authorities promise careful oversight of the micro wasp. No prize for guessing the outcome of the new policy against crazy ants, though. Playing nature can have only one possible outcome—surprise. Surprise, surprise.
