The efficiency of bees in finding nectar sources has long been a source of wonder. Now Australian researchers have found another trick they use. They have discovered that the scent of a familiar nectar can trigger honeybees' memory of a previous route to a food source. In a report in Nature the Canberra researchers tell how they trained bees to visit differently scented sugar feeders and discovered that, even when the feeders were removed, bees could be induced to fly to these old sites by wafting the scent into the front of the hive.
