This week: aphids eat crops but what will eat aphids? The story of the search for the insect that could take on a whole field of the number one wheat pest. And Karina Kelly reports on Australian efforts to save the giant green turtle from extinction. Tourism and hunting have led to a 90 per cent drop in the numbers of the turtles in the last 30 years. The creatures have a life span of 150 years but don't start breeding until they are 50. Off the coast of Queensland scientists are trying to find out more about the sexual habits of the turtles so that a strategy for their survival can be planned.
