In February 1982, CSIRO, in collaboration with the United Nations Development Program, made the first release of a tiny weevil, Cyrtobagus, on Binatang Lagoon in the East Sepik. The result is one of the most spectacular examples of ''biological control'' in modern times. Hundreds of square kilometres of salvinia are being destroyed by the weevils as they spread through the area. Village life along the Sepik is returning to normal.
This film is a graphic account of the story as we follow Dr Peter Room, from CSIRO''s Division of Entomology, on his historic journeys to Papua New Guinea to release the beetle and then to follow up the results.
Produced in 1985.
