Hives ferment a yeasty brew, attract beetle pest

The honeybee's alarm signal may not only bring help, but also attract the small hive beetle. Now, an international team of researchers has found that small hive beetles can detect some alarm pheromones at levels below that detected by honeybees. The beetles associate the alarm chemicals with a go...
