A plant perfume that attracts female moths—a world-first attractant invented by the Cotton Catchment Communities CRC and its partner Ag Biotech Australia—is already reducing pesticide use by Queensland and NSW cotton growers.

Peter Gregg and his colleagues have developed a ‘moth magnet’ that attracts Helicoverpa, the cotton boll worm moth which causes billions of dollars of damage to agriculture world-wide.
