In the early 1960s George Bornemissza, then a scientist at the Australian Government’s premier research organization, the Commonwealth Scientific and Industrial Research Organization (CSIRO), suggested that dung beetles should be introduced to Australia to control dung – breeding flies. Between 1968 and 1982, the CSIRO imported insects from about 50 different species of dung beetle, from Asia, Europe and Africa, aiming to match them to different of climatic zones in Australia. Of the 26 species that are known to have become successfully integrated into the local environment, only one, an African species released in northern Australia, has reached its natural boundary. Introducing dung beetles into a pasture is a simple process: approximately 1,500 beetles are released, a handful at a time, into fresh cow pats in the cow pasture. The beetles immediately disappear beneath the pats digging and tunnelling and, if they successfully adapt to their new environment, soon become a permanent, self – sustaining part of the local ecology. In time they multiply and within three or four years the benefits to the pasture are obvious. Yes if the statement reflects the claims of the wri
